Forgot to say what I found and how I solved the issue:
- Nividia refuses to provide the open-source community with the technical infos necessary to write drivers, and instead, provides its own, closed-source drivers.
The open-source alternative is "nv", which came with the Ubuntu 9.10 liveCD I have. "nv" is now deprecated, and has been replaced with "nouveau". "nouveau" is still not as feature-rich as the Nvidia drivers, but may be good enough for your needs
- There are actually two drivers for a video card: /lib/modules/2.6.31-20-generic/updates/dkms/nouveau.ko is the driver itself, while /usr/lib/xorg/modules/drivers/nouveau_drv.so is the part required for X
- Before installing "nouveau", remove "nv" if installed
- Provided the Linux kernel you have was compiled with support for loading drivers dynamically (I guess all kernels these days are compiled that way), adding a new driver doesn't require recompiling the kernel.
- Just run "apt-get install" to add a new driver, and edit /etc/modules/ to make this permanent
- Since Ubuntu 9.10, the X server (Xorg) no longer creates a /etc/X1/xorg.conf by default, and tries to figure out the chipset + monitor you have. It if doesn't work, you can generate your own xorg.conf either manually or through "Xorg -configure" (which will create ~/xorg.conf.new)
- "gtf 1024 768 75" generates the Modeline instruction (to get 1024x768 @ 75Hz in this example) that you can copy/paste into xorg.conf.
Caution: In Modeline, ".00" totally crashed my Linux without any error message... :-/
- While running X, you can check the current configuration with "xrandr"
- If the screen is not lined up correctly, eg. the picture is a bit too far on the left or on the right, run "xvidtune" (as non-root, at least with the liveCD I have), and make the settings permanent by copy/pasting them in xorg.conf
- In the liveCD I had at least, to switch from the default US keyboard to the FR keyboard, I have to run "setxkbmap fr" as non-root. I haven't figure out yet how to make this permanent, in both X and in the console
- Runlevels 3-5 in Ubuntu all boot in X; To boot in text mode, use runlevel 2.
Here's the whole shebbang:
