/dev/event* produces no output for any devices

[Daniel G. Taylor]

Binary package hint: linux-image

Running cat on any of the event device interfaces in Intrepid produces no output. It worked fine in the release before. This functionality is used by several programs, including a key status monitoring program I wrote and many of my users are complaining about it now producing no output. The program is available here but just using cat should work to test:

Thanks.

This is due to the way that the evdev xorg driver works I think. You can monitor them if you stop Xorg. Not sure if it is considered a bug though

and is fixed in jaunty, needs xserver 1.6 & evdev 2.1.

[Daniel G. Taylor (danielgtaylor)]

Thanks for the quick reply. I see you set the bug to fix released however jaunty is not yet released... what am I supposed to tell users of the software that are having issues? Is it possible to backport the fix for intrepid?

[Timo Aaltonen (tjaalton)]

don't use evdev; set 'Option "AutoAddDevices" "false"' in the ServerFlags section.

Timo, your fix, together with a manual setting on Dan's code did the trick for me. Thanks.
