This also happens to me. In fact, the Desktop Effects settings seems to be forgotten as soon as it is set (going back to System | Preferences | Appearance | Desktop Effects always shows "No effects" selected even while Desktop Effects are indeed enabled and working).
Additionally, any time I re-enable Desktop Effects, I receive an error popup with the message "nvidia hardware not available". The message is odd, but correct (I have an ATI card). When I dismiss this message, Desktop Effects get enabled and work smoothly until next reboot (or gdm restart). As I said above, if I close and reopen the System | Preferences | Appearance | Desktop Effects dialog, it again shows "No effects" selected", even though Desktop Effects are still on. After installing CompizConfig Settings Manager, I found that it didn't help with the problem, but the preferences I set through this application are retained when I re-enable Desktop Effects. I upgraded from Feisty manually, because I had the "Current release non found in meta-release file" problem with update-manager -d -- Desktop effects enabling doesn't work after reboot https://bugs.launchpad.net/bugs/127117 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
