[newbie] screen resolution

[cedric]

Installed MDK 7.2 -- love it.
Can't get screen resolution right.
Tried to change with, DrakConf, Screen Resolution, with no luck.
Also, xf86config, no luck.

Which file is 'startkde' located in?
I should be able to do:
startkde -- -bpp -16.


Any help appreciated.
