<pre>I've found a way to bypass this annoying bug, thanks to the documentation
available at <a href="https://wiki.archlinux.org/index.php/Intel_graphics">https://wiki.archlinux.org/index.php/Intel_graphics</a>
More than a week has passed without suffering the failure, since I implemented
the change suggested there :)
In summary, I created the file /etc/X11/xorg.conf.d/20-intel.conf with this
content (I left some commented lines as a reference to other possible
workarounds that I didn't test):
# content of file begins here
Section "Device"
Identifier "Intel Graphics"
Driver "intel"
Option "AccelMethod" "uxa"
#disabling the GPU usage with the NoAccel option
#Option "NoAccel" "True"
#Alternatively, try to disable the 3D acceleration only with the DRI option
#Option "DRI" "False"
EndSection
# content of file ends here
If you know about another solution or alternate configuration, I would like to
know the details.
Thanks!</pre>
