steam-devices VS libinput-config

if you mean this ( https://github.com/ValveSoftware/steam-devices/blob/master/60-steam-input.rules ) in /etc/udev/rules.d , yes i did

Create an udev rule for the device, you can copy the rule for your device from here.

I am attempting to play Spelunky with a controller but I am not having any luck. Spelunky has a platinum rating on protondb and runs as expected. I am in a flatpak and I did install the udev rules from valve if any of that makes a difference. My controller works fine in native games.

I solved the problem by copying the 60-steam-input.rules file to the folder: /etc/udev/rules.d

this is their Github: https://github.com/ValveSoftware/steam-devices

steam maintains udev rules for controllers that might help: https://github.com/ValveSoftware/steam-devices/blob/master/60-steam-input.rules

Here is my open PR for the hori alpha for reference: https://github.com/ValveSoftware/steam-devices/pull/42/files

To use a controller with the Steam flatpak, you need to layer the steam-devices package from RPM Fusion, or download the udev rules from upstream and install them to /etc/udev/rules.d/ (which is what I did).

> The effort you need to go through to actually use these depends on how your distribution handles the file permissions of /dev/uinput. Some of them have it as root:input, in which case you just need to usermod -a -G input and then relog to get it working. Others have it as root:root so you either need to go do some reconfigurations to change its permissions or live with running the software using it as root.

There's a trick to that. The TL;DR is "install the steam-devices package or similar" (https://github.com/ValveSoftware/steam-devices/), which adds the following udev rule (and others, but this is the relevant one):

  # Steam Controller udev write access

There is https://gitlab.com/warningnonpotablewater/libinput-config which injects itself into the compositor process and then modifies libinput according to a config file, it gives back some control.

1st option: https://gitlab.com/warningnonpotablewater/libinput-config

Dude, I had the same issue, try https://gitlab.com/warningnonpotablewater/libinput-config. Literally one setting, "scroll-factor" I believe. Still, that is sorta like workaround

If you're ok with an LD_PRELOAD hack and a replacement of libinput, you could try libinput-config.

My laptop touchpad have a weird problem with gnome where vertical scrolling is too much sensitive. For a long time i've been using https://gitlab.com/warningnonpotablewater/libinput-config to change the scroll-factor-y=0.25 to fix this problem. But i think it uses some hacky method where using LD_PRELOAD variable to do some trick. The problem with this is with some sandboxing issues where if i use a flatpak version of a terminal it will throw "ERROR: ld.so: object '/usr/local/lib/libinput-config.so' from /etc/ld.so.preload cannot be preloaded (cannot open shared object file)" when started. I thought the issue with sensitivity in gnome is due to a bug in gtk3 as discussed in https://gitlab.gnome.org/GNOME/gtk/-/issues/1308 this issue. I also thought this is the case because i didn't have this scrolling issue on gnome settings window (which i think now uses gtk4). But firefox and chromium definitely had the scrolling problem and I think they both written in gtk3 . but today i tried KDE after a long time and I found that there settings panel have a option to change the vertical scrolling distance and changing that fixes the problem system wide including firefox and chromium. So is there any possibility that gnome could also implemet such feature to change scroll sensitivity from there settings panel to fix the wired issue with gtk3 apps.

Whow thanks, these Firefox changes are perfect, the scrolling with the touchpad is Firefox much more pleasant and mouse wheel scrolling stays the same (which is a good thing) on default F37. Thanks for sharing this! I also tried https://gitlab.com/warningnonpotablewater/libinput-config but ended op getting small weird crashes in gnome (/gnome/shell i believe), not 100% sure they are related but I noticed some crashes after installing.

I fixed it by installing this: https://gitlab.com/warningnonpotablewater/libinput-config

libinput config i installed this and set accel-profile=flat in the config file but im not convinced i installed it correctly as it did nothing. and the config file started out empty. i was using nano to edit it. (maybe nano just created the config file the first time it tried to "edit" it?)

Unfortunately there is no extension capable of exposing missing libinput settings ... so I use https://gitlab.com/warningnonpotablewater/libinput-config

I've tried using libinput-config made by warningnonpotablewater but it doesn't seem to have an effect.
