Older Acer Aspire laptop with i3 processor. Ubuntu loads fine when plugged in wall, but won't boot with only battery power. I see the Acer splash with bios information, but it turns off before ever seeing the purple Ubuntu boot up screen. Had no problems with Ubuntu 16.x. Laptop recently got new battery.
Any assistance appreciated.
This link worked for my HP laptop.
1) Modify the GRUB_CMDLINE_LINUX_DEFAULT kernel variable in /etc/default/grub:
GRUB_CMDLINE_LINUX_DEFAULT="quiet splash dis_ucode_ldr"
2) $ sudo update-grub
3) Reboot.
dis_ucode_ldr stands for "disable microcode loader"
That didn't fix things :/ I have noticed that the power state on shutdown, affects whether I get a freeze on boot. If the power states are not the same (AC / Battery), then I get a freeze on boot...
I fixed this issue using the following solution:
edit the sudo vim /etc/gdm3/custom.conf file by uncommenting the following line:
WaylandEnable=false
save and restart

Don't have enough points to leave a comment.
I have the same issue
Ubuntu 18.04
kernel v4.18.14
I have a Dell xps-15 i7 9570
which is known to have issues with Ubuntu, which required me to add the acpi override option to grub, as well as disabling nouveau.
Suspect it's an ACPI issue, or a graphics card - power managament issue...if that isn't the same thing...
I have the following in my /etc/default/grub file:
GRUB_CMDLINE_LINUX_DEFAULT="quite splash nouveau.modeset=0 i8042.nopnp irqpoll acpi_rev_override=1"
Boots fine if on AC power. freezes at splash screen if booting from battery power.
Any help would be great.
Going to try kernel v4.18.16 or possibly v4.19 (using Ukuu-gtk) and removing the acpi_rev_override=1 from grub. Just building up the courage first.
I had the same problem with my laptop and I solved the problem by updating the Linux kernel to the last version and setting the grub config as mentioned by Colin Anthony.
