GUI lockup with no activity but wakes with keyboard or mouse move

[MGKandziora]

Hello all,

Using openSUSE 11.1 with Labview 8.6.1.  I've noticed that the GUI locks up at random times and requires a mouse move or keyboard tap to continue.  I've created a test vi that is a simple while loop with a timer and a toggle on a boolean, so there is nothing going on in the code and it easilly shows the problem.

During the lockup, the system clock in the tray freezes as well, but no time is lost.  Upon the mouse move, the clock jumps ahead to the right time, so the OS is still doing its thing.

Is this a known issue?  I've new with Linux and am getting a feel for it.

Thanks,

Michael

If it affects the system clock then it can't be a LabVIEW problem. Are you running in a virtual machine? I have seen similar behavior to that in VMWare, and it's something that the VM is doing and not the Linux OS. If not then it's gotta be some kind of X Windows behavior.

Are you using KDE or GNOME under Opensuse 11.1? There are several offenders in both the desktop environments. If its KDE, then try turning off Special Effects the same goes for GNOME, turn off Compiz. Additionally, under GNOME, there's a huge memory hog of an application called Beagle which indexes files. Remove it, its pretty much of little use.

Can you run the command in the terminal:- "free -m" and paste the output? It may help in diagnosing how much of memory is being used by your system.
