I'm having the same problem, and it seems to be clearly related to plasma. It happens very frequently if I am in the plasma dashboard. Otherwise it might happen when I click on a plasma panel.
The mouse cursor will still move fine so this isn't an normal X crash or a system crash. However, I will not be able to click on anything, nor does typing work, nor all the usual reset key combinations. Finally the screen will stop updating (apart from the moving mouse cursor). For instance if open office is on the screen the input cursor will stop blinking. The minutes of the clock on my plasma panel do not update. I think the biggest problem that linux has with new adoption is simply its stability. Constant problems, even though I bought a computer with linux preinstalled (inspiron 1420). Every time there is an new ubuntu release coming up I keep thinking to myself, this time, this time it will be stable enough to really recommend to my friends and family. And every time it is a nightmare. Even though I've been using linux exclusively for nearly 10 years, I know that most of the people I know would not be able to figure it out. People keep talking about desktop linux and wondering when it will take off. The answer is obvious: it will take off when it starts to work consistently (if that every happens). If it actually worked, I think I could convince about 10 friends and family to switch over, but it doesn't. -- kubuntu 9.04 freezes all the time https://bugs.launchpad.net/bugs/337351 You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. -- ubuntu-bugs mailing list [email protected] https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
