Version: 4.3.3 (using KDE 4.3.3) Compiler: g++ (Debian 4.3.2-1.1) 4.3.2 x86_64 OS: Linux Installed from: Compiled From Sources Sometimes X11 crash with SIGSEGV after pressing sleep to ram or hdd in PowerDevil applet. This happens more often when Amarok1.4 is playing, than when it is stopped. After it crashed: X restarts and needs to be killed with Ctrl+Alt+Backspace to proceed sleep to ram/hdd.
X.org crashes are caused by bugs within the graphics driver for your videocard. You may wish to report these bugs to Debian and/or X.org, but there's nothing that can be done about them from the KDE side of things. Thanks, and have a nice day.
