I have a Asus monitor connected to my desktop computer. The screen resolution is 1920 x 1080 and it's connected with a DVI cable.
Everything works fine. When a power on the computer, I can see the login screen. But if I use Win + L to lock the screen, or if I switch between terminal (CTRL + ALT + F1 / F2...), the screen powers off and shows the message: No DVI signal.
However, it keeps running on the background. If I carefully type my password, I can log in. Or if I swith again to desktop mode (CTRL + ALT + F7) I can see again my screen.
My video card is "NVIDIA Corporation GT218 [GeForce 210]" on a i5-3470. I'm using Hera (5.1.3) No problems so far with it, besides these two weird things.
Thank you in advance!
