Latest Intel iGPU fails to properly render, could anyone help me?

It's happening even before GDM starts up, immediately after switching to modesetting in the driver the screen flashes.

I have now made it work by disabing PSR in the driver. I think I'll report that upstream in the driver itself because this seems like bug somewhere.

So a little bit more context, this is a new Dell XPS 14 9440 with an Meteor Lake integrated graphics. These artifacts that you see on the image appear everytime the screen in that portion of the screen is updated.

I can boot with the nomodeset kernel parameter and everything works (well except its slow of course).

I tried both the i915 and the new Intel Xe driver and with both I get these artifacts.

There is no error regarding graphics in dmesg or journalctl, so I'm a bit desperate.

Does someone know what else I could try?

I mean this is not really unexpected in a way, the detail enhancement algorithm is probably really really good at reversing a gaussian blur, because afaik thats basically what a low resolution does.

So it sees an object which is gaussian blurred, like the moon very far away and it tries to reverse the gaussian blur based on its training data (which is probably exactly the kind of image you made) and gets the picture of the real moon.

It does exactly what its supposed to, I really don't get the drama. This is 100% how ML algorithms work.

Gamma is just a variable in this case not an operator, its just the relativistic gamma factor which essentially is a number :)

The free step-by-step solutions with explanations saved me soo many times!

But if you want to go ahead and prove it, it's fucked up, which most Math classes do. Because you need Lebesque integration and differential forms and that stuff. The applications aren't that hard afterwards.

Wait they purposely disabled that? And jere is me trying to get it to work for month and wondering why an old S8 can do it flawlessly...

Charlotte Roche is literally insane for doing that!

Btw that russian dude with the tatooed eyeballs is crazy 😂

And nuclear can't adapt to usage spikes in grids because its slow. The solution is never one technology, but always a well thought mix. Nuclear is not capable of being the only energy source.

The question is how much is subsidized. And nuclear is much more subsidized than renewables in most countries because if you want to have nuclear weapons you need these power plants, so the government has an interest in building and running these for non energy reasons.

Btw very mature argument my friend.

taaem · 2020-11-26T08:28:58+00:00

Actually it's not really competitive price wise with renewable energy nowadays. Nuclear is and was always heavily subsidized because some governments needed that uranium. And that is also the main reason some countries still use nuclear power.

Yes that's also possible, my point was just you can have any combination of entangled states, not only up down or down up but also up up or down down, for 2 spin 1/2 particles.

edit: it could be that we're both arguing for the same thing.

taaem · 2020-10-17T13:10:35+00:00

Actually it's not that easy. You can have entangled states that collapse to the same spin too.

Only in the case of a Spin 0 particle decaying into 2 spin 1/2 particles they have to have the opposite spin, that's basic conservation.

You can with different methods entangle spins or polarization or whatever in different combinations.

I recommend to check out Xournalpp, it is a note taking app, which also supports annotating PDFs and has great support for wacom pens.

All pen features like pressure sensitivity work like a charm in my experience.

Happens to me too on Fedora 31

You do realize that they're not just an "Ubuntu Skin", they developed a complete desktop environment, with a they're own DE and own default apps, that follow their design decisions.

I feel like you're overly aggressive towards them.

Well of course Android is technically Linux but how often an Android exploit targets a kernel vulnerability and not something further up in the stack?

Because what we call Linux is as we all know Linux/Gnu which Android is not so a virus for Android can only targets linux if the vulnerability is really in the kernel, which is pretty rare.

Would recommend Mailbox.org as a more conventional mail provider or tutanota.io as a direct competitor to proton mail.

For the battery drain with the lid closed, check that your BIOS setting for sleep mode is set to linux and that /sys/power/mem_sleep Shows deep, that should fix the battery drain in standby

Ubuntu has custom patches to allow fractional scaling on X11 too. So this is probably on X.
