On touch screens, the apps icon in the dock does not open when touched

[Juan Pablo Lozano]

I have an Bangho AERO 1104 with touch screen, when I try to open the application drawer from the applications icon in the dock, it does not open.

1)- Ubuntu 17.10 Artful Aardvark 64 bit
2)- gnome-shell-extension-ubuntu-dock_0.7
3)- What should happen is that touching the applications icon in the dock, opens the application drawer.
4)- Instead, what has happened is that absolutely nothing happened

[Sebastien Bacher (seb128)]

Thank you for your bug report. What do you call "application drawer"? The dots grid that opens the softwares list screen?

[Juan Pablo Lozano (libredeb)]

@seb128 yes!, the dots grid that opens the softwares list screen. Thanks :)

[Launchpad Janitor (janitor)]

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

[PJSingh5000 (pjsingh5000)]

Are the following bugs related to this one?
Perhaps these bugs are different manifestations of the same underlying problem?..

If the dock receives two events, or responds twice to each event, then the Applications "dash" would seem to not appear when you touch the applications grid icon/button, because the applications dash would be quickly shown and unshown.

Here are examples of this "double" response , which seems to be limited to touch-screen interfaces:

Bug #1730281
"Application icons appear and suddenly disappear when Applications Button is activated via a touchscreen"

Bug #1705689
"When adding an app to favourites, two icons are created"

Bug # ???
I also noted that touching on an application in the dock opens two instances of the application.
I haven't seen if a bug report has been filed for this issue yet, but it would be additional evidence for my theory.

[PJSingh5000 (pjsingh5000)]

I've opened Bug #1730532 to capture the third issue (???) in comment #4:

"Tapping on an icon in the dock launches two instances of the application"

[PJSingh5000 (pjsingh5000)]

Using xinput, I captured touch events on the dock's Applications Grid Button. For comparison, I captured touch events on another portion of the screen, away from the dock.

The results are very interesting...

When I click on the Applications Grid Button on the dock, five (!!) Touch events are registered. These five events are enclosed by only one Touch Begin event and one corresponding Touch End event.

However, when I click on another portion of the screen, only one Touch events is registered, enclosed by one Touch Begin event and one corresponding Touch End event. This is how the dock should behave.

Please see the attached files.
I've inserted comments in the output to make it easy to count the events:

[PJSingh5000 (pjsingh5000)]

Touch events for Ubuntu Dock, showing 5 events for a single touch.

[PJSingh5000 (pjsingh5000)]

Touch events for the screen, showing 1 event for a single touch, as expected.

[François Glais (franglais125)]

Interesting that there are that many events. Can you tell how quickly they occur? Perhaps this can be fixed with a timeout.

[PJSingh5000 (pjsingh5000)]

It multiple events happen immediately.

HOWEVER...

I did the same test today, and I get different results...
- Sometimes, a single touch on the Dock only does generate a single TouchUpdate event.
- Sometimes, a single touch elsewhere on the Screen generates more than one TouchUpdate event.

You do have to be very precise with your touch actions to ensure only one TouchUpdate is produced. In general use, multiple TouchUpdate events are generated when you use your finger. I guess this is normal, and the application really just needs to look for a single TouchEnd event.

Both the screen and the Dock do generate a single TouchEnd event, and this is probably the important event that applications need to look out for.

Nevertheless, in the cases were I was able to cause a single TouchUpdate event on the Dock, I still got the same behavior:
- Touching the Applications Grid Button failed to display the applications overview.
- I momentarily saw the applications overview expand from the button, and then retract back into the button, as if I had tapped the Applications Grid Button twice, really fast.
- Touching an icon on the Dock (favorites) caused two instances of the application to be launched, as if I had tapped the application icon twice, really fast.

Does the issue have something to do with the way the Dock handles the TouchEnd events?

Caribou (onscreen keyboard) always pops up whenever you touch the screen; could this be influencing the behavior?

[Linus Seelinger (s-linus)]

I observe the same on a Dell Venue 7140. At least disabling Caribou using the Block Caribou extension does not solve the issue.

I would like to point out the severity of this issue, as this makes the dock virtually unusable for touchscreens and even can lock up the activities button at the top left.

[Linus Seelinger (s-linus)]

Now it gets weird. I installed gnome-session and it seems that here, both Caribou seems less intrusive and the "multiple touch events" issue does not occur even when activating the Ubuntu Dock extension.

[Linus Seelinger (s-linus)]

Sorry for the spamming, turns out in gnome session with Ubuntu Dock it's the same under X11, in Wayland it seems better/nearly perfect.

[Cubic PPA (cubic-wizard)]

Still experiencing this using gnome-session and Xorg.

$ uname -r
4.13.0-21-generic

$ gnome-shell --version
GNOME Shell 3.26.2

I think three problems are related:
1. Applications menu not shown when touching the Apps Icon (the application icons briefly flash onto the screen, and flash off)
2. Caribou always pops up
3. Touching a favorites icon in the dock opens two instances of the application

[PJSingh5000 (pjsingh5000)]

Note: if you touch "Activities" first, and then touch the Applications Grid Icon, then the dash showing all application icons appears without issue.

However, if you have the dock set set to "always show", and you happen to touch the Applications Grid Icon (before tapping the "Activities" label at the top left) then this issue appears.

[PJSingh5000 (pjsingh5000)]

Still experiencing this in Bionic 18.04...

* Touching the App-Grid icon in the dash-to-dock causes the app icons to appear, and quickly disappear. (It's as if you touched the App-Grid icon twice, very quickly).

* Touching a favorites icon in the dash-to-dock causes two instances of the application to open.
(It's as if you touched the favorite icon twice, very quickly).

I have such issues with Ubuntu Dock too on my laptop with a touchscreen. I can also confirm that gnome-shell --replace solves that problem. This problem appears only in X11. The problem doesn't appear on Wayland session but I use X11 due to few limitations on Wayland.
So please help to fix this issue.

I'm using Ubuntu 18.04 LTS. Gnome 3.28.2

[AlpineCarver (acarv)]

This bug affects me, running Ubuntu 18.04 on a Dell Venue 11 pro 7140.

I have a work-around that seems to be working reliably for the "Show Applications" dots grid button: tap-and-hold until the application icons appear, then slide your finger up into the dock bar, then release.

This only works for that one button; it does not solve the "Tapping on an icon in the dock launches two instances of the application" problem.

Can confirm this issue on an Asus T300 Chi and a Dell XPS 9360 on up to date Ubuntu 18.04 installations.

I think this is the upstream bug report:

[AlpineCarver (acarv)]

Cubic PPA: I just tried switching between Frequent and All applications view, and it's working OK for me.

The only change I've made that I can imagine affecting this is my use of onboard and gnome-shell-extension-onboard, but I think it's unlikely that that has made a difference.

When I first installed 18.04, I did get into a mode where most touch-screen events were being ignored, but that hasn't happened for a week now. A more detailed account of my experiences is here:

[Matt Ellis (95ellismle)]

The `gnome-shell --replace' workaround seems to fix this bug for me. However, this causes a new bug when I lock the laptop. After locking I cannot enter my password and it is as if someone is holding down the enter key and the words 'Authentication Error' flashes up.

I am using a Dell Inspiron 17 and Ubuntu 18.04.1 LTS. The Gnome version is GNOME Shell 3.28.2.

[Peter Bittner (peter-bittner)]

Is this bug being worked on by Canonical? The upstream project's bug report is more than 3 years old, how can that be explained? (Wasn't this component only included with 17.10?)

This bug breaks a critical part of the desktop interaction, rendering 2-in-1 devices not ready for mainstream consumption. Can this issue be escalated?

[Carlos Cesar Caballero Diaz (cccaballero)]

Same issue here in 18.04 using a Dell Inspiron 7373 (2-in-1) and xorg, I can confirm that "gnome-shell --replace" solves the dock issue, but seems that multi touch gestures stop working after that.

This specific issue is not present using Wayland.

[Tunghim Lam (tunghim)]

Same issue here in 18.04 using a Dell P2418HT touch monitor & Xorg.

[Juan Pablo Lozano (libredeb)]

This bug apply to Ubuntu 18.04.1 too. Please fix it!

[Johann Popper (lethedrinker999)]

Jeebus tap-dancing cripes, this bug breaks the cripesing apps button for cripes sake! It's a complete dealbreaker for the entire OS, as in you can't open applications on touchscreens! At all! Stop jerking users around. If you're not serious about desktop anymore (which is cool, we totally understand) just drop out of the desktop business altogether and stop pretending. Focus on servers and IoT and point desktop users to Mint. Jeebus!

This bug's level of absurdity defies criticism. I can't even be mad, so much as outraged to the point of non-stop laughter for hours. GNOME might as well have shipped nothing, then goes on playing dumb just to gaslight troll the FOSS community. I can't believe canonical and Ubuntu are willing to put their name on this steaming pile of Robotcop toxic waste. Sweet cripes on a pogo stick, OH the humanity! WOWLOL!

Let's get real here: GNOME shipped a touchscreen UI where you can't touchclick the APPS BUTTON. Knock, knock, anybody home!?!? Are there no tablets on the Isle of Man? 18.04 "LTS"!!! Well, it had better be LTS if we're all stuck on this slowmotion unnecessary crazy train to nowhere! You fellas should've just slapped Unity on there for another 5 year marathon. I'd have run with you; we all would've. Great Q almighty, I feel like a Hitler video....

[Peter Bittner (peter-bittner)]

Well, Johann, while there is _some_ truth in the words you say (and seemingly, you loved Unity as much as I did---did you also notice the massive memory footprint increase with 17.10, by the way?), I must say it needs some time to understand that yours is not SPAM or a troll's message, and we have to open our eyes to see some facts that prove the opposite of what you say. Partially, at least.

- The Ubuntu website was recently overhauled, with an obvious attempt to making "the sexiness of the Ubuntu desktop" appeal to users and vendors alike. With an undeniable focus on sporting Snap packages (hence, the IoT efforts have _at least_ a collateral effect on the Canonical's desktop efforts -- I don't think this is a coincidence). https://www.ubuntu.com/desktop

- Canonical has managed to have a tremendous success with bundling Ubuntu with vendor hardware, specifically with DELL. The DELL website, though there is room for improvement, offers lots and lots of models that come shipped with Ubuntu, some even _only_ with Ubuntu (no Windows available on them---typically, because Windows wouldn't run on that low-end hardware. :-} The price they pay is that, for what I've seen, DELL starts to offer (or had offered) some models also with RedHat Enterprise as an alternative desktop system. (That hurts bad! All the endless efforts, and then a somewhat competitor comes along and gets everything for free.) And, the DELL website is seriously broken. _They_ need to be kicked in their arses! https://dell.com/ubuntu :-{ ("marketing campaigns last for too short" *facepalm*) https://pilot.search.dell.com/ubuntu (the friggin' search is sooo brken!)

- And, yes, everybody seems to know that the GNOME code base is a total mess. But hey, Purism will fix it! *LOL* Seriously, the Purism phone efforts will give the GNU/Linux desktop maybe the final push that will lead to also Ubuntu increase market share on the desktop! (I love the future I see coming! ... even though some aspects of what Canonical needs to do are disturbing, e.g. favor vendors of non-free OSS services with their Snap apps in their marketing--because consumer market wants commercial support more badly than free software!)

TL;DR

The bug, in the GNOME extensions code base and predating(!) the release of 17.10 *facepalm*, must be fixed by "the community". https://github.com/micheleg/dash-to-dock/issues/128 (reported 2014! *LOL*)
Not sure who was so blind to pick that pile of poop to include it with 17.10 w/o at least skimming over the 215 (!) open issues... :-O

Jump in and help to fix it! Canonical is busy with IoT and updating websites! ;-)

[PJSingh5000 (pjsingh5000)]

This bug seems to only affect Xorg. Wayland is not affected (see https://bugs.launchpad.net/ubuntu/+source/gnome-shell-extension-ubuntu-dock/+bug/1725384/comments/18).

Since Xorg is not a priority, I suspect this bug is not getting attention.
Unfortunately, many of us have to use Xorg (if you have Nvidia hardware, for example).

Initially, I thought that perhaps Gnome is generating multiple touch events, causing the apps overview to open, and then close again (see https://bugs.launchpad.net/ubuntu/+source/gnome-shell-extension-ubuntu-dock/+bug/1725384/comments/10).

However, this could be an issue in Gnome Shell, Gnome Dash, Xorg, specific hardware, or something else entirely.

Let's see if we can narrow it down or find some kind of pattern, or clue, to what is going wrong.

Doing this may help provide the developers with enough information to spot the cause and fix this bug.

It would really useful for all of us to list the hard ware we have...

Reading through the bug report linked by Daniel van Vugt (vanvugt) in comment #24 (https://github.com/micheleg/dash-to-dock/issues/128), I noticed that Dash-to-Dock is only affected.

I had uninstalled the Ubuntu Dock...
$ sudo apt autoremove --purge gnome-shell-extension-ubuntu-dock

However, I was using the Dash-to-Dock extension, instead.
$ sudo apt install gnome-shell-extension-dashtodock

So, I disabled Dash-to-Dock.
Now the problem is gone.

Are all of you using either Dash-to-Dock or the Ubuntu-Dock?
If so, what happens when you disable or remove it?

[PJSingh5000 (pjsingh5000)]

The fact that the Dash is visible on the desktop ~immediately after~ a touch event seems to be contributing to the problem.

See this experiment I did...

I am affected by the same bug. Some extra information:
 - tapping definitely does something, as brief animation can be seen (icons flying away and back from button)
 - Sometimes tapping on icons switches on drag and drop mode (and stays like that), even though tap itself was short
 - I have tried cinnamon desktop (mint), and there was similar problem. Although mint menu would show, it was completely unresponsive. Unlike using mouse or touchpad.

Hey Marco, do you think you could have a look to this one after cosmic is out?

[arm-c (arickmcniel)]

Hello,

For what it is worth. I am affected by the same bug. It is frustrating. I agree with all of the information presented above regarding the bug and I have SOMETHING NEW TO ADD.

NEW: Not seen referenced anywhere is that a similar feature in "Workspaces to Dock" add on works exactly as expected when you enable the "favorites" feature. Touching (finger) ONCE on show installed applications reveals the installed applications. This information may be useful for those that are trouble shooting.

Confirmed The Following on my HP Spectre x360 Convertible 15-bl1XX.
>> Gnome Dash acts as expected without Dash to Dock, Dash to Bar, or Ubuntu Dock installed / active. (Clicking on show apps shows app with one click). I suspect that all share similar code to initiate show apps.
>> Initiating with long press then sliding finger off of show applications after expanded will leave drawer open.
>> Looks like sliding finger in from side of screen will show applications (default Gnome actions)... BUT it would be nice if swiping in again from side will return to pre-swipe conditions. As it stands now, you must press Escape Key, clicking show applications icon again and subsequently an open application, or clicking "Activities" in top left.
>> staring an application that permits multiple instances (ie terminal / files) will start two instances if started from click.

Presently, I am going to switch back to default gnome dash because of the touch issues... and use "pinch" to show open windows and swipe in to show applications. Hope they fix this sooner than later as I do like the "Dash to Dock/Bar" extensions.
