Public bug reported:
I have a laptop with Intel Core Ultra 7 and Intel Arc Graphics. I'm using
Ubuntu (include your Ubuntu version here).
When I connect an external monitor via HDMI, it initially works fine. After a
while of use (sometimes during video, sometimes while idle), the external
monitor image freezes — it stops responding completely.
The built-in laptop display continues working normally.
The frozen monitor still shows the last frame/image.
If I unplug the HDMI cable, the apps/windows that were on the second
monitor move to the main screen and continue working fine.
This seems like a graphics driver or power management issue specific to
Intel Arc.
Steps to reproduce:
Connect HDMI monitor
Use system normally (move apps, play videos, leave idle)
After a while, external monitor freezes

Intel Core Ultra 7
Intel Arc Graphics (integrated GPU)
