Hi,
A few months ago the behaviour of my Fedora XCFE desktop changed when I leave it to idle.
I have 2 screens attached to an nVidia GTX1050Ti card, and I use nVidia's own driver. As usual, after a period of idling the screensaver kicks in. This used to leave both screen turned on, but not displaying my desktop. I could touch a key, get an unlock window up, enter my password and resume work. Now, one of the screens says "no signal" when the screensaver engages, and turns off after a timeout. I have to turn it back on manually, which is a little annoying. The real problem is that when I turn it on, the nvidia driver doesn't recognise the presence of the screen and start using it. The screen continues to say "no signal". If I enter my password, the second screen works OK. I can then run the display configuration utility, disable the first screen, reenable the first screen, and it displays the correct desktop again. Does anyone know if this new behaviour is due to some configuration parameter I can alter?
Regards,
Steve
