## Framework 16 Fixes
|
|
|
|
### Wake from Sleep
|
|
|
|
The keyboard/mouse can be pressed through the lid while in a backpack. Disable them to
|
|
prevent wake from sleep.
|
|
|
|
`/etc/udev/rules.d/69-suspend.rules`
|
|
|
|
```conf
|
|
ACTION=="add", SUBSYSTEM=="acpi", DRIVERS=="button", ATTRS{hid}=="PNP0C0D", ATTR{power/wakeup}="disabled"
|
|
ACTION=="add", SUBSYSTEM=="serio", DRIVERS=="atkbd", ATTR{power/wakeup}="disabled"
|
|
ACTION=="add", SUBSYSTEM=="i2c", DRIVERS=="i2c_hid_acpi", ATTRS{name}=="PIXA3854:00", ATTR{power/wakeup}="disabled"
|
|
|
|
# https://askubuntu.com/questions/848698/wake-up-from-suspend-using-usb-device
|
|
ACTION=="add", SUBSYSTEM=="usb", ATTRS{idVendor}=="32ac", ATTRS{idProduct}=="0012", RUN+="/bin/sh -c 'echo disabled > /sys$env{DEVPATH}/power/wakeup'"
|
|
```
|
|
|
|
Reload
|
|
|
|
```bash
|
|
sudo udevadm control --reload-rules && sudo udevadm trigger
|
|
```
|
|
|
|
### Wrong keys pressed in the browser
|
|
|
|
Sometimes keys will stop working when using search bars or do strange things like move the page around. This seems to be caused by some "alt" keypress combination. Pressing "alt" twice fixes it.
|
|
|
|
### Wifi Powersave
|
|
|
|
**NOTE: THIS DOESN'T WORK. IT CAUSES WIFI DISCONNECT AND RECONNECT ISSUES.**

|
|
|
|
```bash
|
|
vim /etc/NetworkManager/conf.d/wifi-powersave-off.conf
|
|
```
|
|
|
|
```conf
|
|
[connection]
|
|
# Values are 0 (use default), 1 (ignore/don't touch), 2 (disable) or 3 (enable).
|
|
wifi.powersave = 2
|
|
```
|
|
|
|
```bash
|
|
systemctl restart NetworkManager
|
|
```
|
|
|
|
## Podman
|
|
|
|
Since you'll be using podman for most container-based services, you'll want to set the
|
|
the podman auth file to somewhere persistent, otherwise it'll get deleted every time you
|
|
reboot.
|
|
|
|
Add this to your `.bashrc`:
|
|
|
|
```bash
|
|
# Podman auth file
|
|
export REGISTRY_AUTH_FILE=$HOME/.podman-auth.json
|
|
```
|
|
|
|
Source that and then run `podman login` to create the file.
|
|
|
|
### Autostarting services with quadlets
|
|
|
|
If you want to run something as your user at boot (like a systemd process, think ollama) you can
|
|
create a user quadlets like so:
|
|
|
|
```bash
|
|
# Generate the .container file
|
|
podman run --rm ghcr.io/containers/podlet --install --description "Local AI" \
|
|
podman run \
|
|
-d \
|
|
-v ollama:/root/.ollama \
|
|
-p 11434:11434 \
|
|
--name ollama \
|
|
--restart always \
|
|
docker.io/ollama/ollama > ~/.config/containers/systemd/ollama.container
|
|
|
|
# Verify the service (Note the filename:service, this is required! You will get "Failed to prepare filename" without it)
|
|
systemd-analyze verify ~/.config/containers/systemd/ollama.container:ollama.service
|
|
|
|
# Start the service
|
|
systemctl --user daemon-reload
|
|
systemctl --user start ollama
|
|
```
|
|
|
|
## Network
|
|
|
|
### VLAN Setup with nmcli
|
|
|
|
```bash
|
|
# VLAN 2
|
|
nmcli conn
|
|
export NMCLI_DEVICE=enp195s0f4u1u3
|
|
nmcli connection add type VLAN con-name $NMCLI_DEVICE.2 dev $NMCLI_DEVICE id 2
|
|
```
|
|
|
|
## ZRAM
|
|
|
|
Increasing zram size
|
|
|
|
```bash
|
|
# Show existing configuration
|
|
zramctl
|
|
#
|
|
swapoff /dev/zram0
|
|
# Reset swap
|
|
zramctl -r /dev/zram0
|
|
|
|
# Set a new size
|
|
zramctl --size 4G /dev/zram0
|
|
```
|
