Why does my login screen look broken?

gs flag

Occasionally, when I restart my computer and boot ubuntu (I have dual boot with Windows 10), my Ubuntu login screen looks fragmented. I'm using Nvidia graphics driver version 470 (proprietary), and I have secure boot disabled. I can still type in my password (though I can't see what is happening) and it will display my desktop like normal after I login.

Additional Details I can re-create this issue by doing the following:

  1. Boot into Windows
  2. Suspend Windows (Put to sleep)
  3. Resume into Windows
  4. Reboot computer
  5. Boot into Ubuntu

Any additional information on what conditions appear to prompt this would help a great deal. Intermittent problems are the hardest to solve. Does this happen on cold starts or only restarts, does it happen in recovery mode, do you have a splash screen on your normal login, etc.?

You right. I just added some additional details. Essentially, I can re-create the problem if I reboot after hibernating/resuming from Windows.

Disable fast start

  • boot into Windows
  • open the Power control panel
  • choose change what the power buttons do
  • choose change options that are unavailable
  • uncheck fast startup
  • close the Power control panel

Don't do this if you use hibernation

  • open an administrative command prompt window
  • type powercfg /h off

Check your C: drive

  • type chkdsk /f c:
  • approve to run chkdsk at next reboot
  • reboot into Windows to let chkdsk run on drive C:

Check your Ubuntu partition

  • boot to a Ubuntu Live DVD/USB in “Try Ubuntu” mode
  • open a terminal window by pressing Ctrl+Alt+T
  • type sudo fdisk -l
  • identify the /dev/sdXX device name for your "Linux Filesystem"
  • type sudo fsck -f /dev/sdXX, replacing sdXX with the number you found earlier
  • repeat the fsck command if there were errors
  • type reboot

Most people don’t grasp that asking a lot of questions unlocks learning and improves interpersonal bonding. In Alison’s studies, for example, though people could accurately recall how many questions had been asked in their conversations, they didn’t intuit the link between questions and liking. Across four studies, in which participants were engaged in conversations themselves or read transcripts of others’ conversations, people tended not to realize that question asking would influence—or had influenced—the level of amity between the conversationalists.
