I'm on Fedora 6.3. After a reboot, some proprietary software didn't want to run. I found out that the startup script for said software manually sets DISPLAY to :0.0, which I know is not a good idea, and I can fix.
I'd thought that :0.0 was the norm.
It is, but it's not a hard and fast rule. If you are running multiple local X consoles, for example, they can't all be :0.0. I've also seen different identifiers when one X session is hung and/or doesn't finish cleanly before a new one is brought up.
If DISPLAY is consistently set to :3.0, perhaps it is a Fedora-specific thing, and it'd be best to ask people more familiar with Fedora. If they have made changes, those changes may not have propagated to RHEL/ CentOS yet.
Sorry, brain fart, I'm running CentOS 6.3, not Fedora. The weird thing is that this changed after a reboot. I haven't done any updates that seem relevant lately either.
And yes, I know :0.0 shouldn't be depended on, but it seems weird that it'd change like that for no good reason.
