Android tablet or phone display on Linux Manjaro Laptop with SCRCPY

On one laptop it works.
On the important one it does not work yet. I do hope it almost will !

Done so far : # pacman -S adb, # pacman -S scrcpy. In the tablet : Enable USB debugging on Android : works. adb devices and scrcpy commands do work. I did learn these commands to stop and start adb : adb kill-server; adb start-server. They do work. Responce ! They did help on the first laptop !

Tablet is recognized by “$ adb devices”

[MiniHowTo] Present code or command output

Note: Grave accent (or, backtick) characters are used. :eyes:

For inline code or to show a single command:

  • please follow this simple example: code here.

For multi-line command output:

  • place text beween two rows of three (```) backtick characters to form a scrollable text box, or …
  • use the </> button in the Compose window to achieve the same result.

The empty row between these rows of backtick characters is where to paste any multi-line command output (such as inxi).

An example of a pre-formatted text enclosure:

What is a Quark?

A. In Physics, an elementary particle and fundamental constituent of matter. 
B. A character from the Star Trek: "Deep Space Nine" television series.
C. A soft, creamy, usually unsalted cheese traditional to central Europe.

Hallo soundofthunder, I did read it. I do want to update the text. I dont find the Edit button !?
How to update my text ?
Thanks

That’s because you’re still only a TL0, and as such, the grace time for editing your own post has expired. :wink:

Just post a followup here on the thread. :wink:

Why is it so tough to add a post ? My text is rather well considered, with good info, good readable !???

I’m afraid I don’t understand the problem. :man_shrugging:

Discourse — the forum engine — maintains a grace time for edits on people’s posts, and especially so depending on people’s Trust Level. Your Trust Level is still 0, because you have not posted much yet and have not visited the forum frequently enough yet. So your grace time has expired, and thus you can no longer edit your post.

Ergo, if you have any new information to add, just post it here below on the thread. :man_shrugging:

Android tablet or phone display on Linux Manjaro Laptop with SCRCPY

Next trial with better formatting (I do hope) >:-)

On one laptop it works. On my old laptop 2011 with Linux Mint 20.3 it works !

On the important one it does not work yet. I do hope it almost will !

Done so far :

# pacman -S adb
# pacman -S android-tools
# pacman -S scrcpy.

  • adb devices and scrcpy commands do work.
  • I did learn these commands to stop and start adb : adb kill-server; adb start-server. They do work. Responce ! They did help on the first laptop with Linx Mint 20.3

I did, and hope it will be better now. And will take time to the responses to anwser them fast !

What is it set to?
echo $XDG_RUNTIME_DIR

printenv output will also contain this variable - at least it should

Is the desktop environment different between the one machine where it works and the one where it doesn’t?

for me it is:

echo $XDG_RUNTIME_DIR
/run/user/1000

but this is not on Manjaro at the moment

I have no experience with scrcpy but I do have a fair amount of experience with adb and the tools.

On Arch based systems - it may be necessary to add yourself to the group adbusers to be able to access certain parts of the adb protocol (an acronym for Android Debug Bridge - if I recall correct).

sudo gpasswd -a $USER adbusers

Thanks to you. I did it, but no solution yet !

I did take the time to read this manual : Users and groups - ArchWiki. So good !

The group adbusers did not exist yet.
So I did made a copy of /etc/group, as user root
# cp /etc/group /etc/group_2026_0119

$ sudo gpasswd -a $USER adbusers

$ cat /etc/group | grep $USER

I did try again to init scrcpy with
$ adb devices
$ scrcpy
answering the pop-ups on the tablet
result :

$ scrcpy
scrcpy 3.3.4 <https://github.com/Genymobile/scrcpy>

How to continue ?

Thanks anyone in advance !

The user group is created when you run

sudo pacman -Syu android-tools

Just for the sake of verification.

I just connected my Samsung Galaxy A53 to my desktop using scrcpy

So it must be something on your end that is blocking.

I quickly revisited you initial topic - there is no package named adb and all your commands is only --sync - could it be that your lack of using -Syu update has caused a partial scenario?

This would - at least partly - explain why you are getting errors.

I think you may benefit from doing a full system sync

sudo pacman -Syu

Then restart - and use your default user account to connect.

Maybe my eyes are playing tricks on me (I’ve only just started sipping my first coffee of the day), but I cannot find any system information in this topic. I can’t even find the desktop environment being used. Is it GNOME; XFCE; Plasma; or something else?

Even the user profile lacks this basic information. Please update your user profile by visiting this page: Forum Profile Preferences

More importantly, please provide the output of:

inxi --filter --verbosity=8

or the short form (preferred):

inxi -zv8
Running `inxi` in `chroot`

Note that any code or command output (such as inxi output) should be placed within a scrollable pre-formatted text enclosure according to forum guidelines.

See here for instructions: :point_down:

For inline code or to show a single command:

  • for example, typing: `code here` will display the text as code here.

System information is vital to working out this issue, due to scrcpy requiring different setups depending on whether the display is wayland or x11.

If you have some morbid fear of providing accurate system information, then at least let us know what display you are running by posting the output of:

echo $XDG_SESSION_TYPE

The reason this information is required:

No available video device could be due to you running scrcpy, which defaults to x11, on a wayland display.

scrcpy/FAQ.md at master · Genymobile/scrcpy

Client issues

Issue with Wayland

By default, SDL uses x11 on Linux. The video driver can be changed via the SDL_VIDEODRIVER environment variable:

export SDL_VIDEODRIVER=wayland scrcpy

On some distributions (at least Fedora), the package libdecor must be installed manually.

See issues #2554 and #2559.

KWin compositor crashes

On Plasma Desktop, compositor is disabled while scrcpy is running.

As a workaround, disable “Block compositing”.

I could be barking up the wrong tree as I’ve never used scrcpy, however confirmation of the display being used could help fix the issue, or it may eliminate the display as being the cause of the issue.

Hmm - I am running Wayland only - I did the above test without knowing about possible limitations with Wayland - no issues.

That’s good - as I said, I’ve never used the application.

Still, some system info from the OP might be helpful.

Indeed - I am beginning to think it is Nvidia related.

@HansDeHekker please provide the requested system information - otherwise we just punching holes in the dark.

Thanks again. I’m familiair with “pacman -Syu”. Will execute it now again once more.

# pacman -Syu
:: Pakket-databases synchroniseren...
 core is bijgewerkt
 extra is bijgewerkt

 er valt niets te doen

Fully upgraded. Nothing to do !

Thank you for providing this info - it may be important which GPU is active when you try to run scrcpy.

We now know that your system is a laptop with Intel iGPU and Nvidia dGPU.

It seems your primary GPU at the time of pulling the system info is the Intel GPU

This tells that you have more than one user registered on the system.

You will need to verify which one is active when you try to run scrcpy and if necessary add the user to adbusers group.
