I have an HP workstation z8 g4, with NVIDIA RTX A4000. It is a dual boot of Windows 11 and Ubuntu 20.04/18.04 (different settings were tried). As soon as an Nvidia graphics driver is installed and enabled in Ubuntu, abrupt distorted fonts, distorted displays, and eventually complete freezes occur in both Ubuntu and Windows. The problems in both OSes will not occur when the Nvidia graphics driver is disabled in Ubuntu and Intel’s graphics running.
