--- Comment #6 from jamese <james.el...@gmail.com> --- Here's some further debugging on this one. Config "ae115bc4aa5f4ce701f72fc9e25f01cb" is the MST setup with Laptop Screen + DP1-1 (master) and DP1-2 (slave) - I chmod'd this to 0400 so it couldn't be written by any user. It still has the width/height in it from the last working setup. Config "1818bd03d6fa05c34acde90101a5d242" is the Laptop with HDMI plugged in. I plugged in DP cable and the bug reproduces. I've got kcmshell5 kcm_kscreen running and will attach output although nothing appears in the output when I activate the DP setup. I unplug the DP cable and no change to the desktop occurs. Laptop screen is still split in half & external DP screens are not active at all. I then switch inputs on DP1-2 to HDMI and plug in the HDMI cable, this brings the desktop back with HDMI output enabled and visible along with Laptop Screen. But: * HDMI (HDMI2 in kscreen) says "No available resolutions" and the display is slightly fuzzy. It also appears to be at a lower bit depth * After some repositioning of the HDMI screen and hitting apply, the resolution slider appears with 1920x1080 enabled and the bit depth / fuzziness issues disappear. I then unplug the HDMI cable to see if I can get DP displays back and the Laptop screen goes black then comes back and freezes although the mouse cursor works. Can't do anything here. Plugging the DP cable in does not bring the desktop back, nothing in kcmshell output. Can't run kscreen-bug here as only mouse works. Plugging the HDMI cable back in re-activates the desktop! Other weirdness that occurs here: - is when I plug the HDMI cable in, all the windows either from Gtk (Shutter) or KDE apps (e.g kate) disappear under the panel when maximised, even though the panel has "Always Visible" set. This is a common problem for me at the moment with KDE multi-screen setup. - when I initally plug in the DP screens they come up greyed out, showing the wrong aspect ratio although the slider says 1920x1080. If I fiddle with the slider the greyed out screens resize correctly. Configs and outputs will be attached. -- You are receiving this mail because: You are watching all bug changes.
