Xubuntu 18.04, 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 (/etc/default/grub
line GRUB_CMDLINE_LINUX_DEFAULT
).
Any ideas?
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 lscpi -k
lspci -k
00:02.0 VGA compatible controller: Intel Corporation 3rd Gen Core processor Graphics Controller (rev 09)
Subsystem: Lenovo 3rd Gen Core processor Graphics Controller
Kernel driver in use: i915
Kernel modules: i915
Things I've tried:
- change
GRUB_CMDLINE_LINUX_DEFAULT
to"quiet splash
instead of"quiet splash nouveau.runpm=0"
GRUB_TIMEOUT=0
instead of10
- updating
mesa
,xserver-xorg-video-intel
packages, both already installed and current - updating kernel (was already at latest,
4.15.0-24-generic
)
Update:
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).
quiet
to see what's happening during the 10 seconds.quiet
did not change anything to the hanging black screen, which comes after the grub splash (which is <1.5 sec).
