I too still have this problem after upgrading to 10.04 :-( I've tried the solution of tweaking /proc/acpi/video/*/DOS, suggested in this related bug: https://bugs.launchpad.net/ubuntu/+source/xserver- xorg-video-intel/+bug/156824
And I've read the upstream bug: https://bugs.freedesktop.org/show_bug.cgi?id=16706 But nothing's fixing it. ** Bug watch added: freedesktop.org Bugzilla #16706 http://bugs.freedesktop.org/show_bug.cgi?id=16706 -- [gm45] closing screen/lid results in flickering and high CPU usage by Xorg https://bugs.launchpad.net/bugs/447803 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
