I'm having this, too, with the only exception being that Xorg seems to hog resources when I'm running Firefox whether I'm using desktop (Compiz Fusion) effects or not (Kwin).
To a lesser degree I get a similar thing in Opera, but only a fraction as much as FF. My System is as Follows: - Kubuntu Gutsy 32 bit (fully updated every day) - Nvidia 8600 GT card (with driver installed from Restricted Manager) - 3.2 gHz Intel processor - 4 gig ram - Firefox 2.0.0.6+2-0ubuntu4 - Compiz 1:0.5.2+git20070918-0ubuntu5 - emerald 0.3~git20070717-0ubuntu1 There's also a post on ubuntuforums here: http://ubuntuforums.org/showthread.php?t=559774 It seems to me that in some strange way this bug might be linked to: https://bugs.launchpad.net/ubuntu/+source/strigi/+bug/128876 As the amount of CPU my Xorg uses, drops dramatically when I close either Firefox OR strigi-daemon. But then maybe it's just that my systems decent enough to not choke with this bug alone, but combine the two and BAM! -- firefox and xgl cause 100% CPU https://bugs.launchpad.net/bugs/145696 You received this bug notification because you are a member of Ubuntu Bugs, which is the bug contact for Ubuntu. -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
