I'd try to be as short and precise as I can, so here goes all the facts:
- Im running 16.10 (this issue has followed me from 14.04,on the same laptop, and it made me go back to windowsh, so this bad/annoying of a bug it was)
- My laptop is a Sony Vaio VPCEG44FX with upgraded ram (16GB and a 1TB samsung SSD, Nvidia Geforce 440m and a i7 processor(2.45ghz) It is a small beast 5 years old and a warrior I love. (there is nothing wrong on the hardware side I can ASSURE)
- I'm using NVIDIA bINARY 367.35 from Nvidia repo.
- Besides the issue I will now try and describe, there is nothing else that bugs me off Ubuntu, my laptop runs cool now (It was alway burning in windows)
So to the Issue:
Every single time (since 14.04) as the computer boots up, it show the VAIO splash screen, the a Nvidia splash screen (that dims after it is shown) then a short TTY input (something like username-vaioTTY:password) and then I hear the login sound. But the screen is totally black at this point.
I usually proceed to login, but here goes the weird part; usually, and as I've read, you should just up the brightness using FN hotkeys right? well, I cannot do that. I cannot turn up or down the volume, nor turn the brightness up or down. I have to connect an external display, and then the FN key to switch between LCD/External/clone or extend (FN+F7 here) until the external monitor asks for an input (This means Iǘe switched to LCD only mode) and at this point my brightness hotkeys start working.
This very issue made me abandon ubuntu at 14.04, when I started using NVIDIA drivers, so I can guess it's related to them.
Well, fast forward some time and I decided to give Ubuntu another go. installed 16.04 it boots up perfect the first time, then came the dreaded bug. I noticed it just happened after I connected a external display for the first time (first 10 boots approx were fine, as I did not had the need yet for using the other screen) After I connected the screen for the first time, the consequent reboots issued that same bug I described.
I just upgraded to 16.10 Still fighting this. I've tried using legacy drivers, Noveau drivers are out of question for me. (I use tensorflow and other cuda software, needed for my workflow.)
So here I am, a googler and lurker and copypaster asking for your mercy! I usually troubleshoot myself as almost any issue has been asked, but I cannot put my finger on this specific problem.
If any one here would be so kind to pint me in the right direction I'd be oh-so grateful.
BTW, I do not want set brightness scripts, I want my beatiful login screen to show up!! I do not want a semi broken OS.
