Why does my login screen look broken?

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

Solution 1:

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
