Wonderful. Do you use xinerama?
I cannot get xinerama to work properly with any newish Nvidia driver and
RHEL6.2's X.org, window borders go AWOL.
Weird, I used Xinerama all the time with my GeForce 7300 GT in dual-head
mode, and never had an issue with my borders. Same now that it's the v4900...
No issues at all.
Everything was honky dory for many years and OS releases. RHEL6.2 X.org
required newer Nvidia drivers than I was running and Xinerama simply
refuses to work properly with this combination.
Beer reward for fix :)
