I would like to affirm that I am using debian stable versions of gnome and xserver-xorg-input-tslib (0.0.6-5) and when I select System -> Log Out User... Gnome seems to quit, but I end up with a black screen and a mouse cursor rather than returning to the GDM3 log in gui. This does not occur without xserver-xorg-input-tslib installed. I cannot install 0.0.6-6 from testing/unstable because of dependencies. I tried to build 0.0.6-6 from source to add to my debian stable system, but that could not be done either. My touch screen does not require tslib and so I have no use for xserver-xorg-input-tslib except to test for you. If you want to backport 0.6.6-6 to debian stable, I'll test it for you.
