I have a Dell Vostro 2420/2520 and when I update the drivers, a green line appears at the top of the screen. Any idea on how to get rid of that?
Also, how do I get my wireless internet to work?
Same here ... brand new Vostro 2420, after installing initial updates and rebooting there are green flashing lines on top of the screen. So something messed up with the graphics driver. No issue when working in text mode or booting of recovery media.
Instead of fixing 11.10 installation, I simply upgraded to 12.10, everything is now working fine.
