Using a Screen Resolution of 1024 x 768 in a Red Hat Enterprise Linux 5 Virtual Machine

Details

When using VMware ESX Server, after installing Red Hat Enterprise Linux (RHEL) 5 on a virtual machine, even if a screen resolution of 1024 x 768 is selected, the virtual machine boots with a resolution of 640 x 480. This occurs even when VMware Tools is installed and the guest operating system is rebooted.

Solution

This is a known issue. Work around the issue by manually selecting a screen resolution of 1024 x 768, either by using RedHat's configuration tool or by directly editing xorg.conf.
 
To use the RedHat configuration tool, execute system-config-display and choose 1024x768 from the drop down menu in the user interface.

To edit the Xorg configuration file manually, open /etc/X11/xorg.conf and make sure that the 1024x768 mode is included in the Screen section as shown below.
