2. A: Edit the /etc/inittab file to make it enter run level 5 instead of the default run level of 3. Look for the following line in the inittab file and change the 3 to a 5:
 

id:3:initdefault:

2. A: If you prefer to use the console login screen, and start X with 'startx' then use these options with startx:
 

startx -- -bpp NN where NN can be 16, 24 or 32

3. A: If you are using xdm as your login screen then you need to edit the /etc/X11/xdm/Xservers file and make the entry look like this (for 16 bit color depth):
 

:0 local /usr/X11R6/bin/X -bpp 16

2. A: One of 2 ways:
 

a. More than likely, you have set your system up with more than one resolution (as defined in the "Modes" line in the "Screen sections" of your XF86Config file). To switch to another resolution press the keys Ctrl-Alt-+ (plus key). Hitting this multiple times will scroll you through the various resolutions you have configured.

b. Edit the /etc/X11/XF86Config file and remove all the lines that start with "Virtual" in the Screen section. Then edit the "Mode" line to re-arrange the modes that are available so the highest is first.

2. There are dozens of other window managers available, but we leave these up to you to install and configure, but we don't support them, and we don't recommend that you let anyone else know about them, just to cut down on the "I want to change the color of..." type questions. Having said that, I have used kde, gnome, and xfce.
