If you switch to imps, the kernel doesn't switch the touchpad to touchpad mode so the firmware emulates a PS/2 compatible mouse. You can verify this by running evemu-record, you should see BTN_LEFT, etc. as well as REL_X/Y. It's more of a firmware bug in that the device is only ever tested with windows and if it works there, they ship it. If we don't have the same behaviour as the windows driver we trigger bugs that windows doesn't have to care about. as you could see from the libinput vs synaptics behaviour - different pointer acceleration suddenly shows up a bug that's effectively unfixable without emulating that behaviour (which can break other devices, yay).</pre> </div> <hr> You are receiving this mail because: <ul> <li>You are the assignee for the bug.</li> </ul> </body> </html>
