However, an event is only fired once and then never again.

Mai 2012 uevent Note the modification date of status and the other files. That of status did not change at all since boot, and the mdates of the others did change once apparently. I can poll "status" and see the changes when executing xrandr, but there will be no more events, and the modification dates do not change anymore. -- Configure bugmail: https://bugs.freedesktop.org/userprefs.cgi?tab=email ------- You are receiving this mail because: ------- You are the assignee for the bug. _______________________________________________ dri-devel mailing list dri-devel@xxxxxxxxxxxxxxxxxxxxx http://lists.freedesktop.org/mailman/listinfo/dri-devel
