"Can't read from hidraw, is the program running as root?" #181

Open GCAT01 opened 1 day ago

GCAT01 commented 1 day ago

Just installed linux-surface (you guys rock!) and I have been having trouble with the touchscreen/gestures. Through my various searches for troubleshooting, I came across the command iptsd-find-hidraw and I received the following:

[warning] Can't read from /dev/hidraw#, is the program running as root?
[info] No devices found

where "#" is a digit from 0-4.

I have yet to see this message listed anywhere as an output of any iptsd command so I am asking for some guidance.

Well, are you running it as root? Only root can interact with hidraw devices.
