System hangs now and then.. using CL-GD 5465

System hangs now and then.. using CL-GD 5465

Post by Mick » Sun, 18 Oct 1998 04:00:00



Recently installed RedHat 5.1, so far so good..
but my card (CL-GD 5465) can't be found in Xconfigurator, so
I have tried both using CL-GD 5464 as well as unlisted card and given it the
specs.
But... if I manage to get X up and running, it eventually crashes and
nothing works.
I suspect it's the problem is with the graphic card, since if I have a shell
open, the last line in it gets garbled.
X always crashes, it's just a matter of time.. it's rather frustrating :p.
Any ideas, comments, anything at all are very welcome!

Thanks

System hangs now and then.. using CL-GD 5465

At last I found someone with the same problem... :^)
I have a "wonderful" Hewlett Packard Vectra VL6/233 Series 7 with the same card,
and it kept crashing every time Xfree 3.3.2 tried a BitBlit operation (at least
I think so...): really a bad crash (control-alt-del ineffective, only power
cycle let me out) reminding me of good old Windows95....     :^)

I solved this by tweaking the file XF86Config. I added the line:
         Option "noaccel"
to the SVGA driver configuration (it is actually already there, you have only to
uncomment it).
Everthing OK now? Yes, but... goodbye to acceleration!!! :^(
I tried also:
         Option "no_bitblt"
this disables only the blitter (less effect on performance) but it didn't work
on my machine: I hope it will solve the problem at least on your PC.
You can find much more options to try in the README.cirrus file.

*** More help request ***
I'm still struggling with another problem: my card has 2 MB of RAM. It works
well at 65K colors at 800x600 and 1024x768 with Windows: I can't make it work
with XFree at the same resolution/color depth.
The best resolution I got is 1024x768 with 256 colors.
If I try to configure it for 65K colors Xconfigurator lets me do it. When I
start X, however, I can't go furhter than 800x600. If I try to switch to
1024x768 I get a garbled screen (looks like it looses the vertical sync, or
tries to interlace...)

I enclose the output from my xinit command for 256 colors and 65K colors... is
anyone able to help me??
Thanks
Rick

1. Cirrus Logic GD 5465 Video card

I am having hard problems with the same setup, but with Debian linux.
seems more an hw/X problem

at random times, mostly when heavily using Netscape or gdm, the system
completely locks up, does not even respond to ping or to the magic SysRq
keys (see kernel docs). Must do hard reboot

problems may have started after switching to 16 bpp

not solved even by Option "noaccel", which makes X very slugghish

a collegue with same setup has no problems using
sw_cursor
xaa_no_color_exp

will try that and report
