Hi, Dear Pm-utils developers, I found a temporary method to resolve this bug.
My motherboard Asrock Z87 Pro3 has three display ports:D-Sub, DVI-D and HDMI. And my display AOC I2351Fe has two ports: D-Sub and DVI-D. When plug only D-Sub(VGA) line between Motherboard and display, every time resume from hibernate state will fail at display "no signal". When plug only DVI-D line between Motherboard and display, every first time resume from hibernate state will success, and the second resume from hibernate will fail at display "no signal". When plug both D-Sub and DVI-D lines between Motherboard and display, every time resume from hibernate will success. I resolved this bug. Another tips maybe helpful debug this bug for developers: Plug both D-Sub and DVI-D lines, when set display "Auto" accept D-Sub or DVI-D signal, resume from hibernate state, the first boot screen(Asrock logo appear) inform "DVI-D" or "D-Sub" signal used; After Grub menu, in the resuming screen(show N% resumed), inform "D-Sub" signal used; Inform "DVI-D" signal used when unlock login window appear. Plug both D-Sub and DVI-D lines, when set display only accept DVI-D signal, resume from hibernate state, the first boot screen(Asrock logo appear) inform "DVI-D" signal used; After Grub menu, inform "DVI-D, No Signal", the screen is black, can't see the resume progress; Inform "DVI-D" signal used when unlock login window appear. Although, I have resolved this question temporarily, but I don't know if it is harmful for my hardware with connecting motherboard and display using two lines above. And, I think maybe there are more and more Linux users will meet this question(multiple display ports on motherboard or display). Hopeful my information is helpful for fixing this bug. If need more detail information please tell me. -- To UNSUBSCRIBE, email to debian-bugs-dist-requ...@lists.debian.org with a subject of "unsubscribe". Trouble? Contact listmas...@lists.debian.org
