Update: I installed KDE 3.5.6 from kubuntu.org because http://www.kde.org/announcements/changelogs/changelog3_5_5to3_5_6.php says: "Make the connection to ksysguardd more robust."
Now I can get it to work again by doing a killall ksysguardd ( *not* ksysguard ) after resume. -- ksysguardapplet does not reconnect to eth0 after hibernate (suspend2disk/resume) https://launchpad.net/bugs/81732 -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
