Hard to swipe left/right on MX4

[Krzysztof Tataradziński]

Hello,

I came back to UT from Android (last time I used UT with OTA-9). In present (OTA-11) version, there is really hard for me to show left launcher or swipe from right to show open apps. I must admit that before there was no problem for me. What changed?

Please see attached video.

I've installed UT again, but old version (Ubuntu 15.04 (r26)), and magic! left/right edges works much better. Please see attachment. Maybe when UT changed to have smaller GUI (icons, scopes, etc. - is that called grid?), also changed that edges are thinner?

[Krzysztof Tataradziński (ktatar156)]

Updated to latest OTA-11 and there is still problem with that. I think that is because of 'grid' units on screen.
I don't know how it works, but suppose that left/right edge was set to react in 1/10 grid. And suppose that in r26 there was 10 grids, so edges react in 1/100 of the screen. While in newer version UT there are more grids (lets suppose 20), so edges react in 1/200 part of the screen. Maybe there is problem? Because of creating more grids, 'edges reacting' area should be increased (in that example to 1/5 to get the same area 1/100)?

@Pat do you know where I can find code responsible for edges? Is it in some config file that can be edited?

great question, there are settings available

gsettings list-keys com.canonical.Unity8
will show all the options to control

$ gsettings get com.canonical.Unity8 edge-drag-width
uint32 2

$ gsettings set com.canonical.Unity8 edge-drag-width 3

cool, I didn't know there were settings for it, thanks Pat! :)

If tweaking the settings doesn't work out, you can try having a look at the code.
I'm not familiar with the code that handles the swipe gestures, but I had a quick look and I think the gesture area on the left is defined here

while the are on the right side is defined here
http://bazaar.launchpad.net/~unity-team/unity8/trunk/view/2440/qml/Stages/PhoneStage.qml#L716

Note: that's PhoneStage, but it seems there is also a TabletStage and DesktopStage implementing the same area. Not sure how Unity8 switches from what to the other

have fun!

Status changed to 'Confirmed' because the bug affects multiple users.

I've tested command "gsettings set com.canonical.Unity8 edge-drag-width x" with '3' and '4' number. First one seems to be working great! 4 maybe is too big value. Could you set that for MX4 in next OTA?
