I forgot all about this bug until the tag of cscc was added. As reported previously the machine is now running 18.04.2 LTS fairly well. All updates including kernels have been done,
Graphics now state IntelĀ® Ironlake Mobile and the /etc/default/grub file contains the line GRUB_CMDLINE_LINUX_DEFAULT="quiet splash" So all is well with the world. -- You received this bug notification because you are a member of Desktop Packages, which is subscribed to lightdm in Ubuntu. https://bugs.launchpad.net/bugs/1764087 Title: Wrongly boots into low graphics mode using kernel 4.13.0-38 (mostly works with 4.13.0-37) Status in X.Org X server: Won't Fix Status in lightdm package in Ubuntu: Confirmed Status in linux package in Ubuntu: Confirmed Status in xorg-server package in Ubuntu: Confirmed Bug description: Description: Ubuntu 16.04.4 LTS Release: 16.04 Lenovo T410 with VGA compatible controller [0300]: Intel Corporation Core Processor Integrated Graphics Controller [8086:0046] (rev 02) Booting from latest kernel ThinkPad-T410 4.13.0-38-generic #43~16.04.1-Ubuntu SMP Wed Mar 14 17:48:43 UTC 2018 x86_64 x86_64 x86_64 GNU/Linux goes into low graphics mode and also effects wi-fi connection insofar as it does not connect to my router.
