whoah, your email client is not a friend of line breaks, is it? :) > I am unable to figure out how to share an "uinput device" across virtual X > sessions. I can't see anything obviously wrong here. Unless you're using a really really old evdev version that runs an EVIOCGRAB on the device this should work. > > The sample code for "Virtual Touch Device" can be found in > https://drive.google.com/file/d/0B2lQr8WlvKmzUVNDN0dETUVodEU/view?usp=sharing I really recommend using libevdev to create uinput devices. makes things a lot easier to read. https://www.freedesktop.org/software/libevdev/doc/latest/group__uinput.html Cheers, Peter > > Thanks, > Prakash > > On 23 February 2017 at 08:29, Peter Hutterer <peter.hutte...@who-t.net> > wrote: > > > On Wed, Feb 22, 2017 at 12:25:07PM +0530, Prakash P wrote: > > > > > > Hi, > > > > > > I want to create an virtual test environment for my web application.
