piuio inconsistent with different builds #9

Closed darknotezero closed 9 years ago

darknotezero commented 9 years ago

hey there,

so i have this hdd image of stepmania that i found that works out of box, running SM 5.0 beta 1. i'm attempting to update to the most recent version of stepmania to take advantage of the simply love theme and also stay current.

when i grabbed the new version of piuio, i encountered the same error that now in the "closed ticket" area where you said that the kernel and/or Linux version is too old and the legacy piuio should be used instead.

the thing is, the legacy version of piuio is already running on the machine - if i try to run one of the two sm builds installed in the machine running the SM 5.0 beta 1, pads work with no issues, but if i try to run the version I installed, 5.0.7, piuio is not recognized as a source during test input, so the pads are not responsive at all.

any clue on the issue here? should I try to remake the legacy piuio build and scratch the one that's there, or is that a waste of time? is there something else I'm missing?

many thanks for your work on this!

Could be a lot of things. If you're going to be upgrading kernel drivers, you should make sure to have some knowledge about your distro, packages, kernel, and how modules work. Random HDD images for easy-to-install open-source software are usually more miss than hit. If you still want to go that route, some troubleshooting questions:

Yeah, my knowledge of Linux prior to starting this project was pretty much nil (although i'm a hack computer programmer), so i know i'm basically running around blind. That's part of why i'm doing this, because i want to learn more about it, learn more about even what questions i should be asking myself when faced with issues.

I don't know how to answer all of those questions, but i can answer a few:

The big question to answer is the last one - The InputDrivers in the preferences.ini file was set to nothing - I thought that that was fine since the preinstalled SMs worked fine under that configuration. Yesterday I actually decided to try to forcefeed the issue by putting "PIUIO" as the InputDriver and the LightsDriver, and lo and behold the pads worked (although it made the QWERTY keyboard stop working).

So now i have it essentially functioning the way that i want to, but I kind of feel the need to update the kernel to something more current because i get the impression that Mint 13 is pretty old and i want to stay current and maybe try to get the new PIUIO driver to compile and then load it in. Even if i break something, i can always fall back on the original HDD and start over, and particularly start over with new knowledge. I don't know if that's a sound plan or if it's plain stupid. :)

i'll find some of the other answers to your questions for completion - for myself more than anything else because i need and want to learn more about linux than i currently do.

It may be worth noting that using

InputDrivers=PIUIO

in your StepMania.ini only worked with the 0.1 release of this driver. From 0.2 on, you should use

InputDrivers=LinuxEvent,x11 
LightsDriver=Linux_PIUIO_Leds

to support input and lights.
