--- Comment #19 from r...@alum.mit.edu ---
I don't have a backtrace, but with openSUSE 42.1 and 42.2, this is reproducible
with otherwise identical KDE, X, Mesa, and kernel stacks other than the X
server. With 1.18 and 1.17 servers, this doesn't happen; with the 1.19 server,
this happens on the order of every 5-30 minutes but with no otherwise
predictable pattern.
The one predictable occurrence is during early startup; after I log in, it
freezes during the splash screen.
The reliable way to clear it is to switch virtual terminals and back.
I'm using the (free) radeon driver with a Radeon HG 5870 adapter.
I've backed off to 1.18 because this is too annoying.
There is a workaround: create an xorg.conf (or put in xorg.conf.19) the
following:
Section "Device"
Identifier "Videocard0"
Driver "radeon"
Option "DRI" "3"
EndSection
This appears (at least on initial testing) to avoid the problem.
Unfortunately, it causes severe screen flickering with LibreOffice 4.2.7 (which
don't ask why, but I need this) that renders *that* completely unusable.
