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. ** Attachment added: "output of apport-collect 1770108 command" https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1770108/+attachment/5147998/+files/apport-collect1770108.txt -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1770108 Title: No wifi in 4.13.0-41-generic To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1770108/+subscriptions -- ubuntu-bugs mailing list [email protected] https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
