Xorg.0.log shows this line while switching from a text VTY to display :0 (EE) intel(0): sna_mode_shutdown_crtc: invalid state found on pipe 0, disabling CRTC:21 I've already tried to wake up the monitor via xset dpms to no avail. I noticed that if the monitor is already powered up while resuming from suspend to memory it will exit from standby mode, otherwise it'll stay "no signal/power save" until X is killed.</pre> </div> <hr> You are receiving this mail because: <ul> <li>You are on the CC list for the bug.</li> <li>You are the assignee for the bug.</li> <li>You are the QA Contact for the bug.</li> </ul> </body> </html>
