After thinking a little about that line here:
"(EE) intel(0): Failed to set tiling on front buffer: rejected by
kernel"
I remembered that I manually added some proposed lines to my xorg.conf
that I read about in a Howto dealing with that Intel driver performance
loss:
Section "Device"
Identifier "Configured Video Device"
Option "AccelMethod" "uxa"
Option "EXAOptimizeMigration" "true"
Option "MigrationHeuristic" "greedy"
Option "Tiling" "true"
EndSection
I will remove them and see if that changes anything. Anyone else added
some/all of these lines?
