I have a similar issue with a Ubuntu Intrepid install on an Acer Aspire One netbook, where gnome-system-monitor plus Xorg consume 60+% CPU, shown both by top and g-s-m.
Running top in maximized gnome-terminal after cold start. CPU usage from Xorg:1-3%, total: 3-5% Starting g-s-m and hiding behind the maximized terminal window: CPU usage slowly creeps up, becoming stable at CPU usage as reported by top of Xorg:~35% and g-s-m:~35%. All other processes combined <3%. Load average by top after ~10min is 0.73/0.78/0.56. Switching to the g-s-m window shows CPU1 and CPU2 each at 30-40%. uname -a: Linux aa1 2.6.27-7-generic #1 SMP Tue Nov 4 19:33:20 UTC 2008 i686 GNU/Linux -- GNOME-system-monitor max's out the CPU, sometimes up to 100% https://bugs.launchpad.net/bugs/292992 You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
