Hi all, KDE is no longer working on my system. What happened is, to the best of my memory, (1) yesterday, everything was working fine. I didn't install anything, and shutdown the computer normally (2) today, I forgot to type in my password for /home, which I have mounted with crypto. KDE gets to autologin and fails, saying it's switching HOME to /. This has happened many times before without issue. (3) I do a soft reboot and mount /home. KDE freezes on the splash screen. I can log into GNOME or xfce, and most things work. When I start a KDE application, like dolphin, I get an error, "org.freedesktop.DBus.Error.NoReply". It starts after several minutes. Other applications like Eclipse occasionally freeze (I'm guessing they use dbus less often). I am not subscribed to any factory repositories [1], and the error occurred without any software updates. I tried reinstalling most KDE packages, as well as dbus, without any luck. I'd much like to fix the problem versus reinstalling my system again.

Troubleshooting 101. Try if the problem persists for a new user. If it doesn't - the problem should be hiding somewhere in ~/.kde4/ - and you can consider (re)moving that folder if you don't have much valuable data there. If it does persist for a new user - then your installation would be somehow broken. -- To unsubscribe, e-mail: opensuse-kde+unsubscribe@opensuse.org For additional commands, e-mail: opensuse-kde+help@opensuse.org

Thanks, I did try for root already, and confirmed the problem for a new user. If we can't fix the problem, is there an easy way to reinstall everything? (The kernel, zypper, and yast seem to work fine).

I got the exact same bug on another machine, with separate configuration from my desktop (it's pretty much an internet gateway / dhcpd / dns server)! Hopefully I haven't been hacked... I rather obsessively take all precautions I know of to avoid this... Thanks in advance for any more suggestions.

Hi everyone, I found out what the issue was -- the local loopback / 127.0.0.1 (lo) device was not up. I had removed all of /etc/sysconfig/network/ifcfg* because YaST's LAN module wasn't letting me delete some old devices. More details on this thread (it happened to mess up BIND / named as well): https://lists.isc.org/pipermail/bind-users/2010-January/078604.html . Sorry to send so much email over a non-issue, and I hope this helps someone in the future (from google search of org.freedesktop.DBus.Error.NoReply). Thanks very much, Nicholas — ntung at ntung — https://ntung.com On Sun, Jan 24, 2010 at 6:43 PM, Nicholas Tung wrote:
