First Panel originally disappeared during monitor detection. 2015-11-25 10:08:09 +0000 1 1 4 Plasma plasmashell Panel 5.4.2 Arch Linux Linux RESOLVED DUPLICATE 355751 NOR crash 1.0 0 raquinio plasma-bugs-null notmart 0 oldest_to_newest 1551282 0 raquinio 2015-10-19 16:43:52 +0000 First issue was the following: The original panel (Panel 1) I edited was the stock panel. I plugged in another monitor (Monitor B) and that panel went to Monitor B. I tried using Display Configuration to change the settings to make the Monitor A the primary monitor, but that did not put Panel 1 back to Monitor A. I tried moving Panel 1 to Monitor A, but when moving from Monitor B to Monitor A, the panel disappeared. I created a new standard panel in Monitor A (Panel 2). Yesterday, I turn my computer on with both monitors on and found Panel 1 on Monitor B. I tried manually moving it to Monitor A and it worked. Today, I deleted Panel 2 (after making the same modifications to Panel 1, that I started making to this panel) and in doing so, DrKonqi showed up because plasmashell crashed. The desktop wallpaper also reverted to default. Here's the backtrace: Application: Plasma (plasmashell), signal: Segmentation fault Using host libthread_db library "/usr/lib/libthread_db.so.1".
