I often have an unexpected reboot when I leave my laptop alone for a while, when there's an external display connected on HDMI (I have the same issue with "HDMI over" USB-3).
The problem never happens when the laptop is not connected to an external display.
I only have this problem since I moved to Ubuntu 20.04. Never had it with Ubuntu 18.04 or Ubuntu 19.10.
I suspect it happens when the system goes to suspend mode.
- ASUS UX533FN
- NVidia GeForce MX150 - Intel mode
- HDMI monitor: any model, same issue
- System: Ubuntu 20.04 (up-to-date)
I have checked the kernel logs available with
dmesg but found nothing special so far. Actually I don't know where and what to look for.
Please guide me so that I can collect the appropriate logs and fix the issue! would you?
Or at least can you help me collect the right logs so that I can file a proper bug report on https://bugs.launchpad.net/ubuntu?
Thanks in advance!
