am a beginner Linux user and love Ubuntu for its simplicity and stability. But suddenly out of nowhere "there appears a line at the bottom of my screen it's orange in colour and in dotted form", it is pretty annoying having to look at that. So please help me to give some advice's of fixing it..
FYI I've updated Ubuntu and also have all the necessary drivers installed correctly.. everything was perfect and this problem just suddenly appeared.
I've clicked a pic since the line wasn't appearing on screenshots.
