That's odd---I don't have that XAANoOffscreenPixmaps line in my xorg.conf, even after I enabled desktop effects. The effects still work (ie., wobbly windows), but the desktop is so glitchy that it's unusable.
Here's the relevant portion: Section "Device" Identifier "ATI Technologies Inc Radeon R100 QD [Radeon 7200]" Driver "ati" BusID "PCI:1:0:0" EndSection I just added the [ Option "XAANoOffscreenPixmaps" "true" ] under the BusID, and now 3d seems much faster, and the effects are faster too. I wonder why that option isn't added for the r100 automatically? I also tried Beryl, but their window manager doesn't work on this card and reverts back to metacity. Compiz however does now work with all that 3d goodness--except that the desktop goes white, and the bottom gnome -panel with my window list doesn't respond or update.. I tried killing nautilus, because it draws the desktop, but it was still white, even after it came back up. I attached a screen shot of what I mean. You can tell that compiz is working (shadows, alt + tab, all that) but the desktop is white and glitchy and gnome-panel at the bottom isn't working. ** Attachment added: "screenshot of compiz glitchiness on a r100" http://librarian.launchpad.net/7135170/Screenshot.png -- Title bar not drawn on maximized windows when desktop effects are enabled https://bugs.launchpad.net/bugs/89741 You received this bug notification because you are a member of Ubuntu Bugs, which is the bug contact for Ubuntu. -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
