redhat8 and xfree86..tried everything i could think of

[Need4Speed]

Ok, so this is driving me nut...ive been trying to increse the refresh rate on my monitor, and for the life of me I can't get it to stick.

My monitor is a samsung 900ift and the vidcard is G4 4600. It's almost like win2k/xp in that i can't get it off 60Hz 🙁
Ive tried editing the XF86Config file and adding to proper modelines for the monitor under the monitor section as follows:

Section "Monitor"
Identifier "Monitor0"

XFree 4.x generally does well enough without any modelines - have you tried without them?

 

[Need4Speed]

yeah, but for some reason my monitor fails the ddc probe everytime.

The problem is not with the monitor it is with the driver. With the vesa driver the best that you will get is the 60Hz. My suggestion- pull with src rpms from Nvidia and do the following

rpmbuild --rebuild NVIDIA_k*.rpm
rpmbuild --rebuild NVIDIA_G*.rpm

cd /usr/src/redhat/RPMS
rpm -ihv NVIDIA_*.rpm


edit /etc/X11/XF86Config -

remove the following line

load dri

and change the Driver "vesa"
to Driver "nvidia"

reboot and you should get 85Hz and an nVidia splash screen

Or drop the framebuffer and go with the nv driver instead of vesa. Framebuffer is nice and all but it just constrains you in X (for that matter I would have thought the nvidia drivers wouldn't work with the framebuffer either...)

 

[AkumaBao]

Man, get rid of those Vesa drivers! Compile the NVIDIA tarballs, and use the good ol' 'nvidia' driver. Use RPM's if you want , but I've seen problems occur from the RPMS vs the tarballs. Just remember the NVIDIA_kernel package goes first. 😀

 

[Need4Speed]

I attempted to do just that...install the nvidia drivers, but I kept getting an error when I running the rpmbuild on the kernel source. I don't have the error handy at the time, but I'll try to post it later.

Thanks for the advice.
