Description:
After standard installation as Workstation with X-environment all goes well,
although sometimes the installation procedure does not finish nicely, so manual
reboot/reset needed to boot into Linux.
After booting into Linux X-environment/server the loginscreen appears (whether
with Gnome/KDE/Xfree desktop); when logon as root the spontaneous reboot occurs
almost directly at typing in the second alphabetical sign of the password.
When logon as a regular user the logon sequence runs properly most of the times
(sometimes the reboot at the same instance as the root logon) and X-desktop appears;
moving around seems to run okay until moving around a window or going into the
choice to look at the LiLo settings (sometimes directly when trying to open the "Expert"
-Tab) - when reboot did not take place, logging out of the desktop login almost certainly
causes a system reboot.
Note: this is NOT a shutdown with reboot, but a HARD system reboot, causing
disrupted filesystems, since they have not been properly shut down!
I tried many things, like installation as a server without KDE or Gnome and X-environment
absence at all, which seems to run okay as long as I stay in runlevel 3 - moving to runlevel
5 by modifying the "initdefault" setting or by hand causes the problems as aforementioned.
Also upgraded Flash-BIOS to highest revision level (A07) and tried setting changes of all
kinds, but that resulted mainly in significant slow-down of system performance (even tried
to disable the memory cache ....) - everything failed. I even tried (please forgive me, but a
desperate person can do funny things) installation MS Win NT4.0 server, which went all
well without ANY problem, so I think the problem is not in the hardware, but most likely
in the software. Even with my background knowledge of several Unix versions like
BOS-UX(Bull Unix), SCO-Unix, XENIX, ESIX, SINIX, MINIX, Digital Unix, Interactive Unix,
AT&T Unix and HP-UX, I could not think of a workable solution for this problem.
Assistance:
Has anyone encountered similar problems and how can this be solved, since I would like
to belong to the group of interested and positive Linux users.
Response:
Please give your solution directions to my email address "c.klarenbeek@hccnet.nl".
Thank you in advance for your attention and effort to help me.
