Also, the same happens when suspending or changing to console mode (attached X.0.log is the failing one): (EE) RADEON(0): [dri] RADEONDRIGetVersion failed because of a version mismatch. [dri] This chipset requires a kernel module version of 1.17.0, [dri] but the kernel reports a version of 2.0.0.[dri] If using legacy modesetting, upgrade your kernel. [dri] If using kernel modesetting, make sure your module is [dri] loaded prior to starting X, and that this driver was built [dri] with support for KMS. [dri] Disabling DRI. The solution that works for me is to force loading the radeon module in /etc/modules. This should not be necessary, udev should autoload radeon on boot. Can you attach dmesg after removing radeon from /etc/modules? Cheers, Julien signature.asc Description: Digital signature

This should not be necessary, udev should autoload radeon on boot. Can you attach dmesg after removing radeon from /etc/modules? From the dmesg timings, I can see that the drm initialization starts at [9.797560] when radeon module loaded in /etc/modules (see drm messages in original bug). From the dmesg output below, I see that drm initialization starts at [ 22.688394]. So, it seems to me that udev is not loading the driver properly. I can easily detect this, because when radeon module is loaded properly before X, the text mode resolution changes. Also, if I boot with (recovery mode), the radeon module is not loaded (only if added in /etc/module). That's weird... Can you get the contents of /sys/bus/pci/devices/:01:00.0/modalias, make sure it looks like pci:v1002d95C4sv1043sd19D3bc03sc00i00 and then give us the output of /sbin/modprobe -R -b $modalias. This *should* show radeon. If not then something's screwy in your modprobe config. If yes then I don't understand why udev isn't loading it.

You were right, it was an issue with my modprobe config. I had an old file /etc/modprobe.d/display_class.conf that blacklisted the display device: install pci:v*d*sv*sd*bc03sc*i* /bin/true Removing this file, there is no need to load the radeon module in /etc/modules. I guess you should mark this bug as invalid. Thanks for your help. Aleix -- To UNSUBSCRIBE, email to debian-bugs-dist-requ...@lists.debian.org with a subject of unsubscribe. Trouble?
