--- Proposed workaround: use Option "AccelMethod" "exa" in device section of your xorg.conf ---- Since installing Dapper Flight 6 last week, I've been plagued by an extremely slow Firefox, though this problem was not present in my previous Dapper install that had, at one point, been Breezy. When running top, I've found that Xorg tends to take up 60%+ of the CPU with the remaining percentage being devoted to Firefox, or sometimes vice versa. This prompted me to edit my xorg.conf. I found that my default config file listed the Device Driver as 'nv' instead of 'nvidia' as it always had been on my machine before I installed Flight 6. Reading advice in https://launchpad.net/distros/ubuntu/+source/firefox/+bug/32561 ( also prompted me to add MOZ_DISABLE_PANGO=1 to /etc/environment. I don't report bugs very often, so I'm not sure on the policy of providing a fix for a problem within the main bug report. :P ** Affects: firefox Importance: Medium Status: New ** Affects: firefox-3.0 (Ubuntu) Importance: Undecided Status: Invalid ** Affects: firefox (Ubuntu) Importance: Medium Assignee: Mozilla Bugs (mozilla-bugs) Status: Triaged ** Tags: amd64 firefox iso-testing mt-eval xorg -- Firefox causes massive Xorg CPU usage https://bugs.launchpad.net/bugs/38131 You received this bug notification because you are a member of Desktop Packages, which is subscribed to firefox in Ubuntu. -- Mailing list: https://launchpad.net/~desktop-packages Post to : desktop-packages@lists.launchpad.net Unsubscribe : https://launchpad.net/~desktop-packages More help : https://help.launchpad.net/ListHelp
