I loaded a new Dell pc with FC10, most items seem to run great, deluge, firefox, mythtv. However, when I try to run avidemux, vlc or k3b, nothing happens. I got to the system monitor and look at my running processes and is says "sleeping" (no quotes) for the status and I see futex_wait and do_select. I have no idea where to really look, as this is really the first failure I've ever had for fedora. Just tell me what I need to post, I know I haven't put enough info out, but I have no idea what to do here. As always, help is greatly appreciated!

I have no removed nearly all software, and tried to install vlc, and nothing. I check the processes and see its "sleeping" with the futex_wait. K3B still tries to load, and stops at creating gui. I have no idea what is going on, as my other FC10 just worked after loading it. Firefox, deluge are running fine as are all other services I have tested, samba, vnc, ssh.

Try logging in as unprivileged user and openening a terminal window (xterm, Kterm or whatever it'll be called). Then run one of those applications like: 'vlc 2>&1 | tee /tmp/vlc.err'. This will start the application and output both stdout and stderr to your terminal window and the "/tmp/vlc.err" logfile. If nothing shows up on screen or in the log see if you have an ~/.xsession-errors that maybe contains error lines. Else see /var/log/messages and /var/log/audit/*.

I didn't see anything in the logs, but I believe I found my problem. A fedora 9 repo and 10 repo. I've reloaded and fixed my repo issues, all works great. Thanks for your help.

You've found the "fix" yourself: well done!
