Certainly!  I was sorta tired and grumpy when I left last night, I mostly
wanted the moral support of knowing someone else had tried this!  :-)
That aside, I do have specific questions...

I have a Viewsonic P815 monitor.  It's huge, but the boss wanted BIG, so
... what the heck.  It should stomach anything I can send at it, IMHO.
However, I don't seem to have any modelines for 1024x768 that work.  I've
included my XF86Config below for grin's sake.  What happens is 640x480
works, 800x600 won't lock up and I haven't been able to find a 1024x768
tht works at all.  (I had an 800x600 line once that worked, but the
flicker was so bad I was about to get sick...so I pitched that
post-haste.) 

This is on a TP560C.  

SOOOooooOO, bottom line:  anyone have modelines for 800x600 that will work
on both the laptop and the external monitor, and in addition a modeline
for 1024x768 that will not make me sick?

Thanks,

Brian
