=======================================================================
Odd behaviour of desktop etc.
1) init attempts to use dhcp rarp on ethernet port that is not connected (5 minute delay) the defaults, later after desktop installs, to WiFi (this works)
2) desktop fails several times to start. init eventually succeeding (after 3 minute delay)
3) Once desktop starts, Cadence and a basic file browser start on screen before desktop completes.
4) Thereafter, virtually any situation where a window is opened from inside another window, such that the new window covers the opening window, causes a kwin crash.
5) "System settings" do not apply to plasma desktop. E.g., I set double mouse click to open desktop icon, but it always remains at one click. BUT, I set a background image for the desktop and that worked (??)
6) Latest crash took image off desktop (first time) and replaced with black background. ON THIS DESKTOP ONLY DOUBLE CLICK WORKS (??)
7) I tried to send a bug report, and the bug report will not log me in, however I used Firefox login and am writing this.
