I use the wonderful synaptic and it recently upgraded my kernel for me. Following a reboot, however, I had lost NTFS support (I sort of expected that) and the driver using Twinview for my NVIDIA Geforce 4 had stopped working....

I have tried to rebuild the driver for the new kernel using the source RPM and the source TAR file but neither works:

Also I think the generic NVIDIA driver that comes with RH9 does not support Twinview as the secondary monitor is on standby all the time... Any thoughts or help would be appreciated. (p.s. I have tried to recompile the kernel with the non-source RPM for NVIDIA installed but that fails with 'ERROR 2' too.
