Low resolution/no options in Ubuntu

mitu

Did you disable the integrated GPU after installing the Nvidia card ?

Shadycommaslim

@mitu nope! How do I do that?

mitu

@Shadycommaslim It's usually done from the BIOS, if possible.

Shadycommaslim

@mitu awesome! I’ll give it a try

Shadycommaslim

@mitu alrighty I selected pcie graphics instead auto in the bios but it didn’t fix anything unfortunately

mitu

@Shadycommaslim What resolutions show as being supported on your GPU ? What is your current desktop resolution ?

Shadycommaslim

@mitu in Ubuntu setting it has 6 options ranging from 800x600 to 1920x1080. I’m set on the 1920x1080

mitu

Then EmulationStation must be running at 1920x1080 - isn't that ok ? Do you think it runs in another resolution ?

Shadycommaslim

@mitu ah yes sorry perhaps I see how I was unclear in my problem description. EmulationStation is in 1080 but I guess retroarch is stuck super low. When you load any game you press a button to change which emulator/settings and when you try and change resolution here it reloads the current screen instead of going to the next one where I used to be able to change resolution

mitu

I see, so the listing of available video modes in the Runcommand launch menu doesn't work. This is something that's been recently added, so it didn't get a lot of usage.
Can you run the following command and then post the output on pastebin.com ?

xrandr --verbose

Shadycommaslim

@mitu no problem!

@mitu worth noting it worked fine before installing video card... now if I ever end up in the login screen it still cause Ubuntu to freeze or get stuck in a loop. I removed “splash” from the grub to fix this problem initially. When I’m at the screen we’re talking about it’s a purple background instead of my desktop background which seems weird.

Also... just noticed when the runcommand screen reloads it says this in the corner:

sed: -e Expression #1, char 51: unterminated ‘s’ command

(That’s for the +rom version. For default video mode it’s the same except char 29)

It's not weird, it's the default gnome-terminal background in Ubuntu. Since runcommand runs in the terminal, you see this probably for the error in runcommand.

@mitu gotcha. Thanks for your help and patience. Rasp pi and this are my only Linux experiences so far!

mitu

Which Ubuntu version are you using ?

Shadycommaslim

@mitu 20.04 lts

mitu

I think I may have found the culprit, but I'll tag @psyke83 since the new X11 runcommand video mode selection is his expertise.
I think the matching for the xrandr XID mode is not taking into account it's a hexcode, for the xrandr output in this topic, no video mode is detected. Seems to work with this change.

Shadycommaslim

Hmm I made those changes and still getting the same problem, unfortunately.

Where exactly did you add the changes ?

Shadycommaslim

@mitu haha yeah it’s possible I did it incorrectly. Found the runcommand.sh file in RetroPie-Setup/scriptmodules/supplementary/runcommand
