I had been using my CompuAdd generic VGA card with my generic Samtron
640x480 VGA monitor with success using X386mono. But I decided to take
the card out and noted that it was a PVGA1A, which is supported by
X386.
To make a long story short, I finally got it to work using the modeDB
values from the Xconfig.mono file except for one irratating problem:
windows wrap on my screen where they shouldn't. In other words, if I
have an xterm in the middle of the screen, there will be a copy of the
bottom half of the window at the top of my screen, and corners of the
window is scattered about in various places also. An xclock window in my
upper right corner will put a duplicate somewhere at the bottom of the
screen. There's definitely some confusion here.
Upon further investigation, I discovered I had a VGA card with only
256K of RAM, but my Xconfig was forcing it to 512K. Ah ha! I thought,
that's the problem. But when I changed the memory size to 256 in
Xconfig, startx failed saying not enough memory for the resolution. I
tried changing the resolution to 640x400 (which by my calculations
should only need 250K) but still the same thing happens. I even tried
absurdedly low resolutions like 300x200 just to get past the low memory
error, but nothing worked.
Anybody got any ideas? I so wish to have color.
thanks
john
