guiscrcpy won't connect to phone

[xbfrog]

I am using Ubuntu 20.04 fully updated and Samsung s10 phone also updated. Guiscrcpy 3.9.2 just updated today from 3.9.0. I installed Guiscrcpy from snaps. Enabled permissions in the app and enabled developer mode in Samsung. It worked for a few days. This morning turning it on brought up the Gui but no tools or directional pad. The gui said can not find any devices. Ubuntu see the phone and can transfer files no issues. I tried restarting the gui with no change. The progress bar each time stops at 5%. Checked debugging, on, checked permissions, on. So I uninstalled guiscrcpy and reinstalled, no change. rebooted Ubuntu, no change. Rebooted phone, no change. Tried to start it a couple more times and then the gui with tools appeared with directional pad. The progress bar now says 100%. And the message in the center of the screen says checking device connection. Still no phone screen. So I tried another cell phone Droid Maxx, turned on developer mode, same issue, can not find device. But again Ubuntu sees it. At this time I reconnected the samsung, gui comes up with tools and directional pad but no phone screen. Each time the gui progress bar goes to 100% twhen it seems to get farther while the white banner in the middle of the gui says checking device connection. I'm stuck as how to proceed.

@xbfrog Can you connect your device to the PC and then run this in the terminal

guiscrcpy.adb devices -l

Even if ubuntu detects it, for adb (the tool used to connect to mobile and send commands to the device) might not have detected it. Thats why you are getting error

[xbfrog]

i ran guiscrcpy.adb devices -l the result was: List of devices attached

RF8M64D8N0J            device usb:2-3 product:beyond1qlteue model:SM_G973U1 device:beyond1q transport_id:3

dj@greenfrog:~$ List of devices attached

Command 'List' not found, did you mean:

  command 'mist' from snap mist (master)
  command 'gist' from deb yorick (2.2.04+dfsg1-10)
  command 'dist' from deb mmh (0.4-2)
  command 'dist' from deb nmh (1.7.1-6)
  command 'hist' from deb loki (2.4.7.4-10)

See 'snap info <snapname>' for additional versions.

dj@greenfrog:~$ RF8M64D8N0J            device usb:2-3 product:beyond1qlteue model:SM_G973U1 device:beyond1q transport_id:3

@xbfrog can you now try running

export GUISCRCPY_DEBUG=True
guiscrcpy

and then send me the output, also please check if your device is getting detected now

GUI still says checking device connection

@xbfrog, Seems like its only a problem with the message. Please see

guiscrcpy.scrcpy

And please let me know of the output of the same

Please ignore the message, (I forgot to put a CONNECTION COMPLETED Message in that box and thats why you have confusion. I am sorry about that)

Are you able to see a window of your mobile ? Thanks for your testing

no, i do not get phone screen

[srevinsaju]

@xbfrog How did you get scrcpy v1.14 ?
Have you installed scrcpy before in any other way?
Please provide me the output of

which scrcpy
ls /usr/local/share/scrcpy
echo next
ls /usr/share/scrcpy

[xbfrog]

as you mentioned it now, i did try to install scrcpy via terminal before i found it in snaps. terminal install was unsuccessful.
which scrcpy
/snap/bin/scrcpy
dj@greenfrog:$ ls /usr/local/share/scrcpy
ls: cannot access '/usr/local/share/scrcpy': No such file or directory
dj@greenfrog:$ echo next
next
dj@greenfrog:~$ echo next ls /usr/share/scrcpy
next ls /usr/share/scrcpy

[srevinsaju]

thank you; Its because you installed scrcpy from another source; Hence guiscrcpy is conficting with your installed scrcpy.
You can uninstall scrcpy by

sudo snap remove scrcpy

And it will then solve your problem

Its not a bug with guiscrcpy. You can still use scrcpy by

guiscrcpy.scrcpy

Remove all installation of SCRCPY or use the AppImage of guiscrcpy as an alternative

[srevinsaju]

Can you also execute

ls /usr/share/scrcpy

Which distro are you running @xbfrog

[xbfrog]

Thank you for finding the issue. I"m glad its not a bug, I would have never found it on my own. Guiscrcpy is the best app for its kind out there across any platform. You are doing a great job. I look to seeing more great features

[xbfrog]

i'm running Ubuntu 20.04

[srevinsaju]

Great! Alternatively, if you do not want to uninstall scrcpy, you can try out the AppImage from the releases which will work without configuration;

Thank you
