[Bug 38131] Re: Firefox causes massive Xorg CPU usage

[Christopher Giroir]

I hate an issue in Debian Lenny that sounds a lot like this, just wanted
to comment that AccelMethod "XAA" in my device section solved it for me.

I was having VERY slow rendering times in Firefox. Switching tabs would
take forever. My computer did not feel like it should.

I'm on a Thinkpad X61s with lspci graphics card line:
00:02.1 Display controller: Intel Corporation Mobile GM965/GL960 Integrated Graphics Controller (rev 0c)

My xorg.conf is largely autoconfigure (except for one Keyboard options
line to replace caps lock with control). I ONLY added the AccelMethod
"XAA" line to my device section to get this:

Section "Device"
        Identifier      "Configured Video Device"
        Option "AccelMethod" "XAA"
EndSection

And suddenly firefox is incredibly fast again. In fact, I didn't notice
this before but ALL GTK apps were slow and they are all faster. I think
this might technically be an xorg auto config problem?

I also think a lot of the problems in this bug report might not be for
the same actual bug.
