Successful 22.04 install -- Can't login after restart
Chambana opened this issue · comments
Using a Macbook Air M1. Installed using the prebuilt image and install script. System was stable after a full day of use. Booted the system this morning and I can't get a login prompt.
Thank you for the report.
After the initial install, were you able to successfully reboot the device?
Yes I was. I had a successful reboot iirc.
Are there are logs or troubleshooting I can do to help diagnose the issue?
As far as changes made the machine after install, I did at least the following:
- installed firefox via apt
- installed chromium-browser via apt
- installed ROS2 Humble via apt
- etc
Can you switch to a tty with ctrl-alt-fn-f3? If yes, can you show us the output of apt list --installed | grep asahi? Another think that might work is holding ESC after the u-boot automatic boot timeout or ctrl-alt-del to get a grub boot menu and try if you can boot an older kernel (if there is one).
Yes, I'll log my results here:
-
fn-ctrl-option-f3successfully dropped me to a tty login prompt -
I've attached the results of
apt list --installed | grep asahi. -
-
tapping
escright after the autoboot timeout did drop me a grub menu w/2 available kernels -- 6.1.0-1asahi and 5.19.5-10-asahi. -
-
From a cold boot, I've confirmed that the 5.19.5-10-asahi kernel boots as expected into a desktop login prompt and I can successfully login and drop to a desktop environment. This is the login screen that I land on before entering my password
-
From a cold boot, I've confirmed that the 6.1.0-1-asahi kernel drops me to a deadend login screen with no login prompt
Is the 6.1.0-1-asahi supported on a macbook air m1?
I used the Step 7 of this grub tutorial to set my default boot kernel to 5.19.5-10-asahi and the system boots consistently.
ok, so it looks like our kernel is broken on your hardware and we need to roll out an update to fix it.
Here's how you could help us with that if you have some spare time:
- I have already built a newer kernel here https://launchpad.net/~tobhe/+archive/ubuntu/asahi-kernel-build/+sourcepub/14980499/+listing-archive-extra
- You can download it by clicking linux-image-6.3.0-7-asahi_6.3.0-7.8_arm64.deb and linux-modules-6.3.0-7-asahi_6.3.0-7.8_arm64.deb
- Next
apt install ./linux-image-6.3.0-7-asahi_6.3.0-7.8_arm64.deb ./linux-modules-6.3.0-7-asahi_6.3.0-7.8_arm64.deb, that should automatically trigger a grub update adding a new boot entry. - See if that new kernel works. If it does we can release it
Happy to.
I followed the steps above and manually installed the 6.3.0-7.8 kernel. I manually selected this new kernel from the grub menu (extra step because i forced grub earlier to stick with 5.19). The new kernel successfully dropped me to a desktop GUI as intended and this behavior survived several reboots. So, anecdotally, this kernel update totally fixed my issue. Thanks!
(it also resolved a screen brightness issue I was having on 5.19, but that would've been a separate ticket. Unfortunately, it didn't resolve the disgustingly dirty state of my computer screen and I'll have to manually handle that with some windex. I swear it doesn't look that dirty in real life).
FWIW, I also see a 30% increase in aggregate CPU performance when moving from the 5.19 kernel above to the new 6.3 kernel.

Now that's an interesting data point. I am not sure what causes this but it might be some kind of cpu power management improvement. More reasons to push out the update I guess.
Results from running the same benchmark on the same hardware on native MacOS. For some reason the Ubuntu 6.3 kernel is only showing 4 cores (not 8) and a much lower clock rate for the CPU.

I think there might be a little more gain once all packages are up-to-date, not just the kernel. Not sure how passmark determines the number of cores but try running nproc or htop and see what that says.
Hey ! So I followed the same steps from one you previous answer, in this thread I also have everything working but the GPU acceleration ! as it's linked to kernel 6.1
