Hello,

When I booted up the first time today Ubuntu wasn't in
a co-operative
mood. I have my panels set to auto hide and when I tried to
get the top
panel to come out so I could start Thunderbird it would not
slide out. I
tried ALT-F2 to get the run box, and it wouldn't come
up either.

I think you problem lies with compiz or some setting you made with desktop effects, but IMBW. I had the same problem with ALT-F2 using compiz in gutsy until someone told me that compiz doesn't support it or something to that effect and told me to rm compiz. I did and ALT-F2 popped right back up. I'm not sure ALT-F2 is available in compiz. Maybe someone elso does. When I installed intrepid on a new partition, compiz is installed but I don't use it and ALT-F2 still works. You probably can't access the add widgets plasmoid now but it may allow you to get you panels back. I'm using kde4.1 in Intrepid so I don't know if it applies to gnome but expect it does.

So, I tried CTRL-ALT-Backspace to log out and back in, and
this time I
couldn't even see the edge of the top panel which
normally sticks out
ever so slightly when it's hidden. I'm very new to
Ubuntu, [since
August] so I didn't know what else to try. Out of
desperation I tried
the old Windows ALT-CTRL-DEL trick, and after a pause for
15 seconds or
so the normal shutdown dialog appeared, and I clicked the
restart button.

You might try loging in in a failsafe mode from the log in screen and try to fix from there. It would help if you could remember what you changed in compiz just before the issue occured. That you help the experts discover what caused the issue.

I waited quite a while and it didn't shut down, so I
resorted to a hard
power down and restarted in the next previous kernel for
Linux and
things were back to normal.

If you hadn't started using compiz in this kernel or hadn't used desktop effects, then I think compiz is surely your problem. If nothing else works I would purge compiz and start over trying to recall what you did just before the issue came up.

What the heck happened there? I made some changes to the
compiz settings
last night before shutting down, and also changed the
resolution setting
for the boot up screen using the Start up Manager on the
menu.
Changing resolutions can make you desktop not fit on the screen as reported on the list sevral times. Suggest you go back to the resolution you were using before the issue came up to see if that solves your problem. I'd do that even before considering removing compiz.

Do
settings made while booted into one kernel stick when you
boot to a
previous one?

I'm not sure if they are on the same version installed but you results suggest it doesn't. But, I really don't know.

I also want to ask if there is a keyboard command that will
force the
top panel to appear? In Windows when I couldn't get the
menu I could use
CTRL-ESC to force it to appear, but that didn't work
when I tried it in
Ubuntu.

You might try ALT-Tab to cycle through opened files and the desktop.
I don't know if that gets you something you can work with but it wont hurt to try.

Let me know if there is something I need to fix before I
reboot to the
newest kernel again. The newest kernel I have here on Hardy
is
2.6.24-22-generic and I'm currently running in
2.6.24-21-generic.

Thanks for any help you can be. Later, Ray Parrish
