KDE desktop freezes on connection to network
Hi all,
I've recently installed opensuse 11.2 with KDE on a sony vaio z-series, and everything works fine - at home. When I connect it to my work's network (either ethernet or wireless), within about twenty seconds the desktop freezes. If I have any applications open, I can still use them, but I can't open the k-menu or interact with any plasma widgets. If I unplug the ethernet cable everything starts working again after a few minutes (though with some odd graphical behaviour). This is what happens in /var/log/messages: Dec 2 17:02:40 linux-qr96 dhclient: Listening on LPF/eth0/00:1d:ba:69:51:39 Dec 2 17:02:40 linux-qr96 dhclient: Sending on LPF/eth0/00:1d:ba:69:51:39 Dec 2 17:02:40 linux-qr96 dhclient: Sending on Socket/fallback Dec 2 17:02:42 linux-qr96 dhclient: DHCPREQUEST on eth0 to 255.255.255.255 port 67 Dec 2 17:02:44 linux-qr96 dhclient: DHCPREQUEST on eth0 to 255.255.255.255 port 67 Dec 2 17:02:44 linux-qr96 kernel: [ 2692.667996] martian source 255.255.255.255 from 194.131.174.33, on dev eth0 Dec 2 17:02:44 linux-qr96 kernel: [ 2692.668036] ll header: ff:ff:ff:ff:ff:ff:00:30:48:2e:d6:6c:08:00 Dec 2 17:02:44 linux-qr96 dhclient: DHCPACK from 194.131.174.33 Dec 2 17:02:44 linux-qr96 dhclient: bound to 194.131.174.201 -- renewal in 1677 seconds.

I've tried disabling the firewall and turning off the desktop effects (after reading somewhere that this might help) to no avail. Like I said, everything works fine at home - it can connect to the wireless without freezing, so it must be something peculiar to that network. Any help would be greatly appreciated! |
If I were you I would try two things. First of all, at work, kill pulse audio. I see messages from the avahi-daemon, that is part of pulse. I had a nasty bug with pulse. It was killing the wireless adapters, they could not connect to the local WAP with pulse running on my system. Soon as I killed pulse, everything returned to normal. I just disabled it. I can re-enable it at any time, if I want to.
Second, I would install another desktop, and try that. KDE 4 is still flacky, at best. Give xfce a try, it does all the basic stuff well enough. Beyond those two things, there isn't much I can see in the log to give us a clew... |
