Hi, This is the message I posted during my first fedora installation. https://www.redhat.com/archives/fedora-list/2006-July/msg00120.html but after my third installation of fedora 5 in three computers, I was able to reproduce the same error since all the computer have same nvidia cards( but different processors and motherboards). These are the steps I had taken during installtion of nvidia ------------------------------------------------------------ 1. after fresh installtin of FC5, i had my kernel update, and update of all the pacakges. In My first and second Installtion (KDE is selected as only desktop without Gnome): 2. installed the kmod-nvidia from livna. Here everything went fine (KDE runs well) except when I tried to select the screensavers from KDE desktop, it gave me some error message saying something like that (I couldn't remember the exact message): "error on /usr/lib/modules .... somelibraray prot error ... permission denied ... relocating" and KDE diagnosis says there are some old modules are lying around since last upgrade to KDE 3. after that I removed the kmod-nvidia (but dependencies were not removed), downloaded the driver from nvidia and followed the instruction in their post http://www.nvnews.net/vbulletin/showthread.php?s=70f557195fc775142542927bfcf69659&t=72490 This time everything went fine and I can now use the GL screen savers. My Thrid Installation: ---------------------- 1. this time I selected Gnome and KDE both during installtion and using Gnome as dhttp://www.google.com.ph/search?q=fedora-list&start=0&ie=utf-8&oe=utf-8&client=firefox-a&rls=org.mozilla:en-US:officialefault desktop. 2. Did update as before 3. This time thinking there is something wrong with kmod-nvidia, I tried the nvidia driver first and set the necessary SElinux permission. 4. To my surprise, this time Gnome didn't like to start. To check, I first booted in run level 3 and manually started X but gnome hanged right after showing the fedora logo. 5. checked the console and found the error similar to the one I previously found in KDE stating something like: "error on /usr/lib/xorg/......nvidia... prot error .... relocating.... Permission Denied" 6. Switched desktop to KDE if if works and found KDE runs smoothly. 7. Tried to select the screensaver from KDE desktop and came to the same error message. 8. Now this time without uninstalling the nvidia driver, I installed the kmod-nvidia using yum. It checked the dependencies and installed the two pacakages and I reboot the machine. 9. Now its working fine with all the GL screensavers. 10. switching to Gnome again works well too. Having all this said, I guess there is nothing wrong with the driver itself (whether you choose to intall from nvidia or from livna) but something to do with the additional steps on setting permission to specific libraries after driver installation. Here I found that installtion of kmod-nvidia completed something which was left uncomplete with manual installtion from nvidia and vice versa. I guess this helps to figure out the exact problem and fixing it. Thanks a lot for all the help and suggestions.
