Public bug reported: 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.
