Description JHanlon 2009-01-28 16:41:53 UTC

Version:            (using KDE 4.1.96)
Compiler:          n/a 
OS:                Linux
Installed from:    SuSE RPMs

From uname -a:
Linux buchanan 2.6.27.7-9-default #1 SMP 2008-12-04 18:10:04 +0100 x86_64 x86_64 x86_64 GNU/Linux

Following multimedia checklist in openSuSE forums, entered " LC_ALL=C zypper ve" on root CLI. Some versioning anomalies detected, with a reasonable-seeming choice of upgrading from 4.1.96 something to 4.2.xx something (Details not available at the moment). 
Restart X via Ctl-Alt-Bs-Bs, relogin to 4.2 --> no desktop, gray screen, KDE crash handler window appears. It requested sending in a detailed report, so here's the output:

--------end of crash window output  ------
This is repeatable.

Apparently, I am in a unstable versioning situation. The Konqueror About window reports as follows:
" Konqueror
Version 4.1.96 (KDE 4.1.96 (KDE 4.2 RC1)) "release 78.1"
Using KDE 4.2.00 (KDE 4.2.0) "release 82.2""

Rerunning the "LC_ALL=C zypper ve" command brings the report: "Dependencies of all installed packages are satisfied.". Reassuring.

I will see what other windowing systems are available on the system, the better to sort out what is wrong with KDE 4.2 now.

Comment 2 JHanlon 2009-01-28 18:52:51 UTC

It was a versioning anomaly. Updating unconditionally, via Yast, as recommended in the opensuse forums resulted in a stable login following a shutdown of X via Ctrl-Alt-Bs-Bs. Be aware that the download was over 512 MBytes.

Recommend close this report.
