My Menu Bar disappeared

I was messing around trying to switch the dock off and when I did it made my menu bars go, too. I also (stupidly) un-clicked start on login so idk how to get it back. I got lucky and had a file browser open, found terminal so that I could launch firefox, otherwise I'd be staring at a blank desktop still.

I'm running Ubuntu 10 64-bit. I think the dock was called Avant or something, if that's even relevant. Please help, thanks.

Have you tried right clicking on the top bar and choosing add to panel?

No, the bars are what disappeared. And with it all the menus that were on them. I can only find a few useful things through the file system, and I'm a total amateur with Terminal.

gnome-panel

got everything back for me. Except the dock, but I wanted that gone anyway.

Actually, that only works until I close the terminal window, at which point everything disappears again. At least I've got some functionality back though. If someone knows how I can get this to startup on login, I'd appreciate the help. Thanks.

Although its not a complete fix, a workaround may be to add gnome-panel as an autostart program.

System -> Preferences -> Startup Applications
Click Add, and set Command to /usr/bin/gnome-panel

As I say, not a real fix for the original problem, but should make the symptoms go away.

You pay want to reinstall gnome via sudo apt-get install gnome-panel

Thanks for the suggestions. Oddly enough, when I started my computer this morning the menu bar and dock were back. Pretty strange. If it goes all Casper on me again, I'll try one of those.

I have to say, since I updated a few days ago to Ubuntu 10 I've had nothing but problems. I can't get my monitors to configure correctly--keeps telling me to restart the X server. I did, no dice. At least I think I did going by suggestions I found while searching. ctrl+alt+backspace Nothing actually happens when I do it, so idk if that's normal or what.

Plus the performance is really choppy, and at times completely freezes for a few seconds at a time. There's a few other minor bugs as well, but they're all annoying nonetheless.

Mostly because before I updated this computer flew. Now it takes a lot longer to startup, shutdown, ect. Any suggestions as to why this may be, and what I can do to remedy it? Can I just roll back to version 9? Thanks for the help, everyone.

Try using an older kernel version and see if that helps with the performance.
