Anyone know how? Oh dear. Firstly, I suspect that's Hewlett Packard's default response for Windows problems. I wouldn't be too sure that the HP rep actually realised that this "Fedora" and "yum" and "Linux" business actually mean you aren't on Windows... Secondly, it's not necessarily a video driver problem. It could be hotplug rewriting your xorg.conf file, or oddities in a new kernel, or even your hardware beginning to go... If you've installed separate drivers from Nvidia, ATi, Livna, ATrpms, or somewhere else, then you almost certainly have a "different version" problem between that driver and the rest of Fedora. Tell us more, and we'll try to help you fix it. Otherwise, you've got a couple of options. The first one is to try to fix the video card. Tell us which video card you actually have. It would also help if we knew what you mean by "flaking", and a bit more about the rest of your computer (which processor, etc.) If you're not sure how to do that, post the output from running /sbin/lspci and uname -a from a terminal (command prompt). The other option, as you suggest, is to "roll back" the yum update. Unfortunately, you can't use yum for this, which means you have to use RPM and handle dependencies yourself. The package that contains the standard drivers is called xorg-x11. You should be able to check which version you're running now by running rpm -q xorg-x11 (from a command prompt). You'll get a response somewhat like xorg-x11-6.8.2-37.FC4.49.2 You can find which versions you have been running by running: grep xorg-x11-6 /var/log/rpmpkgs* which queries a number of "snapshots" of what was installed. You can see when they were taken by running ls -l /var/log/rpmpkgs* Once you've found out which package you'd like to be running, you need to find a copy of it. Try Google, or your Fedora install CDs, or http://download.fedora.redhat.com/pub/fedora/linux/core/4 . Then you'll have to run rpm -Uvh --oldpackage xorg-x11-*.rpm That will probably show you an error that certain other packages need the current version of xorg-x11. You'll have to identify contemporary versions of those packages, and add them to the end of the rpm command line. You'll probably want more advice if you go this route, too. The --test argument to rpm, for example, rpm -Uvh --test --oldpackage xorg-x11-*.rpm will mean you can see what would happen if you installed an RPM without RPM actually going ahead and installing it. You may hear about the --force option. This should probably be renamed --force-until-it-breaks, or just plain --break. Don't use it.
