Upgrading Ubuntu 18.04 disables GPU hardware acceleration

Status changed to 'Confirmed' because the bug affects multiple users.

On Xubuntu, can you try downgrading the package xubuntu-default-settings from version 18.04.2 to version 18.04.1? Maybe it's related to what I'm seeing in bug #1752798

(you can find the older package here: https://launchpad.net/ubuntu/+source/xubuntu-default-settings/18.04.1/+build/13749132 )

I'm facing huge difficulties after this upgrade. All games I'm running with wine stopped working. I did not test others. They start, but I either get a black or purple window, no image. Can somebody point me the right way to debug and solve this?

I have an AMD Radeon HD 7850 installed.

Making a basic test, it seems to perform better with software rendering... ?!?

$ glxgears -info

I'm experiencing the same issue - no hardware acceleration.

I have an askubuntu.com question open with plenty of information and logs.
https://askubuntu.com/questions/1029205/video-playback-performance-issue-ubuntu-18-04

The original bug I reported was a duplicate of bug #1751414. It has been
fixed. Lately I've upgraded from 17.10 to 18.08 for my laptop. I don't have
this issue. My laptop has Intel GPU though.

Confirmed here too. Instead of using my Intel 520 HD, the system is using: "llvmpipe (LLVM 6.0, 256 bits)" (The details section from GNOME Center).

Xorg log file, containing some error messages "No input driver specified".

Also here, with a Radeon R7.

My problem was solved by the fix suggested in this bug:

https://bugs.launchpad.net/ubuntu/+source/nux/+bug/1767468

I don't know if mine is the same problem as reported here, but worth a try.

The fix mentioned in #1767468 did not fix this for me (AMD Radeon 7950). Also installing libegl-mesa0 does not fix the issue.

Installing libegl-mesa0 fixed the problem for me.
Kubuntu/KDE, AMD Radeon 7950

Fix from #1767468 also doers not work for me. Intel HD 520

echo $LIBGL_ALWAYS_SOFTWARE gives me 1. Why?

/etc/X11/Xsession.d/50_check_unity_support sets LIBGL_ALWAYS_SOFTWARE to 1.

After removing this, my glmark2 went up from 260 to 1800 :-)
Without paying anything.

Same problem here. After upgrading my laptop from Lubuntu 16.04 to Lubuntu 18.04, there is no hardware acceleration anymore. AMD STONEY was perfectly capable of this on the older release.

glxinfo shows:
OpenGL renderer string: llvmpipe (LLVM 6.0, 128 bits)

/var/log/Xorg.0.log shows:

[ 16.679] (EE) AMDGPU(0): eglGetDisplay() failed
[ 16.679] (EE) AMDGPU(0): glamor detected, failed to initialize EGL.
[ 16.685] (==) AMDGPU(0): DRI3 disabled
...
[ 16.692] (II) AIGLX: Screen 0 is not DRI2 capable
[ 16.692] (EE) AIGLX: reverting to software rendering
[ 16.699] (II) IGLX: enabled GLX_MESA_copy_sub_buffer
[ 16.700] (II) IGLX: Loaded and initialized swrast
[ 16.700] (II) GLX: Initialized DRISWRAST GL provider for screen 0

Nothing in the kernel log indicates that there is a problem with the amdgpu driver.

Tried creating a xorg.conf and forcing DRI to 3, but no dice.

LIBGL_ALWAYS_SOFTWARE is not set, there is no /etc/X11/Xsession.d/50_check_unity_support, so it's probably not bug #1767468.

For me, "apt-get remove libnvidia-gl-390" solved it. No idea how it came to be installed, but for some reason the active EGL driver was nvidia, and that interfered with the X start sequence.

I had this problem, too. journalctl -b|grep glamor showed this:

/usr/lib/gdm3/gdm-x-session[2205]: (EE) modeset(0): glamor initialization failed

which is why gnome-shell was falling back to llvmpipe. However, there was some funny business going on with my libGL installation, because ldd /usr/bin/glxinfo showed:

 libGL.so.1 => /usr/local/lib/libGL.so.1 (0x00007fe67e633000)
 libGLX.so.0 => /usr/local/lib/libGLX.so.0 (0x00007fe67dccd000)
 libGLdispatch.so.0 => /usr/local/lib/libGLdispatch.so.0 (0x00007fe67da16000)

meaning I must have manually built and installed versions of libGL/X at some point. I deleted the libGL/X libraries and the xorg folder from /usr/local/lib and after a reboot I now have intel mesa graphics again.

please check if libnvidia-gl-390 is installed:

apt-cache policy libnvidia-gl-390

and if so, this is a dupe of 1770913, you want libegl-mesa0 and libglx-mesa0 installed instead..

the nux issue is bug #1768610

I encountered same problem, and I found the work around.

I believe this was because libglx from xorg over-written the one from amd/nvidia.

For people using nvidia graphic cards, you can do:

sudo mv /usr/lib/xorg/modules/extensions/libglx.so /usr/lib/xorg/modules/extensions/libglx.so.bac
sudo ln -s /usr/lib/nvidia-396/xorg/libglx.so /usr/lib/xorg/modules/extensions/libglx.so
Then restart.

I belive amd users can do the similar thing.

Thank you @xjbhenry (xjbhenry)!

His fix [21](https://bugs.launchpad.net/ubuntu/+source/xorg/+bug/1752938/comments/21), helped me for my NVIDIA card.

Instead of "llvmpipe (LLVM 6.0, 256 bits)" the active OpenGL renderer is now:

$ glxgears -info
Running synchronized to the vertical refresh. The framerate should be
approximately the same as the monitor refresh rate.
GL_RENDERER = GeForce 940M/PCIe/SSE2
GL_VERSION = 4.6.0 NVIDIA 396.37
GL_VENDOR = NVIDIA Corporation

Can confirm that the fix from xjbhenry worked for me as well (previously the system was 16.04, then 17.?? and then upgraded to 18.04).

Yes, happened to me also. Kubuntu 18.04.1

Yesterday (Nov 27) suddenly (after auto upgrade of the system) nvidia stopped working (switched to nouveau, probably).
Upgraded to Kubuntu 18.10
This actually made the situation even worse - stuck on 640x480 resolution.
Had nvidia-390 installed at the moment, but the system wasn't using it.

After some looking around, installed:

sudo apt install nvidia-dkms-410 xserver-xorg-video-nvidia-410 nvidia-kernel-source-410

which made the situation look better: resolution was again native (1920x1200) and nvidia-settings launched and showed 410 driver running.
But in the Steam games, it showed that llvm driver was being used. And games such as Wolfenstein New Order (uses proton wine) didn't even launch.

After some more fiddling around, actually using the Kubuntu GUI tool (System Settings > Driver Manager > Nvidia > 410) fixed the situation. Apparently the GUI tool does it somehow better than installing the nvidia package manually.
