then would be:

Adding comment 7's 50-device.conf made a 120 byte smaller log, but with same tail here pasted.

Felix, perhaps you did not re-installed xf86-video-ati -- You are receiving this mail because: You are on the CC list for the bug.

Felix, perhaps you did not re-installed xf86-video-ati

I definitely didn't. With 'Driver "modesetting"' in 50-device.conf I expect xf86-video-ati's radeon to be ignored, which is what happens. Maybe there is a 32bit vs 64bit difference here? -- You are receiving this mail because: You are on the CC list for the bug.

rpm --changelog -q xf86-video-modesetting | head -n3 package xf86-video-modesetting is not installed

xf86-video-modesetting is not installed because it was merged into the xserver package more than two years ago, which made it the default. All xf86-video* are optional, and for nearly all the most common, non-ancient gfxchips, not required. (In reply to Stefan Dirsch from comment #18)

At least we now have a workaround for Mindaugas' 32bit machine from 2005. Dumb slow, but what can we do? Nobody will still look into RS400 issues. Seriously.

Since it doesn't happen to me on KDE3 using xf86-video-radeon, maybe it should be looked at by KDE and/or SDDM people. I think if this is reproducible on antiX and reported there it will get fixed, but according to distrowatch, antiX doesn't offer Plasma. -- You are receiving this mail because: You are on the CC list for the bug.
