can't login into GNOME session with radeon driver

[Alex Ivasyuv]

Binary package hint: xorg

After today updates (xorg system, dri, etc...) my gdm not start. I reboot and in recovery mode remove /etc/X11/xorg.conf and re-run Xorg -configure. The system detected radeonhd driver for my video system. As this driver has no even dri support yet (even if it enable), I changed driver to radeon. GMD login screen appear, but if I enter password, X restart and login screen appear again. So with radeon driver it's not work now. It work with radeonhd driver, but it very-very laggy (I have no normal 2D-acceleration).

If I use radeon driver, and try to switch console, X system freezing (see screenshot).

Thanks, could you also attach your gdm logs? They're in /var/log/gdm/.

Does "radeon" work if you turn off DRI or desktop effects?

I don't have enable effects, as radeon doesn't allow me to do this (even if it was working).
I created xorg.conf via running Xorg -configure. By default there all options comments (dri, etc).

Should I set DRI options to false with radeon driver?

I only try to enable dri for radeonhd, but it's not work, e.g. X not start.

[Alex Ivasyuv (industral)]

OK, I found that using "true" or "false" it's wrong. It should be "0" or "1".
So, using:

Option "DRI" "0" with radeon (by default it enable) driver fix this issue.
Option "DRI" "1" with radeonhd (by default it disable) driver make issue occur.

As conclusion, problem in DRI.
