That would be a possible explanation, yes... however I'm not completely
sure... any way to try and confirm this diagnostic for sure ?

I'd be perfectly happy to have one bug less open on the kernel, but I
think there's a problem here that is not fixed at all. Of course, I
could manage to workaround by passing args to the kernel, but that looks
like a regression from end user perspective : how comes that without KMS
things work OK, and with, it doesn't ? Maybe it could be reassigned to
another faulty package ?
Maybe the problem is not with the kernel and with the X driver, then, as
I have :
Option "IgnoreEDID" "on"
Option "PanelSize" "1280x1024"
If I get it right, with KMS, if 1280x1024 is not detected as a valid
mode by the kernel, but then, shouldn't the PanelSize setting be
observed anyway by the radeon driver ?
Should I reassign to xserver-xorg-video-radeon instead (I'm reopening
Thanks in advance for your opinion.
