View Full Version : [ubuntu] Missing xorg.conf file
August 29th, 2010, 08:09 PM
I am running Ubuntu 10.04. I have a dual-head Matrox G450 and I wanted to edit the xorg.conf file that was located (in prior versions) in etc/X11. I don't have an xorg.conf file in that location (or any where else). My question is should I have that file, or has it been re-shuffled in this latest release?
If it has been moved, can anyone tell me where it now resides and what it is called?
If I should have that file, can anyone tell me how to get it back?
I installed OSS for audio. Would that have affected the xorg.conf file?

It's not unusual to not have an xorg.conf file any more - Xorg is pretty good at figuring out the required settings for itself these days, so it's often not needed.
If you do want to create one, it will live in /etc/X11 as before.

And if I create an xorg.conf file, the system will read it?
Cab I put just the pieces I need for the dual head card in the xorg.conf file?

Yes, the xorg.conf will be read automatically if you create it. Not sure about just putting in the bits you need - give it a try and see what happens!
Incidentally, I seem to recall that there's a command somewhere that can dump an xorg.conf file from a current X session. Unfortunately I can't remember the command, but it may help you out if you can find it....

Cool. I am checking my Linux Phrasebook.

you might find help there:

I believe the command is "getconfig" but I have not been able to get this command to work. The system does not recognize it. I searched for it and tried an "apropos" command, but got nothing. Perhaps it has been replaced or I am just not using the command properly. Among other things, I have tried running it from the etc/X11 file.
From the description on the Xorg site, "getconfig" should provide a dump of the current Xsession.
I continue to noodle.

That link was key. Awesomely helpful. I have an edited Xorg.conf file in my X11 directory now. I still have not been able to get the monitors out of mirror mode, but that is probably a defect in my edits to the Xorg.conf file. My edits are based on guessing, based on other posts and old information from the Matrox site. I am hoping that the system is actually reading that Xorg.conf file. This is a process, but getting the xsession dumb was a major step. Thank you.

If you want to be sure that your xorg.conf file is being read, make it invalid in some way - Xorg will complain/refuse to start!
Probably can't help you any more from here. Good luck!
