--- Comment #99 from madc...@atlas.cz --- I noticed something quite unusual this morning. I plugged my external display to a suspended laptop and woke it up. Initially the lock screen appeared only on the laptop's display which I assume is correct behavior. When I logged in, Plasma picked up the new screen but it left the panel on the laptop's display despite the settings looking all okay. I disabled the external display, expecting the main panel to disappear on the laptop's display and that's exactly what happened. Here's where things became interesting. 1) I ran "xrandr --output LVDS1 --off && xrandr --output LVDS1 --primary" which fixed the no panel glitch for me before. The display had gone black and didn't come back. 2) I "Fn+F7'd" the display back to life and enabled dual display setup in Plasma settings again. The panel was placed incorrectly this time too. 3) I ran "xrandr --output LVDS1 --off; xrandr --output LVDS1 --primary" to disable the LVDS1 output through xrandr again, curious what would happen (notice the ; instead of &&). However, my external HDMI display (connected to DP through an adaptor and identifier as HDMI1 in xrandr) went black instead. This time however it at least came back correctly. This almost makes me think that Plasma is not to blame here. It looks like X somehow confuses the outputs which makes Plasma place the panel incorrectly. -- You are receiving this mail because: You are watching all bug changes.
