I have recently purchased a system, i7 6700, z170 mobo, Nvidia 980 Ti and so on. I set it up for dualboot: win10 & ubuntu 14.04. Although I know my way around a computer, I am not familiar with ubuntu at all except for a few commands years ago.
The goal is to use this system for simulations & learning algorithms, including deep learning. For the latter I require nvidia drivers, 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 similar questions, but unsuccesful.
This list sums it up:
- PC is connected to TV through HDMI
- installed nvidia 352.38 at first, resolution worked fine
- after bumblebee install I got black screen at restart.
- through restoresession I got back in, but am now stuck at 640x480 "Built-in Display".
- integrated GPU has been blacklisted, so I suspect it is running at the nvidia GPU.
Things tried:
- installed & tried nvidia 352 and 358 (tried to solve issue by updating to no avail)
- nvidia-settings can be run, but it has no filled in options & cannot find registry key file
- xorg.conf changed, adopted, removed but no success.
- attempted extra modes through xrandr. Although resolutions have been added, they could not be selected. Xrandr repeatedly claims 'failed to get size of gamma for output default'
- changed kernel through grub: i915.preliminary_hw_support = 1, no effect
- nvidia-xconfig command was not found, but I could find it on my PC: /usr/lib/nvidia-358/bin/nvidia-xconfig. I ran and got a xorg.conf but it did not have any effect, nor after I modified it with extra screen resolutions.
Currently, I am at a loss and could really use some help to get this ubuntu on track! I will really appreciate any help! Cheers, AIworks
