[frenk]

I try to install the stable released Ubuntu 20.04 LTS (20.04 LTS) on Dell XPS 15 9560 using USB stick. The system power off at 6% of Check Disk. Also if I jump the check Disk system power off. The same USB disk work on a older Dell Latitude.

I cannot run this command because bug is during installation

I have the same issue on my Dell XPS 15 9560. As soon as the graphical interface would start, the system either shuts down or freezes completely.

However, it does work if I boot Ubuntu in "safe graphics" mode, but this way changing the display brightness and connecting external displays don't work.

It also shuts down while checking the disk.

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).

I'm having the same issue on my Dell XPS 9560.

[Attila T. Áfra (attila-afra)]

I guess a possible workaround could be is installing it in safe graphics mode, then blacklisting nouveau or installing the official NVIDIA drivers. I haven't tried this yet.

Same issue on my Dell XPS 9560.
I can confirm that using Safe mode I can boot into the installer environment. I haven't tried installing, yet.

Ubuntu 20.04 will install fine on the XPS15 9560. However you will need to set nouveau.modeset=0 and disconnect any monitor connected to HDMI.

Also after 20.04 is installed, you still cannot boot when a monitor is connected to HDMI. You will stay at the Ubuntu splash screen with the spinner spinning.
You can only successfully boot when the HDMI cable is disconnected,

It is a known issue of NOUVEAU.
Please use "safe graphics" to boot and install Ubuntu on usb disk.

After installation, please add "nouveau.modeset=0" in kernel cmdline if you still have issues.
Then install nvidia-driver-440, graphics and HDMI will be good.
