gnome-screensaver switch user dialog box buttons don't work after logging out

Oops - here's the image of the box.

This bug occurs to me too, Hardy 32-bit updated.

The workaround is to just press Enter if the button you want to access is Unlock. But to access the other buttons, the workaround is not so intuitive: Tab until you get to the button, and Space.

Still present in Intrepid final.

could you try if that's still an issue in jaunty?

It's still an issue in Jaunty, whether via the Fast User Switch applet or via System/Log out/Switch user, with the same steps.

1. Login as User A
2. Switch user to User B
3. Log out of User B
4. (expected) Type User A's password and click Unlock
   (actual) Type User A's password and press Shift+Tab, Enter or Meta+U, because the Unlock button cannot be clicked

Yes, I can confirm that this bug still exists. It can be challenging to
duplicate. The first Jaunty system I tried worked fine, but following Louis
Simard's steps below (immediately after creating a new user - I don't know
if that's part of it) this bug occured in Jaunty (happens to be Ubuntu
Netbook Remix this time). This system was not upgraded from Intrepid.

Additionally, as I'm testing this, the dialog box with non working buttons
was left on the screen for a minute, and the screen went blank (screensaver
kicked in). After moving the mouse and getting the password prompt again,
the buttons DO work. When I was testing in Hardy, I noted in the
description that the non-functional dialog box did not have the Switch User
button, but right now in Jaunty that isn't the case. The buttons I have are
Leave Message, Switch User, Cancel, and Unlock.

You don't need to have *just* created User B for this bug to show up, any old pair of users on the system that can log into GNOME will trigger it. I tested this on both a fresh Jaunty install (laptop) and a Hardy upgrade (desktop), by the way.

This bug still exists in Karmic alpha 6.

Still present in Karmic after release, with all current updates. Also, in a three-user system, after logging in users A and B, and logging C in and out, user A's locked screen has buttons that work, whereas B's has buttons that don't. After the screensaver kicks in, B's buttons also work.

This still happens in Lucid as of 03/17/2010. Switching to a guest session and logging back out revealed the bug.
