Configuring The Video Mode - NEC Express5800/R320a-E4 User Manual

Configuring the video mode

This section describes how to configure the video mode for this device.
1. Open /etc/X11/xorg.conf as a root user by using an editor.
IMPORTANT:
xorg.conf is a very important file for the X server system. It is recommended to
create a backup because corrupting xorg.conf can result in failure to start up the
X server in the worst case scenario. When you make a backup, use a different
file name for the backup since the file name /etc/X11/xorg.conf.backup is used
by the system.
2. Modify the following configuration in xorg.conf.
Enter the value you want to configure in (1)'s ModeLine in the (2)'s Modes line.
Changing the numbers of colors
Change the value indicated by (3) to the number of colors you want (8bpp, 16bpp or 24bpp).
If you have chosen 24bpp, delete # at the top of the line indicated by (4). (If you have chosen
8bpp or 16bpp, make sure the line starts with #. If there is no #, enter it.)
3. If the X server is started, shut down the server by entering 'init 3' in a command line.
4. The mode is switched to the console mode (CUI), and then, start up the X server by entering 'init
5' in a command line.
