Version: unspecified (using KDE 4.4.2) OS: Linux I installed Kubuntu 10.4 from live CD and updated the software. This is the first time, am using Kubuntu/linux on my acer aspire 5100. Closed my laptop - goes to suspend or sleep state and opened after coming home. Now, the background of the login screen shows invalid screen - blue bars and junk screen. Could not able to find mouse cursor, and after playing for a while - could able to login and the mouse cursor still looks like a rectangular blob. Reproducible: Didn't try unfortunately, mouse cursor is not captured in screen shots
This sounds like a graphics driver issue, not correctly handling suspend/resume cycles. Which graphics chipset does your system use?
most likely a graphics driver problem, indeed
