COMMON USER / ROOT GUI

To share the gui environment between user and su (root) so you can run a GUI program such as Kedit from a console after su'ing to get root permissions, insert the following line
xhost +"$hostname"
into the (dot)bashrc file in your home directory.

Or, you can open kedit (or other gui based program) with root permissions from a console by typing;
 [mereuser] su -mc 'kedit'
 password

If you don't want to be locked out of the console while you're running kedit, then
 [mereuser] su -mc 'kedit &'
 password

DUAL GUIS

This allows you to switch between a root gui environment (CTL-ALT-F9) and a user environment (CTL-ALT-F8) (or in fact any two user logins).

Edit /etc/X11/kdm/Xservers so it looks something like;

  :0 local /usr/X11R6/bin/X -dpi 75 -gamma 1.6 :0
  :1 local /usr/X11R6/bin/X -dpi 75 -gamma 1.6 :1

About the -dpi and -gamma options, mine as shown above are part of my war against ugly fonts, the crucial bits are the :n at the beginning _and_ end of each line.

Note from mikea: you might also wish to edit

 /usr/X11R6/lib/X11/xdm/Xservers

and insert the above lines so that both startx and kde achieve the same results.

STARTX

Joseph Van Valen; jrv@vanvalen.com

If you installed w/ LISA, there could be a bug which breaks Xterm.
No Xterm means that the startx script won't start.

To cure it, add the following line to /etc/fstab

devpts /dev/pts devpts gid=5,mode=620 0 0

Init state 3 and DISPLAY :0.0. problem

Bill Campbell; bill@celestial.com

There has been a problem in Caldera that goes back as far as the COL 2.2 beta. The problem comes up when trying to run X from init state 3.
The /usr/lib/X11/xinit/xserverrc file needs one line added to allow access from DISPLAY :0.0.
An example corrected xserverrc file is shown below, the only change is adding the line below the ``done'' line.

 #!/bin/bash
 XAUTH=$HOME/.Xauthority
 MKCOOKIE=/usr/bin/mcookie
 touch $XAUTH
 for host in localhost $HOSTNAME $HOST; do
 xauth add $host/unix:0 . `$MKCOOKIE`
 xauth add $host:0 . `$MKCOOKIE`
 done
 xauth add :0.0 . `$MKCOOKIE`
 exec Xwrapper -auth $XAUTH :0

Runlevel 3 and DISPLAY :0.0 Problem on Caldera eWorkstation 3.1.1

This is the same tip as the above, modified for Caldera's eWorkstation 3.1.1

Jerry McBride mcbrides9@comcast.net

 #!/bin/bash
 XAUTH=$HOME/.Xauthority
 MKCOOKIE=/usr/bin/mcookie
 touch $XAUTH
 for host in localhost $HOSTNAME $HOST; do
 xauth add $host/unix:0 . `$MKCOOKIE`
 xauth add $host:0 . `$MKCOOKIE`
 done
 xauth add :0.0 . `$MKCOOKIE`
 exec X -auth $XAUTH :0

EnergyStar Monitor

From: Les Bell

If you have an EnergyStar compliant monitor, you can modify XF86Config to automatically suspend and power-down the monitor. Here's how:

Su to root

Edit /etc/XF86Config. Scroll down to the section marked: Section "Device". Before the EndSection line, add a line that says:

Option "power_saver"

Now scroll further down, to the section used by your X server: it will be one of the Section "Screen" entries, but which one depends on whether you are using the XF86_SVGA (Driver "SVGA") or one of the accelerated (Driver "accel") servers. You can add these lines to *all* the "Screen" sections, if you want. Before you get to one of the Subsection "Display" entries, add the three lines:

StandbyTime 15
SuspendTime 30
OffTime 45

The times are specified in minutes, and can be adjusted, obviously.

Now, shut down your various X applications and logout, then restart the X server. Your monitor should now power down correctly.
