Public bug reported: Dear Sirs,
actually I'm using Ubuntu Mate 17.10 on a 64 bit machine. This is the output from "uname -a": Linux <myhostname> 4.13.0-36-generic #40-Ubuntu SMP Fri Feb 16 20:07:48 UTC 2018 x86_64 x86_64 x86_64 GNU/Linux I found strange behaviour after last grub2 updates, done automatically by using: "sudo apt-get update" "sudo apt-get dist-upgrade" Flashing bootmenu screen with black dots is really annoying (see screenshots). I also fear side effects. BIOS version is latest update. Grub2 is Package: grub2 Version: 2.02~beta3-4ubuntu7.2 What can I do? Kind regards Stefan This is my config: :~/Linux/Errors$ lspci -vvv 00:00.0 Host bridge: Intel Corporation 2nd Generation Core Processor Family DRAM Controller (rev 09) Subsystem: ASUSTeK Computer Inc.
