Hi @ll,
- I'm trying to test different screen savers to see which one I like best. There seems to be some savers which change screen resolution. Preview of this savers in the screen saver dialog box works fine but as soon as I say "Test" the system badly crashes: First the screen blackens (I suppose it's switching screen res), then it switches back to the old res, then X seems to start again and shortly after that mouse and keyboard freeze without a logonscreen, resulting in a dirty shutdown by having to use reset. If I'm fast enough and I manage to switch to a console during the restart of X I can try to log into a console but the shell isn't starting up.
Did you try <Ctrl>+<Alt>-<Backspace> to kill X? What's in the logs? Can you login remotely with another PC? If you can, run 'top' prior to testing to see if there is a process going mad (using 100% CPU or memory).
After login I can type characters after characters without ever seeing a prompt. Even Ctrl-Alt-Del is broken.
Edit /etc/sysconfig/sysctl, set ENABLE_SYSRQ="yes" Run SuSEconfig, and reboot. This enables the kernel's "magic key" sequences, see /usr/src/linux/Documentation/sysrq.txt In short: if <Ctrl>+<Alt>-<Del> does not work, you /may/ have now a last resort: Press these sequences in the same order: <Alt>+<SysRq>-<S> ==> S)yncs the disks <Alt>+<SysRq>-<U> ==> U)nmounts the disks <Alt>+<SysRq>-<B> ==> reB)oots (release all keys between sequences) [Germans call <Ctrl>+<Alt>-<Del> 'Affengriffe' (monkeygrip/grab). I wonder how they would call those <SysRq> combinations... ;) ] The SysRq combinations do not always work, but it is best to try them instead of relying on the recovery mechanisms of e.g. the Reiser or Ext3 filesystems.
It says it is initiating a shutdown but the system never ever goes down for reboot. Again knock reset before knocking my head on the wall...
