I was literally picking my nose when I saw this! 😭

Can’t do it with random apps, but most FOSS apps, like Molly (fork of Signal), Element (matrix protocol), Tusky (for Mastodon), etc. use this.

I think using it for discord can be possible, but you would have to set up your own notification server. Like for Signal chats, there has to be another server between my notification server and Signal’s server (MollySocket), which listens to the notifications and sends it to my Ntfy. You will have to set something up that is always online waiting for new messages, and when new message arrives, it pings your Ntfy, and Ntfy pings your phone.

Ntfy exists. I use it for 3-4 apps.

I have a cheap controller that has 2 modes, xinput and dinput, which automatically gets selected. If I plug it into a Windows PC it gets detected as X input and the controller shows a blue light and everything works including the rumble motors and pressure sensitive triggers. If I connect it to a Linux PC or any Android device via an OTG or if I connect that dongle directly into my Android TV, the controller shows a purple light and it gets detected as D input.

However, there is a small workaround that works for me is that when I connect that dongle into my PC when it is turned off and then I turn it on while the dongle is already connected. The controller shows a blue light and everything works normally. It is not detected as a D input device, it is detected as an X input device and everywhere, including steam, it is detected as an Xbox 360 controller.

This workaround, I did not know before but it is available or written on arch wiki. Here is the link. There is another way to always connect that device as an xinput device rather than relying on turning the PC on or off. It requires sudo permissions but I never got it to work properly, I always have to rely on rebooting the PC.
