19.04 installer hangs on installation complete dialog

[David Ober]

Installed version 19.04 on a Lenovo P1 laptop and when the installation Complete dialog came up I hit the restart button and the system froze. I then have to hard power down. At this point it boots to a login prompt. I login but there is no desktop after ten minutes or more finally reinstalled. On reinstall again same freeze at install complete but this time after several minutes the desktop did finally show up. Only difference on the installs was first time I selected the update wifi and other drivers click box and second time I did not.
BIOS N2EET38W
CPU i7-8850H

It should be caused by the nouveau driver for Nvidia card.

A workaround is to add 'nomodeset' when boot up, and after that install the nvidia-driver-390, after reboot, this issue should be gone.

Also it would be better if we could fix it in nouveau.

@Bin, @Anthony, Can we have the fix before 19.04 GA? Thanks.

The suggest from Bin Li fixed the problem.P1, X1 Exteme and P52 worked fine after we implemented the fix.we may need a permanent fix from within the OS in the near future ?...

Still broken in Ubuntu 19.04...With this Install nomodeset did not work.David had to blacklist the nouveau module
Are we going to get a permanent fix ?.

@Vamshee
Can you provide more details what you did and what did not work?

[AaronMa (mapengyu)]

Use this ISO:
http://cdimage.ubuntu.com/daily-live/current/disco-desktop-amd64.iso

with nomodeset in kernel cmdline. booting OK.

Could you provide more details about failure in nomodeset mode?

[Anthony Wong (anthonywong)]

A “safe graphics” mode has just been added to 19.04. It is present in the latest daily test image, which can be found at http://cdimage.ubuntu.com/daily-live/current/. 19.04 will be release on Apr 18.
