Bug ID: 492176
Summary: Clamshell mode does not wake up monitor
Classification: Plasma
Product: kwin
Version: master
Platform: Fedora RPMs
OS: Linux
Status: REPORTED
Severity: normal
Priority: NOR
Component: general
Assignee: kwin-bugs-n...@kde.org

Target Milestone: ---
SUMMARY
In my laptop when I use clamshell mode with external usb mouse, keyboard and
screen my system goes to sleep, when I wake it up by opening the laptop, the
apple display will wake up and turn on the external screen. If I, however, set
my laptop to not sleep and only leave the turn screen off setting, when I wake
up the computer again, my external monitor will not wake up like it did when
the laptop came out of sleep. Is there a way to find out if there is some
command or parameter that sleep mode sends and we could implement that for the
turn screen on part?
STEPS TO REPRODUCE
1. Place laptop in sleep mode after X amount of time
2. Keep laptop in clamshell mode
3. Wake up laptop from sleep by opening laptop
4. External monitor will wake up as well (Apple Display in this case)
Second workflow
1. Place laptop in "Do nothing" mode after X amount of time
2. Keep laptop in clamshell mode
3. Wait until external monitor turns off after a period of inactivity
4. Move the mouse or type on the keyboard to wake up the display
OBSERVED RESULT
Display does not wake up
EXPECTED RESULT
Display should wake up any time the screen has been off due to inactivity
