The framerate has dropped dramatically. I can no longer view full-screen flash video. Compiz no longer works - I've had to resort to using metacity compositing. On boot, plymouth is low resolution, with the old Karmic double black-graphics flash when moving from plymouth to the GDM.
Having said all that, graphics seem rock-solid without any graphical glitches and panel refresh issues with the 2.6.35-rc6 "ppa:brian-rogers/graphics-fixes" kernel.
I tried adding i915.modeset=1 to the grub boot option. However, whilst this fixed the low resolution plymouth, the GDM was never displayed - just a black-screen. I tried with both i915.modeset=1 and without the "shadow" = "true" in xorg.conf. This resulted in the infamous GLib-WARNING **: getpwuid_r(): failed due to unknown user id (0) issue.
I also tried without i915.modeset=1 and without "shadow"="true". To be honest, the only difference that I observed was that the framerate with full screen graphics was slightly faster, but still unwatchable.
On a separate issue - before testing the new ppa, I cant use the 2.6.35-v9patch1-generic "ppa:brian-rogers/graphics-fixes" kernel since the mouse cursor is not displayed. On this issue, this new kernel for me has regressed since the rc-6 kernel that had the incoherency fix.
Just a few observations with the new ppa.
