Re: The nightmare of Intel Integrated GPUs under Linux in general and Debian in particular
Interesting.... very interesting.

The same as yours:
VGA compatible controller: Intel Corporation HD Graphics 530 (rev 06)
in a I5-6500 CPU.

You are lucky. Very lucky. For the last 5 years this have been a
constant pain, one problem after problem. When a problem got fixed by
a new kernel a new problem appeared, for every single kernel version I
tested. It even affected my ability to get the work done: yesterday I
had 3 complete system freezes in less than an hour. But I use KDE, I
use 3D acceleration, and I use programs who uses 3D acceleration so I
constantly hit these kind of bugs.
One of the less buggy kernels for me in the one in Debian Buster
(4.19.0-8-amd64). Hangs are not so frequent with this kernel but the
text consoles are corrupted:

This capture is from my own computer:
https://bugs.freedesktop.org/attachment.cgi?id=143903
The problem was solved in later kernels but the fix never reached Debian Buster.

I'm using a desktop, so power saving is not a problem. Of course one
of the multiple tests I made was disable GPU power saving, limit the C
states...all the proposed workarounds that works for some users but
none of them worked for me.
I will try kernel 5.5 when available in unstable and if I still get
hangs, I will try a different graphics card.
Thank you.
