Computer freeze randomly when connecting multiple screens

[sza]

Sometimes, when trying to switch to a different terminal while the computer is at freeze(ctrl+alt+f2) I see the following output on the screen


I use Lenovo Thinkbook 15 4-Gen ( as mentioned in the picture).

I don't know where to start looking for the solution.
Any help would be highly appreciated!

First thing I noticed is that you don't seem to use the current standard *Ubuntu kernel for Kubuntu 23.10 : 6.5.0-10-generic.
And all messages have to do something with your iGPU ("i915").

Thanks, I figured out it is related somehow to my iGPU.
But I don't know where to start investigating my way to solve it.

As for my Kernel version, I've tried upgrading the kernel to the latest stable release hoping it'll solve the issue (it didn't ).

Thank you very much for your reply.
