I recently needed to dust off my wifi skills, and to keep a low profile, I use my GPD Pocket laptop. My install of Kali was old, so I decided to see if I could load Kali 2020.3 on it. After much searching and futzing about, it turns out almost everything works right out of the box. You need a couple files, some settings, and a trick with the installer. I also found the archlinux wiki page on GPD really useful, oddly enough.- Run the text-mode installer.
- When you're asked to load the brcm files from a USB drive, say "no."
- It will successfully find all the APs around you, so select yours.
- But, it *won't* be able to negotiate WPA2 without the missing files.
- Tell it you're using an open wifi network.
- Let this fail. (If you'd told it WPA2 it it would be in a loop of failing and re-asking you the PSK.)
- Now, select the option to continue without a network connection.
- Install and reboot.
- Log in to your new system.
- (If your screen is rotated, click to the Kali logo, pick Settings, then Display, and set Rotation to "Right.")
- Put a copy of this brcmfmac4356-pcie.gpd-win-pocket.txt file on a USB drive. (Kali can read FAT.)
- Write a copy into /lib/firmware/brcm/brcmfmac4356-pcie.gpd-win-pocket.txt on Kali.
- Reboot. (I know, I know, I could use modprobe.)
- Log in to your system.
- Click the Kali icon, choose Settings, then Advanced Network Configuration.
- Double-click your SSID.
- Go to the Wi-Fi Security tab.
- Update your settings to reflect that you use WPA, and provide a password.
- Save
You'll also need to tweak the touchscreen configuration, which doesn't know it is rotated, yet.
- Edit /usr/share/X11/ xorg.conf.d/40-libinput.conf
- Inside the "InputClass" stanza for "libinput touchscreen" add this:
- Option "CalibrationMatrix" "0 1 0 -1 0 1 0 0 1"
- Restart
