Description Matthew Smith 2009-07-02 14:39:47 UTC

Version:            (using KDE 4.2.4)
Compiler:          gcc version 4.3.3 (Ubuntu 4.3.3-5ubuntu4) Target: x86_64-linux-gnu Configured with: ../src/configure -v --with-pkgversion='Ubuntu 4.3.3-5ubuntu4' --with-bugurl=file:///usr/share/doc/gcc-4.3/README.Bugs --enable-languages=c,c++,fortran,objc,obj-c++ --prefix=/usr --enable-shared --with-system-zlib --libexecdir=/usr/lib --without-included-gettext --enable-threads=posix --enable-nls --with-gxx-include-dir=/usr/include/c++/4.3 --program-suffix=-4.3 --enable-clocale=gnu --enable-libstdcxx-debug --enable-objc-gc --enable-mpfr --with-tune=generic --enable-checking=release --build=x86_64-linux-gnu --host=x86_64-linux-gnu --target=x86_64-linux-gnu Thread model: posix
OS:                Linux
Installed from:    Ubuntu Packages

I have found that my screen flickers while loading KDE.  This happens sometimes but not all the time, and with both GDM and KDM.

The splash window will disappear and the background image will elongate vertically, so that the circles become oval.  This happens several times during most of the stages of startup, in between which the icons will fade in as normal.  After startup, the flickering continues, with the screen background repeatedly changing from colour to B&W and back again, and the bottom Plasma panel disappearing.  My desktop was un-usable and my only way out was Ctrl-Alt-Backspace.

This happened several times yesterday, but the day before, the flickering happened but not the corrupted desktop; today, KDE loaded without incident.

I am using the KDE 4.2.4 update packages supplied through Ubuntu's Launchpad - http://www.kubuntu.org/news/kde-4.2.4

The flicker remains me some report about a flicker when the user had dekstop compositing (effects) and it was being activated during the login.

The B&W and plasma panels dissappearing looks like Plasma was crashing and restarting.

However, you said you are not experiencing that behaviour anymore.

Which are the problems you have now, only the first one ?

Thanks!

This bug is 9 years old and is to do with KDE 4.2 which I haven't used in a long time and I suspect nobody else uses it either. Feel free to close it.
