I've seen that as well, when that happens (in the unity greeter there) clicking on the users doesn't work either, keyboard navigation is still working though

[Michael Terry (mterry)]

I believe it's easiest (only?) triggerable when clicking on the edges of the screen. I'll look into this a bit, but it's a weird one.

Still the case with
lightdm:
  Installed: 0.9.3-0ubuntu8
  Candidate: 0.9.3-0ubuntu8
  Version table:
 *** 0.9.3-0ubuntu8 0
        500 http://archive.ubuntu.com/ubuntu/ oneiric/main amd64 Packages
        100 /var/lib/dpkg/status

Left click is ok and displays drop-down menus.
Right click on empty space locks indicators (which btw. look well integrated now).
Then a click on the button to view available sessions also doesn't work.
Mouse click to bring pwd field into keyboard focus works and allows to login.

is somebody still getting that issue? it seems to work fine there with the current version

[Bryan Paddock (bryanpaddock)]

Yes, I downloaded the daily build yesterday (sep 29th 2010) and I have the same problem.

Updated today with latest updates and problem still persists.

Cant click at all anywhere once clicking once on the titlebar.

I suppose is the same bug.. In the lightdm login screen my mouse click dont work sometimes.
I cannot select session or click on the top bar. If i put the cursor on the little icon to select session, icon don't change, no reaction.. i can just login with the previous session that i selected the last time, cannot reboot, cannot shutdown..

It work again if i logon into a session and disconnect..

[Sam_ (and-sam)]

No issue here anymore with right click on indicators, afterwards menus open, shutdown can open a dialog window (although it looks ugly, like gtk2), calendar displays ok.

Idea due to Bug #828761 and since #9 doesn't have the issue anymore with open source radeon driver, could it be related with nvidia?

This bug also affects me.
Hardware : notebook Asus Eeepc 1005PE

The mouse clicks are disabled if I click just once in the upper bar of the login screen.

They are *not* disabled if I click on the icons on the upper right (battery, date, speaker, ...)

Restarting the lightdm service in a terminal (ctrl-alt-f1, then login, then sudo service lightdm restart) makes the mouse clicks respond again.

Note also that no sound is produced on the lightdm login screen, as opposed to when I start gdm

[Sean Davis (bluesabre)]

This should be fixed in the latest versions of the lightdm-gtk-greeter. Please test this again.
