Description Lili Huang 2020-07-08 01:49:12 UTC 
1. Proposed title of this feature request

Disable left edge gesture.

2. Who is the customer behind the request?

3. What is the nature and description of the request?

According to the following link, left edge slide brings activities overview and applications.
----
https://wiki.gnome.org/Design/OS/Gestures
Edge drag: Left edge brings up overview with the app picker open

http://opengrok.brq.redhat.com/source/xref/RHEL-8/gnome-devel-docs/3.28.0/1.el8/gnome-devel-docs-3.28.0/hig/C/pointer-and-touch-input.page
191 <p>Left edge opens the Activities Overview with the application view visible.</p></td>
----

Customer requests a feature to disable this gestures.

4. Why does the customer need this? (List the business requirements here)

The RHEL OS with a touch screen attached is used as a panel to do the embedded operations.
RHEL gnome is just used to connect to a remote PC. Almost the operations are performed on that remote desktop, rather than RHEL desktop.

In this situation, if left edge brings overview and applications, there is a high risk for customer which may lead an erroneous operation.

Now the environment is in test stage and it's difficult for customer to judge if RHEL is a proper OS to be used as a panel until RFE is fixed.

5. How would the customer like to achieve this? (List the functional requirements here)

Add a feature to have left edge gesture can be disabled.

6. For each functional requirement listed, specify how Red Hat and the customer can test to confirm the requirement is successfully implemented.

Confirmed that left edge slide does not open overview and applications.

7. Is there already an existing RFE upstream or in Red Hat Bugzilla?

No.

8. Does the customer have any specific timeline dependencies and which release would they like to target (i.e. RHEL5, RHEL6)?

Customer expects this feature can be used by Oct. 2020.
And customer wants this feature can be used on RHEL 8.1.

9. Is the sales team involved in this request and do they have any additional input?

No.

10. List any affected packages or components.

Gnome-shell. 
Kernel (?).

11. Would the customer be able to assist in testing this functionality if implemented?

Customer is willing to assist in testing.
But if the time is much slower than customer's expectation (Oct. 2020), it would be difficult for customer to test.
Comment 2 Michael Catanzaro 2020-07-08 03:52:18 UTC 
Hi Lili,  I think the following command should do what the customer wants:

$ gsettings set org.gnome.desktop.interface enable-hot-corners false

That was implemented in bug #1704355. Please let us know if that suffices.
Comment 4 Lili Huang 2020-07-08 05:14:21 UTC 
Sorry, I deleted the customer's info in comment #1.

I tried enable-hot-corners key just now (with dconf update and logout/login), 
but left edge still brings overviews and applications.

I loaded a screen snapshot which shows what left edge opens.

left edge opens overviews and applications
Comment 6 Michael Catanzaro 2020-07-08 12:51:50 UTC 
Hm, it works for me in 8.2. This was supposed to work in 8.1 as well; I'll install 8.1 to see what's going on there.
Comment 7 Michael Catanzaro 2020-07-08 18:18:46 UTC 
OK, I see I misunderstood: you don't want to disable the hot corner, you want to disable the left edge slide gesture. I should have read your comment better, sorry.
Comment 8 Lili Huang 2020-07-13 08:02:42 UTC 
Yes, customer wants to disable the left edge slide.
By the way, can you please make the first comment to be published, because I want customer to monitor this RFE himself too.
Comment 48 Michael Boisvert 2021-06-09 20:47:21 UTC 
Using gnome-shell-extension-gesture-inhibitor-3.32.1-19.el8.noarch.rpm, I was able to disable the left side "drag reveals tray" gesture by simply setting: 

$ gsettings set org.gnome.shell.extensions.gesture-inhibitor show-app-grid false
Comment 52 Michael Boisvert 2021-06-09 20:50:48 UTC 
I should point out this works as expected with both mouse clicks and touchscreen.
