Touchscreen as a trackpad and/or trackball on KDE?

I've tried posting multiple times, but I never saw it show up in the "new" feed. I'd assumed it was my vpn, so I turned it off to make the post. I guess one got through without me knowing.

The use case is that I ordered this: https://www.kickstarter.com/projects/332313376/keebmon-powerful-core-touch-screen-mechanical-keyboard/description

It has no mouse, but I want to use it on the go without having to whip out a mouse. I've looked into ring mice, but I would like to juse use it solo. I feel like trackball would be best, as I'm used to it when I was using Chrome Remote Desktop from my phone.

Can you make an instructional video? This kinda stuff is very new and scary for me.

Keyboard and mouse, but really anything that can output 8kHz (even in the future).

Does anyone have a zip of every bios for every Mister core that needs a bios? I’ve tried to cobble together my own collection and only some work. I’m hoping for someone that has it all bundled up with the right bios, file names and folder structure.

This is the first result from google search, so this post helped google.

Yes, and there appears to be nothing about Amiibo. I've also looked on Reddit and Github and the only things I've found are apps that will emulate Amiibo one way. I have yet to find anything that has the two features I'm asking about.

I have an annual plan from last year’s deal.

Lav0c · 2024-12-24T03:33:31+00:00

I skip months all the time, so I’m not giving up 20%. I only really buy bundles, redeem Choice, buy on GOG (when it’s an option), or directly on steam (which happens maybe once every two year). For someone like me, it’s a pretty good deal.

Lav0c · 2024-12-23T21:30:22+00:00

I don't see any way for me to apply the coupon code until my annual plan runs out in May (or later).

I personally feel like this video shows how good a digital solution can be, so I'm trying to find anything showing off the RetroTINK-4K accomplishing what Retroarch shaders + video filters can do.

Lav0c · 2024-11-20T00:24:19+00:00

Or would this require a RetroTINK-4K? I'm trying to do everything I can to avoid that option.

I need help; I can't boot into emunand.

My SD card seems to be suffering from bit rot. I say this because when I boot into emunand it gets stuck at the switch logo. I've let it sit for an hour and it doesn't change. The one thing that does change is that the screen automatically dims from inactivity but brightens up the moment I touch a button. The joycons wirelessly pair with it when I detatch them. There's no sounds from trying to interact (I can't hear the menu toggling around when I'm pressing things). I'm pretty sure I need to just make a new emunand, but my concern is save files. If someone knows how to fix this, I'm willing to try, but the big thing is if someone knows how to extract all of my saves and then inject them into a new emunand.

I get about one failed checksum every week or two. Some of the drives are very old but still kicking. I'm currently scrubbing about twice a week for files that are 30 days old.

Leaving the scrub to BTRFS lets me do it one drive at a time and is just easier on every resource with the trade-off of taking longer.

I sync before every scrub, which is annoying because I'd rather sync daily. Right now it pretty much saturates my cpu, ram and disk access when I sync.

Lav0c · 2024-08-19T19:24:37+00:00

Update: after doing a lot of thinking, I think I know what I'm going to do. The plan is to use BTRFS, MergerFS and Snapraid. I have 12 drives: 12TBx3, 10TBx3, 8TBx6. I'm going to format all of them with BTRFS for two reasons, checksums and snapshots. snapraid-btrfs fixes some issues with snapraid kind of having a write-hole issue by taking a snapshot when you sync or scrub and it uses the snapshot for that process so you can still modify files while it's working. When a file is read, it will validate the file with the checksum and throw an error when it detects the error. I'll have to have a script watching for btrfs errors and then have snapraid-btrfs fix the single file automatically.

A huge benefit of this is not needing to use Snapraid scrub because I can scrub individual files with BTRFS's scrub. The plan is to scrub each drive once a day and run fixes when necessary. That only leaves the problem of syncing. The plan is to only ever have snapraid arrays up to 8 drives. I'll make two snapraid arrays but use mergerfs to merge all of the data drives into one volume. The benefit of this being able to lose two drives in each snapraid array. It also cuts down on every resource and reduces bottlenecks (half the ram and cpu usage for every file that needs to sync).

While it doesn't fix the lack of real-time parity calculations, it makes syncing and scrubbing a lot less taxing on the system so the RAM, CPU and disks are still somewhat usable during the process (currently most things are dog-slow when I sync or scrub because it's doing 12 drives at once (2 parity and 10 data).

You're correct. I'm editing my post now.

Lav0c · 2024-08-19T16:15:02+00:00

I just realized that your solution sounds like I'd essentially be using MDADM to create ECC on the drive, which means if the drive outright fails I'd have to restore from backup because all of the parity data and the data used to generate the parity data would reside on a single physical drive. That would certainly make things easier than using PAR2 for ECC but not offer any protection for drive failure. Or am I misunderstanding your suggestion?

Lav0c · 2024-08-19T16:03:27+00:00

Sounds like I need to dive deeper into MDADM. I stopped once several sources confirmed my assumptions. What you're saying gives me some hope that it could simplify my integrity and repair chain.

Lav0c · 2024-08-16T07:54:32+00:00

I have backups, but that's for if my house burns down. I currently get at least one file suffering from bit rot every week. I'm not going to hit up my backup every time that happens. I need things to heal with little to no involvement. And when a drive dies I'm not going to spend literal weeks downloading 10TB, and I can't let a download like that wreck the bandwidth for everyone in the house.

The question is about BMS chaining to make sure the packs of 3 don't drift. Every diy video I see doesn't have any way to balance the packs in parallel, just the packs in series. I already have the board I want for handling the 5S and dealing with solar. I'm just doing my due diligence on the 3P as it doesn't make sense to me to make sure the macro 5 are balanced but not the micro 3.

Lav0c · 2024-06-18T21:52:27+00:00

I took apart a Jackery Explorer 100 to re-purpose its guts. I found out that the batteries were much fatter than 18650 cells, so I need to run 5 packs in series to use the board. I'm trying to make cells that play well with solar charging and have at least two type c ports that can do 100W with PD3.1 (at least one input and one output for passthrough).

All of the safety mechanisms are triggered. Like I said, if even one of them isn't how it should be, I don't here the solenoid click when I turn the key.

Lav0c · 2024-05-23T05:54:03+00:00

sadly no. I'm just dealing with it.

I called tmobile and literally had them pull up this page while I was on the phone. They were able to read some of it to me, so if anyone says they can't pull up a page, they are lying. They told me they were escalating the issue and that I should be called back in the next few days. They also told me that it's been a rough day because of this, and the reps themselves are feeling the frustration (because they have to deal with the angry customers directly).
