Low Screen Resolution

rated 0 times [ 1] [ 0] / answers: 1 / hits: 588 / 2 Years ago, tue, december 14, 2021, 1:28:34

The max I can set my resolution currently is 1024x768, but my laptop's native resolution is 1920x1080. I've always been able to set it to 1920x1080 without issue, but since I broke my video driver (I installed 'nvidia-current' which broke my display, see this thread) I haven't been able to get above the aforementioned 1024x768.

I've tried the instructions from this thread and this wiki but haven't made any progress.

Video Card:

travis@travis-ThinkPad-W510:~$ lscpi |grep VGA

01:00.0 VGA compatible controller: NVIDIA Corporation GT216GLM [Quadro FX 880M] (rev a2)

Output for 'xrandr'

travis@travis-ThinkPad-W510:~$ xrandr

xrandr: Failed to get size of gamma for output default

Screen 0: minimum 640 x 480, current 1024 x 768, maximum 1024 x 768

default connected 1024x768+0+0 0mm x 0mm

    1024x768       61.0*

    800x600        61.0  

    848x480         0.0  

    640x480        60.0

Any suggestions?

Latest NVIDIA GPUs, especially if designed to gaming (like my GTX 750), aren't supported by kernel.

You have to add an external ppa, install the graphic driver and reboot, so type in terminal:

sudo add-apt-repository ppa:mamarley/nvidia -y

sudo apt-get update

sudo apt-get install nvidia-346 nvidia-346-uvm && sudo reboot

The maximum resolution will be automatically used since login screen.

PS I don't reccomend you to install Nvidia driver from the Additional Driver dialog (despite it should be easier), as you can choose only an older version (340.xx), the 346.xx one is not mentioned.
