--- Comment #5 from Mik (e...@gmx.com) --- This new patch does not help = permanent dark state. The same undesirable effect is present, but increasing brightness has no effect now. Energy saving must be set on AC power and on Battery that way: Screen Brightness enabled with maximum level for both. Apply change removes the bug. Set that way, removing the PS reduces brightness to minimum and reconnecting it restores normal state. No need to increase it manually. Again, this is a one shot bug on boot or after restart. 20200630 Packages (23) breeze-git-5.19.80.r2009.g0fefe7fb-1 breeze-icons-git-5.72.0.r1576.gab758050-1 kcmutils-git-5.72.0.r409.g4ba2fe6-1 kcoreaddons-git-5.72.0.r989.g9748cbc-1 kdeplasma-addons-git-5.19.80.r8356.ge7ab2f301-1 kio-git-5.72.0.r4083.ge65ea9e8-1 kirigami2-git-5.72.0.r2249.gfd6e6138-1 knetattach-git-5.19.80.r7719.g8d926a3f8-1 kpty-git-5.72.0.r264.g690ee7c-1 ksshaskpass-git-5.19.80.r172.g01b5517-1 ksysguard-git-5.19.80.r3294.g8c4049fe-1 ktexteditor-git-5.72.0.r2378.g71b4295a-1 kwallet-git-5.72.0.r972.g032a2b8-1 kwidgetsaddons-git-5.72.0.r691.g1c648fb-1 kwin-git-5.19.80.r18115.g1b4c725d1-1 kxmlgui-git-5.72.0.r633.gd5d05d1-1 libkscreen-git-5.19.80.r1525.g1b78ba2-1 plasma-desktop-git-5.19.80.r7719.g8d926a3f8-1 plasma-framework-git-5.72.0.r15467.g7c4f5c5f1-1 plasma-nm-git-5.19.80.r2895.ga0455c31-1 plasma-wayland-session-git-5.19.80.r9170.g0ec7a3e2c-1 plasma-workspace-git-5.19.80.r9170.g0ec7a3e2c-1 powerdevil-git-5.19.80.r2321.gfcb26be2-1 With the new parameters (energy saving) removing/reconnecting the PS: journalctl -f -- Logs begin at Mon 2020-06-29 07:24:14 EDT. -- Jun 30 19:23:55 kk dbus-daemon[1044]: [session uid=1000 pid=1044] Activating via systemd: service name='org.gtk.vfs.Daemon' unit='gvfs-daemon.service' requested by ':1.38' (uid=1000 pid=1236 comm="/usr/lib/DiscoverNotifier ") Jun 30 19:23:55 kk systemd[849]: Starting Virtual filesystem service...
