Dual Scan LCD under X 4.0.2

Dual Scan LCD under X 4.0.2

Post by David Goodenoug » Thu, 12 Apr 2001 16:22:32

Back in the days of 3.3.2, there was support for the elderly Western
WD90C24 chip, and its Dual Scan mode.  Apparently later 3.3.x versions
dropped this support.  I have had a couple of systems which needed this
and so I kept them back level.  But now I need to upgrade other bits of
systems, and it is getting hard not to upgrade X as well.  Has anyone
4.0.2/3 to support these beasts?  If not does anyone have any pointers
as to
where the kind of fix introduced into 3.3.x to support them needs to go.

Oddly also although there is explicit support for these chips in
(or at least in its source), SuperProbe never finds them.

1. Linux on Intel STL2 Dual Processor with Intel SC5000 casing and Sony LCD

I am building a linux machine for post-grad project simulation purposes;
dual P3-1GHz processors with 1GB ram, U160 harddisk.

However i'm not sure if i should spend so much money on Intel server boards
and its expensive proprietary casing; SC5000.

Cost of Intel STL2 motherboard: US$600
Cost of Intel SC5000 casing:    US$800

Comparing that with a cheaper MSI or TYAN motherboard and cheaper casing,
does Intel really give that much more stability and performance??

Since I would be running Linux, perhaps getting Intel would be a better idea
since there could be potential drivers-related issues pertaining to machines
with VIA chipset??

Need advice guys...
