I am working on a RHEL 6.3 Workstation. And the monitor is a HD AOC Monitor. Problem I am facing is whenever this machine starts up, it runs with maximum screen resolution. It is a big screen and therefore causing eye-strain while I am working on virtual terminal (accessed by typing ALT+CTRL+(F1-F6)). How can I resolve this issue?

[root@manmatha grub]# uname -a
Linux manmatha 2.6.32-358.2.1.el6.x86_64 #1 SMP Wed Feb 20 12:17:37 EST 2013
x86_64 x86_64 x86_64 GNU/Linux

Alternatively you can use the

or similar commands to install it on your system.

Might try with the vga= kernel parameter


Have you tried xrandr command?

xrandr -s 1024x768
xrandr -s 1600x900

..to whatever you like.

  • xrandr is an interface to RandR, which is an extension to the X Window System.
