alright, i just reformatted and installed fedora 12 after my windows install had horrible driver issues. so, i installed fedora 12 easily, but the screen was very grainy, every other pixel is white. so far i have tried a couple commands to fix it. first i used the
yum list akmod-\* \*-drv\* kmod-\* dkms-\*
command from the unofficial faq, and then did what was told from this website

http://mariuszczyz.wordpress.com/200...-installation/

those 2 things are the only things that seemed to have a effect. i've been spending a couple hours trying to find solutions but nothing seems to apply to my problem or work. i am using a dell lcd monitor and a nvidia geforce 7300 gt.

so that it's not neccesary to check the website what it told me to do follows:

Add this to the end of kernel directive in /etc/grub.conf:

1 nouveau.modeset=0 vga=0×318

Next, install additional repo rpms:

1 rpm -Uvh http://download1.rpmfusion.org/free/...ble.noarch.rpm http://download1.rpmfusion.org/nonfr...ble.noarch.rpm

Follow this by:

1 yum --enablerepo=rp*g install kmod-nvidia.$(uname -m) xorg-x11-drv-nvidia-libs.i686 xorg-x11-drv-nvidia-libs.x86_64

Finally:

1 reboot

Fedora may have set up a range of resolutions during the installation. Try ctrl-alt-+ (that control-alt-plus (on the number pad)) to increase resolution.

i did so with a couple different arrangements of control and alt, and nothing seems to happen (as in i did left ctrl and right alt, left ctrl and alt, with numlock on and off). i did go into display settings and there was a unknown and a dell monitor. the unknown had lower resolution options than the dell one so i switched to the dell. i didn't think that was relevant so i didn't mention it because it seemed more a driver issue than a resolution issue >.<

i will say that upon manually switching resolutions around the problem hasn't changed, it's just that it becomes slightly less noticeable at higher resolutions

also i have tried loading pictures and pictures load without any distortion, text however is very hard to read without increasing it's size signficantly

May be the Fedora default nvidia driver "nouveau"
is disturbing ...
