At console or XOrg without "xscreensaver Power Management" active, resume works fine. I tested 4.13.0-rc6: I executed "xset dpms force off"; then I executed "systemctl hibernate" from network. at resuming, the screen remains off, view dmseg output in attach. xrandr does not solve the situation: xrandr --output VGA-1 --off xrandr: Configure crtc 0 failed xrandr --output VGA-1 --mode 1024x768 xrandr: Configure crtc 0 failed Thanks</pre> </div> <hr> You are receiving this mail because: <ul> <li>You are the assignee for the bug.</li> <li>You are on the CC list for the bug.</li> <li>You are the QA Contact for the bug.</li> </ul> </body> </html>
