4.15.0-24-generic, ThinkPad T430. Uses Intel HD iGPU graphics (nvidia dGPU disabled in BIOS).
Recently started having this issue with a slow boot, where the boot process hangs on a black screen for an indefinite period of time before finally displaying the normal login splash screen.
Process looks like:
- OEM Bios select screen
- blank, black screen (< 1 sec)
- Blue Xubuntu title splash (< 2 sec)
- Some grub printout (< 1 sec)
- A black screen that has a blinking white cursor block (< 1 sec)
- A blank, black screen with nothing on it (approx. 10 sec)
- Finally, login splash screen
No idea why it started doing this. Was working fine before. The only thing I've noticed, which may be a red herring or irrelevant, is that there have been a bunch of updates to the
mesa package lately when I
apt update and upgrade.
Most other posts I've seen related to a hanging black screen on boot are either ancient (12.04) or unrelated (stuck on grub, or the flashing-cursor screen instead of blank). Though it seems like most of those posts are related to editing the grub file (
For reference, my grub file reads:
GRUB_DEFAULT=0 GRUB_HIDDEN_TIMEOUT=0 GRUB_HIDDEN_TIMEOUT_QUIET=true GRUB_TIMEOUT=10 GRUB_DISTRIBUTOR=`lsb_release -i -s 2> /dev/null || echo Debian` GRUB_CMDLINE_LINUX_DEFAULT="quiet splash nouveau.runpm=0" GRUB_CMDLINE_LINUX=""
and the relevant output of

Unfortunately was not able to figure out the source of the issue. I tried nearly every permutation of grub settings, but that did not end up changing the hanging boot issue. My guess it is probably related to the
4.15.0-24-generic. Decided to reinstall Xubuntu 16.04 for this issue and a few more I've had with 18.04.
If anyone else is experiencing this hanging boot issue and solved the issue, please provide your solution for others (and possibly me if I decide to roll the dice again when Xubuntu 18.04.1 drops).
