You are running in UMS mode and it looks like you may have fglrx leftovers still installed. Make sure all of fglrx is removed and make sure radeon is loaded in KMS mode.

**pjsm** · 07 October 2011, 08:11 PM

Flgrx was never installed so it shouldn't be a problem.

How do I make sure it's in KMS mode? I had "options radeon.modeset=1" in radeon-kms.conf in /etc/modprobe.d, which I though was supposed to force KMS mode. It doesn't seem to be working though, so is there something else I am supposed to do?

Thanks

radeon.modeset=1 should be on the kernel line in your grub.conf.

**pjsm** · 07 October 2011, 11:37 PM

I tried adding radeon.modeset into the kernet grub line just by hitting e during boot, and editing the line there. There was no change to performance, and the xorg.0.log record was exactly the same as well. ANy other idea?

Thanks

OK, a change.

I uninstalled an old nvidia driver (for a card that no longer works)

I then added radeon.modeset into the grub boot again, and got this in xorg.0.log

The section starting with drmopendevice I have not noticed before.

I have just found this in the kernel log:

Code:

This seems to suggest that modesetting is available, but the xorg log still continues to say that modesetting isn't available.

**pjsm** · 09 October 2011, 06:04 AM

I looked in the kern.log and it said that modesetting is enabled, but somehow in xorg.0.log it says that modesetting is not enabled.

Ideas?

**agd5f** · 10 October 2011, 10:29 AM

Make sure the radeon kernel module is loaded before you start X.

**pjsm** · 11 October 2011, 05:37 PM

I found a page that talked about a "race" issue where x starts up before the driver is initialised. That page suggested adding modprobe radeon into /etc/init/gdm.conf, but this didn't work for me. I have also tried adding "radeon" into /etc/modules, but that also didn't work. According to dmesg | grep drm, the kernel modesetting is initialising at around 13 seconds, Xorg log is saying that it can't initialise drm at around 23 seconds. Is there a way of delaying x from starting (this system often boots automatically due to a BIOS wakeup, and always logs in automatically), or something else I cna try?

thanks
