Freeze (Black Screen) on startup/shutdown

I have recently upgraded a computer from FC3 to FC6. Under FC3 I would occasionally get a lock up on shutdown where the screen would go black with green spots on it (mainly black). This only happened once every couple of months however.

After upgrading to FC6, I am having the same thing happening, but it is much more frequent and happens on both startup and shutdown. I would say this occurs about 1 in 2 startup/shutdown cycles.

The computer is a P4 3GHz with a GeForce FX 5600. At this point I was using the Nvidia 8776 driver (prior to the reinstall, I was using 7667).

I have tried updating to the latest nvidia driver version (9746), but now the same thing happens except the screen in completely back - no more green spots.

I also disabled graphical boot, which stopped the freezes on startup, but the shutdown ones continue.

It seems to me to be related to the video card, but I don't really know. The system is rock solid once it is up and running.

I would be very grateful if anyone has any ideas. Here are the relevant bits of /var/log/messages showing where it dies:

I have recently upgraded a computer from FC3 to FC6.

Is this an upgrade (i.e. anaconda upgrade option) or a fresh installation?

How is it with the open source nv driver?

So this is a mythTV system?
http://wilsonet.com/mythtv/fcmyth.php
... some stuff has changed.

Thanks for your thoughts.

Sorry for the ambiguity. It was a fresh installation.

I have not tried the nv driver. I guess that is the next thing I should try, but the system is currently only connected to a TV which I believe makes it a little more difficult.

It is indeed a MythTV system, and I did install with close reference to Jarod's guide.

Hmmm... did you follow jared's guide very closely - like using apt-get and everything? I note the guide is expressly for FC3 - some intellegence is needed to modify the commands. A direct copy and paste won't work.

I don't know about the axel packages nvidia driver - most folk use the livna packaged driver for FC6 (yum install kmod-nvidia). Nobody uses the official nvidia installer because it breaks fedora's X configuration in many subtle ways.

Looking at the official howto
http://www.mythtv.org/wiki/index.php...on_Fedora_Core

check your installation against the official howto. Do this slowly.

... thing is, there is no apparent error message.
I take it this is a hang with black-screen?

Check your xorg.conf - usually the thing for black-screen-of-death. But you usually get an error.

The latest version of Jarad's guide is based on FC6. I followed it reasonably closely, making any necessary changes for my different hardware etc. I have a reasonable linux knowledge and understand everything I was doing - certainly not a blind copy/paste.

I will have a good read through that howto later, but I doubt it will be of much assistance. The problem seems to be with the OS rather than the mythtv component. It is a hang with black screen, and it is intermittent, so it seems to be a bug in something rather than a configuration problem (to me anyway). Of course I may only be seeing the bug because of a configuration problem.

I can't see a problem with my xorg.conf, but here it is if you want to have a look:

Code:

[root@mythtv ~]# cat /etc/X11/xorg.conf

Thank you for spending the time to make suggestions.

I ended up replacing the video card with a 6200. It seems to be working properly now. Thanks for your help.

Which places doubt on the "OS specific" speculation and looks questioningly at the hardware...

I think it is quite possible that there was a hardware issue, and the upgraded software aggravated it a little more.
