A fresh installation of the Focal daily image dated 20220831 fails to start the graphical environment when using the nouveau drivers and I'm only able to log in on the console. The system under test is using QEMU w/ GPU passthrough and an NVIDIA GeForce GTX 650 device.
The same issue happened with the 20.04.4 installation media however in that case I tried to install the NVIDIA drivers but installing the drivers did not work.
