Package: x11-common Version: 1:7.7+22 Severity: grave Quack,Since debianutils has dropped the deprecated `tempfile` in 5.0-1 /etc/X11/Xsession fails around the WRITE_TEST and this breaks graphical login completely. Commenting this section allowed me to log in. There is another call line 85 that needs to be changed too.
