AGPGART disabled, FX 5950 Ultra, Fedora Core, help!
I've just installed an FX 5950 Ultra on a 3.0 GHz Dell dimension running Fedora Core from the NVIDIA-Linux-x86-1.0-5336-pkg1.run installer.
With X11 running my entire system is *v*e*r*y**s*l*o*w* -- it's painful to use. Windows paint slowly as if under software control with no hw accel. Even the time of day clock runs at half speed! Something is seriously wrong.
This is in a corporate environment with standard configs, our sysadmin is stumped. We have several similar systems and they work fine.
When I look at /proc/driver/nvidia/agp/status I find the AGPGART is inactive and Fast Writes are disabled:
[Wazoo@Wazoo-linux nvidia]$ cat /proc/driver/nvidia/agp/status
Driver: AGPGART (inactive)
AGP Rate: 8x
Fast Writes: Disabled
Any clues? In /var/log/XF86config.log there is a warning "Failed to verify AGP usage". This seems relevant, but where to go from here?
