I have the same problem. (with Sidux (Debian Sid Distro), my graphics card is an Intel X3100 (Intel GM965) using xserver-xorg-intel and mesa)
Xorg cpu usage skyrockets while firefox is rendering a page, or while entering text in the addressbar for example. Maybe this is a gtk problem not a firefox problem at all, also I downgraded to an earlier Version of gtk (and libgtk*). Other gtk programs seem to increase xorg cpuload too, but firefox is worst by far. Changing the AccelMethod to eaa or exa didn't work, neither did disabling pango Regards McG aka Roland -- Firefox causes massive Xorg CPU usage https://bugs.launchpad.net/bugs/38131 You received this bug notification because you are a member of Ubuntu Bugs, which is a direct subscriber. -- ubuntu-bugs mailing list [email protected] https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
