If you’re ever present or have remote access to her network, make sure sshd is enabled, and try to SSH into it to see what happens.
Q’s:
- Is this a laptop or desktop?
- If Desktop, what kind of cable is the monitor connected with?
- See if you can get
dmesgoutput (needs to happen during the event, but the machine is still accessible - hence ssh above) - Does the monitor have its own power saving settings?















What kind of machine is this? If it’s something like an HP/Dell/Lenovo, it may have a boot blocker enabled somehow. It wouldn’t make a whole lot of sense since you managed to install Ubuntu, but they may possibly be creating different types of boot volumes.
You’d normally see a message like “HP Sure Start” at the boot screen, for example.
