I am running Fedora 26 64 bit with the latest updates. I noticed that every time I put the system to sleep, and subsequently wake it up, the system is stuck with a black screen (the monitors turn on but immediately go into stand-by mode, they don't show the "no signal" message though) and I can do nothing, I can't even change to a TTY. To partially solve this I can just unplug a monitor (from the graphics card) and plug it again, the video returns and I can use the computer except that all graphics are messed up, the cursor is a big 256x256 square filled with white noise, and many other parts of the UI are filled with this white noise as well. Sound is sometimes broken too, the pavucontrol mixer says it should recover automatically or I could run start-pulseaudio-x11. Of course running it doesn't help. Going back to runlevel 3 and then again to runlevel 5 (via systemctl isolate runlevelX) seems to solve the graphics part, but it doesn't work for when audio breaks too. In all cases the real solution is to restart the system (reboot).

This happens regardless if I have two or just one monitor connected at the moment I put it to sleep, and it responds on anything that triggers a change in video mode i.e. either connecting or disconnecting any monitor. I don't know if this happens if I just use the built-in graphics (the VGA or DVI port directly from the motherboard) or with the card disconnected or disconnected, since removing the NVIDIA drivers is always a PITA.

My configuration is as follows:

• Intel Core i5-4440


• NVIDIA GTX 1050 (Gigabyte)


• ASUS H81M-E Motherboard


• I have 2 SSDs connected to the 2 SATA III ports and


• 2 regular HDDs connected to the remaining 2 SATA II ports


• 500 W PSU


• Dual 1080p monitor setup, one (Acer) connected to the VGA output using a VGA-to-DVI-D cable and the other (Benq) connected to the DVI-D output using a DVI-D-to-DVI-D cable
