@yasser WOL needs the MAC addresses of the PCs to work. So, you have to supply that info in the configuration.

Which version of Veyon are you using? You can try to disable capturing of layered windows in the configurator in the VNC server settings (select builtin VNC server if not selected) within the Service page.

Welcome to the Veyon forum! If users have admin privileges they usually can change any setting of any application so of course this applies to Veyon too Without admin privileges you can neither run Veyon Configurator nor change the settings in the registry.

Today I worked on improving this so in upcoming 4.1.5 release the toolbar only appears after a delay of about 500 ms and the animation for appearing/disappearing is much faster now so everything should be much more usable now. A test build (4.1.4.10) is available at https://github.com/veyon/veyon/releases/download/v4.1.4/veyon-4.1.4.10-win64-setup.exe If you like the improvements please consider to make a donation to the Veyon project, see https://veyon.io/get-involved/ for details

Hello I launched a test in a room of my school and it seems to be OK thank you for your work some suggestions for devolppement: features of italc that were useful: when several rooms were set up, we could choose directly a room to display in one click, [image: 1539350203310-a7f416af-7c9f-4785-af01-d8aca106576a-image.png] When a click held on a thumbnail image of a computer, an enlarged vision of the screen was proposed. Good luck and keep it up Fred

Tested 4.1.4 still the same problem, when I click the test access button and type "asdf" so not a valid user I still get user has access to control master...

Can you please try version 4.1.4?

@tobydox In fullscreen Demo mode. Thnks for reply.

It could be an issue with the builtin VNC server. You can try to disable the Enable capturing of layered windows option in the service / VNC server options. Altering the other options could be worth a try as well. Which update interval have you configured on the master side?

Yes there should be no limit if you have enough RAM, see http://docs.veyon.io/en/latest/admin/installation.html#hardware-and-software-requirements for details. If you encounter CPU usage issues you can increase the thumbnail update interval in the configuration.

So, to make sure I understand correctly, an incremental upgrade is ok? Like, I can install 4.1.3 to the master, but not to the clients and it will be ok? Does 4.1.3 need to ever be installed to the clients for any improvement? Thanks!

Hi everyone, It a painful, but i manage to get my keyboard back. It wasn't working in safe mode, I try the repair option, it took some times but my laptop is working again. I haven't get the chance to re-install Veyon on it because it start working just in time for class. I'll try to "clean" the laptop before trying to re-install Veyon. Thanks again for the help. 3 hours later I can confirm that the laptop is working as a charm and I was able to install Veyon on it.

Hi Toby, Thanks for your reply, but I feel stupid, I was using the veyon-ctl command to reset config within a regular Command Prompt window ... (I still don't get why I need admin privilege when I'm already admin). Opening a Command Prompt as Administrator was what I've miss earlier to reset the config and push the new one. All your suggestion were done it was Windows that trick me (again) Sorry for the useless noise. and thanks again for your reply.

You can use the silent installation method as described at https://docs.veyon.io/en/4.1/admin/installation.html#automated-installation-silent-installation

Still unable to solve the problem. it should be noted that this problem happens on windows 10

Thanks for reporting this issue. We'll add the missing code for disabling power saving mechanisms.
