Since I updated XFree86 a week or so ago, it just keeps failing to initialise the NVIDIA module. I tried X.Org, which does exactly the same. Looking at the log, everything seems to start up properly with no errors, but suddenly it decides to give up, no reason given.
I have just discovered that if I uninstall, reinstall and modprobe the the NVIDIA drivers, it works! Until I reboot. Then, no matter what I try, it will not work at all! So I have to uninstall, reinstall and modprobe each time I reboot.
Very weird is all I can say.
try adding nvidia to rc.conf's modules list
that should do it
there is also a nvidia package in the staging repo
which gives you hints about installing
pacman -S nvidia
Well, I had done that, but the point was that once I restarted, whether the nvidia modules was loaded by /etc/rc.sysinit or manually with modprobe, it would not work (but modprobe did not report any errors). The /dev/nvidia* devices do not show up.
Seems the problem is with UDev (maybe I needed to configure something for it?). I have switched back to DevFS for now, and it works again (X.Org). I had forgotten when I posted that I had also switched to UDev at the same time...
I still have another slightly related problem. I recently (yesterday) had this idea that maybe I should try get my (hardly ever used) Lucent winmodem working under Linux for the odd times I use dial-up. Drivers were easy to find (http://linmodems.org/). This worked under UDev, but then stopped working when I restarted (grr), the same as NVIDIA, whether they were in MODULES or whether I modprobe'd 'em. I actually got KPPP to dial on /dev/modem and it would have authorised had I bothered to configure PPP daemon first ;-) Didn't work under DevFS either, even though the install script had added a rule in /etc/modprobe.conf to alias /dev/modem which doesn't materialse. The device does appear at /dev/tts/LTM0 but KPPP can't dial on it.
I believe it was also added to the udev wiki. You need that nvidia script to generate your devices.
