Comment 2 for bug 1770108

I am facing this same problem with 4.13.0-41-generic as well as 4.13.0-43-generic. When I boot in either of those kernels, I first get a black screen with a dialog box saying: "The system is running in low-graphics mode - your screen, graphics card, and input device settings could not be detected correctly. You will need to configure these yourself."

When I click OK, it gives another dialog box where I choose "Try running with default graphical mode". Then Ubuntu Desktop boots properly, but the network (wireless) symbol is there but empty. No network connection.

I tried disabling Networking or Wi-fi, and enabling them again, but nothing changes.

I have attached the output of the apport-collect 1770108 run on a terminal. I ran the command on the 4.13.0-43-generic kernel first, and then rebooted into 4.13.0-39-generic kernel and ran it again. In the 4.13.0-43-generic kernel, it does not do much but print errors to std_error since it cannot connect to the Internet. It works in the 4.13.0-39-generic kernel and opens the launchpad webpage.
