Not that I know, unless it's Xorg itself. I don't have any fancy DE, just X with FVWM. What I meant by the sentence you quoted is that I usually switch to HDMI (which is working), enter "sleep 10; xrandr....", then switch to DP and wait for xrandr to run. Running xrandr while the monitor is switched to HDMI, or when i'm switched from X to a different VT, won't work.</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>
