I'm pulling my hair over this, I am experimenting with multi monitor, starting with 2 but eventually want to try 3 (can't find much resources on getting this to work, but will just bite the bullet and buy a video card with 3 proper outputs and try it). I want the centre one to be primary, not the most left one, which is the default.
I found that this command can set the primary:
Problem is, anything command line like that does not stick. I tried everything, such as putting it in /etc/rc/local (which does not even seem to execute at all) and various X related scripts, and nothing works. How do I get this setting to stick? I also want it to be for all users. I only have 1 user account but if I setup another I don't want to have to do it all over again.
Thanks in advance.
