udev missing rule to get group video on /dev/dri/card0

[Shiv V]

Binary package hint: udev

Ubuntu Jaunty amd64, udev: 136-4

AFAIK, users belonging to group video used to have access to hardware-accelerated graphics through /dev/dri/card* (user: root, group: video, perm: 0660). As of my latest update, not so. Seems like in the update from udev: 124-12 to udev:136-4, the udev rules were reorganized. The files migrated from /etc/udev/rules.d to /lib/udev/rules.d. Some filenames have changed and some rules have moved. I tracked it down to a udev rule for SUBSYSTEM=="drm" that used to be in /etc/udev/rules.d/40-permissions.rules and is missing in /lib/udev/rules.d/50-udev-default.rules. Was this rule left out intentionally?

Fixed in the upstream udev tree. Thanks!

This bug was fixed in the package udev - 137-1

---------------
udev (137-1) jaunty; urgency=low

  * New upstream release:
    - udevadm test no longer has force option.
    - udevd has --resolve-names=early|late|never option.
    - Group of IDE CD-ROM drives fixed. LP: #315997.
    - Group of DRI subsystem fixed. LP: #317430.
    - /etc/udev/rules.d not existing is not an error. LP: #315780.
    - Bug where device nodes would be replaced by symlinks on rename has been
      fixed. LP: #315979.

  * Use --resolve-names=never in the installer and initramfs, since we don't
    have a useful name service. LP: #319199.
  * Since we don't have to worry about group lookup, we may as well copy the
    default rules into the initramfs as well. This actually double-solves
    LP: #315979.
  * Make sure the root filesystem is writable before attempting to copy
    generated rules across. LP: #224870.
  * Remove /dev/MAKEDEV symlink; the FHS no longer requires it when /dev
    is automatically managed.

  * It is not permitted to call udevadm trigger or settle during an upgrade
    without depending on udev. Attempting this will fail.
  * Change /etc/init.d/udev restart to actually restart the daemon, with a
    bit of detection to print a warning if we missed events while the
    daemon was down.
  * Refreshing /dev is now /etc/init.d/udev refresh-devices
  * Restart udev daemon after upgrade. LP: #317944.

As I commented in bug #188759, there is an upgrade issue here, since the user defined during installation of Intrepid is not member of the "video" group.

Users are not supposed to be members of the "video" group.

The users created in Jaunty are members of "video" by default.

For historical reasons, and we'll be correcting that soon.
