For many years I had this same desktop setup with an Nvidia GTX 1060 card and two monitors. Usually I run with just the one primary monitor but sometimes I connect the second monitor using "TwinView" which is Nvidia's way of extending the desktop to the second monitor (as opposed to screen mirroring). I just updated this system to Xubuntu 22.10 and using Mame 0.250 and I get some X Error now. Xubuntu is still using X11 not Wayland, so I don't know if that has anything to do with it since this used to just work flawlessly for many years. Any help would be appreciated.

X Error of failed request: BadRRCrtc (invalid Crtc parameter)
Major opcode of failed request: 140 (RANDR)
Minor opcode of failed request: 20 (RRGetCrtcInfo)
Crtc id in failed request: 0x0
Serial number of failed request: 243
Current serial number in output stream: 243

Below is the full output. I also tried with -noreadconfig and get the same result.

You might try the "-resolution" parameter or even just open in "-window" windowed mode. -resolution preferred resolution for all screens; format is <width>x<height>[@<refreshrate>] or 'auto' -resolution0 preferred resolution of the first screen; format is <width>x<height>[@<refreshrate>] or 'auto' -resolution1 preferred resolution of the second screen; format is <width>x<height>[@<refreshrate>] or 'auto' -resolution2 preferred resolution of the third screen; format is <width>x<height>[@<refreshrate>] or 'auto' -resolution3 preferred resolution of the fourth screen; format is <width>x<height>[@<refreshrate>] or 'auto' -switchres enable resolution switching ./mame -showusage \| grep maximize -maximize default to maximized windows

X Error of failed request: GLXBadDrawable Major opcode of failed request: 151 (GLX) Minor opcode of failed request: 11 (X_GLXSwapBuffers) Serial number of failed request: 425 Current serial number in output stream: 427 I can start mame with -window and specify the screen and the mame window appears on the screen I tell it, but if I do Alt-Enter during emulation I still get the same error. X Error of failed request: BadRRCrtc (invalid Crtc parameter) Major opcode of failed request: 140 (RANDR) Minor opcode of failed request: 20 (RRGetCrtcInfo) Crtc id in failed request: 0x0 Serial number of failed request: 479 Current serial number in output stream: 479

(One app that's pretty useful is arandr even though you have the display settings in xubuntu) You could try specifying the resolution to switch to, does TwinView treat both screens as one big monitor screen? Maybe -resolution 3840x1080 In the mame log it seems to think there's two screens, maybe try -numscreens 2? What does xrandr report? xrandr --verbose gives you even more info. You might even try using -video bgfx -bgfx_backend opengl or -video vulkan

There's was new environment variable that I wasn't aware of export SDL_VIDEO_X11_XRANDR=0 I need to set that in order to specify the screen. Actually, if this is set, then I don't even need to use "-screen screen", mame will just start the display on whatever monitor the variable is set to, 0 or 1. Some SDL environment variables that I used in the past were these ones: SDL_WINDOW_FULLSCREEN_DESKTOP= SDL_VIDEO_FULLSCREEN_HEAD= SDL_WINDOW_FULLSCREEN= SDL_VIDEO_FULLSCREEN_DISPLAY=** But I don't think these seem to do anything anymore. I'll have to do more experimenting. I have SDL 2.24.0 on Xubuntu 22.10.
