Problem booting with two mnitors

theduesta · 2015-01-31 19:48:34

Basically my problem is that if I boot my machine with both of my monitors plugged in, after the bios screen both lose signal and nothing happens. If only one is plugged in everything works fine and after boot I am able to plug in the second monitor and restart X to have full dual monitor functionality.

I'm using a Nvidia card with the open source drivers and I believe that the problem is KMS related as disabling early KMS caused both screens to have some console output before losing signal.

Thanks for any help in advance.

Is there a setting in the bios to give preference to one monitor over the other?

Just checked and didn't notice anything like that, the bios screen defaults HDMI port though, guess I should mention that one is plugged in with HDMI and the other with DVI.

So what options do you have there? Would it possibly be HDMI and VGA or onboard or something? If one setting is causing the issue, then perhaps the other will fix it. It may mean that your DVI monitor would be the one that is posted to, which can get annoying if you are used to the other one, but if it boots alright....
