Ximtool CDE

misselt@dirty.phys.lsu.edu wrote on Apr 20, 2000

Hello - I have the well known problem of not being able to 
start ximtool because my default X visual is not 8 bit 
PseudoColor.  My default visual is: 

    visual id:    0x28
    class:    TrueColor
    depth:    24 planes
    available colormap entries:    256 per subfield
    red, green, blue masks:    0xff, 0xff00, 0xff0000
    significant bits in color specification:    8 bits

I'm running CDE 1.3 on an Ultra60 with a Creator3D graphics
card.  I would like to be able to start a windows session from 
the CDE login screen and be able to use ximtool.  However I 
haven't been able to figure out how to start CDE in 8 bit 
PseudoColor.  I have access to other machines where this is
not a problem, but I'd like to be able to iraf normally without
switching offices :)  Any suggestions on configuring CDE to
default to pseudocolor appreciated! Thanks,
-Karl

	You can change the system default by editing the system
/usr/dt/config/Xservers file to add the arguments 

        ........ defDepth 8 defClass PseudoColor

Or, on the command line start X using something like

        /usr/openwin/bin/Xsun :0 -dev /dev/fb defclass PseudoColor

Note that you can put the above command in a .xserverrc file in your login
directory (see the xinit man page) and just comment it out when you want to
restart in 24-bit mode.
	Hope this helps.

Cheers,
-Mike

By default Creator3D is a 24-bit plus 8-bit overlay graphics 
system.  This means that if you don't change any of the factory
settings for the framebuffer or CDE, then ximtool will run just 
fine because there is already an 8-bit display running 
simultaneously on top of the 24-bit display.  So, you must have
intentionally set the system to run in 24-bit only mode; change 
it back.

I have several Ultra boxes with Creator3D.  Ximtool runs with
no problems in the default 24-bit plus 8-bit overlay mode.

Hi Craig - I 'inherited' this machine about 6 months after it came
out of the box; I have not reason to suspect that the person who 
originally set it up changed any of the factory defaults, but 
apparently something like that was done.  How can I check this, i.e. 
where would such a change be made?  Thanks,

Hi Mike - Thanks for the info...

I've had an .xserverrc setup for some time.  I can go to the console
login and start openwin manually and I can run ximtool fine.  What 
I'd like to be able to do is start from the CDE login screen (the xserver
is already running) and run ximtool from my normal cde session.  I
tried the modification of the /usr/dt/config/Xservers, i.e. the original 
file looked like:

  :0   Local local_uid@console root /usr/openwin/bin/Xsun :0 -nobanner 
-dev /dev/ffb0 defdepth 24

which I changed to 

  :0   Local local_uid@console root /usr/openwin/bin/Xsun :0 -nobanner 
-dev /dev/ffb0 defdepth 8 defClass PseudoColor

However, when I do this I get an error: 'Cannot open console :0' - I'm 
not sure if this is the exact error message - I didn't log it and I'd 
have to kill this message to verify it... The upshot is that the cde 
login screen doesn't come up when I make the change to Xservers.
