Ubuntu 12.10 no network and no graphics
- by khasiKoMasu
I recently upgraded Ubuntu 12.04 to 12.10 only to find out that it won't connect to any network, neither wired nor wireless and the graphics is messed up too as in a low screen resolution.
For 12.04, my system was running perfectly. I don't know why upgrade messed it up so bad. Reinstalling the OS is an issue because I have set up a lot of development environments that I cannot afford to set it up again.
Some of the outputs:
