If I run the following without a sleep, or a short sleep, between the two xrandr calls it will often not bring the screen back up, but if I up the sleep time to 5 seconds or more it seems to be pretty reliable. Note the following also works without having to set the lower resolution first as I had previously thought was required. xrandr --verbose -q -d :0 --output DP1 --off sleep 5 xrandr --verbose -q -d :0 --output DP1 --auto --right-of HDMI2 Occasionally I'll get an error like the following when running the commands: X Error of failed request: BadMatch (invalid parameter attributes) Major opcode of failed request: 140 (RANDR) Minor opcode of failed request: 21 (RRSetCrtcConfig) Serial number of failed request: 43 Current serial number in output stream: 43</pre> </div> <hr> You are receiving this mail because: <ul> <li>You are the QA Contact for the bug.</li> <li>You are on the CC list for the bug.</li> <li>You are the assignee for the bug.</li> </ul> </body> </html>
