After upgrading 14.10 to the latest 3.16 kernel today, my Unity GUI is messed up. I was able to create a folder and open it, but if I navigate to the /bin folder, right-click on bash, then select Run, nothing happens. I can't start any program.

Ctrl+Alt+T doesn't work, but I can get to the terminal by pressing Ctrl+Alt+F1. (Thanks to @spqpad for pointing that out!)

I am running this as a VirtualBox 4.3.20 guest. I did have the Guest Extensions for 4.3.18 installed when I upgraded all my packages, including the kernel, with the intent of installing the new Guest Additions after a reboot. I later uninstalled Guest Extensions using ./VBoxLinuxAdditions.run uninstall off the ISO. That didn't change anything. Why was I running 4.3.18 Guest Extensions? I upgraded VirtualBox right before upgrading all my guest OS's packages.

Here is all I see:Unity desktop with no Unity

It might be a compiz issue.
Restarting it with DISPLAY=:0 compiz --replace from tty1 (control-alt-f1) and then switching back to tty7 (control-alt-f7) might help.

  • Thanks. I was able to get to terminal that way, but running DISPLAY=:0 compiz --replace never returns my command prompt. Don't know if that's intentional. If I press Ctrl-Alt-F7 after waiting a while, I have the same screen with no Unity stuff. Nov 25, 2014 at 14:54
