@Sebastian I provide more detail and info below Originally with the Dock at the bottom I could not get access to settings. I clicked settings and the cog appeared on the dock with an orange dot - but no window appeared - so no access to settings.
After getting the Dock back to the left side using the procedure that I highlighted in #27 above, I have done a lot more checking. Selecting displays in settings I find I supposedly have two displays, the one that is my laptop and an unknown display which does not actually exist i.e. 1 and 2 respectively (in that order). I plugged a standalone monitor into the port on the laptop and I then supposedly had three displays 1 3 and 2 in that order with display 2 showing unknown and not existing in reality. using xrandr it shows as follows (for two real displays and one non existing) (blurb removed for clarity) LVDS-1 connected primary VGA-1 connected HDMI-1 disconnected DP-1 disconnected VGA-1-2 connected In #27 and to get access to settings I used the link in 27# above and therefore VGA-1-2 was inserted in the command to remove the (at that time unknown to me a non existing) display (since then I have rebooted and it has reappeared but the Dock will remain at the side so I keep clear of the problem (I do not know enough to permanently remove VGA-1-2). For all I know this may be a problem specifically for my ASUS K53S laptop alone but my post pointed to a solution which all those above were seeking - so I thought I would help. -- You received this bug notification because you are a member of Desktop Packages, which is subscribed to gnome-control-center in Ubuntu. https://bugs.launchpad.net/bugs/1721637 Title: can't open system settings(Ubuntu 17.10), icon is visible but settings don't display Status in gnome-control-center package in Ubuntu: Incomplete Bug description: When i click on system settings, icon is displaying but settings window doesn't visible.
