Re: [rdesktop-devel] Default Xserver visual, or a better one?

[Peter F. <ps...@lu...>]

Is this an option for you?   If your hardware supports 24 bits, you
you can tell the X server to use 24 bits as the default visual 
instead of 8.  The X command depends on the graphics hardware (e.g.
Creator, Creator 3, Creator 3D, Create elite, etc.) but it's probably
one of these:

  /usr/sbin/ffbconfig -deflinear true

  /usr/sbin/m64config -depth 24

  /usr/sbin/afbconfig -deflinear true


After making this change you'll need to logout and log back in to
restart the X server with the new configuration. 

If the screen appears "washed out" after making this change, you can
try adjusting the gamma correction.  For example, a user has reported
that 

        afbconfig -deflinear true -g 1.1

works well.

Another user reported that none of these commands worked on a SunBlade
100.  However, they were able to get it working by putting this command 
in /etc/dt/config/Xservers:

        :0 Local local_uid@console root /usr/openwin/bin/Xsun :0 -nobanner -dev /dev/fb1 defdepth 24

This hasn't caused any problems for us, and fixes problems with colors
flashing as the mousse is moved between windows.  I've heard that some
older programs may have trouble because they assume that the default
visual is 8 bits.  But, I haven't found any.
