Please help! I desparately need to run SVGAlib in 1024x768.
I get a picture if I force SVGAlib to use the VESA driver, vgatest gives
me modes up to 800x600, but I NEED a 1024x768 mode.
I've tried, unsuccessfully, to hack the vesa.c code to give me 1024x768
modes but I don't really know what I'm doing.
How can I get *any* 1024x768 mode?
Thanks,
Tim.

I'm using svgalib 1.4.3. I have an NVidia GeForce2 MX graphics card with
32MB of RAM connected to a Digital Flat Panel monitor. The setup works
with X (at 1024x768) and I've added the relevant mode stuff to
/etc/vga/libvga.config:
HorizSync 30.1 50
VertRefresh 58 62
modeline "1024x768" 65 1024 1048 1184 1344 768 771 777 806

If I let SVGAlib autodetect my card it uses the NV3 driver.
Unfortunately the driver has the wrong amount of memory hard coded into
the driver. I got a picture (using vgatest) at 1024x768 but it was off
centre and displayed only in tones of blue and brown.
I updated nv3.c with the amount of memory on my card, recompiled, and now
the picture displays off centre and only in tones of blue (no brown). I
also tried updating nv3.c with some code from the 1.9.12 release, but I'm
still stuck with the same problem.
