Version-Release number of selected component (if applicable): Fedora 13


How reproducible: always


Steps to Reproduce:
1. upgrade Fedora 13 to latest 
2. click on vnctiger icon (i tried to run vncview as well, same result)
  
Actual results: screen freeze, keyboard has no response, but i can ssh into host from another host

This is weird, it seems like a graphics driver issue than vncviewer issue. Would it be possible to attach dmesg output and /var/log/Xorg.0.log, please?

Can you please ssh into frozen machine and check if Xorg process simply hangs or if it consumes 100% CPU time? Thank you in advance.

xorg.0.log, this should be the right one

Comment 4 Adam Tkac 2010-07-22 06:05:24 EDT

This really seems like graphics driver issue for me. Reassigning to nouveau driver for further inspection.

Comment 7 Yi Zhang 2010-09-17 14:09:40 EDT

I tried update my video driver this morning, and the problem seems gone.

I disabled "nouveau" driver and installed the one from nVidia. After reboot, I don't see the freezes anymore. 

Thanks for the hint. I am pretty sure this is video driver related problem

I will close the bug.
