Over year ago I was struggling with the annoying issue at linuxes. I experienced it at many distributions and it turned out to be related to Linux - kernel, and the graphics drivers.

[drm:drm_atomic_helper_commit_cleanup_done [drm_kms_helper]] *ERROR* [CRTC:26:pipe A] flip_done timed out

drm_kms_helper_issue

This issue was causing that the machine was booting endlessly - many minues over the expected seconds.

The solution is to edit the file /etc/default/grub and modify the entry from: GRUB_CMDLINE_LINUX_DEFAULT="quiet splash" to: GRUB_CMDLINE_LINUX_DEFAULT="video=SVIDEO-1:d"

Removing options: quiet splash turns on boot logs instead of the splashscreen, and now I can know what is going on with boot of my linux box.

Additionally I modified from: GRUB_TIMEOUT_STYLE=hidden to GRUB_TIMEOUT_STYLE=menu The last modification is enabling grub menu to be always visible at boot time.

Next I needed to run command:

sudo update-grub

and reboot the computer.
