I tried booting in normal mode but with "nosplash debug" options, and it froze with lots of these messages:
nouveau 0000:01:00.0: fifo: runlist 0 update timeout nouveau 0000:01:00.0: tmr: stalled at ffffffffffffffff So it seems the freeze is caused by nouveau (the laptop has a NVIDIA GeForce GTX 1050). -- You received this bug notification because you are a member of Kernel Packages, which is subscribed to linux in Ubuntu. https://bugs.launchpad.net/bugs/1874624 Title: Unable to boot 20.04 LTS installer on Dell XPS 15 9560 Status in linux package in Ubuntu: Confirmed Bug description: I try to install the stable released Ubuntu 20.04 LTS (20.04 LTS) on Dell XPS 15 9560 using USB stick.
