Edit: The problem was lightdm, not related to GPU driver issues at all.
Hope someone can help. This is the first optimus install I’ve done, and the first UEFI install I’ve done. (My current other laptop is 2nd gen Sandybridge w/nvidia gtx460m, but optimus is HW disabled on the motherboard, so I"ve never had to worry about it before.)
Long story short - I booted the liveusb with bios set to “legacy boot” and “hybrid graphics”. I actually don’t care at all about the switchable graphics. I’ll get it working if I can, but I’m very happy to use nvidia only.
However, counterintuitively, if I choose “discrete only” in the bios, I can’t boot to the live environment no matter what I’ve tried. (And I did spend quite awhile trying.)
With the settings as noted above, I was able to boot to the live environment and install Antergos, only with adding “modprobe.blacklist=nouveau” to the kernel line.
On first boot after install, lightdm failed to load.
Well, I haven’t documented what I did very well, but suffice to say that I have combed google, the Antergos wiki, and the arch wiki to try and understand how to get this thing to boot. The problem appears to be lightdm failing every single time.
I have undone all the xorg conf and etc that I did along the way, however I did pacman -S nvidia - and that is still installed.
Confounding me further - I tried booting into the live environment again while typing this, and now that’s not working either.
I don’t seem to be finding a lot of reports of problems installing linux with this laptop, but perhaps my google skills are just super weak?
While I’m not actually a noob, I AM entirely one with regard to having to worry about these hybrid graphics issues - so if someone could give me a little handholding, I’d certainly appreciate it.
I’d like to try and fix the current install if possible, but if I can get the live environment to boot again, I’m happy to start fresh.
