I'm having issues with my display resolution in Pop OS!

[IdidAthing]

After installing Pop OS! it installed most of my drivers perfectly fine, the thing is that my aux jack isn't working as well as my display (which works but can only show in 720p or 1080p)

 

1.     I can't figure out how to find a driver menu/ device list and how to fix it so that my aux jack works.

2.     I don't know if it's a display driver issue or if I need to open up a new thread, my display is an Onyx Boox Lumi, It works in windows, I can't use the specific resolution, but I can find the right aspect ratio, (the Boox Lumi's resolution is 2200 x 1650) however in Pop OS! it only gives me the option of using 720p or 1080p which leaves black bars at the top and bottom of the display (which is only 13.3in)

Specs? Your audio device and GPU are very important for figuring this out. 

 

That said, for the display, you can try setting a custom resolution with xrandr (given your using the X11 version of Cosmic, not Wayland).

xrandr -s 2200x1650

 

As for finding the audio devices, run this command to find the audio device

lspci | grep Audio

#If this does not return an output, just run
lspci

The display command didn't work and below is a picture of the error it gave (for the display command) as well as the specs it gave when I ran "lspci | grep Audio"

Just to let you know my Computer is an Alienware 15 R2 with a i7 6700HQ, 16GB Ram, and a Nvidia 980m (I didn't now if those mattered)

(Also, you didn't mention how to see what drivers are installed and where to go to install them)

OK, so you'll need to set a custom mode. This tutorial gives you most of what you need in order to set it up

https://askubuntu.com/questions/377937/how-do-i-set-a-custom-resolution

 

That said, you will need to run this command 

xrandr -q

to identify what port your monitor is connected to and replace "VGA-0" with whatever that is

I tried the commands given in the link for both resolutions (except for where does "xrandr -q" go?) and it error out for both of them.

For the second one you mistyped the resolution. You typed "2200x1650_00" instead of "2200x1650_60.00"

 

No idea why the first one isn't working though.

I fixed what I typed and it still failed. It had the same error code that the first picture showed

OK, that's the way I know how to do it. According to someone on the Arch Linux forums, there is a way to get it working with nvidia-settings.

Hope that works because I'm running out of ideas.

The first one should have run. If he runs xrandr again he should see an unassigned 2200x1650_60.00 entry now. He mistyped the 60.00 but also didn't have quotes around it.

try:

xrandr --addmode HDMI-0 "2200x1650_60.00"

you should notice a screen update. you still won't be in 2200x1650 but if it worked the screen will refresh at that point right clicking desktop and going to display settings you should see it in the drop down.

 

If it isn't there run xrandr again and post.

If I just type in xrandr it doesn’t show the resolution, but if I type in xrandr -q it shows up in a different section at the very bottom. Do you think I should try the nvidia settings, if so any clue how?

Yeah you should be good to go to desktop settings now and choose the 2200x1650 option from the resolution drop down.

Well... It shows up in the drop down for my laptop display, but not for my external one.

I'm mirror the two displays, don't know if that's a problem.

So, it didn't add the option to my external display.

Here are pics of the settings

IDK if it matters but I just checked my display refresh rate and it is 38.6 hz

That's probably at least part of the problem. You should've done HDMI-0 like you were doing before. See if redoing those commands with HDMI-0 will solve your problem.

Try going down to 30Hz or even 25Hz and see if that fixes it. What you're doing should be working.

I'm still working on it, I'll try and post again tomorrow

I was able to get the display to work, but I still have a few issues that I think I'll need help with.

I'll first state how I did it and after that I will post the issues I am still having

*before trying to change any of these settings set up a system restore point, so if you mess up a display setting you can revert back to your previous system image

 

__________________________________________________________________________________________________________________

My monitor specs are that it is 2200x1650 and it has a refresh rate of 38.60HZ (the monitor is a Boox Max Lumi)

How I did it

I switched to display only on external monitor and then I had to go into the NVIDIA X Server Settings and then go into the section called X Server Display Configuration and I clicked advanced

 

 

 

 

 

Then I moved the slider where it says "Underscan" to the right and moved back to the left  it changed the resolution it showed on that layout rectangle that says "Toshiba-UH2D" from 3072x1728 to 1920x1080

 

 

 

 

 

 

Next I clicked revert and now we can see the what the default settings are. You will notice for the following settings that the resolution of ViewPortIn and Panning are 60% larger than the actual resolution 

Also on the ViewPortOut line there are two numbers with each with a + (plus sign) preceding on the nubmer

I don't know why those numbers are there but they determine if the Resolution will work or not. If their value is not correct then the resolution won't work.

You can also see that the Resolutions of ViewPortIn and Panning are identical.

 

 

 

 

 

 

 

Then I figured out that those two numbers at the end can be determined by moving the slider around in basic view, so I click back into basic view. I then figured out that the first of the number next to a + corresponds to the width (in the default setting's case 1920) and the second number next to a + corresponds to the height (in the default settings case 1080)

I also figured out that when moving the slider back and for to determine the value it didn't matter if it was the height or the width I was looking at, it was the value that mattered. So for example in the below image I slid the slider to the resolution of 1440x810, the number 1440 was what I was looking for (because one of the available display resolutions for my monitor is 1440x1080)

 

 

I then switched back into advanced and I saw that the first number next to a + on the ViewPortOut row gave a value of 240. So now I know that 1440 pairs with 240

 

 

 

I then clicked revert and it went back to the default configuration and I stayed in the advanced tab here I could see that for 1920 and 1080 the number next to a + is 0. So then I was ready to move onto the next step.

 

 

 

I'll make another post in order to continue the instructions

I then calculated what 60% more than a resolution of 1440x1080 is and I determined it was 2304x1728 and that the numbers next to a + are 240 and 0 (240 corresponds with 1440 and 0 corresponds with 1080

I then inputted

ViewPortIn:    2304x1728

ViewPortOut: 1440x1080+240+0

Panning:        2304x1728

 

This however did then lead me into an issue of my dpi being too large and I didn't know how to change it

 

 

 

 

So the I changed it so that the resolution of the ViewPortIn, ViewPortOut, and Panning matched and it made it so my dpi seems okay.

 

 

 

I then switched so that I was in multimonitor mode and it worked fine, but when I switched to mirror mode (which is the one I use most often) it had a weird overhang part. I could see the navigation buttons and everything fine on my external monitor (4:3 aspect ration). But, my laptop monitor had a area where the windows could go off into and I couldn't see them on my external display pictured in the images below

 

 

 

 

 

 

 

 

in the next post I'll explain more of the issues I'm having

[IdidAthing]

The Issues I'm still having

• I can't fix Mirror mode (I want it to be like it is on windows where on the 4:3 display it looks normal and then on the 16:9 display it has black bars on the left and right and the mirrored 4:3 display is in the middle
• I can't get a Higher Resolution to work for example I tried 1920x1440 and it didn't work, even though I had the ViewportOut set as "1920x1440+0+240"
• I can't Change DPI
• I don't know how to get it to save the monitor settings I set in NVIDA (it resets upon reboot)
• The new Display settings don't show up in the Pop OS! settings menu (so, it doesn't give me a correct resolution to choose from and I can't change my DPI
