Apps locked to launcher only launch once per session on dual monitor system.

[Rachel Greenham]

[Impact]

Users having the Launcher only on a monitor that is not the left-most monitor can only open the application once. This can lead to much frustration and a restart of the system in order to open the application again using the Launcher.

[Test Case]

* Have a multi-monitor setup.
* Using System Settings, go to Displays.
* Under General options, click the drop down for Launcher placement and select the right-most monitor.
* Click an icon to open a application. Close that application and click the icon again.
* The application should open again with this fix.

[Regression Potential]

None identified.

Original Description:

In Trusty:

On a dual monitor system with the launcher on the right hand screen, an application that has been "locked to launcher", (including those there by default) can only be clicked on once per session to actually launch the application. After that it's unresponsive to clicks, although right-click actions work.

Seems to affect all apps, including "Files".

To repeat, for any application not already on the launcher bar:

Launch the application using the dash.

Right-click on its launcher icon and select "Lock to Launcher"

Quit the application.

Click on its launcher icon. It should launch again.

Quit it again.

Click on its launcher icon again. It won't work this time. It looks like dragging would work, but its operation as a launcher will not.

NB: I haven't installed any hacks eg: click-to-minimise. Seen this on two systems upgraded from saucy to trusty. (One with AMD graphics, one with Intel, so I doubt that's relevant either.)

[Rachel Greenham (rachel-strangenoises)]

In case anyone ever looks at this, I thought I'd describe how to repeat the issue more simply, though it was implied in the above.

As default, there is a launcher icon for "Files" at the top of the launcher, under the Ubuntu logo.

Click on it once. Nautilus launches showing the home folder.

Close that window.

Click on the "Files" icon again.

... nothing.

[Rachel Greenham (rachel-strangenoises)]

This seems to only affect upgrades from Saucy - even if the Saucy install itself was unmodified from default (as in the case on this machine, installed only briefly to upgrade to Trusty with).

Clearing all likely gnome/unity config has also cleared this problem.

[Rachel Greenham (rachel-strangenoises)]

spoke too soon. issue spontaneously re-arose on the machine where previously it was fixed by clearing gnome/unity config.

[Rachel Greenham (rachel-strangenoises)]

OK, I think I found out what this is about. Can reliably repeat it now.

It's about having multiple monitors. I have three. This problem occurs if I set the launcher placement to be anything other than "All Displays" or the leftmost display.

(Confirmed by swapping displays around in the display prefs; whichever one is spacially positioned leftmost is fine; if the launcher is on (and only on) any other display, this issue occurs.)

But I want my launcher in the middle! :-) Situation here is that the middle display is a 27" 2560x1440, and the two on either side are 24" 1920x1080. Having just one launcher on that big middle screen, and pushing new windows from there to the outer displays at need, works well for me, and of course ought to be a supported choice, as the UI lets me do it. ;-)

Of course what I really really really want is the launcher on auto-hide along the bottom of every display, but that's not going to happen. :-(

Hey, is anyone actually seeing this? I haven't even had a bot come by and ask for more information...

[Colin Law (colin-law)]

I am seeing this too after upgrading to 14.04, for example click on Files, close the window, and clicking on Files then does nothing. Right click > Open New Window still works.
Seems to be a rather serious bug, I wonder why more are not seeing it. Perhaps it is an upgrade issue.

[Rachel Greenham (rachel-strangenoises)]

Can you confirm my finding of my last comment, that is:

This happens when the launcher is only on one display of a multi-display desktop, and when that isn't the left-most display?

[Colin Law (colin-law)]

Yes, well spotted, for me it only happens when the launcher is on the right hand display of a pair. That explains why it is not seen by more users.

Also it is not to do with having upgraded from 13.10 as I also see it with a separate install of 14.04 on a different partition on the same machine which was installed as an early beta and has been updated from there.

[Colin Law (colin-law)]

Interestingly if I suspend and resume then the launchers work again (but only once).

[Colin Law (colin-law)]

@Rachel what graphics chipset/card are you running? I know that someone with nvidia graphics is unable to replicate the problem. You can run
lspci
in a terminal to see, it should have a line something like the one below, which shows that I have Intel graphics

00:02.0 VGA compatible controller: Intel Corporation 3rd Gen Core processor Graphics Controller (rev 09)

[Rachel Greenham (rachel-strangenoises)]

This was observed with both a RadeonHD 7750 and Intel HD4600; both using stock opensource drivers/mesa et al. Two separate machines, btw. I'm afraid I sold my nVidia card that I used to use, but the fact those can't drive more than 2 monitors at once means I wouldn't have chosen the configuration that revealed it in the first place (ie: wanting launcher only on middle of three monitors). I suppose it's possible that nVidia's TwinView may be having an effect, if it means the logic of how it handles multi-monitor is reflected up at the levels at which Launcher is coded. (In that case Nouveau might show it.) But remember from earlier observations: this only occurs if the launcher is placed on one screen, not all of them, and that the screen it's placed on is *not* the one on the left.

Is clearly a bug :-) Can't possibly be a design feature a: that the launcher behaves differently on different monitors of a multi-monitor setup, and b: that it works correctly exactly once per session. *Never* working would at least imply malign design choice! ;-)

Also, it didn't happen in Saucy. I'd had that Launcher-in-the-middle config for some time before the upgrade to Trusty beta.

[C de-Avillez (hggdh2)]

easily reproducible. In my case the monitors are vertical, and the lower one is the laptop's. When setting the launcher to appear on the built-in, I can reproduce the bug.

Bypass: set launcher to appear on all monitors.

[C de-Avillez (hggdh2)]

addition -- forgot to add graphics:

00:02.0 VGA compatible controller: Intel Corporation 4th Gen Core Processor Integrated Graphics Controller (rev 06)

[Christopher Townsend (townsend)]

I can reproduce as well. I'll look at getting this fixed for the next 14.04 Unity SRU.

[John Felso (felso)]

 The bug occurs on clean installs of trusty as well.

[Tim Wernicke (pprspam)]

Same here. Fresh install of 14.04 64-bit, dual monitor setup. When I set the launcher to only display on one monitor, I can only click each icon in the launcher once. Trying to interact with those icons a second time receives no response.

If I then set launcher to display on both monitors, I immediately regain access to all icons in the launcher on both monitors.

[Tim Wernicke (pprspam)]

Forgot to mention: I'm running an Nvidia GT 640 card with the proprietary nvidia driver.

[MaXiMuS (dupmail)]

Same bug affects me, running 14.04 with a tripple monitor setup, RadeonHD 5830 and default driver that is installed (not running the proprietary AMD driver yet but will give it a try)

[Alex (axfelix)]

Updated to Trusty today, using Sandybridge, two monitors, same behaviour as everyone else.

[md_5 (md-5)]

GTX 770 with proprietry 319, same issue.

[xlefay (xander-u)]

Same here, Intel IvyBridge Mobile

[Robert Tari (robert-tari)]

Same bug here, fresh install of 14.04 amd64, GeForce 8200, proprietary 304.
By the way, you can launch the application by holding SHIFT and left clicking.

[Launchpad Janitor (janitor)]

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

[Alex (axfelix)]

Any chance this will be available upstream anytime soon? It's actually a huge pain for a package that doesn't tend to be updated in between Ubuntu point releases...

[Christopher Townsend (townsend)]

Hi Alex,

A version of Unity with this fix should be trusty-proposed right now.

Thanks!

[Rachel Greenham (rachel-strangenoises)]

But I'm used to having the launcher on every display now!

(ducks and runs!)

I'll try it tomorrow. :-)

[Rachel Greenham (rachel-strangenoises)]

Couldn't wait for tomorrow. I was just so excited! ;-)

I can confirm it does appear to be working as expected now, yes. Confirmed also it stays fixed after logging out and logging into a fresh session after making the config change. So my preferred config of the launcher on the middle display only, apps can be launched more than once. :-)

(NB: Applied all pending trusty-proposed updates rather than trying to cherry pick those that might relate to this. All seems well.)

[Bob McGimpsey (bob-mcgimpsey)]

Thanks Alex,

That is exactly the setup... Have laptop and monitor for extended desktop, with monitor as primary and on RIGHT-SIDE. The launcher is on the primary monitor(right-side), and encounters the problem. Sorry, I did not think to experiment with putting the Launcher on the laptop... would have lived with that... I backed out of the 14.04 and went back to 13.10... was concerned that if such a bug was discovered right out-of-the-box, what other surprises might be awaiting... decided to allow others to discover..

Perhaps I may update to 14.04 again and observe your suggested work-around.

Thanks again...

I'm sorry, after completely restarting my system everything seems to be fine. Sorry for the scare.

[Svetoslav (svetoslav80)]

I'm aware this bug have been fixed but I experience a similar issue on PC with a single monitor. Folders locked to launcher only launch once (including trash bin). I'm still able to launch these by holding SHIFT. Not sure if these bugs are related but I thought I'd better mention it here.
