Ubuntu laptop won't recognize external HDMI monitor with VGA adapter for more than a minute
I have a Lenovo laptop with a Nvidia Geforce GT 730m video board, which have an external HDMI port. I also own an external Samsung monitor, which I don't know the model of. It only has VGA input.
To solve that issue, I bought a VGA to HDMI adapter, like this one:
I'm using Ubuntu 18.04.1 LTS, and this is a fresh install (I formatted to try to fix the issue). My problem is: The laptop isn't recognizing the HDMI monitor for more than 1 minute.
However, there is one small catch to this issue: Right after I plug the HDMI in, it is recognized, and I can use it for some time. After sometime passes, it seems to reconfigure and the monitor is gone. If I try to xrandr while it's working, it also loses configuration and is gone. The same happens if I try any configuration with Displays or Nvidia XServer, it just disappears when the Displays software loads
I tried almos everything I could find, but nothing worked. Including:
xrandr --addmodeand some variations- Using NVidia latest drivers
- Using Nouveau latest drivers
- Formatting the OS
- Logging in with
nomodesetandnoedid(the combination of both rendered no interface, not even in the notebook screen)
My Kernel version is 4.15.0-42-generic

Yes, I do get a picture on display for some time after I plug it in. Configuring makes it go away

If the adapter isn't active (and thus requires power), it very likely won't work unless it's specifically suitable for some non-standard "VGA-over-HDMI" output mode. Does a normal HDMI (or DVI) monitor work?

The monitor stops working after some time it is plugged in, and then xrandr gives meHDMI-1 (disconnected)

If I reconnect it works again, but ytring to verify anything withxrandrmakes it go away before any output in xrandr
