After updating and then upgrading ubuntu from 12.04 to 12.10 the following is happening.
Ubuntu will load a black screen initially without any imput cursor flashing or anything, the ubuntu load screen however shows up for a few seconds
Now rebooting from this state brings up the grub loader and after selecting ubuntu 12.10 it takes me to the console, the error:
@wlc_cfg80211_scan wlc_scan error -22
is displayed on the screen repeatadley at intervals
Now after logging in
setsid unity with the warning no display variable set
unity-panel-service: no process found
then compiz will fail -
'couldnt open display'
I tried some other stuff like
startx which gives a fatal error no screen found, im using a dell vostro 1510 with a usb wireless internet connection as well as ethernet
