Absolute newb here, having problems with my first install. I've made a bootable USB stick with the installer for Ubuntu Desktop 18.04.3. When I boot on the stick, I get the simple text menu, allowing me to try or install Ubuntu. If I choose Install, the signal to my screen dies. Instead, I tried the option to Try Ubuntu without installing, and it took me to the GUI without any problems.. From there, I chose the option to install Ubuntu to a local SSD, and the installation process seemed to complete without any problems. When re-booting on the disk I just installed to, I again loose the signal to my monitor, and have nothing but a blank screen. Any help or suggestions would be much appreciated.
