Configuring Video Mode

You cannot use xrandr to change the resolution because the xrandr function is not supported. You cannot
change the resolution and the number of colors from application menu due to hardware specification. Take the
steps below to change resolution and number of colors.
1. Login with the user having root privilege, and open /etc/X11/xoorg.conf.d/00-ftserver.conf.
2. Modify the following configuration in 00-ftserver.conf.
In the figure below, the resolution is set to 1024x768, refresh rate is set to 70Hz, and the number of
colors is set to 16bpp.
<Changing the numbers of colors>
Change the value indicated by (1) to the number of colors you want (16bpp or 24bpp).
* Use of 8 bpp of RHEL7.2 is not allowed. Do not set it.
Important 00-ftserver.conf is a very important file for the X Window System. It is recommended
to make a backup file because corrupting xorg.conf can result in failure to start up
the X Window System in the worst case. When you make a backup file, use a
different file name for the backup since the file name /etc/X11/xorg.conf.backup is
used by the system.
