I have a fairly large problem with one of my desktops at the office. It has an AGP nVidia 7600GS 512MB video card in it. We just wiped it out and put on Wheezy with KDE. I built the "nvidia-kernel-source" package and installed it along with "nvidia-glx" and "nvidia-xconfig". Currently the xorg.conf file contains only the section to load the nvidia driver.
Upon a fresh reboot, one user can login and get full hardware acceleration/compositing. If this user logs out and the same user or any user logs back in, KDE hangs at the login screen with the fourth icon fading in. I have to use pkill to kill the user, restart kdm, and then somebody can login again. I did not have this issue on Squeeze.
Now, I am debating using the official driver, but would prefer not to. What should I do at this point?
