Then to use it: xrandr --output <monitor output> --newmode <modeline name> <modeline details from cvt> xrandr --output <monitor output> --addmode <monitor output> <modeline name> xrandr --output <monitor output> --mode <modeline name> Modeline name being whatever you like. You'll probably have to launch X with one of the monitors disconnected (as the bug may trigger before you can apply the modeline change). I believe the amdgpu DDX has support for specifying modelines, but I don't know the syntax off the top of my head.</pre> </div> <hr> You are receiving this mail because: <ul> <li>You are the assignee for the bug.</li> </ul> </body> </html>
