Can't set touchscreen
Closed this issue · 6 comments
I just installed rot8 through the rot8-git AUR package. Upon trying rot8 --touchscreen "ELAN9008:00 04F3:2C82", it hangs and never finishes it doesn't rotate the screen (I misunderstood). Is there something I'm missing?
I am experiencing the same thing, will let you know if I find out anything / get it to work
@ngharrison I got it to work by getting the name for my touchscreen device with: xinput list
then running: rot8 --touchscreen "<name of my touchscreen>" worked as expected
@xnghu Yes, that's what I did as well. I'm not 100% sure that I've picked the right one though since none of them say anything about a screen. My output from xinput list:

With the new update giving a useful error message and looking into the code, I found that my accelerometer can't be found. Somehow my entire /sys/bus/iio/ directory disappeared. I know it existed before because I had a different auto-rotate package working a week ago. Not sure how to get it back, but this issue is resolved.
I've fixed my accelerometer problem -- the /sys/bus/iio/ directory exists again and I can monitor rotation changes using monitor-sensor in iio-sensor-proxy. But auto-rotate still doesn't work. Am I doing something wrong with the name? I checked using udevadm info --export-db and "ELAN9008:00 04F3:2C82" has ID_INPUT_TOUCHSCREEN=1. I also tested it with all other possible names listed in xinput list for fun but no change.
The command I'm using: rot8 --toucscreen "ELAN9008:00 04F3:2C82"
The name I was using for the touchscreen was correct. In the end, it wasn't working because the values weren't normalized appropriately for my machine. Mine needed rot8 --normalization-factor 10 --touchscreen "ELAN9008:00 04F3:2C82". This is resolved.
