Re: Black screen problem - need sgfxi help, I think
The nouveau driver is for nvidia video hardware so you definitely don't want to use it with your Radeon HD 4250 on-board graphics.
A couple sgfxi options you might try:
with no options, sgfxi should install the fglrx proprietary driver if one's available for the HD 4250
with the -n
option, sgfxi should autodetect that you are using the HD 4250 and it will install the opensource radeon xorg driver
with the -N radeon
option, it bypasses sgfxi's autodetection and forces sgfxi to install the opensource radeon xorg driver
