<pre>Approximately once per day, the system experiences a random reoccurring crash:
All windows and buttons freeze in place and become unusable, while only the
mouse cursor remains possible to move around. After a few seconds, the monitor
starts turning itself on and off several times (standby mode). Finally I either
find myself back to the login manager, or the monitor permanently stays off...
which of the two is completely random. If I manage to kill X11 in time (control
+ alt + backspace) and try logging back in, desktop effects will sometimes not
work although they report no error as to why, whereas at other times the image
just freezes again and I'm forced to restart anyway.
Today I discovered an important detail: The crash is not limited to KDE desktop
effects, unlike most crashes of this sort and what I initially suspected to be
the case; I had compositing disabled for several hours (alt + shift + F12), yet
the exact same crash occurred! Although the freeze is rare and probabilistic so
it's impossible to reproduce on demand, the trigger seems to be some sort of
window activity, such as a system tray notification or window popping up...
also starting up certain games may cause an immediate system freeze.
My OS is Linux openSUSE Tumbleweed, running on top of KDE / Plasma 5. I use the
free video drivers and default system packages of this distribution. My card is
a Radeon R7 370, GCN 1.0 on RadeonSI and the radeon module (no amdgpu support
yet). The issue survived through several kernel updates, indicating it's likely
not part of the Linux kernel directly. Current versions or relevant packages
(monitored at <a href="http://tumbleweed.boombatower.com">http://tumbleweed.boombatower.com</a> ):
kernel: 4.10.3
mesa: 17.0.1
llvm: 3.9.1
xorg-x11-server: 1.19.2
xf86-video-ati: 7.8.0</pre>
