- I dual booted Ubuntu 18.04 and Windows 10 following this video: https://www.youtube.com/watch?v=u5QyjHIYwT
- For 2-3 days, I was able to boot into Ubuntu 18.04 (default) or Windows 10 as needed. The GRUB screen gave me the option of which OS to choose from. Everything worked perfectly.
- Today I booted Ubuntu, coded for a bit and then restarted the system to boot into Windows 10.
- The blue windows appear (as do the circular loading dots) but the system hangs on a black screen.
- Restarting the system to enter Ubuntu again, I find that the system hangs on a purple screen.
Ubuntu 18.04 info:
- Only loads from recovery mode (only Linux 5.0.0-23-generic works and not 5.0.0-37)
- Using UEFI
- Using NVIDIA driver metapackage from nvidia-drive-435 (proprietary, tested) – recommended driver
Windows 10 info:
- Only loads in safe mode (with networking or without).
- Using UEFI
Points of interested:
If I switch the 435 driver to ‘nvidia-driver-430 (proprietary)’, then even recovery mode doesn’t boot. In order to boot with 430, I had to do the following: 1) Press ‘e’ at the GRUB menu before selecting ‘Ubuntu’ 2) Add the following to the line that starts with ‘Linux’: ‘acpi=off’
Note: If I added ‘nomodeset’ Ubuntu still wouldn’t load.
System specifications: 1) CPU = AMD Ryzen 7 3700X 2) Graphics Card = EVGA Nvidia GeForce GTX 1660 TI Ultra Gaming Edition 3) MB = Asus PRIME X570-P
Note that I’m a novice Ubuntu user, so I’d really appreciate pretty streamlined instructions (as painful as that may be!). Thanks in advance!
EDIT: I decided which driver to use by going to Software & Updates -> Additional Drivers -> Using NVIDIA driver metapackage from nvidia-driver-435 (proprietary, tested)
EDIT 2: The problem appears to be driver related. Here is a temporary fix: Open Windows 10 in safe mode, uninstall Nvidia display driver, restart and I can open Windows 10 normally. I then run Nvidia GeForce Experience and install the same driver again (the most updated one). Then, Ubuntu also boots normally. However, I've been able to replicate the problem (sometimes) with the following sequence: Computer turned off -> Load Ubuntu -> Restart -> Load Windows -> Shut down -> Load Ubuntu -> Restart -> Load Windows (now hangs on black screen) -> Restart -> Load Ubuntu (now hangs on purple screen).
This seems like a convoluted sequence of a events, but it's what triggered the issue twice. I also triggered it once in another way, but I can't recall the sequence exactly. It involved going between Ubuntu and Windows multiple times though.
Any thoughts to resolve this? I notice that I get a few error messages before Ubuntu hangs for the first time. I check the boot log, but I can't find the messages I saw. Is there any way to find the error messages that can appear before the Ubuntu log in? (The log would only be 3-4 lines long).
