gpu-manager is responsible for overwriting your X config file. Commenting out the "start on" lines at the top of gpu-manager's upstart script located at /etc/init/gpu-manager.conf will temporarily disable gpu-manager and prevent xorg.conf from being changed.

Changing the gpu-manager to let the xorg.conf unchanged caused a freeze of the system.

I tried the new beta driver from amd catalyst 14.4 (Beta) from the AMD site where explicitly my two cards are listed and it works perfectly.

Both cards HD8650G (1Gb) and the internal HD8670M are working now and the xorg.conf will not be overwritten by booting any longer.

It seems that Ubuntu 14.04 64bit is not compatible with the amd-catalyst-13.12-linux-x86.x86_64 .

I am currently using amd-driver-installer-14.10-x86.x86_64 which is a beta release and latest rc.

I have the same issue but on a Dell laptop, with NVIDIA GeForce GT 525M and Intel video card. On the Ubuntu 14.04 alpha and beta stages I didn't had any issue, but with the "stable" version xorg.conf is deleted after boot. Now I have some annoying behavior with my external monitor connected through HDMI.
The gpu-manager.log looks like this:

Grub config for booting wo. AMD catalyst Edit (1.2 KiB, text/plain)

Hi,

as written before I could fix the problem on my HP Pavilion 17-e026sg 17,3" AMD A10-5750M with Radeon HD8650G and Readon HD8670M.

Here comes what I did to install a fresh Ubuntu 14.04LTS 64bit:

I guess that you already have a USB start disc ready and will start with the first boot from this stick:

1. Start your PC end hit ESC to select from the boot menu and different boot option
2. select USB EFI HDD (or similar)
3. When UBUNTU menu comes up don't boot live disc boot directly in installation mode
4. from here on follow the instructions until the installation is finished
5. Ubuntu seems to fail on booting the first time after the installation but it's only the X-Server because it can't handle the grafic cards. It will show you that you have to reconfigure your X-server but don't proceed this!
6. Switch from error screen to terminal (strg+alt+F2) and wait until terminal screen comes up. Not sure if it is ctrl+alt+F2 for you ?!
7. When terminal is open login with your user credentials
8. Enter 'sudo nano /etc/default/grub'
9. Nano editor will open the Grub configuration. Enter there 'nomodeset' in line GRUB_CMDLINE_LINUX_DEFAULT="quiet splash" before 'quiet splash'. (please se grub.txt attached)
10. enter 'strg+O' (see menu at the bottom of nano) to save and 'strg+X' to exit
11. reconfigure Grub with command 'sudo update-grub'
12. reboot your PC and it should start in X mode
13. Download latest 64bit catalyst from amd site (latest stable is 14.4 )
14. change authorization in terminal for this file by entering 'sudo chmod 777 amd-catalyst-14-4-linux-x86-x86-64.zip'
15. unzip file and run from terminal by entering 'sudo ./amd-driver-installer-14.10.1006-x86.x86_64.run' (you must be in the same folder where the file is stored!!!!)
16. you can decide if you want to do a custom installation or default. I recommend to use the default way!
17. when installation is finished go to terminal again and remove the 'nomodeset' from grub by entering 'sudo nano /etc/default/grub' edit it and close it again. Run 'sudo update-grub'.

The installation script will do everything what is necessary. It will also create a new xorg.conf which will not be overwritten any longer

Reboot your PC. From now on everything should work as planned

You can switch between the cards by entering ' sudo aticonfig --px-igpu' for the internal device or 'sudo aticonfig --px-ggpu' for the dedicated grafic-card. After entering the command you have to reboot your machine and it will restart in this mode until you switch back.

Alternative you can use the amd control-center. Enter 'sudo amdcccle' in the terminal and you will have a graphical tool to configure your cards.

Hopefully this will help you to fix the issue. For me it worked.

Uwe

Please look at this beautiful log! Everything was fine, fglrx was enabled and loaded, amd card detected, no other cards are present... And gpu-manager got a great idea to completely remove xorg.conf and install mesa alternatives instead of pretty working fglrx.

This. Is. Not. Funny.
For me I decided to use 'nogpumanager' parameter as this piece of software is a trash. Sorry for my English.

How is this not a high priority issue? Deletion of a working config file should be a high priority, period, shouldn't it? I had a working 14.04 system and ran updates with the result of breakage all over the system (intel drivers don't run in SNA mode right for me, need UXA to work properly). Note that is upgrade not dist-upgrade. I'm happy to help troubleshoot this but it really seems a bad policy to give no method of keeping a working config. Hope the comments help,

I agree that this bug should be a higher priority. I have a cluster built on Quad CPU SuperMicro H8QME2 motherboards with hex-core Opteron CPUs . With 12.04LTS, the motherboard ATI graphics worked fine as the machines are BOINC number crunchers. The motherboards also have NVIDIA Telsa GPU co-processor boards for GPU number crunching, which I have not been able to get working for several weeks since upgrading to 14.04LTS. They all worked fine with 12.04 LTS, but this "new feature" of 14.04 LTS is absurd.

I could not figure out what was happening the xorg.conf files. I have to load the NVIVIDA drivers for CUDA/OPENCL processing to work, but needed the display to be active on the motherboard ATI graphics , as these Telsa cards are strictly for crunching and have no display output capability. This "new feature" kept forcing the systems to try to display to a screen attached to the TESLA cards.

If the problem can't be fixed easily, an simple work-around for users should be provided until the problem can be fixed.

I managed to track down the original problem reported by Uwe.

@VasiaUVI: can reproduce the problem and attach your /var/log/gpu-manager.log after that please?

@Grief: there's no need to be rude, regardless of what your native language is.

@Oleg: if I understand correctly, in your case the problem is that the gpu-manager overwrites your xorg.conf but you can still use the fglrx driver, right?

@Trev: there are issues with UXA and hybrid graphics on many systems. If you file a separate bug report about SNA, and point me to it, I'll have a look at it.

@Greg: can you reproduce the problem and attach your /var/log/gpu-manager.log after that please? I'm working on some code which should only enable the GPUs that are connected to outputs. Your log could help me understand your use case.

@all: I'm working on a fix. As a workaround, you can simply pass "nogpumanager" on boot, the gpu-manager won't start. Hybrid graphics will probably fail though.

The same happens for my system (Dell M6800 with Nvidia Quadro K3100M).
I found on the web somebody who stated to have the solution.
Solution provided, remove the ~/.config/monitor.xml file.
Tried that but then the light went out completely (no graphics anymore, only a command line prompt).
Even restorting the monitor.xml file could not make it work again.

Will try the trick with the /etc/init/gpu-manager.conf file.

I'm another person being harassed by gpu-manager. Every couple reboots it decides the system configuration has changed and removes xorg.conf. That causes the machine to end up in an unusable state, because that xorg.conf was crucial to working around an issue with the NVIDIA driver (which I'm stuck with for various reasons), and so I'm left with blank screens and even the text consoles are trashed.

This machine is using Xen and has two video cards with one of them being "hidden" for passthrough to a VM, which may be something gpu-manager just can't make sense of. Its logs usually indicate that it thinks the number of cards has changed, even though I haven't touched the hardware.

I had already commented out the "start on" lines in gpu-manager.conf and that did *not* stop it from breaking my system configuration, so I guess now I'm going to try commenting out the entire file.

Marc Defossez (defossez) wrote on 2014-08-23:

Ok, I commented the "Start on" lines at the top of the /etc/init/gpu-manager.conf file.
This is what I did:

My Laptop has two video cards a Intel Haswell and a Nvidia Quadro K3100M
The laptop was working with the nouveau drivers on the Intel card and that worked OK.
I upgraded the Intel drivers with the latest from the Intel web site and everything still worked OK.
Intel download site: https://01.org/linuxgraphics/downloads/2014/intelr-graphics-installer-1.0.6-linux
The gpu-manager log file reported that the was a Nvidia card but no xorg.conf file and stopped with "nothing to do"

As soon as I installed the nvidia proprietary drivers the systems dd not work in graphical mode anymore.
It booted on the command line and a popup box appeared reading "The system is running in low graphics mode - You must
configure it yourself". Examining the xserver log file reveals several complaints about the xorg.conf file.
That file is not in correct format and by that the systems doesn't boot graphically.

Modified/commented the first lines of the gpu-manager.conf file
Modified the xorg.conf file and rebooted.

Machine still starts in command line mode (with low graphics popup box).
Examining the xorg.conf file shows that something modified it again and it has a wrong format.

I'm back to zero.

Just a comment that I never saw gpu-manager *modify* xorg.conf -- it just renamed it to xorg.conf-DATE leaving me with no xorg.conf at all (which in my case was enough to cause major problems). Commenting out all of the lines in gpu-manager.conf seems to have stopped it from running, which solved my issue for now.

If something is actually changing the content of your xorg.conf file, I'd be more suspicious of the graphics driver installer or perhaps some helper program that came with the driver.

Just been hit by this. Spent all day debugging graphics problems, only now to discover that something has renamed my xorg.conf. I need 'Option "PageFlip" "false"' with nouveau to get decent performance, something decided that it knew better than me how to configure my hardware :(

Graphics card is:

@all: I tracked down and fixed the issue here. I plan to deliver an update soon. In the meantime you can disable the gpu-manager by passing "nogpumanager" on boot (you can also set it permanently in /etc/default/grub).

Please do not edit the upstart job (/etc/init/gpu-manager.conf)

BTW I'm going to second the "nogpumanager" approach, because I just rebooted and even with a completely commented-out gpu-manager.conf it still ran and decided the number of cards had changed and removed my xorg.conf leaving my system unusable. Putting "nogpumanager" into the kernel command line via /etc/default/grub did the trick. gpu-manager still runs, but now it explicitly logs that it was disabled by the kernel parameter.

This bug was fixed in the package ubuntu-drivers-common - 1:0.2.98

---------------
ubuntu-drivers-common (1:0.2.98) utopic; urgency=medium

  * gpu-manager.c, gpu-manager.py:
    - Add support for testing core alternatives. This will be needed
      by fglrx.
    - Add the --backup-log parameter. This is only used for debugging
      and disabled by default.
    - Fix a regression that caused the gpu-manager to switch to mesa
      after enabling fglrx on hybrid systems (LP: #1310489). Also
      add a test case so that we don't regress in the future.
    - Check that either fglrx or nvidia is set in xorg.conf when
      xorg.conf is needed.
    - Check if kernel modules are blacklisted before choosing the
      driver (LP: #1310489).
    - Enable only GPUs with open drivers that have connected outputs.
      Attaching to GPUs that have no connected outputs would result
      in a black screen.
    - Allow RandR offloading even without bbswitch (LP: #1349282).
    - Fall back to mesa when failing to enable prime.
    - Do not try to enable prime if the nvidia driver is older than
      331.
    - Do not abort if the settings for prime cannot be found.
      Try creating the file before failing.
    - Avoid false positives of unloaded modules.
    - Use the cleanup attribute.
    - Always use snprintf instead of sprintf.

Hallo Alberto!

Thanks a lot for your work on this bug!

I have a question:
Does your solution also apply when both graphic cards are from AMD?

My laptop has both graphic cards, integrated and discrete, from AMD.

I'm asking because you wrote:
> [Test Case]

Thanks in advance!

Hallo Alberto!

Thanks a lot for your work on this bug!

I have a question: 
Does your solution also apply when both graphic cards are from AMD?

My laptop has both graphic cards, integrated and discrete, from AMD.

I'm asking because you wrote:

Thanks in advance!

@Philipp: yes, I think the problem (hence also the fix) could affect systems with multiple AMD systems, although I haven't reproduced it on such systems yet.

Hello Uwe, or anyone else affected,

Accepted ubuntu-drivers-common into trusty-proposed. The package will build now and be available at http://launchpad.net/ubuntu/+source/ubuntu-drivers-common/1:0.2.91.7 in a few hours, and then in the -proposed repository.

Please help us by testing this new package. See https://wiki.ubuntu.com/Testing/EnableProposed for documentation how to enable and use -proposed. Your feedback will aid us getting this update out to other Ubuntu users.

If this package fixes the bug for you, please add a comment to this bug, mentioning the version of the package you tested, and change the tag from verification-needed to verification-done. If it does not fix the bug for you, please add a comment stating that, and change the tag to verification-failed. In either case, details of your testing will help us make a better decision.

Further information regarding the verification process can be found at https://wiki.ubuntu.com/QATeam/PerformingSRUVerification . Thank you in advance!

3. Install fglrx and reboot
4. Check if the driver is enabled

Actual result:
From the output of unity_support_test and gpu-manager.log, fglrx is loaded and it's using the discrete (AMD) video card.

On A+A config I found although fglrx will not be disabled by gpu-manager, xorg.conf will still be regenerated, and with the regenerated xorg.conf there is no graphics switching option in amdcccle (amd control center).

Alberto Milone (albertomilone) wrote on 2014-09-05:

#34

The log attached by Po-Hsu shows that fglrx was correctly enabled on a system with hybrid graphics.

@Yu Ning: that is ok. If there is no switching option in amdcccle, that is a bug in the amdcccle binary (nothing I can do about it). The gpu-manager worked correctly by enabling both AMD GPUs with fglrx.

Hallo Alberto,

I followed your instructions, including the installation of the
ubuntu-drivers-common from the proposed-archive.

The result was, that the xorg.conf wasn't changed anymore after reboots.

BUT the output from /var/log/gpumanager.log says: Disabled by kernel
parameter "nogpumanager"
Before that I had the gpu-manager disabled via the grub parameter
nogpumanger to prevent my xorg.conf from being overwritten. But
following your instructions, I deleted this parameter and updated grub.
I doublechecked my /etc/default/grub: There's no such parameter.
Did this happen intentionally via the new ubuntu-drivers-common-package
or did I miss something?
Is it possible that there's a lock-file somewhere not working right?

What exactly is the downside of a not-working gpu-manager when
proprietary drivers are installed?

Thanks a lot in advance

Best regards

Philipp

Well it wasn't removed by me.

This problem only seems to happen when there is an update for the
graphics drivers. This kicks off DKMS on next boot, so perhaps
gpu-manager is looking for the driver before DKMS has rebuilt it?

Comparison of the xorg.conf files generated by the new(not working) and old(working) gpu-managers Edit (1.3 KiB, text/plain)

Hi Alberto on my machine NVIDIA Optimus setup is no working even with the latest version of "ubuntu-drivers-common" i.e.:(1:0.2.91.8), although it does work with older version of this package i.e. (1:0.2.91.4). I have noticed one difference in the xorg.config file generated by the new and old versions of gpu-manager. Basically when using NVIDIA GPU as the main one i.e. "prime-select nvidia" the old gpu-manager sets the "Driver" value for the "intel" device to "modesetting", but the new gpu-manager sets the "Driver" value for the "intel" device to "intel".

As far as I can understand by looking into the X server log setting the "Driver" value to "intel" instead of "modesetting" prevents the X server from correctly identifying the screen on my laptop giving a black screen on boot.

Please see the file attached to this post for a comparison of xorg.conf files generated by the new and old gpu-managers.

GPU Manager logs Edit (4.9 KiB, text/plain)

This problem is not fixed, or at least not fully. I am running Xubuntu 14.04 on the 3.13.0-47-generic kernel. I have Nvidia optimus graphics on my laptop with dual Intel GMA HD and Nvidia GeForce GTX 860M graphics cards. I have the ubuntu-drivers-common version 1:0.2.91.8, nvidia drivers version 331.113, and nvidia-prime version 0.6.2.

I've noticed the following:

1. When I have the Nvidia prime profile selected and reboot, the system leaves my xorg.conf alone. The gpu-manager.log says that I previously had 2 cards, I have 2 cards now, and nothing changed.

2. When I switch to the Intel prime profile from the Nvidia prime profile and reboot, the gpu-manager.log says I previously had 2 cards and I have 2 cards now and the system did not change, but IT DELETES xorg.conf anyway!

3. Whenever I reboot with the Intel prime profile in effect, the gpu-manager.log always says I previously had 1 card, I have 2 cards now, and the system has changed. Then it renames xorg.conf to xorg.conf.currentdate.

4. When I switch from the Intel prime profile to the Nvidia prime profile, the gpu-manager.log says I previously had 1 card, I now have 2 cards, and the system has changed. It then tries to remove xorg.conf, which isn't there anyway, and then regenerates xorg.conf. One weird thing is it usually says Found "/dev/dri/card0", driven by "i915", but in this case only it says Found "/dev/dri/card1", driven by "i915". Why would the card number change?

Without knowing anything about the internals here, it sure looks like there is a bug in how gpu-manager counts cards, or if it gets that info from something else, then that something has a bug.

@John: that sounds like a bug in the intel driver then. Please attach your /var/log/Xorg.0.log and /var/log/Xorg.0.log.old after reproducing the problem.

@Keith: I think the main problem there is that we have to re-enable the disabled GPU on shutdown in order to avoid problems with the BIOS. This is why two GPUs are detected on boot. I'll think of a workaround. As for test-case 2), I'll look into that, as gpu-manager always says in the log when it is removing or renaming the xorg.conf (and the log shows no trace of it).

Thanks Alberto.

FYI, the log excerpts I included are not in the exact same order as the 4 cases I listed. I did put text above each log section indicating what I was trying at the time. Test case 2 in my posting corresponds to the 3rd block of log messages in the attachment.

So far, I've never seen a case where gpu-manager renamed the xorg.conf file without logging a message that it was doing so.

This bug is still affecting me. I have a desktop with two nVidia cards in an SLI configuration. I need a custom xorg.conf to support my 1440p monitor, but my xorg.conf gets renamed to xorg.conf.yyyymmdd almost every reboot.

That's a separate case.

Can you attach your working xorg.conf and the file that the "sudo
nvidia-bug-report.sh" command creates, please?

Odds: I don't really need the integrated intel GPU, but I have to use, because the GT630 wasn't be able to start as display driver along the GTX980. I have had two options for the display section: integrated or GTX 980. I want to use GTX980 for computing only, so I had to use the integrated one. Then I faced this xorg.conf issue.

Alberto Milone (albertomilone) wrote on 2015-05-13:

The problem is that, as long as a display is connected to the integrated GPU, gpu-manager will use it and offload rendering to one of the nvidia GPUs. I'm not sure how SLI works with that. You can try booting with the "nogpumanager" (from the grub menu), then generate the xorg.conf that you need and restart X, to see if that works.

@Alberto
Yes, I've tried the "nogpumanager" solution same time I send you my issue and it worked.
Anyway, I tried to charge the display tasks to either the integrated Intel or the Nvidia GT 630 drive to relieve the GTX980 to achieve more resource for computing capabilities.
1. BIOS doesn't start the display with Nvidia GT 630 along the 980.
2. If I start with the integrated Intel drive, system starts virtually appropriately, but X Server charge 6-7% of memory of GTX 980, I don't know why?
Any help would be highly appreciated, and thank you for your undiminished efforts.

Dear Alberto,
Previously I said "nogpumanager" solution works but it was right on 14.10!
Unfortunately when I reinstalled 14.04 LTS and modified /etc/default/grub:
GRUB_CMDLINE_LINUX_DEFAULT="quiet splash nogpumanager",
it doesn't result in any changes in manner of xorg.conf overwriting issue.
It doesn't work.

The "nogpumanager" parameter has been supported since ubuntu-drivers-common 1:0.2.89 in 14.04. I'm not sure why that doesn't work for you. Did you update the grub menu with "sudo update-grub" ?

I'm on Linux Mint with the 352 xorg-edgers driver (I have to go this route because of Quadro) in Linux Mint 17.2.... I have this problem, too, except it doesn't overwrite my xorg conf in /etc/X11/xorg.conf. In 17.1 I can restart and it will retain my settings, but once I turn off the monitor, the settings just reset. Now in 17.2, if I turn off the monitor and reboot, the settings reset. xorg.conf remains untouched...

Hi, I think I just got bitten by this same bug. Runing ubuntu 14.10. I installed nvidia drivers on Dell Vostro notebook. After this, any attempt to log in to Xwindows results in a loop and returns to the login window.

I tried following the suggestion here and booting with "nogpumanager". It seems to have broken something else and now the machine gets stuck in booting, even after removing it again.

It seems this Bug also affects ATI/AMD full sized graphic cards. I've had a problem on 4 different machines since 14.04 was released where it is impossible to enable both ATI GPUs. I have one machine running just 1 ATI card and that machine is functional, it has 6 xorg.conf.currentdate files in etc/X11. The other test 14.04.1 systems on spare hard drives installed yesterday have just one xorg.conf.currentdate files. I have been trying to say with AMD Catalyst 14.6 as that works best with the OpenCL Apps the machines run, however, I have the same problem with the FGLRX driver in Additional Drivers currently installing AMD-APP 1729.3. I have tried dozens of clean, fresh installs of different versions of 14.04.x, same problem in each one.

How do I fix this so it works the way it did in 12.04.x? I'm currently running 12.04.5 on my main machine with an AMD 7750 and 6970 simply because I can't get both cards enabled in any version of 14.04.x.

I can confirm this Bug is indeed the reason my 4 Desktop machines can't enable the second ATI graphics card. I made the "a)" changes mentioned here, <http://askubuntu.com/questions/453902/problem-in-setting-up-amd-dual-graphics-trinity-radeon-hd-7660g-and-thames-ra/477006#477006>, copied my xorg.conf file from my working 12.04.5 machine to the 14.04.1 HDD, deleted all the rest, and upon Boot both my Cards were enabled. Both cards appear in clinfo, and I can issue commands in aticonfig without receiving an Error. What other, if any, problems will this Edit create?

I suspect if my 4 machines are suffering from this Bug then it's very probable that many more are also effected. I'd hate to generalize, however, I would guess that Most machines running some version of 14.04 are effected. This week I downloaded and installed the latest version 14.04.3 and it too has this Bug with my machines.

It would be nice if this were fixed, and I could run kernel 3.13.xxx without having to make this Edit.

Over the last day I decided to try Ubuntu 14.10 to see if this Bug was still present. First attempt using the Ubuntu supplied driver in Additional Drivers was a failure. The installed driver contained AMD-APP 1526.3 which should be Catalyst 14.6. With this driver installed an incomplete xorg.conf was generated missing the Monitor/Screen sections, only the Device section was present. Only One card was present in clinfo, this also created numerous Errors using aticonfig and after a few attempts at reverting drivers and trying one from AMD the result was an unusable system claiming my password was suddenly invalid. Reading from AMD, is Cat 14.6 even compatible with 14.10? From here; http://support.amd.com/en-us/kb-articles/Pages/Latest-LINUX-Beta-Driver.aspx
System Requirements: Before attempting to install the AMD Catalyst™ Linux graphics driver, the following software must be installed:
Xorg/Xserver 7.4 and above (up to 1.15)
Linux kernel 2.6 or above (up to 3.13)
My updated 14.10 has kernel 3.16.

On the second attempt, with a fresh install, I used Catalyst 15.5 from AMD First and that system seems to work fine. Both AMD cards are enabled , both appear in clinfo, and there isn't any problems using aticonfig. It would appear this Bug isn't present in 14.10 on this machine. I haven't tested the others. Unfortunately 14.10 has reached the End of Support and is not in consideration and my experience with catalyst 15.7 while running 12.04.x was not satisfactory, so, Ubuntu 15.04 is out as well.

Also affected, although nothing to do with a multi-gpu system. Mint 17.3 (64-bit, Cinnamon) and a local /etc/X11/xorg.conf to slow down my crazy-fast Logitech mouse. Installing fglrx renamed xorg.conf to xorg.conf-DATE (and put nothing in its place).

Not a huge problem in this case, but certainly rather uncourteous of it. If this is an involved problem, perhaps at least this specific situation could be worked around by not moving xorg.conf out of the way if it isn't being replaced by anything. That is, I imagine it could be generally troublesome to merge a local configuration, but merging with a new /empty/ configuration is not. If a new xorg.conf is in fact generated, maybe a user warning if an old one was also found...

@HuaiDan: what do you mean by "failsafe values"?

@g hartog: if you think the problem described in this bug report is still there, then please explain the situation, and attach your /var/log/gpu-manager.log after reproducing the problem.

On Ubuntu 17.04 gpu-manager overwrites xorg.conf
Does this bug still persist?

Ubuntu 16.04.2 (installed from minimal install disk -- if it matters).

2 Nvidia gtx 1070 cards and on board intel one.

/etc/X11/xorg.cof gets rewritten at each reboot, with or without nogpumanager specified in /etc/default/grub

Found an (idiotic but) efficient workaround!

protect /etc/X11/xorg.conf to be overwritten using:
chattr +i /etc/X11/xorg.conf

Then, don't forget to unprotect it and protect it back each time you want to modify it.
