Foliate doesn't open in WSL

[nixl0]

I've installed Foliate through Flatpak on WSL with Ubuntu 20.04 distro, but it doesn't open. Something like gedit works fine.

Shows this set of messages instead, after which nothing happens:

nlx@hewlettpackard:~$ flatpak run com.github.johnfactotum.Foliate
EGLDisplay Initialization failed: EGL_NOT_INITIALIZED
Can't find bus: Cannot autolaunch D-Bus without X11 $DISPLAY
Can't find bus: Cannot autolaunch D-Bus without X11 $DISPLAY

(com.github.johnfactotum.Foliate:2): Gtk-WARNING **: 21:22:52.718: cannot open display:
nlx@hewlettpackard:~$

Believe this is more a problem with WSL.

Now, Foliate is working perfectly in new WSL version. Follow this tutorial, or the shortened steps below.

Prerequisites: You must be running Windows 10 version 2004 and higher (Build 19041 and higher) or Windows 11.

1. Enter this command in an administrator PowerShell or Windows Command Prompt:

   wsl --install -d Ubuntu

2. Then, restarting your machine.
3. Open Ubuntu, set up your Linux username and password.
4. Update:

   sudo apt update && sudo apt upgrade

5. Install Foliate via PPA:

   sudo add-apt-repository ppa:apandada1/foliate
   sudo apt update
   sudo apt install foliate

6. Open Foliate from a shortcut via the Start Menu.

I had the same problem, and I've solved it now. This is because of a lack of a driver for vGPU. To run Linux GUI apps, you should first install the driver matching your system. Just follow this tutorial.
