Retropie setup menu/Runcommand crashing in ES on Ubuntu

mitu

@DjDiabolik said in Retropie setup menu/Runcommand crashing in ES on Ubuntu:

Emulationstation how use current joy2key ? By sudo or not ?

The RetroPie setup (or the other dialog based configuration tools) is using sudo to launch, but not runcommand. Your user needs to be part of the input group, which apparently is not done by default on Ubuntu ?

I'll modify the installation routine to make sure the user is part of the input group, so the 1st error (for runcommand ) does not happen anymore.
EDIT: ok, update RetroPie-Setup and then re-login/reboot, the next run of runcommand (starting a game) should not give you an error.

DjDiabolik

@mitu ok... i have unpdate 'retropie setup script' to last recent commit.... and reboot my ubuntu 24.04.1 LTS

Apparently from terminal nothings it's changed :

From emulationstation i need to test to run one games..... edit in a moment.

DjDiabolik

From emulationstation no works.... it's impossibile to open the "runcommand" option and i have tryed to press many times my controller buttons but not working.
The "runcommand" option it's not open also if i click some keyboard buttons....

mitu

@DjDiabolik Is your user in the input group` ?

DjDiabolik

@mitu said in Retropie setup menu/Runcommand crashing in ES on Ubuntu:

@DjDiabolik Is your user in the input group` ?

How do I find out?

mitu

@DjDiabolik You can run the id command and it should print the list of groups. However, it seems it's not enough on Ubuntu to enable write-access. I'll take a look again to see what options are available.
Thanks for testing.

mitu

Run the following command:

echo 'KERNEL=="uinput", GROUP="input", MODE=0660' | sudo tee /etc/udev/rules.d/80-uinput.rules

and then reboot, afterwards see if the thee permission error still shows up when running as user joy2key_sdl or if runcommand menu works.

DjDiabolik

@mitu

So id output it's this:

diabolik@NUC-Ubuntu:~$ id
uid=1000(diabolik) gid=1000(diabolik) gruppi=1000(diabolik),4(adm),24(cdrom),27(sudo),30(dip),46(plugdev),107(input),122(lpadmin),135(lxd),136(sambashare)
diabolik@NUC-Ubuntu:~$

Before to run the seconds command i have tryed to look on /etc/udev/rules.d

and currently there's no file whit this name:

diabolik@NUC-Ubuntu:/etc/udev/rules.d$ ls
70-snap.canonical-livepatch.rules  70-snap.snapd-desktop-integration.rules  70-snap.snap-store.rules   99-input.rules
70-snap.firefox.rules              70-snap.snapd.rules                      70-snap.thunderbird.rules
diabolik@NUC-Ubuntu:/etc/udev/rules.d$

The echo commands paste this text and create this file.... it's correct ?

DjDiabolik

apparently it's continue to crash... after reboot:

if need i can continue test from here but it's a different hardware.. different username but same os.. also on my brother it's present ubuntu 24.04.1 LTS.

DjDiabolik

anyway... right now "runcommands" option work.... but only if i press button on keyboard.
I can press so many times button on my arcade stick and it's not work.
@mitu

@mitu directly from my brother house. different hardware... same distro ubuntu 24.04.1 LTS and same crash also after last 'retropie setup' commit and reboot system:

The latest update should fix the permissions error. If you still have an error with permissions, check if the /dev/uinput file is writable by the input group by running ls -l /dev/uinput. It should output something like:


pi@retropie$ ls -l /dev/uinput
crw-rw---- 1 root input 10, 223 Oct 16 16:18 /dev/uinput

Also, please don't re-post the same picture/screenshot, it's enough to mention the actual error in your post.

DjDiabolik

@mitu said in Retropie setup menu/Runcommand crashing in ES on Ubuntu:

Also, please don't re-post the same picture/screenshot, it's enough to mention the actual error in your post.

it's not the same screenshot.... that's same exact issue in a totally different hardware. it was also to verify that the exact same problem was present in a different system than the one I use daily at my home.

So... right now i have installed the recent commit on my pc:

It's need to reboot my PC to apply current the new changes?

Simply because the write permission it's different right now:

diabolik@NUC-Ubuntu:~$ ls -l /dev/uinput
crw------- 1 root root 10, 223 ott 17 12:00 /dev/uinput
diabolik@NUC-Ubuntu:~$

if that doesn't work how do I fix the permissions on that file?

Now in that folder i have this file:

diabolik@NUC-Ubuntu:/etc/udev/rules.d$ ls
70-snap.canonical-livepatch.rules  70-snap.snapd-desktop-integration.rules  70-snap.snap-store.rules   80-rpi-uinput.rules  99-input.rules
70-snap.firefox.rules              70-snap.snapd.rules                      70-snap.thunderbird.rules  80-uinput.rules
diabolik@NUC-Ubuntu:/etc/udev/rules.d$

80-uinput.rules it's the file we have created yesterday using echo command.
80-rpi-uinput.rules it's problably created right now from recent commit.

The files are essentially identical in content:

diabolik@NUC-Ubuntu:/etc/udev/rules.d$ cat 80-rpi-uinput.rules
KERNEL=="uinput", MODE="0660", GROUP="input"
diabolik@NUC-Ubuntu:/etc/udev/rules.d$ cat 80-uinput.rules
KERNEL=="uinput", GROUP="input", MODE=0660
diabolik@NUC-Ubuntu:/etc/udev/rules.d$

if i can remove one of the two let me know and possibly i can do it simply with the rm command?

mitu

It's need to reboot my PC to apply current the new changes?

For Ubuntu, it might be needed since uinput is not a module, but a kernel built-in and a reboot may be required for the udev rule to applied.

if i can remove one of the two let me know and possibly i can do it simply with the rm command?

You can remove the 80-uinput.rules file, it's identical to 80-rpi-uinput.rules, which is created by RetroPie-Setup.

ok... now i am watching a movie and i am using pc with kodi...
as soon as I'm done I think I can delete that file with:
sudo rm /etc/udev/rules.d/80-uinput.rules

if I remember it's the file we created yesterday with the command 'echo' exactly?

then I try to restart ubuntu and I rewrite the result of the ls command for uinput in /dev.

thanks in advance for support them.

@mitu

So i have to report this.. after reboot now there's it:

But BAD NEWS is.... runcommand menù not work and not reachable when lauch a games from emulationstation.

I have tryed to open a games... press so many button from my arcade stick and i can't open the runcommand menù from that.

The runcommand option menù can accessible only if i press one button on keyboard and after that, strange, i can move from all voices whit arcade stick.

Ah... running "retropie setup script" from emulationstation continue to crash immediatelly after press one button on keyboard or on arcade stick.

That's a different issue - the one that started this topic. There's a workaround posted by @V0rt3x667 early on.

DjDiabolik

@mitu it's not a big issue on my side because i can run directly retropie setup directly from a terminal as i always did.

at this point it remains only to understand why I can't access the runcommand menu by pressing a button on my arcade stick...

DjDiabolik

@mitu I have a question to ask:
the runcommand window timeout (when a game it's launched), if I'm not mistaken, is 2 seconds.

Isn't that too short a time frame for the joy2key to capture pressure from the arcade stick?

Because also if i launch joy2key from terminal.... It takes almost 4 seconds to add the arcade stick configuration when instead I believe the keyboard is available immediately.

The keyboard is not processed via joy2key, while the joystick is. Looking at the debug log it takes around 2 or 3 sec for joy2key to load the configuration:

However, the load time should be identical to the one from the previous version, so there's nothing new here. You may want to increase the runcommand launch timeout from the configuration if your system is too slow.

EDIT: in contrast, the start-up is almost instant on a Pi4, under 1 sec. Something's fishy with Ubuntu's python-sdl2 combo.
