Vanilla OS Installer not working

[jaunty adder]

Hello everybody!

I'm trying to install Vanilla OS on a Core 2 Duo E7500 with Radeon HD 7770 (Gnome automatically starts in X11 non-Wayland session)....

The system boot but the installer does not start (it is shown in the tray as already running but there is no window) because of which the installation is impossible....
I tried to run it through Ventoy and re-download the iso image. ... But the installer does not want to work at all ...

Does anyone have any thoughts on how to make it work well or install the system using an alternative method?

A note after a long time: I was able to solve the problem and the solution turned out to be simple and strange .... For some reason, the installer always starts on the second display and not on the main one, and therefore if someone has a dummy module connected (needed when you need to connect, for example, a tablet as a second display , and this module allows the video card to think that there is a second monitor), then it will face this problem because the installer will start on the second display and it will not allow itself to be moved... It's a strange moment if you think like that

Really weird that it starts on the second display, but wouldn't it be somewhere on the overview then?
