This is really annoying. I had an installation of Suse 12.1 with KDE 4.7.2 and every time I shut down there would be a crash notice pop up with something about plasma crashing. No error log, I assume because this was the last thing that the computer did before shutting down. Every time I rebooted the panel would be opaque. If I rebooted again immediately it would be translucent again. I lived with this for about a month. Then my partitions became corrupt. ( Probably because of a power surge during a storm and my UPS failed. )
Then I did a fresh 12.1 install on a new HDD from a freshly burned iso. It is a very basic install on a 64 bit machine with a Nvidia GeForce 9600 card. You guessed it. The install is not a week old and I have the same problem all of a sudden.
I have similar problems on a pc with AMD/ati driver
My suggestion is to close all files and applications before shut down
Occasionally I also get the message when opening a file, ‘file was not closed
properly, do I wish to recover it’
Up to now recoveries have been successful
No consistancy has yet been found in these glitches
Thanks for the answers everyone. I was wondering if the export KDE_DEBUG=1 solution just stops the error reports or if it also fixes the panel opacity too?
I saw a thread that recommended upgrading to KDE4.7.4. Is this recommended or am I likely to break something by mucking up the repositories I subscribe to? I have done that before.
The export KDE_DEBUG=1 solution does just stop the error reports. I am not aware of the panal opacity problem to which you are referring. I have opacity in my panels but I thought that feature was based on the theme that you are using. I am also running KDE 4.7.2 which is the default version for 12.1. Feel free to upgrade to other versions, however, it has been my experience that things go smother with the default versions and so I’ll wait until OpenSUSE 12.2 to upgrade. Of course, I don’t know when 12.2 is going to happen because of this:
