Hello all, I did the same (double) error twice, with obviously the same result twice. The first time, I continue to use the system, which meant that I did not know where was the error. The objective was to install Firefox 5.0. 1 - I copied a directory /usr/local/firefox/ from a system used before 2 - I tried to edit a firefox icon coming also from the other system, 3 - I completely uninstalled firefox using Synaptic (that did not removed the ~/.mozilla/). At the end of stage 2, TDE changed their behavior: the icon (firefox) disappeared from the office, and TDE "showed" the launch of an application (clicking on a desktop icon) by in the magnifying. I had initially inhibited this option (called "bouncing cursor", I think). I do not know which of point two or three is causing the problem, but at the following reboot, TDE showed blue cursors and finally "Can not open theme file /opt/kde/share/apps/kdm/themes/kubuntu-kde3/ ". In the current working installation, there is no /opt/kde/ but /opt/kde3/. Once the session opened, there was no menu Start. (I am not ready to live without it!) I am currently with a screen size of 1152x864 that comes out of a magician's hat (this is the very first time it appens with THIS format!), while after the last system restore (and associated wasted time), throw in usual 1280x1024. I have already indicated the unsolved problem of ATI drivers installation in another post.
