Although it doesn't specifically mention it, this kernel supports Apple's Magic Trackpad 2, which is a real blessing. Original source: https://github.com/robotrovsky/Linux-Magic-Trackpad-2-Driver I've been using this since last night, and with some tweaking, it works really well.

Awesome, I thought only 4.20 will have it. Have you tested it with Bluetooth?

I'm on 4.18.16-041816 Generic and just paired it with bluetooth, which is surprising to me. I typically keep it wired since Windows doesn't always play nice with the MT2.

That's really nice. I remember having to use Read-Only on a few Raspberry Pi projects because they have a tendency to corrupt SD cards. Getting a free storage performance boost would really improve usability for my past use cases.

I recommend only writing when it is necessary, so e.g. you might want to log to /dev/null or tmpfs (I chose the latter but it adds up in RAM). Also, disable swap if at all feasible. On top of that I recommend industrial grade SD cards using (a)MLC. They might be a bit more expensive but it is worth the stability. I learned this from these posts (among others in the same thread 'Raspberry Pi microSD card performance c…

Thanks for the links, they were good reads.

Coincidentally, for those projects I did end up mounting to a tmpfs, syncing configs from a server, and writing them to a SPI flash chip with FEC. Fun to know that others suggest the same!

I was just thinking along the lines of performance improvement for the absolute garbage SD card speeds. I just remember how flipping long it would take to load a program off those things.

Okay I'm on 4.18.14 and just tried plugging my MT2. It _basically_ works, but the trackpad feel is as bad that of my Thinkpad's. And none of the gestures, including two finger tap, works.

EDIT: looking at dmesg, it is registered as `hid-generic`. So not using the new driver?

Dig through https://github.com/robotrovsky/Linux-Magic-Trackpad-2-Driver and make sure you install `mtrack`

I found that I had to modify the 50-mtrack.conf and also the 90-magictrackpad.conf to get the two-finger tap for context menus. There's probably a better overall configuration, but I'm still fresh to this specific thing.

When I get back to that system I can post some more detailed information.

But this is a false dichotomy. They could just refuse your code without calling you an idiot.

Of course there exist examples of Linus calling or even implying that individual people / organisations are "idiots" and they are wrong (and he has acknowledged this). But in the vast majority of cases the criticism is aimed at the code itself and I genuinely don't see the issue with this.

Neither do I

Linus may have been sincere in his writing, people saw him as this verbally abusive boogeyman who would tear people apart, which led him to become that type of person more and more. The embrace and extend going on over in Redmond right now is threatening though, what better time to use your clout and power over a competitors org (that your a member of now) than when you have forked what depended on their software, ex…

Can you provide more context re: "The recent reaction from Valve is telling, I think Gabe is fearful about the current state of affairs" ?

Microsoft could lock out 3rd party app stores like Steam, and already has on certain versions of Windows.

Valve is trying to protect themselves from irrelevancy, they have all their eggs in the Windows basket, while consoles and mobile are owned by companies that are massive comparatively.

The first version which boots on RISC-V hardware (and QEMU) out of the box. Previous versions needed out of tree patches[1] for essential IRQ and device driver support. Excellent work by many people getting these upstream. [1] https://github.com/riscv/riscv-linux

I'm afraid to say there's a small correction after I went to the RISC-V BoF tonight[1]. This kernel only boots on QEMU (which I had tested), but still requires a small number of driver patches to boot on the HiFive Unleashed board - I did not get around to testing this because our boards are all consumed building Fedora and it's not very convenient to reboot them. They are expecting these extra drivers will be upstream in 4.20.

Some important fixes in amdgpu for Vega there. It's finally waking up from sleep properly when using DisplayPort.

This was my biggest issue with 4.17 & 4.18. I just recently upgraded my system to a Ryzen 2400 and I have had quite a few issues. Keeping up with the latest kernel builds with ukuu has helped but it would be nice to have a stable kernel that works with my CPU/GPU. Hopefully, 4.19 will make it to stable tonight and I can upgrade tomorrow. :)

I have Vega 56 and was bugged by it in 4.17/4.18 cycle. Finally 4.19-rc fixed it. But there are a few DisplayPort 1.2 related annoyances that still remain.

> Reusing the previous example, the purpose of the GPL was to drive out proprietary software; yet the people using it in Linux do not yield it that way. That was an outcome that was hoped for, not a purpose. The purpose is pretty explicit in the preamble paragraphs [0] - to promote a certain style of freedom. As a body, the Free Software community wouldn't deny that if creating non-free software is legal, then free s…

You can be autistic, not good in social situations, and still not abuse, harass, or discriminate against people. Associating abuse and harassment with being a fundamental part of autism is not ok. Autistic people can fully understand "do not perform this behaviour again" - they can also understand consequences of their behaviour, including both positive ("people like to talk to me more and are more accepting of my id…

I suppose you are arguing that meritocratic communities aren't the best setup for a community - which is a pretty reasonable one. I mean, the big successful countries aren't meritocracies, they are democracies. So fair enough.

> Finally - if you allow abusive people to exist within a community, you by definition exclude everybody who they would abuse.

You are going directly to how a meritocratic society might fail. Meritocratic communities can fail, but so can communities with any ideological underpinning.

Sometimes you have a choice between someone who knows exactly what they are doing but has questionable behaviors vs. someone who doesn't know quite as much but is better behaved. A meritocracy gives power to the first person. We can have long conversations about whether that person should strive to improve themselves over time (pretty easy to answer that question), but change is slow and in the interim a choice has to be made.

With haptic feedback support? That's amazing, I just bought one of these (as it is the best trackpad available by a long shot). Even Windows doesn't support this. I did find this one [1], but it doesn't seem to be signed so a shady source. [1] http://extramagic.forbootcamp.org/

Not sure about haptic feedback yet. For Windows, try https://github.com/imbushuo/mac-precision-touchpad/releases I went through a lot of sketchy drivers like that one you mentioned, but this one worked the best without any helper apps to mess around with. Its a shame its taken so long for other OSs to support such a great device.

Thanks for the link. I did search quite a bit, but I did not find that one.

I noticed a few things from the link: the Apple Magic Trackpad 2 support is "not stable", and it does not appear to be usable via Bluetooth.
