I can confirm this one too, but I can't confirm the X server high CPU usage. But, I do experience the way slow scrolling in f.e. a terminal or Gedit or Geany.

Hmm, I have to correct myself. After some investigation I also experience the high CPU usage of X while scrolling through some stuff. I have opened a 200 line text file in Geany, and when I scroll through it X peaks at 60% CPU usage (Core i5 760). -- Slow performance and high CPU usage on Maverick https://bugs.launchpad.net/bugs/617994 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

I did a bit of digging and found this thread on Nvidia's forums: http://www.nvnews.net/vbulletin/showthread.php?s=6d2356bfbad61b24cdc14c1417a2cb0ft=154563 One poster In particular ran gtkperf which was showing extremely slow performance in font related tests. The poster later claims that It appears to be related to anti-aliasing; if I turn off anti-aliasing the performance problem is gone.

I can confirm this for GTX 285 + maverick beta + binary nvidia driver. Even launching htop causes the Xorg cpu-usage to peak to ~30% on an i7-920. I also noticed some much more serious spikes beyond 100%, which render the system almost unusable (mouse lags, audio playback hangs, etc.). These appear to occur more frequently when utilizing the card's 3d rendering capabilities (i.e. playing sauerbraten in my case). -- Slow performance and high CPU usage on Maverick https://bugs.launchpad.net/bugs/617994 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
