I was going to add RAM to my notebook to a total of more than 4GB, and I have Ubuntu 12.04 32bit; so I installed the pae version of the linux kernel and booted with it to give it a try before I buy the ram.
My NVidia drivers, which work fine with the normal kernel (as fine as nvidia drivers can work), don't work when I boot with the pae kernel. My second monitor stops working, and when I try to launch NVidia Settings, it tells me that I'm not using an NVidia X Driver.
Now I've rebooted with the old normal kernel and everything works as before.
So, is there some sone bug or incompatibility between the pae kernel and the NVidia Drivers, or will I just need to reinstall (perhaps a different version of?) the NVidia driver if I want to start using the pae kernel?
(which in turn means, will I just waste money if I buy the additional ram?)
