Hello everyone,
Following the latest Qubes update the Qubes seems again to randomly
freeze every 1-2 day making it unusable.
After the last freeze I fetched the following error from dmesg (I'm
using a Thinkpad T500):

--------------- 8< --------------------
It really seems I'm out-of-luck with Qubes freezes and, frankly, I feel
a little depressed at the idea I may have to through it away to switch
back to a more traditional Linux distro :'(.
For the record, I already encountered what appears to be the same
freezes with Qubes R2, but setting KWin to use XRender instead of the
OpenGL as the compositing engine definitively solved the issue with no
noticeable drawback and gave me a rock solid Qubes (with full screen
Youtube videos and all the fancy, good old times!).
Since Qubes R3.2 and its switch to XFCE, there is not such option
available anymore. I tried to completely disable compositing from XFCE
settings, it kinda worked by reducing the freezes to about one per month
(which means I encountered 2 or 3 freezes since September, not the ideal
but acceptable), but since a recent update (a rather large one, bringing
a new kernel and xorg packages) now the system is again unusable and
makes me loose my work every 1-2 days.
For the record, my laptop also has an Intel integrated graphic card, it
worked great with Qubes R2 but does not work at all with Qubes R3.2 (the
booting process behaves as normal, but the screen stays black when the X
server should start, setting the Grub option i915.enable_rc6=0 does not
help).
Here is my previous message on the topic:
https://groups.google.com/forum/#!topic/qubes-users/O4UO9CjO4TM
Is there anything I can do or try?
I hope someone has some good news for me...
Thank you by advance for your help on this :) !
Simon.
