1002:9641 [Lenovo ThinkPad E525] Screen black on resume

[Geoff Teale]

I did the kernel smoke test for the quantal kernel on precise.

I can suspend and resume however when I resume I the screen stays black. It looks like the backlight isn't coming on, but it's noteable that I don't see anything on my external screen either. I can see consoles on my external monitor (over HDMI) and if I disconnect the HDMI cable and reconnect it then I am also able to see my Unity session on that screen. This issue is present with both the quantal kernel and the stock 12.04 one.

WORKAROUND: Use fglrx.

I had to install kernel-3.2.0-0.rc5.git1.1.fc17.x86_64 from Rawhide to make KMS work on the integrated video.

I tried suspend/resume by closing the lid, suspend worked. Resume woke up the
machine but left the screen black. dmesg for the suspend/resume is attached.

Would it be possible for you to test the latest upstream kernel? Refer to https://wiki.ubuntu.com/KernelMainlineBuilds . Please test the latest v3.5kernel[0] (Not a kernel in the daily directory) and install both the linux-image and linux-image-extra .deb packages.

Once you've tested the upstream kernel, please remove the 'needs-upstream-testing' tag. Please only remove that one tag and leave the other tags. This can be done by clicking on the yellow pencil icon next to the tag located at the bottom of the bug description and deleting the 'needs-upstream-testing' text.

If this bug is fixed in the mainline kernel, please add the following tag 'kernel-fixed-upstream'.

If the mainline kernel does not fix this bug, please add the tag: 'kernel-bug-exists-upstream'.

If you are unable to test the mainline kernel, for example it will not boot, please add the tag: 'kernel-unable-to-test-upstream'.
Once testing of the upstream kernel is complete, please mark this bug as "Confirmed".

Thanks in advance.

[Joseph Salisbury (jsalisbury)]

This issue appears to be an upstream bug, since you tested the latest upstream kernel. Would it be possible for you to open an upstream bug report at bugzilla.kernel.org [1]? That will allow the upstream Developers to examine the issue, and may provide a quicker resolution to the bug.

If you are comfortable with opening a bug upstream, It would be great if you can report back the upstream bug number in this bug report. That will allow us to link this bug to the upstream report.

I have the exact same problem here but with a radeon HD 7310. I can try patches.

Attached are the logs from dmesg (before and after running pm-suspend) and Xorg.0.log (there were no messages after resuming from suspend)

[Vladimir Mityukov (mityukov)]

I'm not sure if I have the same issue. In particular, I could not find this error in my dmesg:
..
[drm:radeon_acpi_init] *ERROR* Cannot find a backlight controller
..

But I do have the issue that my laptop does not wake up fully (the screen is black).

There is some noise starts in the notebook and led indicators start blinking, but the screen does not turn ON.

I know, there are many possible reasons, but it worked with Catalyst, so, I think it has to be connected to video driver (dri, kms, xf86-video-ati, whatever..).

Any process? This is the most annoying thing about using Linux..

[bruno pennec (bruno-pennec)]

Same issue for my A8-450M laptop with Integrated or Discrete GPU set.
I made some tests from kernel 3.8.0 to 3.12-RC6 on Ubuntu.
I got same result with other distro like ArchLinux or Fedora.

Some other tests on my main kernel 3.11.6 (Ubuntu PPA)
(CPU and GPU firmware has been updated to latest version)

 - After suspend and resume, with ssh I can check brightness control on /sys/class/blacklight/radeon_bl0/brightness and change the value but nothing change on screen (always black screen)
 - no syslog entry give information on the problem
 - no more information with drm.debug on kernel
 - fglrx doesn't have the same problem, suspend and resume work fine
   (but fglrx don't allow to change brightness).

So, this concern seems to come from the drm driver and not from kernel or acpi,
but I don't have enough knowledge to go further to identify the root cause in xorg

[Lbdkmjdf (lbdkmjdf)]

I'm using kernel 3.13-rc0 from: http://kernel.ubuntu.com/~kernel-ppa/mainline/drm-next/2013-11-14-trusty/
3.12.0-996-generic #201311140516
and this is still happening...
I guess I'll have to go back to fglrx.
I wished I could help devs, but this is driving me crazy. Not being able to resume from suspend is why I wanted to test the open-source driver in the first place...

[Geoff Teale (tealeg)]

So, updating my BIOS, sadly, did not fix the problem. The result was exactly the same. I suspend the laptop, then resume it. The machine resumes from suspend in every respect except that it doesn't turn the backlight on the screen back on.

With the new BIOS, the output of `sudo dmidecode -s bios-version && sudo dmidecode -s bios-release-date` is:

[Geoff Teale (tealeg)]

Hi.

I've confirmed that the bug still exists with kernel 3.13.0 (and tagged as requested) - I will try with a clean install from the daily ISO when I get a little time to do so, hopefully in the next few days.

[penalvch (penalvch)]

Geoff Teale, did this problem not occur in a release prior to Precise?

[Geoff Teale (tealeg)]

I don't think I ever had a release prior to precise running on the laptop -
I was using the development ISOs when I first got the machine about 2 years
ago. As I recall it was really hard to get it running at all (I had to use
the server CD) - things have improved since then ;-)

Geoff Teale, could you please provide the information following https://wiki.ubuntu.com/DebuggingKernelSuspend ?

[Geoff Teale (tealeg)]

Attached wakeup file.

[Geoff Teale (tealeg)]

This attachment contains the full output of dmesg following the "resume-trace" procedure described on https://wiki.ubuntu.com/DebuggingKernelSuspend

[Geoff Teale (tealeg)]

Christopher. Thanks for your help. That kernel bug was marked as resolved, but the DRI bug (already linked here and on the kernel bug) is still in New status and many people are reporting the same issues there still. Is it really worth re-raising the Kernel bug?

[penalvch (penalvch)]

Geoff Teale, given the DRI report is similar problem, different hardware model, and it has many "Me too!" comments, those types of reports tend to be lost in the shuffle.

However, a couple of follow up questions:
1) Just to clarify, did the patch mentioned in https://bugzilla.kernel.org/show_bug.cgi?id=46241#c8 address your problem?
2) Did this problem not occur in a release prior to Precise?
3) Does fglrx provide a WORKAROUND?

[Geoff Teale (tealeg)]

Christopher.

The answers:

1. No.
2. I'm having to think back two years now, but I believe I had to install from Ubuntu Server and install FGLRX to get it working on oneiric and alpha versions of precise. I know for sure that the desktop install CD would hang prior to precise. Would you like me to try install oneiric server on it again to see exactly what happens?
3. Yes, suspend/resume with FGLRX does work perfectly on both this AMD A8-3500M and on my wife's AMD A10-5750M based machine.

[penalvch (penalvch)]

Geoff:

>"Would you like me to try install oneiric server on it again to see exactly what happens?"

No, this should be enough info. Given the upstream patch didn't address your issue, and the upstream bug was closed, it woudn't hurt utilizing the upstream format in https://wiki.ubuntu.com/KernelTeam/KernelTeamBugPolicies#Kernel.org_Format to e-mail linux-pm CC Alex on how the upstream patch didn't address the issue.

Same problem here running on a HP Laptop Pavillion G7 with AMD A6-3400M CPU/GPU.

Currently running 3.12.5 kernel from openSuse Tumbleweed, though ive had this problem for ages.

[Hcb-o (hcb-o)]

This bug is really old and really annoying as it makes the laptops unusable for suspend -- what kind of traces would be required to understand the core of the problem, from what I can tell the display engine is in a severely hosed state, but I lack documentation to understand what is wrong.

Does setting out a bounty for this bug help? I'm willing to immediately cash in at $300.

I also want a status on this. This is 1% to make Linux 100% perfect.

[Austin Hoppe (austin-hoppe7)]

Kernel 3.14-rc8 (with PRIME) + mesa 10.2-git (radeon driver with kms and dpm)
Still the same issue, suspend + resume works fine but the laptop's screen does not turn back on. Using an external monitor confirms that the system itself is functional after resume. When running fglrx, there is no issue.

BUT I can make the screen turn on after suspend with the next command:
sudo pm-suspend --quirk-test --quirk-s3-bios

so if you can try and this work maybe we can kick this issue.

whoa, that worked as well for me! I'll try to dissect unless someone else jumps to it, and then make good on my promise above :)

maybe the same issue? https://bugs.freedesktop.org/show_bug.cgi?id=42960

also, isn't pm-utils somehow deprecated?
if we add the parameter in /etc/pm/config.d/ will the command "systemctl suspend" be able to turn on the screen? i think that "systemctl suspend" doesn't rely on pm-utils

I looked in the pm-utils sourcecode, and adding acpi_sleep=s3_bios to the cmdline fix it for me.

You can read a little about it here: https://www.kernel.org/doc/Documentation/power/video.txt

Seems to work for me too. I'm sure one of Alex's patches helped out too, so thank you Alex.

I do get this on resume, but that's probably for another bug:
[ 117.375124] [drm:atom_op_jump] *ERROR* atombios stuck in loop for more than 5secs aborting
[ 117.375127] [drm:atom_execute_table_locked] *ERROR* atombios stuck executing E442 (len 2585, WS 4, PS 4) @ 0xEB2C

Awesome. To spell it out a little more explicitly, here is what I did (Arch x86_64 3.14-mainline) to have this apparently accomplished automatically from now on:

sudo su

echo 'ADD_PARAMETERS="--quirk-test --quirk-s3-bios"' >> /etc/pm/config.d/00-fix_dv6z_suspend_screen

pm-suspend --quirk-test --quirk-s3-bios --store-quirks-as-lkw

Which should save the quirks, perhaps with some redundancy. Checking the contents of the (new)

/etc/pm/last_known_working.quirkdb

file should show the matches made against your particular system, especially e.g. hardware and firmware details. I guess these could be patched into (for my HP at least)

/usr/lib/pm-utils/video-quirks/20-video-quirk-pm-hp.quirkdb

with some of the returned information, given that this file is supposed to have a fairly up-to-date {white,black,broken}-list.

Obviously follow this only at your own risk, etc. I have no idea how this would work when it comes to fglrx, or even how stable it is against kernel/pm/upower/whatever updates. Here are some more good references for information:

GREAT, it works for me, thank you very much!
I did try pm-suspend with different flags some months ago.. I guess my testing was too conservative :(
@ <email address hidden> and <email address hidden> , thank you too! and once again, thanks AMD devs :)

Hmm. I just did:
sudo nano /etc/default/grub
found GRUB_CMDLINE_LINUX_DEFAULT and added acpi_sleep=s3_bios just before quiet
ctrl+o and ctrl+x
sudo grub-mkconfig -o /boot/grub/grub.cfg

I see now... I DID test the '--quirk-s3-bios' flag, but I need '--quirk-test', which is not documented in the manpage...

from pm-utils-1.4.1/README.debugging:
"* To override the usual quirk filtering (for kernel modesetting, binary drivers, and exotic hardware), pass --quirk-test along with any other quirks you want to try. This may make your system crash in new and exciting ways by conflicting with the kernel when suspending or resuming, but is very useful for debugging. You have been warned."
Oh, well, I'm happy that someone found a solution and shared it with us all :D
