2020-04-12 02:45:52 Tim Richardson description I think this is a problem with the splash boot loader. I have installed 20.04 to this laptop. Clean install, not an upgrade. When booting from the install, the greeter screen is never reached if external monitors are connected at startup. I get the spinning ubuntu logo, and nothing more. I can not change to virtual terminals. In recovery mood, I can log in. I am used to having such problems with Nvidia graphics is involved, but this is not the case on this laptop. It has been happily running 18.04. External displays are recognised if they are connected after login. Also, when I edit /etc/default/grub so that it reads GRUB_CMDLINE_LINUX_DEFAULT="" (that is, splash disabled) it works fine with two external monitors attached.

There are no direct logic changes in the fix, only a significant increase to an existing timeout for "plymouth --ping". That increase will not incur any slowdown because the command returns as soon as an answer is known, even if plymouthd is not running. The timeout exists only to account for a busy plymouthd. [Original Report] I think this is a problem with the splash boot loader. This problem is not reproduced if using nosplash. I have installed 20.04 to this laptop. Thinkpad T480, i7, intel graphics. Clean install of 20.04 beta, not an upgrade. When booting from the install, the greeter screen is never reached if external monitors are connected at startup. I get the spinning ubuntu logo, and nothing more. I can not change to virtual terminals. The fsck step does not commence. In recovery mood, I can log in. With no external monitors attached, it works. I am used to having such problems with Nvidia graphics is involved, but this is not the case on this laptop. It has been happily running 18.04. External displays are recognised if they are connected after login. Also, when I edit /etc/default/grub so that it reads GRUB_CMDLINE_LINUX_DEFAULT="" (that is, splash disabled) it works fine with two external monitors attached.
