Im having problems where occasionally the screen fails to refresh properly. It looks like a tv when the cable signal goes out If I log out and log back in everything is fine. Below I've given some highlights of my system if anyone could englighten me of how and why this could be happening.

Thanks in advance for any information

Are you using the fedora/livna-sourced nvidia driver?

I found the livna rpm in my list (I never installed this though from livna.org, does this come with FC4 distribution)

[jwstric2@localhost ~]$ rpm -qa | grep liv
livna-release-4-0.lvn.7.4




Doesn't mean its being used properly though. I was looking through used modules for the appropriate module..

Have you read this...
https://www.redhat.com/archives/fedo.../msg01178.html
??

And for the solution, go here:

http://www.stanton-finley.net/fedora...es.html#nVidia

It's for FC5, don't know if it'll work with FC4

siemour: Stanton Finley (on an absolutely aweful web page) advises to use www.mjmwired.net ... to enable the livna repo and obtain the nvidia driver via yum.

This will not fix the problem if the nvidia driver has been installed from the nvidia site. The information to fix the problem, including the advice given by Stanton, is included in the link provided in post #4.

However - it is entirely possible that the nvidia driver has not been installed, since the xorg.conf is using the "nv" driver. I'm waiting for feedback from jwstric2 before proceeding with specific advice.

Certainly:
www.mjmwired.net is an excellent resource, folk new to fedora should also check out www.fedorafaq.org (the fedora faq) and www.fedoraforum.org (official fedora project forums - which are, oddly, not as good as here.)

Note: FC5 has a graphical interface for YUM (Pup) in which you can enable or disable the repos you need without resorting to CLI jiggery-pokery. The same functionality is provided for FC4- by Yum-Extender which is anstalled using the yum.conf from the fedorafaq and yum install yumex.

http://www.linux.com/article.pl?sid=06/03/08/2321254
I see yumex is available for FC5 and is better than Pup.

Thanks. I ended up reading through Simon's info at https://www.redhat.com/archives/fedo.../msg01178.html I ended up completely cleaning off some package discrepencies and getting the "good" driver packages from livna.org. It wasn't a simple solution but it works.

Once again .. thanks.

Well done. Just goes to show how careful you have to be.
BTW: nvidia know about this problem, and have their own solution for it in their own forums. I still think the livna one works better since it is packaged by people who know the ins and outs of fedora much better.

You were lucky - in my case I ended up with windows-like crashes and hangs (about once a day) and when I did the check, there were thousands of packages affected. In the end it wa simpler to backup and reinstall ... so I chose a distro easier to install... which is why the "FC4" vanished from my profile. (Also, keeping one distro uptodate is simpler and cheaper than multi-distros.)

BTW: you should consider editing your profile to include a location and distro. Stps folk from having to keep scrolling back (sometimes several pages) for a reminder.
