I am using the REDHAT-3.0.3 linux distribution and my graphics
hardware is as follows:
Bandwidth : -135 MHz
Horizontal sync frequency : 35 - 82 KHz
Vertical sync frequency : 50 -160 Hz
Diamond Stealth 64 Video VRAM video card:
Video memory: 4 megabytes
RAMDAC : IBM RGB-524 (max.220 MHz)
Currently I am running X-windows (XFree-3.1.2) at 1280x1024 and
16 bpp (65536 colors), and the vertical sync frequency is 76 Hz.
That's VERY nice!!!
BUT - here comes my problem:
A few programs don't work at 16 bpp - they require 8 bpp or 24 bpp!!!
Well - 8 bpp is out of the question due to the problems of having too
few colors, so therefore I tried to configure XFree to use 24 bpp
and the same resolution as described above - BUT IT DIDN'T WORK!!!
But when I (occasionally) run Microsoft Windows it is possible to use
24 bpp at 1280x1024 pixels, so the limition is not my video card.
Well - 4 megabytes VRAM ought to be enough to get 24 bpp at 1280x1024.
(1280 x 1024 x 3 bytes < 4 megabytes)
Maybe the problem could be that XFree uses 32 bits per pixel instead
of only 24 bits!!!
Is it possible to configure XFree in a way to use my video card at
1280x1024 pixels AND 24 bpp???
If you have the answer, please e-mail me.
Thanks and regards
