Found a solution / workaround: Followed instructions here (https://linuxcritic.wordpress.com/2015/03/29 /change-screen-brightness-in-lxde/) and that dims.
# show connected monitors $ xrandr -q | grep connected # outputs: # LVDS-1 connected primary 1366x768+0+0 (normal left inverted right x axis y axis) 344mm x 194mm # dims screen to 50% $ xrandr --output LVDS-1 --brightness 0.8 So it seems on this machine one just needs to map xrandr commands to the function keys instead of what it's doing by default. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1685620 Title: Screen flashes continuously when brightness set to lower than 100% using fn keys on Samsung NT200B5C-STW/R laptop running Lubuntu 17.04 x64 To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1685620/+subscriptions -- ubuntu-bugs mailing list [email protected] https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
