hi all,
i did yum -y install akmod-nvidia and then type xconfig-nvidia on the terminal,and after logging off i confront with a blank screen,
so i remove akomd-nvidia [yum remove akomd-nvidia] and also yum erase xorg-x11-drv-nouveau [yum erase xorg-x11-drv-nouveau]
but still no gui,
i think i should install:
yum install kmod-nvidia
xorg-x11-drv-nvidia-libs.i686
xorg-x11-drv-nvidia-libs.x86_64 [but i didn't]
so how can i have my gui back?
should i reinstall my fc12?
thanks in advance

You did not mention which nvidia card you have but here is a step by step guide for installing drivers on fedora 12

nvidia drivers

geforce 8600m GT,
will yum update command update every software?
and does 64 bit use the PAE kernel?

From what I have read all the 64 bit use the PAE kernel. I can not answer your question on update.

I had conflicting issues with installing kmod-nvidia, the nouveau driver not wanting to die. I removed it and renamed nouveau.ko to nouveau.ko.backup and finally added rdblacklist=nouveau

thanks for helping,i find something maybe helpful:
to determine if your kernel is PAE or not just type uname -r If the output does not end in PAE you will need the standard kernel module. If it does end in PAE you will need the PAE kernel module.
and in order to Keep nouveau from loading:
in terminal:
su -c 'mv /boot/initramfs-$(uname -r).img /boot/initramfs-$(uname -r)-nouveau.img'
and also:
su -c 'dracut /boot/initramfs-$(uname -r).img $(uname -r)'
To use the default initrd, but disable the nouveau driver, edit /etc/grub.conf and add the following to the end of the line(s) starting with 'kernel':
rdblacklist=nouveau
the first time when i install fc12 64bit and not perform the yum update command,when i try yum install komd-nvidia [with rpmfusion free&nonefree installed] it told me that there is no package but there were akmod-nvidia [that i've installed],after goggling i found that i must have rpmfusion free and nonefree and also the test [if i'm right] and also to run the yum update command at first,as i'm still on dial up my question is would yum update,update every package on the system?
and WreckeD do we have the same problem!
