I have received equipment, at my educational center, with the following characteristics:

**AMD RYZEN 5 2600 Six-Core Processor x64 16 GB RAM Graphics: 22P1W 1023MB NVIDIA GeForce GT 710 Motherboard: AB350M PRO4-F, A320M PRO4-F OOSS: Windows 10 Pro Education 64/bit and EducandOS **

I inserted a USB with Ubuntu 22.04 LTS image, it is created with Balena Etcher.

The installation wizard takes a long time to start and a graphic error appears (this equipment has an additional graphics card and it does not use the one that comes with the motherboard)

Can someone help me with a suggestion?

Thanks in advance

I have installed tigervnc in Ubuntu 20.04.4 but it does not work well.

My unit file is the following one (I want to run like as service): (/etc/systemd/system/vncserver.service -rw-r--r-- 1 root root 309 Mar 17 22:00 vncserver.service)

[Unit]
Description=TightVNC server
After=syslog.target network.target

[Service]
Type=forking
User=root
PAMName=login
PIDFile=/root/.vnc/%H:1.pid
ExecStartPre=-/usr/bin/vncserver -kill :1 > /dev/null 2>&1
ExecStart=/usr/bin/vncserver
ExecStop=/usr/bin/vncserver -kill :1

[Install]
WantedBy=multi-user.target

I run the following commands:

sudo systemctl daemon-reload

sudo systemctl start vncserver.service
Job for vncserver.service failed because the control process exited with error code.
See "systemctl status vncserver.service" and "journalctl -xe" for details.

When I check it the following message appears:

sudo systemctl status vncserver.service
