Package: xserver-xorg-core Version: 2:1.4-2 Severity: important Hi, If I try to use an alternate configuration file the X server refuses to start: $ X -xf86config xorg.conf.test
Fatal server error: Cannot open log file "/var/log/Xorg.0.log" xorg.conf.test is in /etc/X11/ This used to work before the 7.3/1.4 upgrade. With those versions, -config wouldn't work, but -xf86config was ok. Looking at the X debian wrapper (in x11-common) it seems that if -config or -xf86config are found in the command line root priviledges are automatically dropped. if (!strcmp(argv[i], "-config") || !strcmp(argv[i], "-xf86config")) { if (setuid(getuid())) { perror("X unable to drop setuid privileges for alternate config"); exit(1); } } As a result, the X server won't start at all. Is this behavior really necessary? The Xorg server will not let non-root users use configuration files outside /etc/X11 which seems to be a good enough safeguard. A google search found that Ubuntu has a patch addressing this issue: https://lists.ubuntu.com/archives/ubuntu-patches/2007-August/011669.html "Stop handling -config specifically in the wrapper, as Xorg now handles this itself." Would it be possible to apply something like this to Debian?
