Hello, 

I luckily found the alp_driver.c at the following url: 
http://wuarchive.wustl.edu/mirrors/NetBSD/NetBSD-current/xsrc/xfree/xc/programs/Xserver/hw/xfree86/drivers/cirrus/alp_driver.c
 this file has the following date in the header: 2004/01/04 
I read at line 714 of this file that : 

...
"No valid MMIO address in PCI config space\n");
/* 5446 rev A do not use a separate MMIO segment */
/* We do not really need that YET. */
...

This the message I get when I start an X session, see below a
part of my /var/log/XFree86.0.log file. And a few lines below
of the alp_driver.c file :

#if 0
	/* Will we ever support MMIO on 5446A or older? */
	if (xf86ReturnOptValBool(pCir->Options, OPTION_MMIO, FALSE)) {
		pCir->UseMMIO = TRUE;
		from = X_CONFIG;
	}
#endif


And I have this old graphic card, and I guess the Vesion of my
card is 0: 

# lspci -v 
00:05.0 VGA compatible controller: Cirrus Logic GD 5446
(prog-if 00 [VGA])
        Flags: medium devsel
        Memory at ef000000 (32-bit, prefetchable) [size=16M]
        Expansion ROM at ffaf0000 [disabled] [size=32K]
 

Did I find my problem ? Can this problem be relied to display
problems on my old 14" proview monitor ? There are bad
"horizontal vibrations" on the screen, during X sessions, and
this is the main problem. The prompt when I type text may have
some strange colors. I used another windows system without
this problem.


Does a newer version exists ? I use XFree86, Version 4.3.0.
Otherwise, would it be difficult to solve this problem ??


Cheers, xavier droubay.

PS : I use 800x600 resolution with 8 depth.
