Hi fritsch,

Apologies, I have just realised last night's test results using the kernel options suggested are invalid as I had this additional config in a file within /etc/X11/xorg.conf.d/

Code:

Section "Device"
   Identifier "Intel Graphics"
   Driver "intel"
   Option "NoAccel" "True"
EndSection

Have removed the above conf, rebooted and am now re-running the testing with the kernel options you provided.

Will post again with results.
