Package: linux-2.6
Version: 2.6.32-15
Severity: normal

Hi.

Since the latest radeon X driver has entered testing, KMS is enabled on my machine, which results in display resolution badly configured with my monitor. I used to have 1280x1024 and no longer have (the fallback 1024x768 is set).

The dmesg messages about EDID being wrong show the problem.

Maybe this is linked to a KVM display switch being present ?

In any case, this is all fine again if I change modesetting to off in /etc/modprobe.d/radeon-kms.conf.

Thanks in advance.

Best regards,

So in summary your kvm switch doesn't pass edid along, so the kernel has
no way to know what resolution the monitor supports, so it falls back to
a presumably safe 1024x768 resolution.  I don't think there's a bug
here, so I suggest you try setting the wanted resolution on the kernel
command line (video=1280x1024 should work).  Closing this bug, thanks
for your report.

Cheers,
Julien
