Have phone screen off while mirroring on computer #175

WrathX · 2018-06-15T16:35:53Z

It would be nice to have the screen mirroring on like it does but have the phone screen off, only showing on the computer. Would need to be able have the screen awake all the time while plugged in as well. Great job on this so far, just got it recently and it's very responsive. I use it at work all day. Thanks.

alambike · 2018-06-17T11:16:08Z

👍 Disable phone screen will be a nice feature .

rom1v · 2018-06-17T19:40:21Z

Yes, that would be great. But I have no technical solution. See reddit comment.

WrathX · 2018-06-18T15:20:39Z

Ok thanks for the response. Anyway of having the screen switch to stay awake when using this? Currently every time I use this I have to go into developer options and switch on stay awake while charging. I don't really want it staying awake if I am charging my phone overnight while not using this so I have to go back in every time after using scrcpy and switch stay awake off. If possible it would be a nice convenience. Thanks for this, I've been using this for a few days now at work. Since Oreo came out Sidesync hasn't been working so this was a great find. thumbs up

rom1v · 2018-06-18T15:38:08Z

Anyway of having the screen switch to stay awake when using this?

Currently, no. It's probably possible to wrap scrcpy with a script that enable/disable "keep screen on".

(Just for info, a right click switches the screen on.)

WrathX · 2018-06-18T15:56:43Z

Ok thanks again for the response. Ya I was using the right click to turn on but I have to unlock the phone everytime so it would be better to have the screen awake all the time in my case. I use my phone a lot during the day to contact my drivers (I'm in dispatch) so unlocking the phone everytime gets clunky. Thanks for whatever you can do.

bonrry · 2018-06-18T16:21:33Z

Just an idea... If the server has enough privileges as shell, and has a chance to detect disconnection and do something before dying, it could set the global setting key "stay_on_while_plugged_in" to value 7 upon starting, and reset it just before dying? Same for brightness setting (if a global one exists?). That would "automate" the described behavior... Le lun. 18 juin 2018 à 17:56, WrathX <notifications@github.com> a écrit :

bypassing the lock screen, that would be quite the exploit in the android os (unless u purposely put it there).
if there is no lock screen on, maybe remove the unlock animation, turn screen brightness down to about 200 nits...very low , keep screen on while charging, have double tap to wake mappable to any key eg. double shift.
have a copy of your android device in a virtual machine.
dont know if this is even possible just throwing some ideas out there

cleberOliva · 2018-08-09T19:57:36Z

What's the version of downloaded scrcpy? If it's below the current then download the actual version and run on terminal the command scrcpy -h, there's a session of shortcuts in the end. To turn on/off screen of phone, type Ctrl + P.

Currently, no. It's probably possible to wrap scrcpy with a script that enable/disable "keep screen on".

(Just for info, a right click switches the screen on.)

I was able to do this with a script combined with Tasker and AutoRemote installed on the phone. Tasker sets the display timeout. I also have it set screen brightness to minimum.

I would like to turn off the screen on the phone but can't do it without blanking scrcpy as well.

What did you use for the trigger? I'm looking to do something similar.

rom1v · 2019-03-15T19:22:46Z

Oh, I investigated a bit tonight, in fact it's quite easy:

IBinder display = SurfaceControlgetBuiltInDisplay(0);
SurfaceControl.setDisplayPowerMode(display, POWER_MODE_OFF);

I have a working PoC.

The power button reenables the screen (which is good for the physical button, but is also an issue with the simulated power button on scrcpy starting and on right-click/Ctrl+P, e.g. when the screen goes black after timeout, a right-click also reenable the device screen).

I will probably work on this soon if I find some time.

rom1v · 2019-03-15T19:24:55Z

If you are interested, here is my quick test: screenoff.

cotfas · 2019-05-12T14:08:41Z

I am also interested when the screen goes off, in Vysor there was implemented when this happened and I click on any key it will turn on the screen. Will be nice to have this feature.

rom1v · 2019-05-12T14:10:37Z

I click on any key it will turn on the screen. Will be nice to have this feature.

If the screen is off, a right-click turns it on.

cotfas · 2019-05-12T14:13:02Z

It works, thanks!

xeon927 · 2019-05-13T05:24:34Z

+1 - have tried the test and it works just about perfectly (Galaxy Note 9) - only thing I've found is as stated above - if screen turns off, when it comes back on, phone display also does too.

Would also love to see if it's possible to include a --no-screen flag to choose at launch if you want screen off or not.

Add two shortcuts: - Ctrl+o to turn the device screen off while mirroring - Ctrl+Shift+o to turn it back on On power on (either via the POWER key or BACK while screen is off), both the device screen and the mirror are turned on. <#175>

rom1v · 2019-05-31T21:15:01Z

Implemented on dev by 12a3bb2.

Press Ctrl+o to turn the device screen off while mirroring, and Ctrl+Shift+o to turn it back on.

Would also love to see if it's possible to include a --no-screen flag to choose at launch if you want screen off or not.

I decided not to add such an option, because as soon as the display is off (timeout or explicit power off), we need to "power on", causing both the device screen and the mirror to be turned on. Thus, the command line option would not be "persistent", and this would be confusing.

npes87184 · 2019-06-01T04:33:28Z

I have tested this feature.

There is a problem I find, after switch off and on sometimes, the device screen cannot be turned on.

I am using HTC One M8 with android 6 and OnePlus 6 with android 9 for testing.

rom1v · 2019-06-01T05:48:58Z

@npes87184 Anything in adb logcat?

Does it switch on with the power button?

(if both the device screen and the mirror are black, you need to POWER ON)

rom1v · 2019-06-01T12:39:12Z

Maybe Ctrl+Shift+o should power on instead when screen is off?

npes87184 · 2019-06-01T13:48:28Z

@rom1v

The problem is device screen is black and the scrcpy works. In this time I cannot turn on screen by Ctrl + Shift + o

There are some logs here:

It seems the first time failed, it will show:

WrathX · 2019-06-01T14:09:02Z

Is there a release to test this out?

rom1v · 2019-06-02T19:22:22Z

@npes87184 I have no idea about the cause, and I cannot reproduce :(

char101 · 2020-03-30T08:05:51Z

And while keeping the screen turned off, we can use this batch file to prevent the OS from sleeping

@echo off
setlocal
set APP=scrcpy-noconsole.exe
set APP_DIR=C:\scrcpy

:scrcpy
pushd %APP_DIR%
start %APP% -b 16M -S
popd

rem generate mouse event while scrcpy is running
:loop
adb shell input keyevent mouse
timeout /t 5 /nobreak > NUL
tasklist /FI "IMAGENAME eq %APP%" 2>NUL | find /I /N "%APP%" > NUL
if "%ERRORLEVEL%"=="0" goto loop

:end
endlocal

rom1v · 2020-05-27T16:29:27Z

I just reactivated the shortcut (Ctrl+Shift+o), in practice it works: dcde578

@npes87184 can you still reproduce the issue?

npes87184 · 2020-05-28T03:15:14Z

I would test it after 6/3.

iamthekings5 · 2020-05-30T12:59:50Z

My screen seems to get permanently dimmed if I use Ctrl + Shift + O (turning it off and on will make it remain dimmed, only can fix with restart).

npes87184 · 2020-06-04T12:50:05Z

I tested it on my samsung galaxy note10+. It worked!

Since v1.15, the shortcuts are bound to Alt by default, so it's Alt+o.
