17.10 to 18.04 upgrade freezes during boot

18.04

I just took a working Gateway P4 desktop computer and upgraded it from 16.04LTS all the way to 17.10 without any problem. As soon as I tried to install 18.04LTS, I had trouble booting.

I've reinstalled in many different ways, with no improvement in the boot problem. The Ubuntu logo appears and the dots flash a few times, then the mouse pointer freezes and the system is totally unresponsive. If I boot with the "quiet splash" removed from the kernel line in grub, I can see that it just stops shortly after starting the first user account 120.

Here is a clue... If I replace "quiet splash" with nomodeset, it boots fully, but it's in 640x480 mode only.

Here's the i915 video information...

  *-display UNCLAIMED
       description: VGA compatible controller
       product: 82945G/GZ Integrated Graphics Controller
       vendor: Intel Corporation
       physical id: 2
       bus info: pci@0000:00:02.0

I suspect that I need to add a special i915 video controller kernel parameter to grub to make the video work properly. Any ideas on what parameter that might be... or any other ideas?

Update #1: I just discovered that if I boot into "Recovery Mode", and then choose "Resume normal boot", it boots fully, to a 1024x768 4:3 (should be 16:9) desktop.

Update #2: Upgrading from 17.10 to 18.04, booting fails. Reinstalling 18.04, booting fails. Disk partition delete and clean 18.04, booting fails. Installing 18.04 "proposed" software, booting still fails. Ubuntu Live DVD works fine.

Update #4: I'm currently running with i915.modeset=0 in my grub kernel line, it's booting, and I'm getting 1024x768 (4:3).

Update #5: Updating to kernel 4.16.9 doesn't fix the problem.

Update #6: A portion of @karel's answer provided a good enough workaround. Switching from gdm3 display manager to lightdm display manager works. I could then also remove i915.modeset=0 from my grub kernel line.

sudo apt-get update
sudo apt-get install lightdm
# if lightdm wasn't already installed, it'll ask which dm you want
# if lightdm was already installed, then you need to:
sudo dpkg-reconfigure lightdm
# and choose lightdm over gdm3
reboot

Update #7:

Turns out that the problem isn't a gdm3 vs lightdm problem. It's a gdm3/wayland problem with older Intel GPU's. To fix...

In terminal...

cd /etc/gdm3 # change directory
sudo pico custom.conf # edit this file

Find and change:

#WaylandEnable=false

To this:

WaylandEnable=false

Save the file.

sudo dpkg-reconfigure gdm3 # select gdm3 DM

Select gdm3 and OK.

reboot # reboot the computer

Setting kernel options for the i915

How can I fix broken i915 drivers for Intel GPUs?

Solution 1:

Try logging in to your default desktop environment from the tty virtual console. The virtual console can be accessed by pressing the keyboard combination Ctrl+Alt+F3 after the computer gets stuck when booting it. Login to the virtual console with your username and password and run the following command.

sudo systemctl start graphical.target

If that doesn't work, switch the login display manager from gdm3 to lightdm. LightDM is a more lightweight login display manager than gdm3.

sudo apt install lightdm   
sudo dpkg-reconfigure lightdm 
sudo reboot

sudo dpkg-reconfigure lightdm will open up a new window allowing you to select lightdm as the default login display manager. Use the arrow keys to select lightdm, press the Tab key to put the focus on <OK> and press Enter. Then reboot by running sudo reboot

Try booting from Xorg instead of Wayland. Edit /etc/gdm3/custom.conf with sudo nano /etc/gdm3/custom.conf, uncomment #WaylandEnable=false so it is WaylandEnable=false and run sudo dpkg-reconfigure gdm3 # select gdm3

If that doesn't work either see if you can at least switch to text mode (for troubleshooting purposes) with no GUI stuff like the X server running.

sudo systemctl start multi-user.target
