Public bug reported: (This is probably related to bug 1816860, but with different hardware and a different appearance, so it is filed separately.)
Using the levovo Helix 2 attached to its Pro keyboard, it is not possible to activate the monitor as attached. The monitor is attached with a mini-DP-to-HDMI cable to the monitor (SONY), and is - in this case, contrary to the bug mentioned before - detected as can be seen by xrandr. But then it gives up after some time (see attachment of System Settings started from CLI and Xorg.log: $ tail /var/log/Xorg.0.log [ 970.977] (II) modeset(0): Modeline "1920x1080"x0.0 138.12 1920 1968 2000 2052 1080 1083 1089 1122 +hsync -vsync (67.3 kHz eP) [ 973.083] (II) modeset(0): EDID vendor "LGD", prod id 1121 [ 973.083] (II) modeset(0): Printing DDC gathered Modelines: [ 973.083] (II) modeset(0): Modeline "1920x1080"x0.0 138.12 1920 1968 2000 2052 1080 1083 1089 1122 +hsync -vsync (67.3 kHz eP) [ 1009.658] (II) modeset(0): EDID vendor "LGD", prod id 1121 [ 1009.658] (II) modeset(0): Printing DDC gathered Modelines: [ 1009.658] (II) modeset(0): Modeline "1920x1080"x0.0 138.12 1920 1968 2000 2052 1080 1083 1089 1122 +hsync -vsync (67.3 kHz eP) [ 1099.146] (II) modeset(0): EDID vendor "LGD", prod id 1121 [ 1099.146] (II) modeset(0): Printing DDC gathered Modelines: [ 1099.146] (II) modeset(0): Modeline "1920x1080"x0.0 138.12 1920 1968 2000 2052 1080 1083 1089 1122 +hsync -vsync (67.3 kHz eP) (and so it continues).
