There is a program in Synaptic called do-vesa.
You can run it from the console as root (or terminal). It
will put your video card setting to vesa. Then
reboot. It should eliminate or confirm that the video
card is the culprit, if vesa works fine thru the boot
You said you can get into the system after using Windows,
Hmm, that script do-vesa IS installed.
Going to remove it and see if that makes any difference.
I meant you should run the script and reboot.
To change back to your regular video driver
use the PCC Control Center. Easy test.
That won't help indicate..... ANY re
boot (also from xxuntu) simply works...
It is just "cold boots", into any of the Linux installed, that fails.
My best guess is now there simply is a so far unresolved driver failure (ATI/AMD stuff). What else?
I removed the bfs kernel and use now the standard kernel (thought behind that was maybe bfs is in too much hurry).
But nothing changed.
In xxbuntu I found a ATI/AMD related driver named xvba-va-driver. Installed the same. Still the same.
The DeBaas option becomes my very last option now....
Going for it.
Otherwise we got to live with this inconvenience. Laptop is new and has to serve us for a while.
