Ubuntu 14.04 stuck at 640x480 resolution

I have recently purchased в system, i7 6700, z170 mobo, Nvidia 980 Ты and so on. I set it up for dualboot: win10 и ubuntu 14.04. Although I know my way around в computer, I am not родственник with ubuntu at all except for в few commands years ago.

The goal is to использовал this system for simulations и learning algorithms, including deep learning. For the latter I require nvidia драйверы, cuda and possibly also bumblebee.

Unfortunately, I am currently stuck where my screen resolution is limited to 640x480. I have tried and searched everywhere, including сходный questions, but unsuccesful.

This list sums it up:

• ПК is connected to телевизор through HDMI
• installed nvidia 352.38 at first, resolution worked умер
• after bumblebee install I got black screen at restart.
• through restoresession I got back in, but am now stuck at 640x480 "Буильт-ин Дисплаи".
• integrated GPU - been blacklisted, so I suspect it is running at the nvidia GPU.

Things tried:

• installed и tried nvidia 352 and 358 (tried to solve issue by updating to не avail)
• nvidia-settings хан be run, but it существуешь не filled in options и cannot find registry key file
• xorg.conf changed, adopted, переместите but не success.
• attempted дополнительный modes through xrandr. Although resolutions have been added, they could not be selected. Xrandr repeatedly claims 'failed to get size of гамма for output default'
• changed kernel through grub: i915.preliminary_hw_support = 1, не effect
• nvidia-xconfig command was not found, but I could find it on my ПК:/usr/lib/nvidia-358/bin/nvidia-xconfig. I ran and got в xorg.conf but it did not have any effect, nor after I modified it with дополнительный screen resolutions.

Currently, I am at в loss and could really использовал some help to get this ubuntu on track! I will really appreciate any help! Cheers, AIworks
