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.

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.

Can I get a better Nvidia+Wayland experience by using prime and connecting the display to an AMD iGPU? I saw that in the last year Nvidia Prime had some improvements, do they make it feasible?

I can't just try it because I have yet to buy said AMD iGPU. And I'd like to know it before buying

I don't like my ssh keys being stored in plain sight, I also don't like having to type a passphrase to use them.

On windows, once you run ssh-add, the key is stored in a secure way and managed by some kind of session manager (source), at that point you can delete the key file and go about your life knowing that the key is safe and you won't need to type a password again.

I would like something similar on linux, like storing the key via libsecret as you do with git, so that you can access your servers without having a key in plain text.

I think it's possible to generate a key with a passphrase and have gnome-keyring or kwallet remember the passphrase, but it would be nicer to just securely store the key itself.

Can that be done?

I have a projector that needs limited rgb range, but for some reason (maybe a faulty hdmi-vga dongle) the intel driver selects full range. I want to force the limited rgb range when I plug the projector, but I need it set to auto normally, because my usual monitor needs full range.

I read this guide that explains how to use proptest to switch mode when in wayland. The problem is that running the command when the gnome session is open doesn't work and returns an error 243 (I can't find it in errno.h, but google says its EACCESS). The guide deals with this by launching the command with systemd before gdm starts, but as I said, I only want to force the limited range when using the projector.

I noticed that I can switch to a tty, set the range, and switch back to gnome while everything is still running and it works, which is my current "workaround", and I'd like to automate it. So I thought that there's a moment when gnome "takes control" of a screen where this can be set. I tried to use a udev rule to switch as soon as a monitor is plugged, but it exits with 243 as usual. I suspect gdm has a way to automate such things that might possibly work, but I can't find it, I only read about some xorg scripts.

Also, there's this issue that's being worked on. One of the commenters uses an udev rule as a work arount but it doesn't work for me.

When the jack is inserted the internal speakers stop making sound and the only analog out is the jack, as it's common on laptops. But I want to address the two analog output individually so that I can:

• Still select the speakers when headphones are plugged
• Have different sounds come from headphones and speaker
• Mix them with carla or other audio software

My alsa/pipewire settings are all default, I'm on a thinkpad t480s with fedora 38. My sound card is an intel hd audio card, with a realtek ALC257 analog chip.

I tried disabling auto_mute and rising the volume from alsamixer but nothing happens. Then I switching pipewire to "pro audio" but it doesn't separate the analog outputs. I also tried setting the indep_hp hint from hdarackretask but it doesn't change anything.

The hint enables a new "independent hp" option in alsamixer, but it can only be enabled by the cli and it doesn't work either.

I can provide configuration files or other info if needed but since they are all pretty long I didn't include them in the post. Also because I didn't edit them so they are just fedora's default.

Thanks
