Awesome WM 4.x screen geometry issues

I have finally decided to plunge into my awesome wm config, and update it to the 4.x specs. The original update to the config (rc.lua) was for my main laptop, and works as advertised, no issues. I then took the same config, and installed on another desktop I have, which has an nvidia graphics card (NVIDIA Corporation GT218 [GeForce 210] (rev a2)). The only issue I have is that the screen is being cut off to the right and the bottom, almost like awesome is not respecting my xorg.conf config for my nvidia card; I deleted the rc.lua I transferred, and reverted to the stock rc.lua shipped with awesome wm 4.0/4.1, however the issue persists.

Here is my xorg.conf file for the nvidia card:

I have a feeling this is purely about the overscan settings I have set (my 54 inch doesn't have proper overscan settings), however I can not be certain about this. Let me know if I need to paste more information.

Re: Awesome WM 4.x screen geometry issues

It took me quite a while but I figured out that a the screen:fake_resize command does the trick:
https://awesomewm.org/doc/api/classes/s … n:fake_add

So I have added the following two lines into my rc.lua file:

screen[1]:fake_resize(0, 0, 1920, 1080)
screen[2]:fake_resize(1920, 0, 1820, 1026)

So my left screen has no underscan but the second on the right is a TV with underscan from 1920x1080 to 1820x1026. Of course I have adjusted my nvidia-settings accordingly.

Hope it helps even after some years between the question and an answer.
