Hello all,

I'm having problems with my desktop, as in nothing appears after login apart from the background image. These problems started when I was upgrading to 12.10 and my computer crashed halfway through, so I initially used a terminal to complete the installation, but after I restarted there are still no sidebars.

From searching similar problems, I tried unity --reset, although that now appears to be a deprecated option. Compiz has crashed a few times so I suspect that it's something to do with the problem. I also tried unity --reset-icons just in case, and the output I got is at the end in case it helps.

There's a dark grey bar that appears on the login screen, but once I've logged in this disappears. The same happens if I login using a guest account.

Any help would be greatly appreciated!

Where you using proprietary gfx drivers when you upgraded?

In Quantal use:
reset compiz/unity to default....

dconf reset -f /org/compiz/

Reload unity...

setsid unity

Good question, I'm not sure. Is there a way to find out? My graphics adapter is an ATI Mobility Radeon HD 4670.

dconf reset -f /org/compiz/Reload unity...

setsid unity

Doing this unfortunately gives exactly the same error messages as in the first post.

I had the same problem yesterday. Background but no top panel or launcher. I had to restart my display manager.

sudo service lightdm restart

This brought me out to a tty1 terminal. After logging on (username first) I entered the same code.

sudo service lightdm restart

Now I was brought to a regular login screen and once logged in I had everything back.

Hope this helps.

Thanks for the advice, unfortunately I returned to same blank screen after trying that. :(

Were you using unity/compiz or unity 2d before upgrading.
The error says Unity is not supported by your hardware.
There is no 2d session in 12.10.

What is the output of...

lspci -nnk | grep -iA2 vga

In the mean time you could try to get to a functioning desktop by ctrl+alt+f1.
Login and run...

sudo apt-get install gnome-panel
When the installation has finished enter...

sudo reboot

This will give you a Gnome-Classic(no effects) session you can choose at the login screen.
