i downloaded some software yesterday from the ubuntu rep. This morning my screen has the bottom part of in black there are the KDE docky ,firefox ,terminal & rhythmbox icons ,so is the taskbar..but the wallpaper is cut up ,4cm off.
I have noticed that the splash screens res has changed too. it's sharper (smaller).
The browser as a consequence is also half lit & having noscript in the bottom without it being visible is a problem ..
Why has this happened & how can i fix it. the last working config , well that's somewhere else
