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.

Take note of the quote in the article...

OP/bug finder here with some clarifying information. It's a common misconception that this issue can only be abused if you use HTTP boot. That is not the case at all, otherwise it wouldn't be Critical. This bug can be abused locally (privileged malware can overwrite the EFI partition), from an adjacent network if PXE boot is enabled (w/ MiTM), or remotely if HTTP boot is used (w/ MiTM).

More details on these scenarios:

1. A remote attacker with no privileges in a man-in-the-middle (MitM) position could leverage the issue against a victim machine that uses HTTP boot. No direct access to the victim machine is required.

2. A remote attacker with privileges and code execution on the victim machine could leverage the issue to bypass Secure Boot, even if the victim does not already use HTTP boot (as long as firmware has HTTP support). How? Several ways:

• An attacker can edit the boot order variable to specify a controlled attacker server.

• An attacker can chain shim->GRUB2->shim (via HTTP). For this technique, an attacker would overwrite the boot loader in the EFI partition to a legitimate shim and GRUB2 image. The attacker would create a grub.cfg that chainloads a new shim via HTTP. This is possible because GRUB2's device syntax allows you to specify any supported device, including HTTP (if available).

3. An adjacent attacker with no privileges in a man-in-the-middle (MitM) position could leverage the issue against a victim machine that uses PXE boot. PXE is separate from HTTP boot, but similar to the local vector, an attacker can chain together shim (via PXE)->GRUB2 (via PXE)->shim (via HTTP).

Plasma 6 Release Candidate 1 has landed.

We are less than 50 days away from the final version of #Plasma6.

Along with Frameworks 6 and KDE Gear 24.02, the Megarelaease on the 28th of February will be one of the biggest and more complex upgrades in KDE's history.

One more RC will be released on the 31st of January and then it will be (hopefully) clear sailing until the final release.

Hello everyone,

I just joined the Linux community on Lemmy.

Love Gnu/ Linux. Would love to create my own custom Linux servers and machines one day, and I'm already on that path.

(Maybe only a quarter of the way though. 😁)

I don't know what else to say, other than that the goals and admirations and aspirations of Gnu/ Linux fall in line with my personal endeavours in creating a collaborative and supportive environment that drives creativity, freedom, and independence.

This initiative comes from the beautiful but encouraging and supportive community that I had the chance to speak to and talk to (in matrix), which focused on the social values of providing free and opensource resources to people around the world - which is unfortunately neglected by many, if not exploited and abused, and not mentioned, around the world (or at least the society that I have been in contact with in my life, including in the academic aspect and the organisational aspect).

Of course, I also listened to Linus and Richard stallman respectively (I do not endorse any of RMS's political, religious, or ideological beliefs).

The building blocks upon which helped create Gnu/ Linux what it is today. The ankle point that holds many organisations and companies around the world. The hard working and faithful people that strived in creating values in all of their forms to support such initiatives.

And it reminds me of a beautiful qoute, said by [childhood] friend, Mr. Fred Rogers:

"L'essentiel est invisible pour les yeux".

"What is essential is invisible to the eyes".

Originally written by good sir story writer: Antoine de Saint-Exupéry. (Recommend reading chapter 10).

My nickname here (or username) does not reflect my real name, but I do find joy in nicknames too. You could call me Engelbert, for casually-endorsing-social-conversations' - sake'.

And I am here to learn, and exchange knowledge and experiences with others too ! Help and give advice, and seek out challenging issues the community may be facing.

Talk to me about anything. Religion, culture, history, politics, some good philosophy, but mostly Gnu/ Linux, Rust, design philosophy !

(If you feel that the subject is too sensitive, we may have a private council together 😀).

My goal is, as a gesture of goodwill and thanksgiving, to give back to society and give back to people who helped shape and create this society the way it is today, all things regarding Gnu/ Linux and the opensource objectives.

I have read more than 5 books in rust, and I'm still nowhere near perfect. I had more than 50+ projects in rust (small to medium, nothing crazy), had experience in C, C++, and C#.

On final note, I would like to mention these beautiful words by imam Ali: "Hide the good you do, and make known the good done to you !".

Thank you for having me !

Sir Engelbert.

Like choose your-own-ending novels and BASH? What would you do if you suddenly had ssh access to someone else's server? This is a really fun corner of the net. Excellent resource/trainer/time-waster. When I talk to people from the DIY linux/selfhosting/FOSS communities, many folks haven't heard of it.

What other cool stuff do you know about? Think it sucks and want to tell me why?

Note: I am not at all associated with this project - just think it's a valuable stop on the good 'ole internet.

At the moment there is slim pickings for other communities to join if this instance is chosen by a user to be their home server.

Presumably other instances have to approve linux.community federating with them before their subs can show up? Is it that this instance is new, or is there some other reason. u/nkukard can you chime in?

EDIT: A-ha! I was searching poorly! Once a member of a instance subscribes, it pulls it into that instance for easier discovery. Neat!
