Hi,
I'm using ubuntu on a z21 with a GS9300m gfx card. For some time now, 
I've been able to switch between Intel and Nvidia, using the stamina - 
speed button and the only thing I've done is set the "acpi_osi=" in the 
grub boot loader.

Today I just upgraded to kernel version 3.2.0-25 (from 3.2.0-24) and 
suddenly I get the infamous colorfull lines on the screen, when trying 
to boot with the Nvidia card (before, they only came on boot, but 
dissapeared when the ubuntu login screen appeared). Any one got a clue 
as to what is causing it?

If I choose to boot from previous kernels (3.2.0-24), from the grub 
menu, everything works just fine.
