       I’m going to go over a lot of the yak shaving I  did to set up the [[Lenovo M900 Tiny]].

     

       2

       3
       -
       This is going to sit right next to my [[Unifi Dream Machine]] router plugged in via Ethernet, which is right at the front of our apartment. There’s a portable monitor there, but it only has USB-C as video input. 

     

       4
       -
       

     

       5
       -
       This m900 has two DisplayPort connections and…a VGA connector. Maybe I can use my old projector as a screen? But no, I don’t have a female VGA cable, just male-to-male. Maybe this USB B (projector side) to USB-A will …just work if I plug it in?

     

       6
       -
       

     

       7
       -
       What kind of adapters do I have? Should I plug it into the TV temporarily???

     

       8
       -
       

     

       9
       -
       I had to take it into my back office (which only has wireless and this only has Ethernet) to plug it into the DisplayPort of my monitor. 

     

       10
       -
       

     

       11
       -
       I’ll unplug the monitor from the USB-C KVM Switch (because I’m only going to have modern machines that all have USB-C, right), and also get my desktop keyboard and mouse out of the switch and directly into the m900.

     

       12
       -
       

     

       13
       -
       I’m booting into Windows and it wants the Internet.

     

       14
       -
       

     

       15
       -
       OK, can I plug it into my MacBook Air and bridge into its wifi? My USB-C adapter dongle doesn’t have Ethernet. Does the one I gave to Rachael have Ethernet? It does!

     

       16
       -
       

     

       17
       -
       Is this even going to work? (searches for Mac Internet Sharing) Yes this is built into System Preferences -> Sharing. Do I know which interface this Ethernet adapter is? No, just enable them all.

     

       18
       -
       

     

       19
       -
       OK, it works!

     

       20
       -
       

     

       21
       -
       Now we have various times of ignoring all the Microsoft upsells and ask for information (this is Windows 10 Pro) and we get to a desktop. I have a Microsoft Account with some paid family plan stuff so I’m in.

     

       22
       -
       

     

       23
       -
       Updates, turn on Remote Desktop. Let’s see if this works? It does not, because of the Ethernet to Mac sharing wifi, the m900 is double NAT-d.

     

       24
       -
       

     

       25
       -
       Read some stuff about dual booting Ubuntu and Windows. Actually I search for it - in Microsoft Edge so I guess this is Bing - and it gives me sort of a ChatGPT interface with the answer. The links go to the most horrendous ad-filled pages but I kind of squint at the info. 

     

       26
       -
       

     

       27
       -
       I don’t really need Windows on here but let’s keep it around just in case. Shrink the C partition to 200GB, leaving 750GB for Ubuntu. The wording in this dialog is bad. “Shrink by” is asking you how much smaller. “Shrink to” would make more sense to me. 

     

       28
       -
       

     

       29
       -
       Download a server image and unetboot. Apparently Ubuntu recommends Rufus for this.

     

       30
       -
       

     

       31
       -
       Burn image to USB stick. I ordered this at the same time as the m900, knowing at least I would need a spare or so for this.

       One annoying thing right away is that the specs are different than what I ordered: 8GB RAM instead of 16GB (less), a 1TB drive instead of 500GB (more), and a slightly different CPU.

       ## Different Specs

     

       8
       +
       

     

       9
       +
       As noted [[2024-01-19_1306]], I received a different spec. Booting into windows and the overview showed me:

     

       10
       +
       

     

       11
       +
       ```

     

       12
       +
       Processor Intel(R) Core(TM) i5-6600T CPU @ 2.70GHz   2.71 GHz

     

       13
       +
       Installed RAM 8.00 GB (7.89 GB usable)

     

       14
       +
       ```

     

       15
       +
       

     

       16
       +
       Looking at the hard drive, it's 1TB.

     

       17
       +
       

     

       18
       +
       And my [Amazon order](https://www.amazon.ca/gp/product/B07ZPBDFGD/ref=ppx_od_dt_b_asin_title_s00?ie=UTF8&th=1) was supposed to be "Quad-Core i5-6500T, 16 GB DDR4, 480 GB SSD Intel Graphics, USB WiFi, Windows 10 pro 64 Bit"

     

       19
       +
       

     

       20
       +
       There also isn't any Wifi in the one I received.

     

       21
       +
       

     

       22
       +
       So, half the RAM, faster processor, twice the hard drive space, and no Wifi. I will probably just keep it, but feels like less RAM will be a challenge.

     

       23
       +
       

     

       24
       +
       ## Initial Unboxing

     

       25
       +
       

     

       26

       31
       +
       

     

       32
       +
       I had to take it into my back office (which only has wireless and this only has Ethernet) to plug it into the DisplayPort of my monitor. 

     

       33
       +
       

     

       34
       +
       I’ll unplug the monitor from the USB-C KVM Switch (because I’m only going to have modern machines that all have USB-C, right), and also get my desktop keyboard and mouse out of the switch and directly into the m900.

       OK, it works!

       ## Installing Ubuntu

     

       59
       +
       

     

       60
       +
       Researched various Lenovo things. `F12` is what you need to press in order to get into firmware and boot settings.

     

       61
       +
       

     

       62
       +
       Selected the USB key to boot from.

     

       63
       +
       

     

       64
       +
       Chose the [Ubuntu Server install](https://canonical-subiquity.readthedocs-hosted.com/en/latest/tutorial/screen-by-screen.html)

     

       65
       +
       

     

       66
       +
       Got to the storage section and the 750GB unformatted part of the drive wasn't visible. The [server storage guide](https://canonical-subiquity.readthedocs-hosted.com/en/latest/explanation/configure-storage.html#configure-storage) says:

     

       67
       +
       

     

       68
       +
       > The installer cannot edit partition tables. You can use existing partitions or reformat a drive entirely, but you cannot, for example, remove a large partition and replace it with two smaller ones.

     

       69
       +
       

     

       70
       +
       Went into the help menu and got into the terminal. Thought about it for a bit and looked at some partition formatting links (all of the defaults show a graphical editor), and decided to boot back into Windows.

     

       71
       +
       

     

       72
       +
       In Windows, formatted the the 750GB, then booted back into the installer.

     

       73
       +
       

     

       74
       +
       Used LVM, made `/` root of 30GB, swap of 20GB, remaining as `/home`

     

       75
       +
       

     

       76
       +
       Install was very quick. Named the server `tinyhome`.

     

       77
       +
       

     

       78
       +
       There's an option to add SSH keys from Github. Entered my username and it fetched a couple of keys.

     

       79
       +
       

     

       80
       +
       Rebooted to Grub menu, then on to commandline login. Can I get it to automatically boot into Ubuntu? It's going to be running headless.

     

       81
       +
       

     

       82
       +
       Read some [background on Grub settings](https://ubuntuforums.org/showthread.php?t=1195275). Tried to get it to boot into Ubuntu / last saved OS by default with a short 3 second time out.

     

       83
       +
       

     

       84
       +
       `sudoedit /etc/default/grub`

     

       85
       +
       

     

       86
       +
       `sudo update-grub`

     

       87
       +
       

     

       88
       +
       None of the things I applied and rebooted did anything other than bring me back to a menu with a 30s countdown that defaults to Ubuntu. OK fine!

     

       89
       +
       

     

       90
       +
       Moved to living room and rebooted. Had previously set the router to give this device the same IP address.

     

       91
       +
       

     

       92
       +
       Logged in with my ssh keys. Success!

     

       93
       +
       

     

       94
       +
       Oh oh. Revving, **screaming** fan noises that ramp up and down. Searched a bunch of things, and now...fan noises have gone away.

     

       95
       +
       

     

       96
       +
       Need to do more research, because having it screaming in the corner of the living room is not going to be OK.[^livingroom]

       To load everything that is needed, add this to /etc/modules:

       If you have some drivers built into your kernel, the list above will

     

       137
       +
       contain too many modules. Skip the appropriate ones!

       141

       142
       +
       Ran `pwmconfig`:

     

       143
       +
       

     

       144
       +
       ```

     

       145
       +
       /usr/sbin/pwmconfig: There are no pwm-capable sensor modules installed

     

       146

       ```

     

       147
       +
       

     

       148

       Did some research. Found [this thread](https://github.com/vmatare/thinkfan/discussions/215) with this comment from January 2023:

       > On an M900 I had to force the kernel to load the nct6683 driver as stated here: [https://bugs.launchpad.net/ubuntu/+source/lm-sensors/+bug/1858369](https://bugs.launchpad.net/ubuntu/+source/lm-sensors/+bug/1858369)

       152

       So apparently I can force a kernel module to load, but getting various permission errors.

       echo "options nct6683 force=1" >> /etc/modprobe.d/sensors.conf

       OK, you really do need to be `root`, so `sudo su` it is.

       The fans are screaming this morning, so trying this again. This is applied after reboot, running `pwmconfig` now gives some output:

     

       163
       +
       

     

       164
       +
       ```

     

       165
       +
       Found the following PWM controls:

     

       166
       +
       

     

       167
       +
          hwmon2/pwm2           current value: 243

     

       168
       +
       

     

       169

       170
       +
       

     

       171
       +
       Giving the fans some time to reach full speed...

     

       172
       +
       

     

       173
       +
       Found the following fan sensors:

     

       174
       +
       

     

       175
       +
          hwmon2/fan2_input     current speed: 7017 RPM

     

       176
       +
       ```

     

       177
       +
       

     

       178
       +
       The fans really are too loud, and 7017 RPM is a lot.

       Looking at [[Coolify]] again, it needs Debian as the "admin", and also it is still quite a new system. I would probably try the hosted Coolify at $5/month as the admin controller.

       OK, sure, let's go straight to advanced mode and setup some local addresses.

       Sure, let's setup Cloudflare and see what happens. Make a new API token with access to `bmann.ca`, setup `home.bmann.ca` as the domain, and `my.home.bmann.ca` would be where the panel ends up.

       OK, none of this is going to work until I port forward. Let's go look at Unifi Router.

       OK, I turned off that Unifi local DNS of `home.bmann.ca`, and undid all of the private DNS settings. Accessing Cloudron from the public IP address, and it is being forwarded to the server.
