Device: Dell Precision 5540 (201904-26937)

1. Install Ubuntu 19.10.
2. Check 'Encrypt the new Ubuntu Installation for security' and 'Use LVM with the new Ubuntu Installation'
3. Check 'Overwrite empty disk space' in the next
4. Complete the installation and restart the device.
5. Sreen goes blank without splash screen
6. Screen still goes blank without splash screen after grub even though restart the system

Note:
system can boot normally seldom, the pass rate lower than 1/10

Thanks for your report.

The kernel refused to load the proprietary drivers with secure boot enabled. Could you please disable secure boot and tell if it boots?

Thanks

This issue does not occur on 20191017 daily-live.
Cannot be reproduced anymore whether secure boot enabled or not

I have a similar issue when I upgraded to Ubuntu 19.10. I was thinking it was a Grub2 issue.
