[Message part 1 (text/plain, inline)]

Hi,

I installed guix sd on my desktop machine yesterday, and tried to add
the %desktop-services so I could use openbox.

When the system boots, Xorg segfaults. I have an ati graphics card that
doesn't work with free drivers, so I expected the server to fallback to
vesa or something else. I attached the xorg log and my system
configuration.

Let me know if you need anything else (I am not on this mailing).

regards,
Julien

Xorg seems to be using the ATI driver, which was just recently added to
the default set of Xorg drivers (commit
3126fd8820e8c30e27ef978d66dced8763d04905).

Could you try reverting that commit and see if it gives you a working
Xorg over VESA/FB or something?

Is xf86-video-ati known to be unstable?

Thanks,
Ludo’.

OK so the problem may be unrelated.

Did you have success with previous versions of xorg-server or the
drivers?

(FWIW I use 1.18.1 successfully with xf86-video-intel.)

So what do you use on other free distros?  VESA?  Anything special is
needed in xorg.conf?

Thanks,
Ludo’.

Closing because I can't reproduce it anymore.
