Actually, it's probably somehow related to ACL's which are supposed to automatically be append to the device node in question on ConsoleKit activation of the user session: [jclinton@jclinton-laptop ~]$ getfacl /dev/dri/card0 getfacl: Removing leading '/' from absolute path names # file: dev/dri/card0 # owner: root # group: video user::rw- user:jclinton:rw- group::rw- mask::rw- other::--- So, you're probably going to have other permissions related issues until you track down the root cause. The first time I ran in to this historically was plugging my shiny new Nexus One in to my laptop and being unable to come up with a method of running adb against it that didn't involve root access... until I delved in to the interesting intersection of udev and the CK database. Maybe you're missing ACL's support, generally? -- test mailing list test@xxxxxxxxxxxxxxxxxxxxxxx To unsubscribe: https://admin.fedoraproject.org/mailman/listinfo/test
