Problem with keeping window setting

Hi I hope this list can help me with an annoying problem. I recently changed my monitor on my stationary laptop to an other model. Since the change I have to configure the monitor settings in the control panel every time I boot. It forgets that the monitor shall be the primary display and it also forgets the screen resolution for the monitor. Which are the configuration files that KDE keeps this information? And why does it forget my settings? I'm running Fedora 30 on my Lenovo X201 laptop, which as written above is stationary, because the power button does not function any more, so only the power button on the docking station can power it up. The monitor is a ThinkVision connected to the docking station through a DVI to HDMI adapter. |< -- Med venlig hilsen/Regards Klaus Kolle Teknikumingeniør, B.Sc.EE., e-mail : klaus(a)kolle.dk Master of IT www : www.kolle.dk Asger Jorns Vej 17 Telephone : +4522216044 DK-8600 Silkeborg, Denmark "Man skal ikke tilskrive til sammensværgelser hvad der tilstrækkeligt kan forklares af inkompetence" Poul Henning Kamp Planlægning er tanker om noget man agter at gøre en gang i fremtiden, hvis omstændighederne tillader det.
