help: hang on X start with PSW500au and s3 virge
Hi Folks,
I have recently aquired an abandoned PWS500au and installed Debian on
it. The existing video card in the machine was horrible: some TGA crap
which only displays colour with 8 bits. So I aquired a second hand
s3virge. This is a 2MB model without the memory expansion chips. This is
running sarge with X4.3. The problem exists with a 2.4.18 or 2.6.8 kernel.
Starting X with this new card invariably causes the whole machine to
hang after the screen flickers for a moment and (sometimes) shows some
horizontal lines. I have tried various options in the config file
(attached below) but it always hangs. I have googled on this quite a bit
to no avail, so I am hoping someone out there has solved this problem
before. As far as I can tell, it *might* be one of two things:
- the "known bugs" part of the s3virge man page
<http://www.xfree86.org/4.4.0/s3virge.4.html> says "The VideoRam generic
driver parameter is presently ignored by the s3virge driver. On PPC this
is reported to cause problems for 2M cards, because they may autodetect
as 4M." Since this is a 2M card, it could be trying to access memory it
doesn't have.
- something to do with bios emulation. I don't know anything about this,
but a few posts from the past have mentioned it.
Any help much appreciated.
Thanks,
Randall.
