Which to use 32 bit or 64 bit linux

Short answer use 32-bit if you have 3G of ram or under. If you have 4G of ram or over use 32-bit with PAE (kernel-PAE).

Currently adobe flash isn't 64-bit on linux. (only beta drivers exist) The gain you'd get for 64-bit kernel just isn't worth the hassle if your not an expert. PAE can support up to 64 G of ram so your good, just run 32-bit.

Installing NVIDIA Display Drivers in Fedora

There are many graphics drivers that are included in the Fedora repositories.  However, the best drivers, in my opinion, for the NVIDIA graphics line is NVIDIA's proprietary drivers.  They have full Linux support, but the drivers are a bit of a pain.  Every time you get a new kernel you need to re-install them.  (There are automatic programs like kmod, but the following keeps things simple and consistent)

The symptom:  (You have a NVIDIA card, it was working and this is all you see now)

The above is assuming a few things.  The standard Fedora setup includes experimental 3d drivers, and 2d drivers for NVIDIA.  So if you've never installed the NVIDIA drivers and you get this prompt, you may have another problem.  Check the /var/log/Xorg.0.log file for clues.  (or login type "more /var/log/Xorg.0.log")

Installing the drivers:

1. Login as yourself (or root if you have that password).

2. If your logging in as yourself you then need to do "sudo -i".  To go to the root user.
3. Type "init 3"  This just makes sure your graphics server is shutdown.   The installer will complain if it isn't.
4. Type in "ls NV*" to get the file name.  This will depend on what driver you've downloaded and is for your card (check NVIDIA Driver Download Page for more info)

Then type "./<filename of installer>".  The "./" just means run the program from that directory.

If there is no file then you need to download it.  Try copying to a CD, usb key, or you can try downloading via "links" or "links".

5. Now your at the licence page.  Accept to proceed.

6.  Answer "Yes" to any configuration questions.   (When in doubt, answer yes or pick the default)

7. Your done.  Now either type "init 5" to start-up graphics login, or just reboot by typing "reboot".

Typing init 5 will allow you to start using your system without the need to reboot.   But for those users used to windows, a reboot at this point doesn't hurt.
