Hi to all, I have a problem with my screen. I use KDE as my GUI and the windows appear with a shadow in all the screen. What i mean by a shadow is like several lines (more like shadows) which appear in the horizontal direction and appear in the windows edges. There are also other shadows which appear in each line of text that i am writing. When i move the window the shadows follow it . Perhaps this is a X server problem, or it might be a hardware problem (monitor or graphics card). I have plugged the monitor in another computer and the shadows did not appeared, so i presume this is not a monitor problem. I have run the X wizard to reconfigure the X but it remained the same. Is this a graphics card problem ? I do i trace the problem ? Thanks to all in advance. P.S: sorry about my english
