** Description changed: Binary package hint: xdm Bug discovered after upgrading an xdm-using 8.04.2 LTS x86_64-desktop laptop to 10.04 LTS, but now repeated as follows. Take default gdm-using 10.04 LTS x86_64-desktop laptop aptitude install xdm and set xdm as the default window manager restart You will now see the ubuntu white/red dots animation, and that's as far as things go. ctrl-alt f1 gets you a log in prompt ps ax | grep dm shows nothing - so this isn't the same as the "both gdm and xdm run" bug. In fact ps ax | grep -i x returns nothing. Extras: x.org x server v 1.7.6, intel graphics controller. According to kern.log fb0: inteldrmfb frame buffer device ... drm Initialized i915 vga16fb: not registering due to another framebuffer present so things should be set for X to start, namely drm Initialized looks hopeful Yet running xdm -debug 2 from vt1 shows ... /usr/bin/X :0 vt7 -nolisten tcp -auth /var/lib/xdm/authdir/authfiles/... (all OK) ... (EE) intel(0): [drm] failed to set drm interface version. Failed to become DRM master. failed to get resources: Bad file descriptor Kernel modesetting setup failed (EE) Screen(s) found, but none have a useable configuration. Also surprising as: drmOpenDevice: node name is /dev/dri/card0 open result is 9 (OK) (Chipset GM45) So, how come X thinks drm isn't setup, yet the kernel thinks it is? Work around: put gdm back as default with dpkg-reconfigure {gdm|xdm} Now comparing Xorg.0.log in broken xdm and working gdm cases, xdm has: xf86OpenConsole: setpgid failed: Operation not permitted xf86OpenConsole: setsid failed: Operation not permitted and later drmOpenByBusid returns nothing as opposed to pci:0000:00:02.0 So, why the permission denied? apparmor not treating xdm as well as it treats gdm? (no ubuntu-bug -p xdm included, as I am writing this on a working single-boot NetBSD/i386 laptop) + --- + Architecture: amd64 + DistroRelease: Ubuntu 10.04 + Package: xdm 1:1.1.8-6ubuntu2 + PackageArchitecture: amd64 + ProcEnviron: + LANGUAGE=en_GB:en + LANG=en_GB.UTF-8 + SHELL=/bin/bash + ProcVersionSignature: Ubuntu 2.6.32-22.33-generic 2.6.32.11+drm33.2 + Tags: lucid + Uname: Linux 2.6.32-22-generic x86_64 + UserGroups: adm admin cdrom dialout lpadmin plugdev sambashare ** Attachment added: "Dependencies.txt" http://launchpadlibrarian.net/49203672/Dependencies.txt -- [Lucid] Not possible to use xdm, only can use gdm https://bugs.launchpad.net/bugs/585853 You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
