I have the same chipset (ATI Radeon 9700, but it is rv350) and I am seeing the same artifacts as you. Thus marking confirmed. There is a similar bug (https://bugs.launchpad.net/ubuntu/+source/compiz/+bug/272969) , though I do not know if it is a duplicate. But there is definitely a workaround that fixes this for me: Option "AccelMethod" "exa" to the device section of /etc/X11/xorg.conf.
Please try if it fixes the issue for you. BTW:if it does not, the quickest way to get rid of the artifacts is to get to another virtual console and then back (alt+ctr+f6, then alt+ctrl+f7). Also, I do not know if it matters that I do have compiz running - I can of course test. I hope I got the assignation and affected package right. If not, please reassign. ** Changed in: xserver-xorg-driver-ati (Ubuntu) Sourcepackagename: None => xserver-xorg-driver-ati Assignee: (unassigned) => Andreas Mendyk (ubuntu-x) Status: New => Confirmed ** Changed in: xserver-xorg-driver-ati (Ubuntu) Assignee: Andreas Mendyk (ubuntu-x) => (unassigned) -- Graphical artifacts present when resuming from sleep. https://bugs.launchpad.net/bugs/293395 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
