How to Configure X11 Driver?

TOPIC: Configuring X11 Driver

This guide details the settings for X11 for your system

First Boot Module
As part of the First Boot of a graphically installed system, you may select your X11 Driver. This is the driver used for your graphics card.

NVIDIA Driver:
Use the properitary NVIDIA X11 driver. Required to run CUDA applications.

* This option only available if your system contains a Nvidia device.

X.org Driver:
Use the open source X.org X11 driver. This driver is all your need for running your graphics card, but it will cause system hangs when running CUDA applications.


Command Line
Swapping your X11 Driver after the initial installation is done from the comand line.

NVIDIA Driver:

yxc_cli.py --nvidia

X.org Driver:

yxc_cli.py --xorg

:( :cry: but where is the comand line? xorg is needed!

I don't run YDL for CUDA, but guessing, you probably need to be logged in as root. So try this before the command:

Code: Select all
su --login

<root password>
PS3 60GB [CECHA01], FW 3.15, YDL 6.2, Samsung T260HD @ 1920x1200
Powermac G4 1.25 GHz x2, 2 GB RAM, YDL 6.2

On my YDL for CUDA box, there's a file called system-config-yxc-cli in the /usr/bin directory, that appears to do what you're asking for. Here's what it looks like as root:

Code: Select all
[root@localhost paulp]# system-config-yxc-cli --help
usage: system-config-yxc-cli [options]

options:
  -h, --help  show this help message and exit
  --xorg      Use the open source X.org X11 driver. Will cause system hangs
              when running CUDA applications.
  --nvidia    Use the proprietary NVIDIA X11 driver. Required to run CUDA
              applications.
[root@localhost paulp]#


So - instead of yxc_cli.py, try system-config-yxc-cli with the same arguments. I'm assuming you can't get X Windows started, so you'll do this from text mode, right after you login. I believe you will need to be root user as well.

Cheers,
Paul
