So i installed ubuntu 12.10 (from cd) and there is no taskbar all the rest works just the bar is missing. My specifications are: amd k8 athlon 64/opteron 2 Ghz
Hope someone can help me with this.
I suggest you to reset Unity.
sudo add-apt-repository ppa:amith/ubuntutools
sudo apt-get update
sudo apt-get install unity-reset
Alternate way:
sudo apt-get install dconf-tools
dconf reset -f /org/compiz/
setsid unity
Hope this helps.
lspci | grep Graphics
in a terminal and edit your question, adding this info.
