Hi Luke,
Using today's rawhide Workstation Live iso image I was able to boot
and install to the NVMe drive. I added to the bootargs "arm64.nopauth
clk_ignore_unused pd_ignore_unused modprobe.blacklist=qcom_q6v5_pas"
post install I also had to add "arm64.nopauth clk_ignore_unused
pd_ignore_unused" and fix up grub after logging in t make it
permanent. there seems to be a bug in anaconda not carrying over boot
arguments to the installed system. With that I was able to boot and
log in. there is extra steps to get the touchscreen, 5g modem and
bluetooth working. additionally pd-mapper needs to be installed and
running for power management and a some other things to work
correctly, right now it looks like something has changed in 6.7 kernel
from 6.6 that is stopping pd-mapper from running.

I would definitely use it if it was possible. Even with just troubleshooting my black screen issue, I have noticed the battery dying very quickly. Hopefully that can at least be addressed one day. Kind of defeats the purpose of an Arm laptop, right?

> Dennis - thank you for the suggestions! I have not recently run into issues with USB itself. A few tests I did last week resulted in the root file system UUID not being found and another test led to the USB drive powering off (the RGB lights would flicker for a second and then turn off). Thankfully, that is not something I am seeing with my latest configuration settings. For whatever it is worth, I am currently using an external NVMe drive connected via USB-C. I have tried swapping out the internal drive that has Windows installed for another NVMe drive but the BIOS seems to cache the old boot entries and does not detect the new internal drive. It is unbootable.

However, I am having issues with Fedora and always end up with a black screen once the GPU gets loaded. I have tested with Fedora 39 (fully updated with the latest firmware and Linux 6.6) and Rawhide/40 (Linux 6.7.0-rc4 currently). Both GNOME (Workstation) and Xfce (Spin) desktop builds have been tested (I can never actually get that far to see them, though).

With these tweaks, I can boot to the GRUB menu and eventually see the Plymouth boot screen which shows the Fedora logo and then a loading spinner. When it switches to a graphical environment, the screen flashes and goes blank. I also seem to be unable to switch to a TTY console which could be due to the F keys not working properly.

I did all of the steps but the same thing happened: the screen ends up being black once the system is fully booted up. I have tested using USB and the internal drive. The USB, despite historically being unreliable, has been more reliable in my testing. I believe those issues with low power voltage for USB devices have been fixed.
