It seems that the problem has two parts. The first is wrong owner of /dev/input/uinput: it should be root:plugdev instead of root:root
The second part of the problem can be seen after manually changing the owner: sudo chown root\:plugdev /dev/input/uinput Now after locking the screen you should see 'Password or swipe finger: ' prompt in the unlock dialog but unlocking doesn't work. Swiping finger has no effect and after entering password the dialog hangs saying 'Checking...'. I didn't wait to see if it ever finishes and killed the gnome-screensaver process from console (login didn't offer to swipe finger, only password). I tried reproduce the above with 'gnome-screensaver --debug --no-daemon &> gs.out' and attached the output. Also, I noticed that this is not always reproducible. Sometimes swiping works in the unlock dialog and it hangs only after n-th attempt to lock/unlock the screen. ** Attachment added: "gnome-screensaver --debug --no-daemon &> gs.out" http://launchpadlibrarian.net/19611413/gs.out -- (gutsy) lock screen doesn't support fingerprint readers driven by thinkfinger https://bugs.launchpad.net/bugs/138957 You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
