Environment

Novell GroupWise 8 Support Pack 2 Hot Patch 2

Situation

Trying to upgrade the GroupWise system through a VNC.
The terminal session locked up with a 'xlib:  extension "RANDR" missing on display "::1:2.0' message.
This also happened when going directly at the server.

Resolution

Run xhost +  as the user before you login as root, then run the ./install.  Root does not have access to a display created by the user by default. That's what the xhost + does.

Also as a workaround, follow the Cool Solution for 'Xming - A X Server for Windows' at https://www.novell.com/coolsolutions/tip/18137.html

Another work around is to enter the following in the terminal session to rub the installation program in text mode:

./install --text

Cause

This problem is caused by an issue with the Linux desktop driver.
