Bug Description

On a certified Dell PowerEdge T620 server (http://www.ubuntu.com/certification/hardware/201207-11426/)

The matrox video card is not recognised:

Thus xserver is not hardver accelerated.

Also /dev/dri and /dev/dri/card0 is missing.

kernel module mga is not loaded, although if i manually load by modprobe it works fine
modprobe mga

I should mention that it was working flawlessly in 12.04, we had harware acceleration with MGA driver at 1920x1080@60hz resolution.

Reading documentation on the mga_drv.so and checking the source files of xserver-xorg-video-mga_1.6.3-1build1_amd64.deb I see that matrox driver has a built in support for EXA in config.h

#define USE_EXA 1

/* Build support for XAA */
/* #undef USE_XAA */

/* Version number of package */
#define VERSION "1.6.3"

However it seems that it is not activated or checked at runtime, any clues how this could be activated? It might bring back the lost functionality of XAA acceleration.

makes it worse than normal software render.

It results in hanging X without disabling Compsite/DownloadFromScreen. Disabling Composite, DownloadFromScreen results in fully corrupted screen, disabling UploadToScreen helps a little, however screen is still corrupted (moving a window over another leaves traces in the inactive windows behind).

The remaining acceleration

is just as slow as normal render => EXA + matrox card is not usable

Having the same problem on a Dell PowerEdge T420, 2D acceleration is not working on 14.04, whereas on 12.04 it worked just fine.

Hi,

Actually if you read through my report I finally figured what is the
problem. It is not ubuntu's fault. Xorg upstream simply decided to rip XAA
from Xorg 1.13, and 14.04 has Xorg 1.15 or something like that. So
basically in 12.04 there was no hardware acceleration either unless you
defined 1208x1024 which fits in matrox 200ge's memory for framebuffer. This
option is still ok on 14.04 so if you don't need 1920x1080 then it should
be reasonable quick (in my case I have a big monitor with FHD resolution so
I wanted to use it like in 12.04 where XAA could handle the desktop pretty
fine at this resolution.

Anyway, I did a nasty hack and avoiding the dependency hell (downgrading to
older X would make million otherwise working packages to change as well) so
I simply copied some files from 12.04 precise:

the files were:
/lib/x86_64-linux-gnu/libudev.so.0*
/usr/bin/Xorg
/usr/bin/cvt
/usr/bin/gtf
/usr/lib/xorg/modules/*

This downgrades Xorg to precise latest with XAA. To avoid breaking the X
system with later X upgrades you have to hold the following packages:
xserver-xorg-core
xserver-xorg-input-evdev
xserver-xorg-input-mouse
xserver-xorg-input-vmmouse
xserver-xorg-video-mga
xserver-xorg-video-vmware

Then just restart X and you are enjoing mga200 with XAA and enough
performance for 1920x1080p

I am attaching the tar.gzipped files from precise I saved for later for you
in case you wanna experiment. If you are going to apply it, backup the
files which will be overwritten for any case.

regards
Zoltan

I am having exactly the same issue as this on two brand new Dell PowerEdge R360 which I am setting up for the first time. This server is also certified for use with 14.04 LTS http://www.ubuntu.com/certification/hardware/201207-11432/

I tried to apply Zoltan's hack but ended up with a system that won't boot. I guess this is something to do with the fact that Grub is using the framebuffer otherwise I can't see how the changes would stop even a text screen appearing.

In the end I installed 12.04 which works almost flawlessly (resizing windows is still painfully slow). However given these are new servers I would like to start them off with the latest LTS.

Zoltan if you read this please could you give any hint why we are getting different results with the hack?

Hi,

Problem could be that you have other packages installed in the xorg-driver
package which were pulled automatically when you installed X. That means
you have probably other modules and dependencies unresolved. What I did was
first of all removing all unecessary xorg driver packages, xorg modules
which has nothing to do with this configuration anyway. Then I copied only
the corresponding package content from 12.04 (that is in my hack tar.gz).

My package list is therfore pretty lean:
dpkg -l | grep xorg
ii xorg
1:7.7+1ubuntu8 amd64 X.Org X Window System
ii xorg-docs-core
1:1.7-1 all Core documentation for

Personally, I am not necessarily interested in getting 3D acceleration supported for such an old card (and for a server!). *However*, I'd like basic graphic functionality to work decently; right now I got that by installing xubuntu-desktop, but it'd be generally cool if compiz/gnome would disable cool effects automatically, based on available hardware.

Presumably Ubuntu devs will not be interested in this. It needs reporting by everyone to the Xorg developers to get their attention. How does one do that?

Does anyone know WHY they decided to rip out XAA (whatever that is)?

Find a way to workaround.

I have a PowerEdge R620 which installed a Ubuntu 12.04 TLS. And I found the screen refreshing became very slow. So I share the same issue with yours.

First,then we have to install vesa driver:
sudo apt-get install xserver-xorg-video-vesa

Then, for some of the Ubuntu release don't have a xorg.conf, so I have to generate one with following steps:

1.switch to console mode: Alt+Ctrl+F1

I did an online chat with Dell to see if they new anything about this and they could not help. Here was there response:

"Ok. Well, I had them review the article and they see many vendors having the same issue. We don't have any updates / patches for the Matrox graphics card for this kind of issue. Were feeling that this is a desktop OS that is likely a little more graphics intensive than what the server mobo onboard video can do."

They had the linux group review this bug. BTW, window 7 and windows 8.1 work fine with this video card and mobo is a short for motherboard.

We have put in an inexpensive nvida card in our servers if we need to use the gui to get around this issue.

Same problem with a Dell PowerEdge R720, video card Matrox Electronics Systems Ltd. G200eR2
I try many ways but no one can be work fine with the ubuntu 14.04 ,
when i google the G200eR2's driver, i found a solution with this card, remove the mga driver!

sudo apt-get remove xserver-xorg-video-mga

it will remove the xserver-xorg-video-mga and xserver-xorg-video-all
then reboot
now the window not slowly, and screen only has a 800x600 @75hz , but it work fine

i hope this way can help other people

We too have the same problemwith ubuntu 14.04 LTS on DELL poweredgeR520 as well as on poweredge R320. The display is very slow with terrible framerates. I have also updated the ubuntu to 14.04.2 LTS but still the problem exists. Please suggest a work around for this issue.

Celsius (celsius-netbel) wrote :

Same problem here on a certified PowerEdge r820 with Ubuntu server 14.04.2, no GUI installed, only CLI.

The framerate is very slow, using commands like 'ls' or 'less' is almost painful. Adding vesa or mga drivers didn't change a thing. I cannot put a personalized xorg.conf since xorg-server is not even installed.

I found two separate workarounds (not fixes) to this:

1. install openssh server and log into the server from another machine. Everything works fine, fast and responsive.
2. modify /etc/default/grub to reduce the resolution of CLI by editing the line GRUB_CMDLINE_LINUX_DEFAULT="" into GRUB_CMDLINE_LINUX_DEFAULT="splash vga=1024x768x24". Then run sudo update-grub and reboot. CLI is now low resolution but fast and responsive.

I didn't try with higher resolution yet. I think I'll settle for using SSH anyway.

Celsius (celsius-netbel) wrote :

Note that if you apply solution 1 and 2 above, you get the best of both: you can still log with SSH with high resolution (full HD here) *and* have a responsive low-resolution local terminal on site.

Short version: kernel module driver "mgag200" did the trick for me. In kernel config, it is represented by CONFIG_DRM_MGAG200.
http://cateee.net/lkddb/web-lkddb/DRM_MGAG200.html

I found a bug that is relevant to this one: https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1642470 It says that the kernel module "mgag200" was blacklisted from kernels due to this bug: https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1042903 I tried manually compiling the driver as a module, adding it to a kernel and it worked.

I had problems with MGA G200e [Pilot] ServerEngines (SEP1) card. I tried Zoltán's X.org regression hack, I also tried using a recompiled up-to-date mga_drv.so, the library in xserver-xorg-video-mga, where the maintainers claim to support G200e chip (https://cgit.freedesktop.org/xorg/driver/xf86-video-mga/, commits from July 2016). Nothing worked. I am, however, just an intermediate user, so I might have made a mistake somewhere. I also do not know the difference between a kernel driver, X.org driver, and how they interact together and how they are used. Therefore I will trust someone more knowledgeable to put this all together, and I am just going to describe what I did to make it work :-)

As a reference, I did a fresh install of Linux Mint 18.1 MATE, where the GPU was unclaimed:

$ uname -a

Then I tried two approaches, both worked.

1. the easier way is to compile and install just the module mgag200. I downloaded the sources and headers for the current kernel, compiled and installed the module, and then added it in the initramfs image. Then, after reboot, it worked. Here are the resources I used:

http://askubuntu.com/questions/168279/how-do-i-build-a-single-in-tree-kernel-module
http://askubuntu.com/questions/676707/how-to-load-a-module-in-initrd

In the first one, do not forget to use your kernel version and the path to the module (drivers/gpu/drm/mgag200). Also it is probably more convenient to use "$ make menuconfig" instead of editing the .config file with vi (you need the ncurses package though). In the menu, find Graphics Drivers --> Graphics Support --> Kernel modesetting driver for MGA G200 server engines, and enable it as a module. When updating initramfs, it might be necessary to specify the kernel version, for example $ update-initramfs -u -k 4.4.0-66-generic. If you have multiple kernels, the command will tell you which initramfs it updated.

The result after a reboot:
$ uname -a
Linux rack3test 4.4.0-66-generic #87-Ubuntu SMP Fri Mar 3 15:29:05 UTC 2017 x86_64 x86_64 x86_64 GNU/Linu...

Had the same problem on a Dell PowerEdge T430 with Ubuntu 16.10.
Installing module mgag200 as suggested by Ivo Straka's (approach n. 1) worked for me. I followed the recipe in

 http://askubuntu.com/questions/168279/how-do-i-build-a-single-in-tree-kernel-module

just changing the kernel number, etc.

For reference, a couple of users have been experiencing the same issue on HP ProLiant MicroServer Gen8, which use Matrox MGA G200EH, the original culprit that caused the module mgag200 to be excluded from the kernel years ago.

In the linked topic, I put together a step-by-step walkthrough through installing the mgag200 module for Ubuntu or Ubuntu-based distros like Mint. Some users might find it helpful.

Unfortunately, only one novice user tried this on HP Gen8 and apparently it did not work. I am not sure whether the mgag200 module just does not work with G200EH yet or whether there was some mistake made in the approach either by me or the user. It would be very helpful for someone to test this with this specific chip and report in more detail.

Installing module mgag200 as suggested by Ivo Straka's (approach n. 1) worked for me.

But as Giorgio Signorini comment #61, after installed mgag200 module and set xorg driver to mgag200 and restart X.
In /var/log/xorg.0.log, there will have somes errors like "Could not load driver maga200", and finally fall back to xserver-xorg-video-mga if installed.

Actually, in xf86-video-mga 1.6.5(https://cgit.freedesktop.org/xorg/driver/xf86-video-mga/) has added support for g200e, while in ubuntu 16.04 only with 1.6.4 version(https://launchpad.net/ubuntu/+source/xserver-xorg-video-mga), and 1.6.5 only for Zesty(https://launchpad.net/ubuntu/+source/xserver-xorg-video-mga/+publishinghistory).

This is because of dependency problem, or not? Since I'm new to linux, maybe who could build xf86-video-mga 1.6.5 in ubuntu 16.04 or give some ideas about how to build?

My problem is that in a xrdp session, "xrandr -v" reports: "server report RandR version 1.1."

After following steps, it still report RandR version is 1.1

0. load mag.ko
1. build and load maga200.ko
2. build mag_drv.so 1.6.5 (downloaded from (https://launchpad.net/ubuntu/+source/xserver-xorg-video-mga/+publishinghistory).

3. restart x by
   sudo /etc/init.d/lightdm restart

I check the /var/log/Xorg.0.log and it shows "RandR 1.2 Enabled" and mge_drv version is 1.6.5
and lchw -c display shows maga200.ko is loaded correctly.

I really don't know what else should be done to solve this.
