In my case, (my original report at https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1744065 ) I went from...
intel-microcode: Installed: (none) ...to... intel-microcode: Installed: 3.20180108.0+really20170707ubuntu17.10.1 ...and it made no difference when booting linux-image-4.13.0-31-generic Still don't know if it's only graphics. I get no login screen and just a black screen on resume from hibernate. When experiencing the black screen I can't use CTRL+ALT+F1 to switch to a terminal. The fan doesn't spin up. I don't have a CAPS LOCK light, so I can't tell that way. Simply a non-responsive machine with a black screen. I think it's the same as the OP, given the kernel version it appeared, fact it's a Lenovo Thinkpad X230 and apparently identical behaviour. If there are steps I can take to help with triage happy to do so, but I currently have no means of investigating further, given there is no way to even tell the machine is running or not. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1743094 Title: [regression] hibernation (freezes on resume) since 4.13.0-25.29 To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1743094/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
