      I have a pi4 that has been running flawlessly but wanted to play steam and ps2 games so I just got an i5 4th gen Lenovo m93p. Everything was working great over vga and then I installed 1650 low profile graphics card. The Nvidia drivers screwed up Ubuntu totally but I got that figured out. Steam and pcsx2 are running great but now Emulationstation only has one output resolution and it is very low. If i try to change the resolution (after pressing a button while loading a rom) it just reloads the screen I was just on... I know there is a config file somewhere I should probably edit but I can’t locate it in the system.

      Anyone know where that file is or just what I should do?!

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

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

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

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

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

                        @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

                          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

                              @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!

                                        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.

                                            Where exactly did you add the changes ?
