HELP:: Cirrus Logic 7543 + X-Windows

Post by Christopher Purv » Sat, 13 Jan 1996 04:00:00



Hi,

I am currently running Xfree Rel. 3.1.2B with 7543 support but having
problems setting up my XF86config to work with the 800x600 screen.

The problem I think may be my 'monitor' section although I am not sure.
Running clmode in DOS the 800x600 works fine at 60Hz.
Further settings of SVGA 800x600 or LCD 800x600 for the display in Win95
both work fine.

Extract from my XF86config.

# 800x600 @ 56 Hz, 35.15 kHz hsync
#ModeLine "800x600"     36     800  824  896 1024   600  601  603  625
# 800x600 @ 60 Hz, 37.8 kHz hsync
#Modeline "800x600"     40     800  840  968 1056   600  601  605  628 +hsync
 +vsync
# 800x600 @ 72 Hz, 48.0 kHz hsync
Modeline "800x600"     50     800  856  976 1040   600  637  643  666 +hsync
 +vsync

Using the first 2 modes brings up the 800x600 ok but is pretty unreadable
lines all over the screen.
Using the third possibility gives a black screen unless.....
Display to tv is disabled in the bios and you press Fn+F5 twice.
According to my notebook manual this puts the computer in both VGA monitor
(if connected) and built in screen mode.
Doing this gives a perfect 800x600 LCD display.

Although this method works it is annoying as hell (excuse language) and so
I would prefer to get one of the first 2 modelines working instead.

I have tried running clmode in dos before starting dos to set up the 7543
but to no avail.

Has anyone any ideas ?

Please email (and post) pur...@cms.cern.ch
I will summerize the replies.

Thanks

1. Compaq, Cirrus Logic 7543 and X-windows, a nightmare without end

Hello,

I have been using FreeBSD on my desktop computer since 2.0.5R and is
more than pleased with it. Naturally I also want to use it on my new
portable, a Compaq 5300 LTE. There was no problem installing 2.2.2R,
except for X-windows.

It has a Cirrus Logic CL-GD7543, which is broken according to the
documentation. If there is anyone out there that has succeeded, I would
happily take part of your wisdom.

I'd appreciate any help in this area.
