However withing the BIOS I found that settings for the touch panel could be changed. When switching from Goodix GT7385 device (which works in windows) to Goodix touch device when running the command again I get a new output  > > Line 50 d  > > Unsure if this is progress?  Yes this is definitely progress for some reason changing the BIOS option seems to have turned on the touchscreen. The output now looking like this: [henry@archlinux ~]$ sudo i2cdetect -y -r 9 0 1 2 3 4 5 6 7 8 9 a b c d e f 00: -- -- -- -- -- -- -- -- 10: -- -- -- -- -- -- -- -- -- -- -- -- -- -- -- -- 20: -- -- -- -- -- -- -- -- -- -- -- -- -- -- -- -- 30: -- -- -- -- -- -- -- -- -- -- -- -- -- -- -- -- 40: -- -- -- -- -- -- -- -- -- -- -- -- -- -- -- -- 50: -- -- -- -- -- -- -- -- -- -- -- -- -- 5d -- -- 60: -- -- -- -- -- -- -- -- -- -- -- -- -- -- -- -- 70: -- -- -- -- -- -- -- -- Indicates that the touchscreen is at the expected 0x5d address, which matches with the "Goodix GT7385 Device" option in the BIOS. I wonder what happens if you change the BIOS option back to "Goodix GT7385 Device" ? Does "sudo i2cdetect -y -r 9" still show the 5d entry then and/or does the touchscreen maybe start to work. > I'm wondering if the bios has 2 different options. One for windows driver and one for generic Linux? (If that's a thing)  No that is not it the "Goodix Touch Device" option you chose is for a different Goodix touchscreen at address 0x14. The touchscreen now showing up at address 0x5d matches with the original "Goodix GT7385 Device" selection. Regards, Hans
