Recently installed a brand new copy of Linux Mint 20 Cinnamon and
suffered frequent freezes. The workaround suggested in comment #45 fixed
these for me. My current kernel is 5.4.0-47-generic, and I'm using a
Intel© Core™ i5-6500T CPU (2.50GHz × 4) with Intel Corporation HD
Graphics 530.

CubicSDR still triggers it for me even in 5.4.0-42.46, further a 5.8.0 mainline
kernel also suffers
the same. This was working for me until just a few days ago now it's not.

Intel GPU Hangs : random screen freezing
On my computer I use the workaround of changing the Xorg session from
modesetting to intel. To do this, firstly checking if xserver-xorg-
video-intel is installed and then I create the file
/etc/X11/xorg.conf.d/99-intel.conf with the following content:
Section "Device"
Identifier "Intel
I tested the test kernel 5.4 for about a day without issue
but all my computers using Intel GPU are using by default
kernel 5.5. I don't want to change that.

Tried the kernel by @lordbaco in #33 and it doesn't improve anything,
just in case it's useful.
My machine freezes up after a few hours, usually at a point where the
fans start to spin up under load. 2-3 times a day.
The symptoms are that the cursor starts to lag, massively, and the whole
@leozinho29-eu The kernel from comment 34 was just a plain 5.4.0-26
kernel, with nothing added to it (which wasn't intentional). Could you
reproduce the atomic update failure messages with an official Ubuntu
kernel installed, and then create a new launchpad bug for it?
Given that you encountered
For now (1 hour and 40 minutes running glxgears in one screen), the
system hasn't crashed. With the following command line:

029192618a7a ro quiet ro kvm.ignore_msrs=1 kvm.report_ignored_msrs=0
kvm.halt_poll_ns=0
@leozinho29-eu Please try this kernel:

Note that there really is only one package to install. That single
package contains everything.

comment 34 didn't pick up the change that was supposed to fix this bug's
crash... I'll rebuild it on my local machine for you.

@leozinho29-eu Can you add i915.enable_fbc=0 to the kernel command line
and see if that fixes the "Atomic update failure" messages? If it does,
then we'll know the problem is related to framebuffer compression.

I tested the kernel from comment 34 and my computer is no longer
crashing. With this kernel, it is possible to use default Xubuntu,
without changing Xorg session or xfwm4 vblank_mode.
What I noticed is that there are 1330 dmesg errors like:
[52999.965468] [drm:intel_pipe_update_end [i915]]
@lordbaco Please install this kernel and see if it still crashes:

So far no crash, freeze of any kind with Linux 5.5.13 compared to the
unstability of Ubuntu 20.04 with Linux 5.4 on Dell XPS 13 with 10th
