Suspend problem with Samsung NP535

view story

https://bbs.archlinux.org – Just like shipa, I've had the same suspend issues regarding the black screen on my Samsung NP535U3C. After resuming, the computer turns on but the screen does not (tested, since I've been able to reboot the computer with "sudo reboot" in a terminal). This occurs with both the open source drivers and with Catalyst, and with either "systemctl suspend" or "pm-suspend". I've googled for many hours, but none of the fixes have worked for me.Here is some information about the computer: glados-potato% cat /proc/cpuinfo processor : 0 vendor_id : AuthenticAMD (HowTos)
