Lenovo Legion Go

jasonkhanlar · 2023-11-04 05:53:14

Hi! I purchased and began using a Lenovo Legion Go November 3rd, 2023 and immediately proceeded with installing Archlinux on the device. I encountered a glitchy screen booting the A liveusb, but I got around the inconvenience using a usb c hub with hdmi connection to external monitor and usb keyboard and then later remote ssh connections using another computer. Overall I successfully installed and am running Archlinux on the handheld computer, and it's almost mostly useable, at least with a bunch of cables sticking out of it using like a laptop/desktop computer and not a portable handheld. I noted some of the installation process here https://old.reddit.com/r/LegionGo/comme … se_on_the/ and for this post, I'll share some informations similarly as I shared in https://bbs.archlinux.org/viewtopic.php?pid=2120784

Issues (in no particular order):

Left and right input controllers do not function sufficiently as expected/desired. See pictures of controllers at https://google.com/search?tbm=isch&q=le … tbs=imgo:1
- I've made some progress to potentially get all the controls fully functional, and even though `xev` doesn't detect everything, `usbhid-dump` detects everything! See https://old.reddit.com/r/LegionGo/comme … hows_that/
[solved] Apparently SDDM login screen only rotates the screen visually, and the touchscreen cursor movement input is not rotated. I mentioned what I did in https://old.reddit.com/r/LegionGo/comme … se_on_the/ Is there a way to also rotate the touchscreen sensor too? As shown in https://wiki.archlinux.org/title/SDDM#L … ed_display I put `xrandr --output eDP --rotate left` in /usr/share/sddm/scripts/Xsetup
- Solved, see bullet point mentioning "Create /etc/X11/xorg.conf.d/rotate.conf" in https://old.reddit.com/r/LegionGo/comme … se_on_the/
When the screen blanks out from inactivity (whether at gdm/sddm/etc login screen or logged in to gnome/plasma/etc), tapping or moving finger across the touchscreen to try to wake up the device does not wake it up. If I do not have a wired/wireless keyboard connected to the device, then how do I wake it up to turn the screen back on? Of course, given what I researched and wrote here (https://old.reddit.com/r/LegionGo/comme … e/k7wtrlz/), I can use the "Open virtual keyboard" shortcut and hold the Legion L button and press the B button, and that turns the screen back on, but it would be nice to swipe the screen to turn it on too!

Notes:

The FPS mode off/on switch at the bottom of the right detachable controller toggles the device to switch between identifying as:
- fps mode switch off: ID 17ef:6182 Lenovo Legion Controller for Windows
- fps mode switch on: ID 17ef:6185 Lenovo Legion-Controller 1-9E
and the data above may not consistently reflect this device in the same state.

[work in progress]

Hi, have you tried setting libinput properties manually? It's possible that the device is not being tagged correctly. See https://wayland.freedesktop.org/libinpu … t-via-udev
