The various logs
Dear AMD Team,
unfortunately installation of your amdgpu-pro-18.40-676022-rhel-6 driver in
CentOS 6.10 goes wrong at many spots.
So far I had been using fglrx happily, but now I needed Vulkan support, so I
decided to upgrade.
Since I got a AMD Radeon R9 290X I followed instructions at
https://amdgpu-install.readthedocs.io/en/latest/
and used
amdgpu-pro-install --opencl=legacy
the script ran through, I rebooted, and got a black screen.
Logging in remotely and looking at /var/log/Xorg.0.log I saw lots of entries
about fglrx.
Since your instructions don't mention uninstalling old drivers, and your
amdgpu-pro-install doesn't complain, I don't think that's my fault.
Next, I uninstalled fglrx, to be sure also amdgpu-pro-uninstall, rebooted, and
went for another
amdgpu-pro-install --opencl=legacy
After another reboot, a 'startx' finally gave me a running X-server, but no
OpenGL/GLX (running glxinfo yielded 'no GLX visual found').
Next I checked what amdgpu-pro-install did to my /etc/X11/xorg.conf and found
this:
Section "ServerLayout"
Identifier "Main"
Option "AIGLX" "false"
EndSection
Section "Device"
Identifier "Videocard0"
Driver "radeon"
EndSection
This doesn't look like it's a proper xorg.conf for amdgpu-pro. After some
googling, I replaced xorg.conf with this file:
/usr/share/X11/xorg.conf.d/00-amdgpu-pro.conf
After an X-server restart, 'glxinfo' in a terminal gave a different error:
libGL error: failed to open drm device: Permission denied
libGL error: failed to load driver: radeonsi
libGL error: failed to open drm device: Permission denied
libGL error: failed to load driver: radeonsi
libGL error: failed to open drm device: Permission denied
libGL error: failed to load driver: radeonsi
Whenever there is a permission problem, I try again as 'root', and indeed,
things worked.
After some googling, I did
cd /dev/dri
ls -l
crw-rw----+ 1 root video 226, 0 Nov 27 23:06 card0
crw-rw----. 1 root video 226, 64 Nov 27 23:06 controlD64
crw-rw----+ 1 root video 226, 128 Nov 27 23:06 renderD128
Then I did
chmod a+rw *
and got
crw-rw-rw-+ 1 root video 226, 0 Nov 27 23:06 card0
crw-rw-rw-. 1 root video 226, 64 Nov 27 23:06 controlD64
crw-rw-rw-+ 1 root video 226, 128 Nov 27 23:06 renderD128
And magically, after many hours of fiddling, OpenGL and OpenCL worked for a
normal user. Yupppie!
So I figured it's time to file a bug report, ended up at
https://amdgpu-install.readthedocs.io/en/latest/install-bugrep.html#generating-a-bug-report
This page shows countless commands to run to save my system config. And
amazingly, each command is shown with a '$' in front.
This means that I cannot just copy the entire script into a terminal, but
instead have to do it line-by-line manually, or copy it to a text editor and
cut the $s out.
Seriously?
Hope this report helped to improve things...
Regards,
Elmar
