 |
|
Hi all!
Got a strange issue (or maybe not understanding udev  ).
The graphic card is based on SiS chip on a laptop
and everything related to it is compiled into kernel (not modules).
Well here goes; ownership and permissions of /dev/dri/card0
are NOT as defined in /etc/udev/permissions.d/50-udev.permissions !
The defined ownership/permission parameters are dri/*:root:video:0660
while /dev/dri/card0 has following: root.root 660.
Kernel parameters are video=sisfb:mode:1024x768x16,mem:12288.
I have a user in group video but he still cannot access dri!
Any ideas? |

It could be due to PAM.
Check for a <dri> entry in /etc/security/console.perms
(in mine it is commented out) |

I'm having this same problem too. I chgrp'd it by hand for now. hopefully we'll be able to find the real fix.

You do have something like this:
| Code: |
Section "DRI"
Group "video"
Mode 0666
EndSection
|
in your /etc/X11/xorg.conf don't you ? |

Well I think this is something of a legacy workaround.
This works, yes, but why the hell doesn't udev set permissions properly!? |

I don't use udev, but only devfs and I noticed if I manually set the correct permissions, they get reset when X is started.
So perhaps udev does set them correctly... |
