fbset: command not found - No framebuffer device?

vbs

I am on x86 using Ubuntu 16.04 with latest Retropie.

Every now and then when starting something I get an error saying something like "runcommand.sh: Line 5xx: fbset: command not found". For example it happens when starting mupen64plus. The emulator still starts and seems to work but I guess it tried to configure the screen resolution of the framebuffer device which failed.

I went and installed fbset using apt. But then when starting fbset manually it says (same when starting mupen):
vbs@vbs-XS35:~$ fbset
open /dev/fb0: No such file or directory

So it seems I don't have a framebuffer device at all. I am kinda stuck there, anything I can do?

Thank you guys!

it shouldn't be trying to call that on X86/X11 - you can ignore it as it's harmless, but it shouldn't call it anymore.

Do you know which exact line ? Did you copy any configs from a previous install on a Raspberry Pi ?

Ahh ok, thanks! The message appears twice when starting mupen. Once on line 542 and once on 543.

No, I didn't copy from Raspberry but I sometimes tend to try stuff here and there so I cannot guarantee that I didn't cause it in the end. But I usually try to only touch stuff I think I understand :)

I'll check in mupen launch code. Thanks for the feedback

it also happens with other emulations, like for example intellevision (btw, for me it starts as windowed mode in x86/ubuntu)
Best wishes,

Please can you post me the output of grep -a4 "(fbset)" /opt/retropie/supplementary/runcommand/runcommand.sh

Aha - did you set the framebuffer res in the runcommand menu ? That won't work on X - it shouldn't show - but you should not use it as it won't do anything.

I have now disabled the framebuffer menus and made it ignore any previously saved configs for this (as it isn't relevant when running on X) - if you update the RetroPie setup script from the RetroPie-Setup gui it should update.

No problem:

vbs@vbs-XS35:~$  grep -a4 "(fbset)" /opt/retropie/supplementary/runcommand/runcommand.sh
# get default fb_res (if not running on X)
fb_orig=""
if [[ -z "$DISPLAY" ]]; then
    fb_orig="$(fbset)"
    fb_orig="${fb_orig##*mode \"}"
    fb_orig="${fb_orig%%\"*}"
fi

Well, I probably clicked that option in the runcommand menu "Select framebuffer Res" but I think I chose "320x240" which was the initially value anyway. But ok, that might be the reason! Thanks!
