Description Amit Shah 2008-12-17 15:44:01 UTC

Description of problem:
I did a fresh install of F10 via the network, selected only KDE on my ThinkPad X200 laptop. I configured some power saving modes to auto-start screensaver (and lock it) and also suspend the display after some time of inactivity.

When the screen gets locked, I start typing in my password to unlock it but keyboard freezes then. I can use the mouse but can't click on any of the buttons (Switch User, Unlock, Cancel). No keyboard input works, so I can't get rid of X, can't switch to a console, etc.

I can remotely log into the laptop. Killing kblankscreen.kss, etc., doesn't help.

After this happens, the display stays lit and the screensaver doesn't kick in any more.


Version-Release number of selected component (if applicable):
Uses the fedora-updates repo, so KDE 4.1.3

Comment 1 Rex Dieter 2008-12-17 15:48:56 UTC

rpm -q dbus kdebase-workspace
please.

If not at dbus-1.2.4-2, please try updating to see if that helps (may require a reboot),

Comment 2 Amit Shah 2008-12-17 15:57:04 UTC

$ rpm -q dbus kdebase-workspace
dbus-1.2.8-1.fc10.x86_64
kdebase-workspace-4.1.3-7.fc10.x86_64

Comment 3 Rex Dieter 2008-12-17 16:18:26 UTC

Please update to dbus-1.2.4-2, and let us know if that helps or not.

Comment 4 Amit Shah 2008-12-18 14:25:07 UTC

You mean downgrade to dbus-1.2.4?

In the meantime, someone pointed out that compiz and the intel X video driver don't play well and that this is a known bug (I can't find the reference). I've disabled desktop effects and the system seems to work fine. I'll note here if I can provide new information.

Comment 5 Kevin Kofler 2008-12-18 14:29:51 UTC

dbus-1.2.4-2 has Epoch: 1 and thus this is an upgrade to a higher EVR. It was reverted because of the high amount of breakage the 1.2.6 and 1.2.8 versions caused.

Comment 6 Lukáš Tinkl 2008-12-18 15:13:27 UTC

[ltinkl@localhost ~]$ rpm -q dbus kdebase-workspace
dbus-1.2.8-1.fc10.x86_64
kdebase-workspace-4.1.3-7.fc10.x86_64

I have the above and both locking and unlocking works correctly for me

Comment 7 Steven M. Parrish 2009-01-09 21:21:59 UTC

Reporter, have you tried this recently and is it working?

Comment 8 Amit Shah 2009-01-10 05:21:58 UTC

I think it was the desktop effects. After disabling, I've not had any problems.
