Dell D800 screen settings in Linux

[maslett]

Hi, I just installed Mandrake 9.2 on my Dell D800 and have 2 problems regarding X-windows:

1. I can't find the right monitor/resolution settings to utilise the widescreen. I don't know if I need new drivers or if there is an existing setting I can use.

2.When I exit x-windows my display goes belly up with squiggly lines everywhere and I can't read any text. If I type 'startx' x-windows starts again and I can shut the laptop down from there but it irks me that I can't start and stop x-windows when I want (I'm a bit of a command line affectionado)

Thanks in advance,
Matt
