Title:
Black/purple screen after booting Ubuntu
Status in gnome-session package in Ubuntu:

Status in gnome-shell package in Ubuntu:

Bug description:
Hi,
I am failing to boot into a freshly installed Ubuntu 18.04.5 LTS on my
ThinkPad-T460. When choosing the right bootloader in BIOS I get a dark
screen, Ubuntu is not booting (also after 15mins of waiting ...).
I first thought my issue would be a *Black/purple screen after you
boot Ubuntu for the first time* like over here:
https://askubuntu.com/questions/162075/my-computer-boots-to-a-black-
screen-what-options-do-i-have-to-fix-it
So I added ```ǹomodeset``` in the script executed before booting
Ubuntu. Interestingly I was able to boot and then made this change
persistent by updating the bootloader. I tried some more times to boot
and suddenly it stopped working properly (with same blackscreen as
before). I also took a look to the bootscript, ```ǹomodeset``` was
present there.
Then I played around with some other obscure suggestions like adding
```nouveau.noaccel=1``` instead of ```nomodeset``` and replace
```qiuiet splash``` by ```noapic noacpi nosplash inqpoll```, but
nothing gave me a soultion which did not get stuck with black screen
of death after some reboots.
I am a little bit clueless at the moment, so I have appended the uncompressed
logs in ```/var/log```, captured like in
https://wiki.ubuntu.com/DebuggingKernelBoot .
The files appended are from a boot that got stuck, I have killed my laptop
after 10mins of nothing happening.
Btw. I have a dual boot with Windows 10, but I do not know if this is
relevant for this issue.
Best
Alexander
