I was trying to report a similar bug when I saw this one. I am having the same problem with the top and bottom panels disappear when I open any application. For example when I open an application, it will always open from the upper left corner covering the top panel. If the application uses full screen, the application will cover both top and bottom panels making them not accessible.
My problem started after I tried to make Firestarter start every time I turn on the computer. The following are steps of what I did and caused the panel problem. After I installed Firestarter using Synaptic, I went to System -> Preference -> Session -> Start-up Session. I clicked on Add New Item. A dialog box opened up. In the command line I typed "Sudo Firestarter --start-hidden" and then "OK". I closed the Session Manager and reboot my computer. I noticed that Firestarter did not start after I re-boot. So I used Session Manager to repeat the add new item several times. I still cannot make Firestarter to start after re-boot. Then I gave up. After the above failed attempts, I opened Firefox. I noticed that the top and bottom panels disappeared behind Firefox. So I tried to open other applications and I found out that the applications always open from the top left corner of the screen. The applications also hide the top and bottom panel. This problem makes using Feisty very inconvenient. Is there a configuration file that tells an application where to open on the screen? Where is this configuration file? Can I manually reset the configuration? -- Top and Bottom Screen Panels Stopped Working Properly in Ubuntu Feisty https://bugs.launchpad.net/bugs/109760 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
