After upgrading from Ubuntu 23 to 24 LTS, I'm experiencing strange behavior with random reboots (black screen and reboot).

What I know:

  1. It only reboots if Discord is running.
  2. It reboots after 20-30-40 minutes.
  3. Everything works fine on Ubuntu 23.
  4. A full Ubuntu reinstall (with disk formatting) does not solve the problem
  5. I found something similar here (Ubuntu 24.04 shuts down after a few minutes) but it did not solve the problem

Any ideas?

I had a similiar problem that was annoying me once a day or two. There is a system level problem. It is related either your GPU drivers or some of applications installed via Snapstore.

The First (easier solution): If you use snap-store and using Discord on your system it is likely the problem is related with a bug on AppArmor. solution is here:

sudo snap connect discord:system-observe

if you want to learn more about the cause then check this: Issue related AppArmor

or

in GPU case follow the steps below:

check the latest updates if it started after an update:

cat /var/log/apt/history.log

in my case these are the changed

  • libgl1-mesa-dri

    • libglx-mesa0

    • libegl-mesa0

    • libglapi-mesa

    • libgbm1

    • libxatracker2

    • mesa-vdpau-drivers

all graphic related updates. (I use Nvdia drivers too)

I've checked the available packages in my computer.

apt-cache madison libgl1-mesa-dri libglx-mesa0 libegl-mesa0 libglapi-mesa libgbm1 libxatracker2 mesa-vdpau-drivers

then downgrade them 24.0.5-1ubuntu1

sudo apt-get install libgl1-mesa-dri=24.0.5-1ubuntu1 libglx-mesa0=24.0.5-1ubuntu1 libegl-mesa0=24.0.5-1ubuntu1 libglapi-mesa=24.0.5-1ubuntu1 libgbm1=24.0.5-1ubuntu1 libxatracker2=24.0.5-1ubuntu1 mesa-vdpau-drivers=24.0.5-1ubuntu1

if you like you can prevent them to upgrade onwards:

`sudo apt-mark hold libgl1-mesa-dri libglx-mesa0 libegl-mesa0 libglapi-mesa libgbm1 libxatracker2 mesa-vdpau-drivers`

I am having the same problem on my fresh install of Ubuntu 24.01.1, I got Nvidia GTX 1080Ti and using the 'nvidia-driver-550 driver' option under 'Software and Updates' -> 'Additional Drivers'.

I already know discord might be the problem, so I don't install it. I also think Chrome might be the issue, so I disable Chrome 'Use graphics acceleration when available'.

If I still randomly reboot, I will use another Nvidia driver, probably version 535 under 'Software and Updates' -> 'Additional Drivers'. If that still doesn't work, I'll use the 'Ubuntu on Wayland' option in the login screen.
