Possible to sandbox GUI apps using Gvisor?

Gvisor is a kernel compatability layer for linux containers. I am trying to find a solution to sandbox everyday apps I use including browsers, code editors and other programs I work with. I have been trying to get Firefox working using Gvisor and Podman along with nested xorg servers but haven't been successful yet.

Have you guys tried anything similar? I know I can use VMs and bubblewrap but a well isolated container with no access to the actual kernel looks like a more promising idea to me.

NVIDIA Video Acceleration on Linux - What's the deal?!

Quick question and a rant all in one, because this is absurd.

Why in 2025 does playing a YouTube video on Linux with an NVIDIA card make my CPU scream like a banshee? On Windows, the same video and the CPU is barely breaking a sweat. After a fresh install of any distro, the problem is the same—the browser chews through the video on the CPU.

From what I understand, the problem is simple:

Browsers (Chrome/Firefox) want to talk through the open VA-API standard.

NVIDIA stubbornly only speaks its own NVDEC language.

The result? A failure to communicate and a fallback to the CPU.

Of course, the community has figured it out. The solution is the "translator" nvidia-vaapi-driver. But even with it, you have to do some tinkering:

Install the nvidia-vaapi-driver.

In Firefox, you mess around in about:config.

In Chrome, you add startup flags.

Finally, you fire up nvtop and pray that you see the load on the "DEC" engine, not the CPU.

The funniest part is that players like MPV or VLC handle this without a problem—you just have to point them to nvdec. This is mainly a browser issue.

My question to you all: Is this still the best way to handle this? Are there any new, magic tricks I don't know about? Or are NVIDIA or the browser developers finally planning to fix this at the source? Let me know how you're living with this.

Zorin OS WAY easier than Mint for Newbie

I keep seeing people recommending Mint for new Linux users. I got sick of Apple and Microsoft. I decided to switch to Linux and installed both Zorin and Mint. In my opinion coming over as a complete noob Zorin is WAY easier to use than Mint. Mint is probably better for someone with more than average computer literacy. The fact that you have to learn the terminal is crazy. Zorin is beautiful, intuitive, and holds your hand every step of the way. I don't know about flat packs or this and that, what I do know is that when I needed to download an image writer, Zorin recommended I download a Linux equivalent and it worked perfectly.

I am using mint now and feel like a computer programmer. Installing software through the terminal is confusing and not working. I don't care that it might be easy to experienced computer users. It isn't easy for me and I know enough about computers that I was able to install 2 Linux distros on my Windows Dell laptop.

My Linux Journey

Just completed documenting my entire transition from Windows 11 to Arch + Hyprland. After 15+ years on Windows and over a year of daily driving Arch, I've compiled everything I learned into a reference guide.

This isn't a beginner tutorial, I assume you know the basics. It's more of a "here's what actually works in practice" reference guide.

Hope it helps someone speed up their Arch setup process. Open to feedback and contributions!

That's the first topic they share, so no need in timestamps.


If someone has a subnoscription to floatplane (their own subscriber-exlusive platform), you will have a form to post a question and redirect it to Linus Torvalds and they gonna ask him.

Mint or Bazzite

I'm sick of Windows,

I was originally just going to wait for SteamOS but I want to "move out" now. Windows Explorer keeps crashing, causing my computer to blue screen. I try searching things up through windows key and it looks it up on the website. I am not interested in Windows 11 and its ads.

My specs are

CPU : Ryzen 7 5800x

GPU : RTX 3080

Ram : 32 GB Ram

I got C: drive and D: drive and I probably plan on putting one of them in my D: drive, keeping windows in C:, I plan on playing games and doing youtube.

But I also do some productivity like video editing and drawing (I use Sony Vegas, and Clip Studio Paint). Hopefully there's a way to make them work, especially drivers for my drawing tablet. Would definitely like to hear more advice on this. If not then that's why I'm keeping the dual boot.

And also will my files be able to be transferred over still so I can see them?

I have a ton of questions but I don't want to just ask 500 questions in a singular post.

OS drive filling up

I am building a small media NAS and have installed OMV (a Debian fork) on it.

The OS is installed on a 128Gb SSD and there are 2 20Tb 3,5" HDD's that have been software raided into a single volume mounted on a /Media folder.

Now when I start putting files into said folder it stops at ca. 111Gb and tells me the OS drive is full.

how? why?

(I hope I got the flair right, if not, please don't shoot me ;-) )

Would you use a free, lightweight thin client OS for old PCs or Raspberry Pis?

Hey everyone, I’m experimenting with a tiny, fast Linux OS designed for thin clients—basically a lightweight system that boots quickly, supports remote desktop (RDP/VNC), and includes an easy setup wizard.

It’s meant for:
Old PCs and Raspberry Pis
Home labs or classrooms
Anyone who wants a fast, simple thin client without commercial licenses

Before I go further, I want to know: would this be useful to you?
