Description Yi Zhang 2010-07-02 11:54:20 EDT
Description of problem:
I upgrade Fedora 13 this morning. After reboot, i click on tigervnc icon on my gonme-panel, and it freezes the whole gnome screen. Keyboard has no response at all. I reboot host again and tried vncview, it does the same thing. 

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

Additional info:
my laptop is lenovo t60 
[root@works4you ~]# uname -a
Linux <workstatation name> #1 SMP Fri Jun 11 09:38:12 UTC 2010 x86_64 x86_64 x86_64 GNU/Linux

I tried downgrade tigervnc 
(tigervnc-1.0.90-0.12.20100420svn4030.fc13.x86_64) to 
(tigervnc-1.0.90-0.8.20100219svn3993.fc13.x86_64), but I still get same problem

[root@works4you ~]# rpm -qa | grep tigervnc

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.

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.
