Then all screens remain off. I turned off/on the monitors and the signal briefly came on one of them but went back to black and then the laptop's display came back on. Now the xrandr output is Screen 0: minimum 320 x 200, current 2944 x 1080, maximum 8192 x 8192 XWAYLAND0 connected 1920x1080+0+0 (normal left inverted right x axis y axis) 310mm x 170mm 1920x1080 59.96*+ XWAYLAND2 connected 1024x768+1920+0 (normal left inverted right x axis y axis) 480mm x 270mm 1024x768 59.92*+ I'm attaching the dmesg output for that whole process.</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 QA Contact for the bug.</li> <li>You are the assignee for the bug.</li> </ul> </body> </html>
