Hi,
When I comment these two lines, the gtk-demo starts but the screen
looks very strange (I'd say horizontally squeezed and colors seem
wrong).
I use an nvidia GeForce 8800GT and the nvidiafb driver, but I also had
the same problem in VirtualBox 1.6.0 with the vesa driver. All my
tests were done in Ubuntu 8.04.
What could I do next?
Regards,
Matthieu.
