Subject: [PATCH libinput] evdev: fix inverted mouse normalization
|
||
|
|
|
||
|
|
Regression introduced in 9f8edc5fd880e0a9c482b36e6b4120ccc056ee0b where it
|
||
|
|
changed from delta / (dpi/default) to delta * dpi/default, causing the inverse
|
||
|
|
effect of what the dpi setting is supposed to achieve.
|
||
|
