"It's alive!"
If you're trying to get X running on an old Paradise 256K card, here's
some info that may help. After the expository text, I do have a
request for help on mice...
Some may remember that I was having trouble getting X running. Well, I
since got my "new" (second hand) hard drive, giving me 100M more room
for Linux. Feeling intrepid -- not to mention liberal with storage --
I went and got the X11 1.1 distribution files (available at all fine
ftp sites), unpacked them in the root directory. I had to relink
/lib/libX11.1.1, but that was straightforward.
The upshot is that the Xconfig I have included at the end of this post
works for my obsolete Paradise 256K SVGA card. Caveats are that the
resolution is terrible (640x400 -- less than half the res. of the
DECstations at work :^) and the aspect ratio is pretty ugly
(squashed). If you have a vertical-size widget on the front of your
monitor, you may want to fiddle with it (mine's on the back, and thus
not practical, since I switch between the console and X a lot). No
complaints, though -- it's great to see X on PeeCee hardware!
My one unhappiness is that I can't get all three buttons on my mouse
to respond... Actually, I have two mice, but I can't get my Logitech
bus mouse working (I have yet to try fiddling with the IRQ jumper) at
all -- on boot, I do see the "bus mouse installed" [sic.] message. I
tried "mknod /dev/mouse c 10 0", but no joy.
The mouse that does work is a Real Cheap(tm) serial mouse, which is
set up as /dev/mouse (symblinked to /dev/ttys1)... but only two of the
three buttons are recognized. The mouse does have a MS (Micro$haft)/PC
switch on it, which is set to MS. Any suggestions on getting either
working with all three buttons?
Without further ado, here's the Xconfig.
