Sleep fix

The PCI SD card reader blocks ACPI sleep.

Solution: Disable wake for SD PCI syspath.

In /etc/udev/rules.d/20-pci-sd-card-nowake.rules:

SUBSYSTEM=="pci", KERNEL=="0000:00:02.3", ATTR{device}=="0x14ee", ATTR{power/wakeup}="disabled"

Real Sleep fix

from: https://gitlab.freedesktop.org/drm/amd/-/issues/3073

In /etc/udev/rules.d/20-i2c-amd-nowake.rules:

SUBSYSTEM=="i2c", KERNEL=="i2c-PNP0C50:00", ATTR{power/wakeup}="disabled"
SUBSYSTEM=="i2c", KERNEL=="i2c-GXTP7385:00", ATTR{power/wakeup}="disabled"

Block Paddles + gamepad mouse/keyboard mapping

This also disables the face buttons in keyboard/mouse mode.

Identify "keyboard"

$ lsusb
Bus 001 Device 003: ID 2f24:0135   Mouse for Windows

Solution: Block USB device.

SUBSYSTEM=="usb", ATTRS{idVendor}=="2f24", ATTRS{idProduct}=="0135", ATTR{authorized}="0"

Block or remap paddles

Run evtest as root and look for Mouse for Windows

$ sudo evtest
...
/dev/input/event4:   Mouse for Windows
...

Find out what it's currently mapped to by pressing the button while evtest runs, in my case it's 70046 which is print screen.

$ sudo evtest /dev/input/event4
...
Event: time 1698507272.813553, type 4 (EV_MSC), code 4 (MSC_SCAN), value 70046
...

Create a file at /etc/udev/hwdb.d/90-winmax2-paddles.hwdb

reserved maps the button to nothing:

# /etc/udev/hwdb.d/90-winmax2-paddles.hwdb

# WinMax2 Paddles + keyboard/mouse gamepad
evdev:input:b0003v2F24p0135*
# Left Paddle PRINT_SCREEN
  KEYBOARD_KEY_70046=reserved
# KEYBOARD_KEY_70046=leftctrl
# Right Paddle PAUSE
 KEYBOARD_KEY_70048=reserved
# KEYBOARD_KEY_70048=leftalt

Then update /etc/udev/hwdb.bin with systemd-hwdb

sudo systemd-hwdb update

Then reboot

systemctl reboot
