Can someone with serial console access try NixOS kernel on Librem 5?

Hardware Librem 5
34

I’m afraid I’m not using my Librem 5 at all. It is just too slow and too limited to spark joy.

Sound in calls and the camera don’t work with NixOS. Although I expect both can work with some effort.

All other software available for aarch64 works (currently running gnome).

I do play with the Librem 5 now and then. I’ve just reinstalled on a single partition to see if is feasible, to eliminate the trouble of planning disk layout during installation. And it is:

[ookhoi@librem5:~]$ sudo fdisk -l /dev/mmcblk0
Disk /dev/mmcblk0: 29.12 GiB, 31268536320 bytes, 61071360 sectors
Units: sectors of 1 * 512 = 512 bytes
Sector size (logical/physical): 512 bytes / 512 bytes
I/O size (minimum/optimal): 512 bytes / 512 bytes
Disklabel type: gpt
Disk identifier: FCC00EA4-5943-4056-878B-17D8D388CAFA

Device         Start      End  Sectors  Size Type
/dev/mmcblk0p1  4096 61071326 61067231 29.1G Linux filesystem

[ookhoi@librem5:~]$ df -h / /boot/
Filesystem      Size  Used Avail Use% Mounted on
/dev/mmcblk0p1   29G   17G   11G  63% /
/dev/mmcblk0p1   29G   17G   11G  63% /boot

What I dislike most about the Librem 5 is that there is no upstream support. I’m stuck with the ancient kernel versions that Purism provides - currently 6.6.74 - with no prospect that the Librem 5 will ever be a truly libre Linux device.

I am thankful for all Purism has done for Linux on mobile.

How is your experience with PureOS on Librem 5?
