[newbie] Anyone gotten 1400x1050 on a Dell Inspiron 7500?

[Don Gafford]

Hi Everyone,

I am trying to run XF86 v4 on my Dell Inspiron 7500. I get 1024x768 and
1280x1024 OK, but I can't seem to use the 1400x1050 resolution. This is a
valid resolution with Redhat 7, so I figured I would just use the modes from
my XF86Config-4 for redhat in my Mandrake XF86Config. No luck. It still
shows that the resolution is invalid and let's me in with 1280x1024. Anyone
struggled through this yet, or know of a place I can look?

Thanks in advance
