The hardware still needs to be brought up and initialised. But the software is the real problem here. The kernel gets fully up in seconds, but then you have to initialize the rest of the OS

The pc ecosystem is modular by design. The kernel will figure out itself the available hardware, moreover there are only two major CPU manufacturers (in the pc space of course), which means you have only two platforms to support.

Mobile phones instead are not modular, they use SoC. While most common socs are from Qualcomm and mediatek, there are a lot more smaller manufacturers. Plus, even if most often they use the same reference design for compute cores, the rest of the soc is often custom and wildly different from others. All of this to say that the kernel needs to already know exactly how the specific soc of the device works, instead of figuring it out on the fly. Which is why you need to check compatibility.

The brick thing instead is because the bootloaders in these devices are usually very locked down, so sometimes you need to replace the bootloader with a more open one, with all the risks that this entails

They die. Full stop.

Not even Microsoft had the strength to maintain a browser engine, that's why they moved Edge to Chromium, they gave up.

I'm using sunshine for remote gaming on my Linux PC. Because I use Wayland and don't have an Nvidia I use kmsgrab for capture (under the hood sunshine uses ffmpeg).

I have noticed that I can enter tty and kmsgrab will capture it as well. If it just captured after logging in my user I wouldn't be surprised, but it also captures the login screen.

I autostart it at login using my systemd user configuration (not systemwide) so it should just have my user's permission level. I get the same results if I put it in KDE's autostart section, so it's not a systemd thing.

Why does that work? Shouldn't you need special privileges to capture everything?

The installation instructions tells you to do sudo setcap -r $(readlink -f $(which sunshine)) is this the reason why it works? What does the command do exactly?

SOTTR can now run in proton-experimental (it used to crash due to a missing vulkan feature), but how does it compare to the native version?

Normally I would just use the native version, but got the game from epic, which doesn't provide the native build. So if I wanted to run native I would have to acquire the game from other sources (keep in mind that I own the game on epic), which is less than ideal. But I wouldn't do it if there's no advantage.

The USB protocol was simple by design, so it could be implemented in small dumb devices like pen drives. More specifically, it used two couples of cables, one couple was for power and the other for data (four wires in total). Having a single half-duplex data line means you need some way of arbitrating who can send data at any time. The easiest way to do it is having a single machine that decides who gets to send data (master), and the easiest way to decide the master is to not do it and have the computer always do the master. This means you couldn't connect two computers together because they would both try to be the master.

I used the past tense because you may have noticed that micro USB have 5 pins and not 4, that's because phones are computers and they use the 5th pin to decide how to behave. If it's grounded they act as a slave (the male micro to male A cable grounds it). If it has a resistor (the otg cable has it) it act as master. And if the devices are connected with a wire on that pin (on some special micro to micro) they negotiate the connection.

When they made usb 3.0 and they realized that not having the 5th wire on the usb-A was stupid, so they put it (along side some extra data lines) that's why they have an odd number of wires. So with usb 3 you can connect computers together, but you need a special cable that uses the negotiation wire. Also I don't know what software you need for it to work.

Usb-c is basically two USB 3.0 in the same cable, so you can probably connect computers with that. But often the port on the devices only uses one, so it might not be faster. Originally they put the pins for two connections so you could flip the connector, but later they realized they could use them to get double speed.

Do you have an AMD aura GPU? Do you also use Linux? There's this this driver that needs to be tested.

It allows you to control the lighting of the GPU using programs like openRGB.

I wrote that PR that should make it work for more GPUs, but I only have an RX 480 so I can only test that one. It would be useful to try it on a Vega gpu.

If you have an rDNA 1/2/3 GPU, it most likely won't work, but without the card there's nothing I can do.

On a side note, if you are interested in maintaining the driver it would be great.

Detailed issue

Basically Kwin and other programs (simple xdg-desktop-portal or even gimp) crash and they bork the entire screen with no recovery other than rebooting. When the program that crash is Kwin it's particularly bad because it happens at login.

This is a short appreciation/user experience story. Tl;Dr I'm enjoying my time on linux

I have been using Linux for a while (gnome for a year with an Intel UHD gpu, and KDE for a couple of months on a recent AMD gpu), and till now there was no brightness slider. Moreover, I have used the same display with windows for several years and there was no slider as well.

As far as I know (I looked up online some years ago, but this info is sometimes hard to find) my display supports DDC/CI but doesn't expose brightness (haven't actually tried).

For some reason, about a week ago a brightness slider appeared on KDE but it didn't do anything. Yesterday while updating some unrelated stuff I noticed the slider again and moved it for shit and giggles, and the brightness actually changed...

I have several questions... and I don't even know which piece of software is responsible for this... but thanks

I have been using Linux on and off for several years, often alongside windows, but I have entirely switched to it (almost, I still have a windows PC that I use once in a while) about 16 months ago. I have to say that Linux does take a lot more effort in getting some things to work, but when everything goes smoothly it's sooo good, and improves every month.

In the span of a year my desktop experience has only got better. But the shock was when I booted up an Ubuntu 16.04 cd I had lying around to fix grub on a dual boot machine and it was barely usable. Now instead it's almost "plug and play". Plus Nvidia cards are getting more and more usable with every update, explicit sync is almost merged, and prime works fine already.

There won't be a year of the Linux desktop anytime soon (there's still too much that needs improvement), but the next years will definitely be exciting.

P.s.: does any of you know why display brightness works now?

I have a Nvidia gpu with the latest proprietary drivers, and I'm trying to play BAA from egs (using heroic) but physX doesn't work.

I have run the automatic winetricks (I don't know which ones because heroic doesn't tell) and I have tryed this also the environment variable PROTON_ENABLE_NVAPI=1, but it still doesn't run on the gpu, even if the message "no hardware physx detected" stopped showing.

And if hardware acceleration doesn't work, I get the same behaviour on arkham city, but the game runs at double the framerate, even if using the cpu. Would it be possible to get asylum to run like city? I have tried swapping some dlls but nothing.
