1) In addition to the above mentioned CUPS you
may need some additional stuff.
If it is a hp printer you might need HPLIP
(http://hplip.sf.net/)
Brother also has a likewise package. Probably
other manuf. also have their "linux driver"
package.
2) It might be a problem of you video adapter.
That probably tells you videodriver that there a
many modes, where your LCD only supports 2 to 4
of those.
The problem then is that de default chosen
doesn't fit with your LCD.
I think X is used by Suse, so you might try is
and do help
to change video settings. (I don't use Suse so I
wouldn't know, but i had some similar problems
using a desktop , where the laptop never had a
problem.
Kind Regards,
