USB C to DP external monitor Asus tuf 15 laptop and Asus TUF gaming monitor <SOLVED>

You are right, I reset the laptop and now the USB C doesn't work, it gives a hint, the external monitor wakes up, but then go back to sleep, before it didn't even get there.

HDMI still work on demand.

If I change to on demand while on USB-C monitor, then a log out and log in, it does work.

This is getting confusing. If the laptop is powered on with the monitor connected to the USB-C port and set to On-Demand mode, then the monitor does not work. But after getting to the desktop, if you then log out and back in, then it starts working?

If that is true, then repeat those steps. When you get to the desktop, get the output of inxi -Gx.
Then log out and back in and get the output of inxi -Gx again.

I can't make it work by loging out and then in, might have been another flow that confused me.

So it appears you will need to use the HDMI connection to use On-Demand mode. Usually that port is connected to the Nvidia GPU but on your hardware it’s not, so I want to check if On-Demand mode is working correctly. Use these commands and post the output:

Code: Select all

glxinfo | grep renderer
nvidia-optimus-offload-glx glxinfo | grep renderer

On-Demand mode is working correctly.

But not for the USB C tho, how can we make it work? the idea of on demand is that when I connect the external monitor it should start using nvidia and when I unplug it, should start using AMD

The On-Demand feature does not work that way. It’s purpose is to be able to select the more powerful GPU to do the graphics rendering (processing) where it is needed (there is a demand) for a certain app, while the rest of the desktop rendering is done by the weaker power-saving GPU. This process must be initiated in Linux by using the command:
nvidia-optimus-offload-glx <name-of-app>.

This was done when you previously used the command:
nvidia-optimus-offload-glx glxinfo | grep renderer

Alternately, if using Cinnamon, this can be done by right clicking on an app in the menu. There should be an option: Run with Nvidia GPU. Do you see this option?

So you don’t need to use the USB-C connection, which is not as reliable as the HDMI connection.

I frequently read hardware related topics in the Mint, Ubuntu, Arch and Nvidia Developer forums, but I have not seen On-Demand mode work with a USB-C connection at this time.

I see, the good thing about using USB-C is that you can get 165hz refresh rate in the second screen, that is why I use it. In windows, when I am using only the laptp monitor, the nvidia card is off, but turned on when using demanding programs. If I connect the USB-C monitor, then it starts using the nvidia to power it.

How can I creat that behaviour in linux? it is the only thing I am missing to change for good.

I wanted to be sure about this question I asked in my previous post:
If you right click on an app in the menu, is there an option: Run with Nvidia GPU

With the monitor connected to the HDMI port, post the output of xrandr

The monitor is using a 144 Hz refresh rate now. Is there that much difference in performance between that rate and 165?

Try using these 3 commands to force a 165 Hz rate:

Code: Select all

xrandr --newmode "2560x1440_165"  639.74  2560 2568 2600 2640  1440 1456 1464 1470 +hsync -vsync    
xrandr --addmode HDMI-A-0 2560x1440_165   
xrandr --output HDMI-A-0 --mode 2560x1440_165

If that doesn’t work, then use this command first:

Code: Select all

xrandr --output HDMI-A-0 --set "max bpc" 8

Then try the other 3 xrandr commands again.

If that fails, then post the output of xrandr --verbose

HDMI version 2.0 supports up to a 600 MHz dot clock (pixel clock) frequency. The info from the EDID, using an HDMI connection lists this:

Monitor ranges (GTF): 48-144Hz V, 30-222kHz H, max dotclock 600MHz

But using a 2560x1440 resolution at 165 Hz refresh rate requires a 639.74 dot clock:

2560x1440 (0x1de) 639.740MHz +HSync -VSync +preferred
h: width 2560 start 2568 end 2600 total 2640 skew 0 clock 242.33KHz
v: height 1440 start 1456 end 1464 total 1470 clock 164.85Hz

Here is the info from the EDID using a DP connection:

Monitor ranges (bare limits): 48-165Hz V, 250-250kHz H, max dotclock 650MHz

Were you able to get a refresh rate of 165 in Windows using an HDMI connection?

MahaRav · Post by **MahaRav** » Tue Oct 19, 2021 1:58 pm

Exactly, that is why I use the USB - C to DP, because USB - C does give what the monitor needs to run in 165hz. The HDMI gives up to 144hz in windows too.

There is nothing else to test. From other topics that I’ve read, most other users report they can’t tell much difference between using a 144 vs 165 Hz refresh rate.

If the laptop is going to stay in one location most of the time, then I suggest connecting the cables to both the HDMI and USB-C ports and leaving them connected. That way all you need to do is switch from On-Demand to Performance mode when needed.

Got it, thanks so much for your help.

How can I check if when on demand I right click an dchoose to run with nvidia, it is actually rendering with nvidia?
