Hello,
I just had a look at corresponding launchpad bug (LP #446578) and is seems
that having kernel mode setting resolves the problem. As far as I understand,
the driver is not enabled in linux-image-2.6.31-trunk-686 because it is a
staging driver.
My question is anybody tested it in Debian ? I mean tested libgl1-mesa-dri 7.6
with kernel mode setting, the radeon driver and KDE ?
Best regards
