Version: (using KDE KDE 3.5.7) Installed from: Ubuntu Packages OS: Linux When you set grub as boot manager in KDE options, screen locks after long click on restart. These are the steps to reproduce it in KDE 3.5.7 (Kubuntu): Go to settings manager --> Advanced tab --> login manager. Enter administrator mode In the shutdown tab, go to miscellaneous-->boot manager and then, select 'grub' Normally, on reboot button, you should be able to choose which grub entry will be booted, but with this release, when you 'long-click' on reboot button, the list appears and the screen locks when you choose each grub entry. When screen is locked, press Escape to go out of this menu and then, you are no more able to view the logout menu. This bug is reported in Launchpad at https://bugs.launchpad.net/ubuntu/+source/kdebase/+bug/107642/
works here; i have to conclude that this is an ubuntu issue. try playing with the kdmctl command, specifically: - 'kdmctl listbootoptions' before and after the dialog locks up - 'kdmctl shutdown reboot =<somebootoption> ask'
