Version: (using KDE 4.1.1) OS: Linux Installed from: Ubuntu Packages When I login to KDE 4.1.1 in Ubuntu Intrepid Ibex, I get the splash screen which loads to the end, then I get a white screen with just the cursor. I left the computer for a while (2 hours) then returned, and the screen was black with no cursor. The same bug is seen when I created a new user and logged in as that user.
It was because XRender was enabled. Ubuntu Specific.
