Touchpad on asus chromebook doesn't work (RW_LEGACY firmware)

System Details

  • Device: TELTIC (n50)
  • OS: Debian 13
  • Firmware Type: RW_LEGACY
  • Firmware Version: I installed it earlier today so should be the latest?
  • Internal storage type: eMMC

Summary of the Issue

I used the mrchromebox script to try to install the RW_LEGACY firmware because I cannot arrange a SuzyQ cable in my country to unlock WP on my asus CX1405CTA (intel n50), after that I used the CRAP script to repartition and recovered around 113 gb out of 128 on the eMMC.

Installing debian 13 was a success but once I tried setting up a GUI, the touchpad didn’t work on either i3 or sway WMs, the libinput debug logs said that it sensed “touchpad jumps” and ignored them and I think the OS actually detected the touchpad.

I also wanted to know whether there are hardware support and performance disparities between full uefi and RW_legacy.

this is an issue with the Pixart touchpad used on your device, search the forums for Pixart and you’ll find the solution. It’s simply an OS calibration/configuration issue, not a firmware one

yeah actually, it got resolved.

I even got the audio working.

could you tell me whether in general there are any performance or hardware compatibility benefits to full uefi installation over rw_legacy?

this is what resolved my issue

if you’re not running ChromeOS, UEFI Full ROM is preferred as it is more updated, cleaner boot, with working NVRAM. RW_LEGACY is only for dual booting with ChromeOS

but am I gonna get throttled hardware acceleration or audio mismatch, webcam glitches, stuff like that on rw_legacy and not on full uefi?

no idea, wouldn’t expect so
