It seems to not login automatically or get X session after installing Nvidia-driver

[Kevin Yeh]

During SRU testing, I found some machines kept failing to run switching graphic card test.
According to the output from the test run, those machines seem to not login automatically or can't get X session somehow.

Now I can't check the status of machines directly, but my guessing is base on the output from our test case, it showed "Can't open display :0" and "Gtk couldn't be initialized. Use Gtk.init_check() ".

I met this issue on there different machine which I can get log from them so far, there are other machines have this issue but I can't get the log.

Our testing always use ubuntu-driver install to install nvidia-driver.

Hi Kevin, the 520-open driver does not support running a desktop environment yet. Can you attach the output of the following command, please?

ubuntu-drivers debug

Hi Alberto
Please find the log and console-log in our test job in the attachment.

The problem here is that ubuntu-drivers-common in Focal is too old, and does not include code to handle the -open driver series. This needs an SRU.
