I was on NVIDIA version 410 and decided…ahh why not upgrade to the latest driver. I had a look in my Additional Drivers under Software & Updates and decided to download and install version 430
Since this update and after a reboot, the following bug exists:
As the screen under power settings is set to blank after 5min (which always has been this way by the way!)
The screen does not wake up after i move the mouse or press keys on the keyboard. It says “cable not connected”
I have to then press the reset button on my PC since there is NO way to get my screen back.
I know that this happens for a fact as i attached a second screen simulaneously on the DVI port and after i try waking up the screen, it does not wake up the original screen (since it says no cable connected) it only wakes up this second DVI-port screen.
As i said, and im going to repeat this:
This has never happened on version 410.
This has happened and was tested on version 415, 418 AND now 430!! (i thought at least by version 430 this problem would be picked up by someone, but clearly not)
Can you please revert back to whatever changes you did so that the screen can wake up properly from “blanking” because this is very annoying if i want to upgrade to a newer display driver.
