I have the same problem, memory leak galore, fglrx in combination with Xorg and the selected window manager.
Ironically the bug seem to trigger memory leaks in Xorg a lot faster when using Gnome classic login (metacity), like 1GB per day, than it does when you login choosing Unity (default), where it leaks roughly 200mb per day for me. In comparison, on another heavily used desktop with Ubuntu 12.04 and nvidia drivers, Xorg allocates roughly 200mb after a month uptime using Gnome classic login (metacity). I guess one of the reasons this bug report is left unassigned, because Unity in general is "leaky", and has been since launch with slowly growing Xorg, so this is expected to some extent. So either use Unity login as workaround, or use classic login (metacity) and watch Xorg leak faster than you can type this command: ps -eo fname,rss | grep Xorg -- You received this bug notification because you are a member of Ubuntu-X, which is subscribed to xorg in Ubuntu. https://bugs.launchpad.net/bugs/1314787 Title: Memory leak To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/xorg/+bug/1314787/+subscriptions _______________________________________________ Mailing list: https://launchpad.net/~ubuntu-x-swat Post to : ubuntu-x-swat@lists.launchpad.net Unsubscribe : https://launchpad.net/~ubuntu-x-swat More help : https://help.launchpad.net/ListHelp
