I got a new Dell Workstation with Red Hat 6.2. I installed VMD and it was
running fantastic as always. But then I had the updates from Red Hat and
installed them. Now, the VMD display does not show up properly. I get the

I read a few of the posts, which sort of conclude to update the graphics
card driver. But if I had that problem, I should not have had VMD working
fine before the Red Hat updates. Any insight will be helpful. I tried
reinstalling VMD as well. Thank you!
