There is plenty of information about Gentoo (Thanks God!), I am going to write here a very little how-to install Gentoo, then X, the Nvidia drivers, and Fluxbox, I will not go into details about Gentoo installation as there is enough in the official page.
Once you have your Gentoo Linux running, you can go to install nvidia-drivers, but first lets install sudo -Optional- (I like that sice I have used Ubuntu)
Now edit the sudoers file using the command:
And enter this line at the end of the file.
your_user ALL=(ALL) ALL
Now continue with the installation
sudo emerge nvidia-drivers
Then load the module into your Kernel,
sudo modprobe nvidia
Then install X
sudo emerge xorg-x11
Now configure X
Follow the instruction on the screen, be sure to know the vertical and horizontal sync rates for your monitor.
Finally install fluxbox
sudo emerge fluxbox
Configure it to be your windows manager
echo "exec startfluxbox" > $HOME/.xinitrc
And start it:
I got this error at this stage:
(EE) NVIDIA(0): Failed to initialize the GLX module; please check in your X (EE) NVIDIA(0): log file that the GLX module has been loaded in your X (EE) NVIDIA(0): server, and that the module is the NVIDIA GLX module. If (EE) NVIDIA(0): you continue to encounter problems, Please try (EE) NVIDIA(0): reinstalling the NVIDIA driver.
After googling, I found that the problem was that the GLX module loaded was the X.org module and not the nvidia one, so, solve the problem was as easy as enter this at command prompt.
sudo eselect opengl set nvidia
Now I have my first Gentoo with fluxbox on it running!!
