I believe I have a workaround to this. I had exactly the same on 17.10 on an Acer Aspire One, reinstalled 16.04 and still had it. I also had it clear up if the machine suspended and resumed.
It looked to me like it was related to the grub splash screen, just based on it messing up before the GUI starts and the portion of the screen that got corrupted. I changed the grub config in /etc/default/grub to the following... GRUB_CMDLINE_LINUX_DEFAULT="" <- edit the existing line GRUB_GFXPAYLOAD_LINUX=text <- add this line Then updated grub with sudo update-grub and rebooted. Now it has a 100% text boot and no corruption of the screen. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1728565 Title: Desktop (screen) corrupted after upgrade to 17.10 To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu-mate/+bug/1728565/+subscriptions -- ubuntu-bugs mailing list [email protected] https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
