Re: Invisible bar

Avoid floating which sometimes goes wrong for newly created bars.  Try some fixed position first, then switch to floating.   Floating remembers last position which might be off screen to left or right or below on laptop screen.  You can look at screen coordinates in text file if you want to see. 

 Lap top config just meant  the config file pproconf.pcf  for the laptop.
 

 Instead of playing with position, you can also try ctrl-right clicking visible old bar and selecting show info for all bars which will show screen positions of all cls being shown as bars.    You should be able to move to main display by selecting and clicking the button which does that.
