12.04 desktop not showing

Asked by Mike Hinchman on 2013-02-26

Ubuntu 12.04 LTS 64-bit system, AMD dual core, was running NVIDIA proprietary 173 driver.
All worked fine for months, then tried to change appearance and colors of menus, then tried to undo my changes. Now no desktop. My fault.

I can get terminal and tried running in safe mode but got fatal error message. How do I reload the UI from terminal? Don't want to lose my data.

Thanks for your help.

Hi ,

you will not lose your data but you will lose ALL the Configurations (even the wallpaper , keyboard layouts .. etc) with the command below

    rm -rf .compiz* .gconf* .config/dconf/ .config/compiz*

Please copy-paste from here . Do not make a mistake.

Above command will reset all the changes you've made and will go the Ubuntu to a primary settings state.

Then you can configure again your program's settings and appearance from scratch.

Hopefully above command will save your installation and will bring your desktop back.

You must reboot for the changes to take effect.

Thank you.

Nik,

I did exactly what you said and copied just the line you gave me to a
terminal, ran it and then rebooted. What happened was that the desktop
background (wallpaper) went to the default and the launcher appeared for
about half a second and disappeared.

Tried it again with same result, so still not working.

What now?

Mike

Try this command

unity --reset

leave it to run for about 1.-2 minutes , and then reboot your system.

Thanks

Hi Nik,

Did not make it through reboot. Had desktop until reboot. After reboot
it went away again. I let the command run for about 15 -20 minutes and
this was the output:

I stopped it at this point and rebooted since you said one to two
minutes was all that was needed.

Any suggestions?

Mike
