I recently encountered an interesting problem while installing
'X' windows version 1.1.1 under 386ix 2.0.2.  The installation went
smoothly and a new kernel was built and installed with no difficulty.
When 'X' is started up from any virtual terminal, ie: console, vt01 etc..
'X' starts up with no problem.  If I switch to another virtual terminal
I can see the cursor but nothing else, ie: any characters that I type
are invisible.  I can switch back to the 'X' window and everything
looks fine.  When I leave 'X' my initial virtual terminal goes into this
state as well which is a problem because the only way to fix the problem
is to reboot the machine.  This is difficult when you cannot see what
you are typing.

This only happens when a mono VGA monitor is used.  My work around
is to boot the system with a color VGA monitor attached and after the
system is up in level 2 or 3 I replace the monitor with the mono one.
The mono one works fine with this work around.  You may be interested to
know that the color monitor does appear in color so the driver really
does think that it is color.  The hardware is a Compaq 386/20E with
a builtin VGA mono/color controller.  'X' works fine under 386ix 1.0.6
so I presume that something has changed under 2.0.2.

Has anybody seen this problem?  Could it be related to my 'X' configuration?

My Xconfig is as follows:

#	386/ix X Window System Configuration file
#ident	@(#)Xconfig	1.10 - 89/09/28

# RESOURCE	TYPE	INFO		NUMBER	DEVICE
#dev type	manuf	extra		dpy.scr	device		# comment
keyboard	AT	101		0	/dev/console:/dev/vt%02d
mouse		LOGI-B	3		0	/dev/logi
display		VGA	"640x480 16 10x7" 0	/dev/console

Please mail any suggestions to me.
