Hi Edison. No idea, so I will give you some hints.
I noticed that when you first start e.g. df_window, and only then testman, some redraws are missed, but this is a minor issue and does not cause locking up of the system. This is on a recent X11 system. Your versions look ok to me. If you cannot use gdb to see where the application is stuck, I would advise to build directfb with debug and trace options: --enable-debug and --enable-trace. If you then stop an application with control-C, it will dump a stracktrace of all the threads running. Also, you can check /proc/fusion/0 for the files there, to see if there is a lock still pending at the moment. look at the file called skirmish, here you can see which process ID is taking the lock, and - if there are any - which IDs are trying to take it, and therefore waiting. If you have a deadlock then obviously on skirmish X app A waits for app B, and on skirmish Y app B waits for app A. Greets Niels Edison_lin-林俊翰 wrote: > Hi, > Please allow me to make a complement.
