GUI doesn't show up, app automatically closes on clicking "Open VirtScreen" from tray about virtscreen HOT 13 OPEN

Hi .. i use to have the same problem to open the GUI of virtscreen

msdk@seth:~$ virtscreen 
libGL error: MESA-LOADER: failed to open crocus: /usr/lib/dri/crocus_dri.so: no se puede abrir el fichero del objeto compartido: No existe el fichero o el directorio (search paths /usr/lib/x86_64-linux-gnu/dri:\$${ORIGIN}/dri:/usr/lib/dri, suffix _dri)

and I found this solution on stackoverflow.

The problem, for me, is with the libstdc++.so.6. This file is located in /usr/lib/x86_64-linux-gnu/libstdc++.so.6 on my system. To know where to find this file I suggest to run the following command :
find / -name libstdc++.so.6 2>/dev/null

which resulted with files from snap and /usr/lib/... (I'm use /usr/lib/) & I added the export LD_PRELOAD to my .bashrc file and it's working fine.

export LD_PRELOAD=/usr/lib/x86_64-linux-gnu/libstdc++.so.6

If I test on my terminal...

msdk@seth:~$ export LD_PRELOAD=/usr/lib/x86_64-linux-gnu/libstdc++.so.6
msdk@seth:~$ virtscreen 
qml: Loader Status Changed. 1
qml: Unloading ApplicationWindow...
qml: Loader Status Changed. 0

and voila .. .I hope this helps

Hello. The same problem, but on Linux Mint

from virtscreen.

Yep, not working here on Kubuntu 21.10

from virtscreen.

Same for POP OS 22.04. Here are some additional details:

Hi @msdkone, about this

which resulted with files from snap and /usr/lib/... (I'm use /usr/lib/) & I added the export LD_PRELOAD to my .bashrc file and
it's working fine.

I am running a .sh file with the export command followed by virtscreen, which is working like a charm . But I couldn't understand how to add in .bashrc. Can you explain more details about it?

from virtscreen.

LD_PRELOAD=/usr/lib/x86_64-linux-gnu/libstdc++.so.6 ./Virtscreen.appimage

works for me

from virtscreen.

export MESA_LOADER_DRIVER_OVERRIDE=i965; ./VirtScreen.AppImage

works for me

from virtscreen.

bashrc is executed only in interactive shells. If you are going to call Virtscreen.appimage from you desktop environment, you should put

export LD_PRELOAD=/usr/lib/x86_64-linux-gnu/libstdc++.so.6

in your $HOME/.profile

Similar problem on Ubuntu 22.04 with nouveau driver.
LD_PRELOAD trick doesn't help.

According to what I see, it has a problem with the Nvidia driver.

Are you using Wayland or Xorg?
If you use Wayland, try using Xorg.
Wayland, being newer, is not yet compatible with all applications.
hope this helps
