This has been bugging me for a long time now, and my solution had been to stick to the 1.0.x versions which weren't affected by this (at least not for me). Today I finally got around to looking into it and started oprofiling to look for a bottleneck. Oprofile pointed me to the fbBlt() function in libfb.so; and Googling for these terms brought me to this thread: http://lists.freedesktop.org/archives/xorg/2006-March/thread.html#13602 and particularly this message: http://lists.freedesktop.org/archives/xorg/2006-March/013608.html So I just added this line to the "Device" section of my /etc/X11/xorg.conf: Option "AccelMethod" "exa" And restarted X... Firefox is suddenly faster than it's ever been for me :D Unfortunately (as far as I understand), EXA doesn't work for everyone yet, but with my Radeon machines (Mobility M6 LY on my Thinkpad, and RV280 9200 SE on my desktop) seem to be working fine so far with EXA enabled. -- Eric Wong -- To UNSUBSCRIBE, email to [EMAIL PROTECTED] with a subject of "unsubscribe".
