That's probably because gnome is setting a different modeline when you log in. Check your login settings; I think it should be somewhere in ~/.gnome or similar. You should be able to get gnome to either not set a different mode when you log in or get it to to set the mode you've added.

do you have the same problem with the free nv driver?

if yes you should open a bugreport with ubuntu.

Is there no DVI connector on your card? Usually you can avoid issues like this, and have a sharper pixel-perfect display, by using a DVI cable instead of the VGA cable you are using now.

Good idea. I hadn't tried that.
But... I just changed to the nv driver, and the picture is centered.


And pe1chl... the fx5200 has a dvi connector out, but never got any output from it... the monitor is a dvi-d dual link in, but I have a dvd-d single link cable... and I'm too cheap to spend the $25!

A 1680x1050 monitor should run fine on single link. I have 1920x1200 on single link. That requires 155MHz dotclock which a 5200 usually will not provide.

Well, when you are too cheap for a cable I don't have to suggest that you buy a new card (5600, 6200 or newer low-end card) that does DVI with 155 MHz clock limit.

Nonetheless... the display should still be centered using the d-sub connector, yes? This problem did not occur in Feisty; it is just since I installed Gutsy.

LCDs have autocentering logic for dsub... try throwing a full screen photo up with no black around the edges of the photo, and turn the monitor off and on... [I say this because I had similar issues with Mandrake a few years ago when I had a dsub only lcd monitor.]

I would pursue the remark in comment #13.
I can't tell more about it as I use neither Ubuntu nor Gnome...

OK, I'm feeling like a n00b now... I can't find this anywhere... anyone?
