You have been subscribed to a public bug: Executive summary: command line power down works, from KDE it works in about 35% of all cases.
Details: When I go to terminal 1 with CTRL-ALT-F1, log in as root and execute "powerdown now" the computer turns of, including showin immediately a nice Kubuntu logo. This works. When I select "turn off" from KDE the system logs out of X normally, including playing the sound and then the following happens: 20% of all cases: graphical garbage appears on top of screen and after a while a brief flash of the kubuntu logo appears, just before the computer powers down 15% of all cases: kubuntu logo is shown and shutdown proceeds normally 65% of all cases: monitor looses input signal and goes to sleep, computer completely stuck, have to switch off manually by pressing power key for 7 seconds. I seem to remember reading something like this a long time ago in the edgy forums, cannot find it. My feeling is that the Operating system information: Using Kubuntu Feisty, starting from Beta. Problem has always been present, no change Using the ATI (and thus open source Radeon) display driver System information: Asus P4P800 deluxe mainboard Samsung 172T lcd, using DVI input Radeon 9200SE (280) video card I could never shutdown with Edgy, which was the reason I did not install it, and kept with Dapper. I hope that I will be able to shut down with Feisty! ** Affects: kubuntu-default-settings (Ubuntu) Importance: Undecided Status: Confirmed -- Cannot shutdown computer with Kubuntu Feisty https://bugs.launchpad.net/bugs/105102 -- kubuntu-bugs mailing list [EMAIL PROTECTED] https://lists.ubuntu.com/mailman/listinfo/kubuntu-bugs
