xlib extension randr missing on display "127.0.0.1:1.0"

Hi,

try to start firefox on a SLES11SP4. Get:

xlib extension randr missing on display “127.0.0.1:1.0”

I try to start FF during I am connected via VNC to the SLES11SP4 (Maybe
you need to know this)

I search for anything named randr with zypper but found nothing.

What is to do for using the Browser via VNC?

Bernd

BTW: Same message when using System-Settings from the menu.

Probably this helps:
