My problem is as follows: I have recently installed a fresh copy of Ubuntu 12.04 LTS, and upon booting, the DisplayPort monitor loses signal immediatedly after the Ubuntu splash screen.
A brief history of what I've done and tried:
- I installed Ubuntu, allowing the OS to download updates while installing, and my monitor lost signal immediately after splash the first time I booted.
- I re-installed Ubuntu not allowing the OS to download updates, and my computer booted through splash screen successfully.
- I updated the nVidia drivers, selecting "nvidia-current" and then rebooted. I was again met with no signal immediately after splash.
- I tried editing the boot command in grub by adding "nomodeset", disabling splash, etc. and experienced no change; the monitor still received no signal.
- I tried various versions of the nvidia drivers and experienced no change.
- I FINALLY tried removing my DisplayPort cable, instead connecting the monitor via HDMI. I have signal just fine!
Once I log in with HDMI connected, I can swap the cables for DisplayPort and I receive signal just fine as well. I just can't boot with DisplayPort connected.
Some background about my relevant (and maybe some irrelevant) hardware:
- Motherboard: Asus Maximus V Gene
- GPU: EVGA GeForce 660 Ti
- Monitor: Dell S2340T
I'm still relatively inexperienced with Linux, so I'm not sure what to try to get DisplayPort working through boot. Any suggestions would be much appreciated!
