X -config hangs and doesn't produce an xorg.conf

Question

I am trying to generate an xorg.conf file for my current configuration. I am using X -config xorg.conf, but it doesn't produce a file.

Here is the output:

    # X -config  xorg.conf.new

It then hangs and never returns to prompt.

I did end up realizing that I was using the wrong command then ran into a bound kernel driver error. I then had to blacklist the driver for some reason in order to get the xorg.conf file.

Solution 1

Switch to the console mode , then stop your display manager.

To generate the xorg.conf.new file you should use the Xorg -configure command, it will be located under /root/xorg.conf.new

Move the /root/xorg.conf.new to your /etc/X11/xorg.conf

Finally start your display manager.

Debian-WIKI : What if I do not have an xorg config file?

Solution 2

Xorg -config doesn't show you your X configuration, it is used to start an X server with an alternate one. You got the suspension, because your X server probably started, somewhere on an alternate console.

Try Xorg --configure. It autodetects the hardware and dumps the generated X configuration.

Thank you. I did end up realizing that I was using the wrong command then ran into a bound kernel driver error. I then had to blacklist the driver for some reason in order to get the xorg.conf file.
