+++ This bug was initially created as a clone of Bug #545258 +++ hal-0.5.14-1.fc12 seems to induce a couple of bad behaviors in kde that isn't present with hal-0.5.13-9.fc12 1. First attempt to login from kdm seems to fail/crash X, 2nd attempt works 2. kde's brightness controls no longer seem to work, and are now stuck at 0 (dimmest setting). I'm currently focussed on looking at 2. --- Additional comment from rdieter.edu on 2009-12-07 19:45:37 EDT --- $ qdbus --system org.freedesktop.Hal /org/freedesktop/Hal/devices/computer_backlight org.freedesktop.Hal.Device.LaptopPanel.GetBrightness 7 This returns valid values, but $ solid-powermanagement brightness get Brightness is 0% isn't very good. During this, $ solid-powermanagement brightness set continues to work. --- Additional comment from rdieter.edu on 2009-12-07 20:43:20 EDT --- wrt, crash on first login, /var/log/messages contain, Dec 7 19:33:30 localhost kdm: :0[1453]: Cannot open ConsoleKit session: Unable to open session: Launch helper exited with unknown return code 0 Dec 7 19:33:30 localhost kdm: :0[1453]: Client start failed Dec 7 19:33:30 localhost kdm: :0[1453]: Cannot close ConsoleKit session: Unable to close session: no session open weird, re-assigning to kdebase-workspace for further investigation. --- Additional comment from kevin.org on 2009-12-07 23:02:53 EDT --- This doesn't sound like KDM's fault, it's just echoing the error message given by libck-connector. Looks like talking to ConsoleKit is failing for some reason. As for the KDE crash possibly related to no valid brightness, are you using Qt 4.6? See https://bugs.kde.org/show_bug.cgi?id=217805 --- Additional comment from rdieter.edu on 2009-12-07 23:08:01 EDT --- Stock stuff here, qt-4.5.3-9.fc12.x86_64 kdebase-workspace-4.3.3-7.fc12.x86_64 SMParrish was able to reproduce these symptoms @ fudcon too. --- Additional comment from richard on 2009-12-08 03:00:39 EDT --- (In reply to comment #1) > $ qdbus --system org.freedesktop.Hal > /org/freedesktop/Hal/devices/computer_backlight > org.freedesktop.Hal.Device.LaptopPanel.GetBrightness > 7 > > This returns valid values, but > > $ solid-powermanagement brightness get > > Brightness is 0% > > isn't very good. Surely this is a solid failure then? --- Additional comment from kevin.org on 2009-12-08 08:10:27 EDT --- Did something in HAL change incompatibly from 0.5.13 to 0.5.14?
Opened separate bug here to track the libck-connector/kdm failure separately.
Re-assigning to ConsoleKit to get them CC'd for comment.
To be clear, this particular problem only happens on the first attempt to login on a fresh boot, with kdm logging the failure to /var/log/messages, Dec 7 19:33:30 localhost kdm: :0[1453]: Cannot open ConsoleKit session: Unable to open session: Launch helper exited with unknown return code 0 I've up/down-graded between hal-0.5.13-9 and hal-0.5.14-1 several times, with 0.5.13 being fine, 0.5.14 exhibiting this... very reproducible for me.
Interestingly, 2 of us that were experiencing this @ FUDCon, no longer see this since, Dec 18 21:22:59 Updated: ConsoleKit-0.4.1-2.fc12.x86_64 Seems to be a side effect detailed in gdm as well, https://bugzilla.redhat.com/show_bug.cgi?id=545267#c17 *** This bug has been marked as a duplicate of bug 545267 ***
