I bought a Radeon R9 280x. Without thinking I popped it into my machine and tried to run X. I'm not sure if this *should* theoretically work but it definitely did not on my end.

I have 'xf86-video-amdgpu' installed from Slackpkg. The error given when i do startx is

I have tried the following:

- uninstalling and reinstalling the amdgpu package

- xinit, which gives the same error

- pgrep x shows four processes running, but they're not on pstree and pkill x doesn't work. 'pgrep X' shows nothing.

- deleting /etc/modprobe.d/blacklist and /etc/X11/xorg.conf (as well as xorg.conf.nvidia-xconfig-original, conf.original-0, conf-vesa, and conf.backup)

- then running xorgsetup, it passes just fine. running startx after gives the same error, redoing xorgsetup and then rebooting and then starting x also gives the same error.

- uninstalling xfce just gives an xfce-related error:

So I'm at a loss here. Help very much appreciated.


EDIT: fixed by reinstalling the MESA package. leaving this up for anyone in the future looking

Normally, yes this should work. However, based on your error message and how you fixed it, it likely means you installed the proprietary nvidia driver. They actually replace files from mesa with their own versions, so other video cards can't use them without reinstalling the mesa package.

Anyway, I'm glad you solved it and thanks for posting your solution

If you use the --uninstall option on the Nvidia driver it will offer to restore the original files.
Just FYI.
