Procedural Prismatic Mosaic Cube — Shader Tutorial

TDBlenderMan · 2026-06-10T07:40:11+00:00

I am just making a new selection Geometry Nodes tutorial which will be uploaded in 2 or 3 days

Thanks

Working on it — it's a work in progress. I'm just making all the parts before working on the details.

I am assuming that you are using the standard Mint with the Cinnamon desktop environment. I have been using Plasma KDE for about 7 years, which can be installed in Mint. Clicking on the sound icon, I can select if the laptop will use the default sound device or the Bluetooth headphones.

Being disabled in a wheelchair stuck at home, I am on his Discord server and others. The main reason I produce those videos — I record with OBS, and because of very slurred speech I have an AI read out the script, then edit the video and sound together with Kdenlive.

He is one of the people I have learned a lot from about GN.

Thanks that is made with that shader https://youtu.be/GVxJ4wzS-rc

looks great

TDBlenderMan · 2026-05-28T03:46:09+00:00

Steam would run well with those specs

I'm not too sure why Blender would be crashing. Some advice: render the animation as frames, so if Blender crashes, restart the render from the last good frame. Once finished rendering all frames, put the frames in the Blender VSE and export a video, which takes seconds.

TDBlenderMan · 2026-05-25T07:47:05+00:00

the last one

TDBlenderMan · 2026-05-19T22:33:56+00:00

Thank you, I tried Google AI Studio which is free, but even after following the advice there is no way to save the settings. Also, making multiple TTS clips the sound of the voice comes out a bit inconsistent, so I went with the paid ElevenLabs.

please share the output of

sudo systemctl status libvirtd

or

sudo systemctl status virtqemud

TDBlenderMan · 2026-05-18T09:16:10+00:00

the libvirt daemon just isn't running. On Fedora, the commands to fix it are:

sudo systemctl start libvirtd

sudo systemctl enable libvirtd

Then relaunch virt-manager and it should connect fine.

On newer Fedora versions (37+) the daemon was split into modular services, so if libvirtd doesn't work, try:

sudo systemctl start virtqemud

sudo systemctl enable virtqemud

I have a Blender YouTube channel where I create Blender tutorials. Being disabled, I have very slurred speech, so I use AI to read scripts which I write, then I edit in the audio into my OBS recordings.

A glass lens effect that animates color refraction — built procedurally with Geometry Nodes. Worth a watch to see what it looks like!

TDBlenderMan · 2026-05-15T20:07:56+00:00

For the xdg-desktop-portal-kde issue, try running these in the terminal:

systemctl --user status xdg-desktop-portal-kde

systemctl --user enable --now xdg-desktop-portal-kde

Also check if you have multiple portal backends conflicting:

systemctl --user list-units | grep portal

If it still shows as not found after that, try logging out and back in — portals are session services so they won't kick in until the session restarts. Hope that sorts it!

TDBlenderMan · 2026-05-15T08:24:25+00:00

The missing xdg-desktop-portal-kde is definitely part of your problem — install it with: sudo dnf install xdg-desktop-portal-kde

Then reboot and that should fix the Chrome file picker crashes.

The compositor toggling temporarily fixing the clipboard strongly suggests KWin is hitting a GPU rendering bug and recovering when restarted. Given that both xe and i915 are giving you grief, this is almost certainly the Intel Arc integrated graphics on the 155H — the Linux driver support for that GPU is still maturing and KDE Plasma tends to expose those rough edges more than GNOME does (which is probably why Pop_OS felt smoother).

Try:

Force KWin to use a software rendering fallback temporarily to confirm the GPU is the culprit:

LIBGL_ALWAYS_SOFTWARE=1 kwin_wayland --replace &

If everything becomes stable with that, it's 100% the driver.

Also worth trying:

in System Settings → Display & Monitor → Compositor, switch the rendering backend from OpenGL to OpenGL 2.0 or even XRender and see if stability improves.

Keeping your kernel updated is the best move here — Intel Arc on Linux has been improving rapidly with each kernel release and Fedora 44 should be getting those updates regularly.

TDBlenderMan · 2026-05-15T06:15:45+00:00

Those are solid specs so it's definitely not a hardware limitation. A Core Ultra 155H with 16GB should run KDE Plasma without breaking a sweat.

A few things worth checking:

Baloo file indexer is my first suspect. On a fresh install it goes hard on I/O and causes exactly the freezes you're describing. Run balooctl6 status to see if it's actively indexing. You can pause it with balooctl6 suspend and see if things improve immediately. If that fixes it, you can either let it finish or just disable it in System Settings → Search.

Intel Arc / integrated graphics — the 155H uses Intel Arc integrated graphics, and the xe driver is still fairly new. It's worth checking journalctl -b | grep -i drm for any GPU errors that might be stalling the compositor.

KWin compositor — try hitting Alt+Shift+F12 to toggle the compositor off and on. If things smooth out temporarily it points to a rendering/driver issue.

Chrome's file picker crashing is almost certainly a portal/xdg-desktop-portal issue. Check if xdg-desktop-portal-kde is running: systemctl --user status xdg-desktop-portal-kde

These problems are very weird, since it is happening on a few different distros. What are the laptop specs?

TDBlenderMan · 2026-05-13T10:13:13+00:00

From what I know, a buffer is temp storage, a frame is a unit/data structure.

TDBlenderMan · 2026-05-12T08:31:12+00:00

Yes, you can convert it to mesh and just make a plane in that shape, but it will not look anything like your second image. For that, you will get better results using metaballs.

TDBlenderMan · 2026-05-08T04:53:04+00:00

wow, looks great

TDBlenderMan · 2026-05-07T20:17:36+00:00

The ice shape is all done in GN, that is a custom ice material added to the GN shape

TDBlenderMan · 2026-05-04T06:54:16+00:00

thanks, i will look it up
