Seeing the "0mm x 0mm" part in the xrandr output makes me think that this may be a problem with obtaining the EDID information from the monitor. To check this, one would need Xorg.0.log with Option "ModeDebug" "true" in the "Device" section, and the output of `xrandr -verbose`.
Since the computer is no longer available for testing, I guess there is not much we can do unless someone else with a Lenovo ThinkCentre M55 comes around (?) -- [Q965] "No screens found" https://bugs.launchpad.net/bugs/282609 You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. -- ubuntu-bugs mailing list [email protected] https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
