[ltp] intel GM965 rescales 1024 to 1280 on LVDS on a T61

[U Kuehn]

HI Frederik,

There should be a BIOS option for the display called "HW expansion".
Maybe you have it turned on? Do you get the very initial screens of
GRUB/LILO and the linux kernel before a framebuffer kicks in in full
size, or only a small middle portion of the screen? The former would
hint to enabled hw expansion...

Hope this helps,
Ulrich
