x11vnc server produces the error "### Error occured double check if the port is already used" regardless of the TCP port is being used or not. Changing the port to something other than the assigned 5900 is not helping either.

ElementaryOS 5.1 Hera

Is it possible to transfer the image through USB, similar to YamDisplay? Currently is very laggy when using WIFI only.

Hello this is not really an Issue I got it working, but` I wanted to share my Installation procedure because I got some "bugs" at the first try.

I love the VirtScreen program. It Still was a bit tricky to install on Ubuntu 18.10.
Just want to make clear what to do.

My Laptop specs:
Intel I5 with Intel HD Graphic
and Nvidia M150 Graphic card
on Ubuntu 18.10 with Gnome
Arandr installed

First problem no VirtualScreen1:
Tried with HDMI1-1 but it only duplicated my already used Monitor.

So created the /usr/share/X11/xorg.conf.d/30-virtscreen.conf file. Related: #16
(Terminal and sudo)

# Then configure intel internal GPU
Section "Device"
        Identifier "intelgpu0"
        Driver     "intel"
EndSection

And installed the latest x11vnc. Related: #19

Reinstall x11vnc and get it from Github
git clone https://github.com/LibVNC/x11vnc.git
cd x11vnc
sudo apt-get install automake autoconf
sudo apt-get install libvncserver-dev 
./autogen.sh
./configure
make
sudo make install
sudo apt-get install x11vnc

and now install the virtscreen package.
cd /whereEver/You/Downloaded/It/
sudo dpkg -i virtscreen.deb

and afterwards run it with in Terminal

virtscreen

Thats it.
I can even drag and drop my Windows to the Virtscreen.

Great tool.
Thank you for making this tool.

Are there any plans to do an ARM build? (at least for the Debian package)
It would be awesome to be able to use this on a Raspberry Pi and similar devices.

I firstly want to say thanks for making this. Here's my issue:

I was trying to sort out issue #19 for myself, but in the process of reinstalling I ended up with the following message when I launched the app:
`qt.qpa.plugin: Could not load the Qt platform plugin "xcb" in "" even though it was found.
This application failed to start because no Qt platform plugin could be initialized. Reinstalling the application may fix this problem.

Available platform plugins are: eglfs, linuxfb, minimal, minimalegl, offscreen, vnc, wayland-egl, wayland, wayland-xcomposite-egl, wayland-xcomposite-glx, webgl, xcb.

Aborted (core dumped)
`
How to fix this? one weird thing I did was edit the config.json file in the ./config/virtscreen folder.
The last line was about the version of x11vnc, and since I had installed 0.9.16, I changed it to that,
instead of 0.9.15.

I don't know what to do anymore! I really wanted to make this thing work ! Ugh.

AppImage is a universal Linux packaging.

What I tried so far:

• Just follow the README

sudo apt-get install virtscreen
sudo dpkg ...

I have already seen the icons. But whatever I click the icon or just type the command virtscreen --auto.

I am informed "Currently Wayland is not supported"
Sorry, I'm not so familiar with the Ubuntu. So I don't know what Wayland is. And what's wrong about virtscreen. I don't know what to do. Does this software support Ubuntu 18.04? It would be of great help if you could tell me what to do :)

Hi Mr. Bumsik, how we talk by mail, here i report my issue

How show the image, i don't have "VIRTUAL1" device in my laptop.

i only have HDMI-1 enable.

but, when i used this device the program show me this message

complete:

App window appears in the virtual screen on Surface Pro. It should appear on the primary screen.

On ubuntu budgie the icon and the gui are too big.

Hi,

I'm using Debian9 with the nvidia driver, and I can't get the VIRTUAL1 device.

I pasted the contents of lspci at https://pastebin.com/cd2YHVmm
and the contents of /var/log/Xorg.0.log at https://pastebin.com/upBwjhiy
(log shows a load of intel driver because I had it manually included in /etc/X11/xorg.conf.d/20-nividia.conf), but with same negative results

Any idea of what should I do in order to have a VIRTUAl display with this setup?

Thanks!

Anton

Using Linux distro PopOS 18.10 but getting error cannot detect system tray when running virtscreen in CLI.

Any help would be greatly appreciated!

Custom x11vnc arguments for advanced user.

In addition to my tablet I would love to add another VirtScreen to the session for my smartphone - either via GUI or Command Line.
An example on how to archive this would be really appreciated.

I have a monitor (HDMI-1) connected to my laptop, in addition to the built in display (eDP-1). When I run VirtScreen in this configuration, the virtual screen isn't correctly mapped - the VNC client shows half of the virtual screen and the rest of the output is black. Would it be possible to amend the virtual screen calculations to support systems with more than one physical screen?

Other than this VirtScreen works great, many thanks for your efforts!

Hello, my setup consists of a Ryzen CPU (1700 if that matters at all) and a Nvidia graphic card (Titan X Pascal), running Ubuntu 18.04.
like #16 I am not able to locate a virtual output, but unlike #16 I do not have an intel / AMD integrated GPU in my CPU, so the only thing I can rely on is the Nvidia driver.
I have tested a few things before posting here, including:

1. Try to add Option VirtualHeads to Nvidia driver in the file under xorg.conf.d, while resulting in failing to load the driver
2. Edit the /etc/X11/xorg.conf display section, as suggested by someone (I can't seem to find the post now), and nothing really happens and xrandr still doesn't have a VIRTUAL1 output.

I will try to use the dummy monitor solution when I get some more time and hopefully can report how it works for this application. But for now, I would like to see if there is anyone who already has got anything done before?

I can clone, but not expand the monitor.
How to solve this? I would like to have on my tablet an extended monitor from my fedora 30.
Can you help me?

When I'm in the GNOME activities overview (kind of like Mission Control or Exposè in macOS, if you don't know GNOME) and I grab a window, GNOME freezes. I can get it to unfreeze by pushing escape, but I can't move my window around.

This is an issue because it forces me to use keyboard shortcuts to move windows between workspaces (which, personally, I do a LOT) and either manually drag windows between monitors on the desktop or use keyboard shortcuts.

Extra info:
I am using a Lenovo Thinkpad T420 with an i5-2520M @ 2.5GHz, 2 core hyperthreaded, and Intel HD graphics 3000.
I'm running Manjaro GNOME, with everything (except Dropbox) up to date at the time of writing.

My VNC client is an iPhone 6S 32GB, iOS 13.3.1 on Verizon with VNC Viewer V3.8.42034 . I'm going over my home wifi, which is enterprise grade network gear.

I literally downloaded VirtScreen today, so it's AppImage V0.3.1 .

According to a discuss in Arch linux forum, Arch Linux python-pyqt5 package does not provide metadata of PyQt5 package. So VirtScreen need to skip checking PyQt5 package version.

I am using Fedora 29 and I'm currently getting a "Currently Wayland is not supported" error. Should I uninstall it and replace with something different? Or when will it be supported?

/tmp/.mount_VirtScc66ZQr/usr/share/virtscreen/env/bin/python3: symbol lookup error: /tmp/.mount_VirtScc66ZQr/usr/share/virtscreen/env/lib/python3.6/site-packages/PyQt5/Qt/plugins/platforms/../../lib/libQt5XcbQpa.so.5: undefined symbol: _ZN20QPlatformIntegration11screenAddedEP15QPlatformScreenb, version Qt_5_PRIVATE_API

I would like to use VirtScreen to turn my iPad Mini 4 into a secondary monitor but the VIRTUAL1 option is not available to choose from.

Laptop Specs:

• 64-bit

Tablet Specs:

• iPad Mini 4
• iOS 11.4.1
• VNC Viewer app by RealVNC (https://www.realvnc.com/en/connect/download/viewer/ios/)

What I tried so far:

• Rebooted the devices
• Reinstalled the .deb package (version virtscreen_0.2.4-1_all.deb)
• Reinstalled x11vnc (version 0.9.13-2)
• Different settings, devices and VNC Clients/Viewer
• It's the same issue on Android 8.1 and iOS 11.4.1 (only connect and mirror works)

I can connect and mirror my laptop screen to my iPad.
How to enable the VIRTUAL1 option to make it into a secondary monitor?

Any help is really appreciated. (Can anyone confirm that it works on Ubuntu 18.04.1?)

I cannot seem to make a virtual screen i am on arch running kernel 5.0.8

Like I mentioned in the title. I have installed your program and it is amazing, I wonder if there is a way to just refresh the mouse position so that it could reflect on the VNC client, which could really help development.

When starting virtscreen, GUI or terminal, I get an error in the app that reads "There is no primary screen detected. Go to display settings and set a primary screen.". However, once I click OK, the message goes away, and there is nothing open to change a setting in. Can you give me direction on this? Thank you.

I'm running the latest update of GalliumOS.

There is a nice reference:

• https://github.com/tectonic-typesetting/tectonic/pull/67/files

Hi, I am trying to run VirtScreen on an openSUSE pc running on an 8-core AMD FX-8350 with integrated graphics.

Here is my graphics card as detected by inxi -G:

Graphics:  Device-1: Advanced Micro Devices [AMD/ATI] Caicos [Radeon HD 6450/7450/8450 / R5 230 OEM] driver: radeon v: kernel
           Display: x11 server: X.Org 1.20.7 driver: radeon resolution: 1920x1080~60Hz
           OpenGL: renderer: AMD CAICOS (DRM 2.50.0 / 5.5.6-1-default LLVM 9.0.1) v: 3.3 Mesa 20.0.0

I have read both issue #16 and issue #23 and tried all suggestions, but did not get the VIRTUAL1 device.
Trying to use one of the other devices (HDMI-0) I got the same error as in #14.

I understand that, presently, there's no supported way to run VirtScreen without an Intel or nVidia gpu, but I am opening this bug nonetheless because there's no other open issue in the tracker regarding the radeon driver, so this is a means to track the problem and push for a solution.

The radeon options are described here. There's unfortunately no support for the VirtualHead option or something similar.

If it is of any use I can post the output of my 'xrandr --verbose' and/or 'lspci'.

Seems as though install works fine with Yaourt, but fails with Yay (which is also a reasonably popular AUR helper).

Here is the output from Yay:

After installing it with:
$ yaourt virtscreen

For some reason TopbarIcons Redux stopped working for me and now i can't acces the GUI mode.

The VNC Server component runs fine, but the virtual display is not created nor shows up in the GNOME display settings. No error messages are given. VIRTUAL display option is not available, so HDMI-1 is selected.

• VirtScreen 0.3.1 (via .deb)
• Ubuntu 18.04.2 LTS
• GNOME 3.28.2

• NVidia GTX960M installed (but not working to run X for some reason, so intel is in use)
• DisplayLink Driver installed

Instead of using a .png it will be idea if it could be replaced by virtscreen-symbolic.svg.

This will make the app look more native on all Linux distros.

Currently the program outputs quite dirty message. It should output messages that everybody would understand.

Installed the package from AUR (virtscreen 0.3.1-1), but when I try to run it it gives me a "Cannot detect system tray on this system" error. I'm running OS 4.17.19-1-MANJARO
with x11 not wayland.

Starting the program with the log=INFO flag results in an empty log.txt file.

I installed from the .deb and when I run it, it says it's running and will keep running in the system tray but I don't see a GUI anywhere on my desktop.

Qt 5.12 will be released around December.
I'm going to use this as soon as it is released because Qt 5.12 adds ES7 support in QML! I will rewrite my QML code to ES7.

Other than ES7, I will examine if there is any other great features I can use for VirtScreen, especially Quick Controls 2.

I just following your 'Installation - Debian(Ubuntu)' and 'How to use' steps, but there is a problem that I cannot solve.

When I press "Enable virual screen" button in app, then alert following message.

No virtual screen selected.
Go to Display->Virtual Display->Advaced
To select a device.

But in my ubuntu 18.04.1, there is no display tab such as virtual ~~.

How could I solve this problem?

Every time I close the virtual screen, part of the virtual screen appears on the primary monitor and the system stops responding. I use distro Linux Mint 19.
