Re: Quantal (12.10) Know bugs and work arounds
RE: Additional Drivers not available in 12.10 install.
When I finally, managed to get 12.10 to install [ after trashing an external HDD with 300Gig of data - separate story!] the default driver for my nvidia GT520 would not support Unity 3D -"not software rendered"; although it ran perfectly well in 12.04.
Though the Greeter login screen did not have an option to run anything else until I installed 'gnome-session-fallback'.
I then found that 'Additional Drivers" is not included in the 12.10 release. Entering that in the 'Dash' search opened a specific version of the Software Center, and ten minutes later it was installed, but not to be found anywhere: not in 'Dash', not in 'System Settings', not in 'Synaptic' [ after installing that too ] and not in a terminal [ 'jockey' would not run saying 'jockey-common' was needed ].
Eventually, I installed the 'nvidia-current-updates' 304.51 with 'Synaptic Package Manager' and removed and reinstalled 'Additional Drivers". I noticed that the 'info' stated "This includes the KDE interface".
So I tried: and "Hey Presto" it worked and 'Additional Drivers" ran, telling me that 'nvidia-current-updates' was installed but not running [ which in fact it was, so that bug is still there!"].
BTW: Contrary to recent Posts here I did not have to install the Linux headers or build essential , i n order to install the nvidia driver.
