Stan said his Cube has these packages installed: # dpkg --list | grep Xorg ii xserver-xorg-core 2:1.20.11-1 powerpc Xorg X server - core server ii xserver-xorg-legacy 2:1.20.11-1 powerpc setuid root Xorg server wrapper I gather that Riccardo also runs Debian SID. Perhaps there is some interaction between d3ccc9781560, CONFIG_USER_NS and the SUID wrapper... Does your Xorg installation use --enable-suid-wrapper, Andreas?
