multitasking view doesn't work when nVidia is on [$15]

[Eka Cahya Pratama]

my laptop using both intel and nvidia graphic. So i install nvidia driver from X server from X.org and bumblebee to switch it. When PRIME profile switched to nVidia and then log off, the multitasking view doesn't work. it just open an interface but there is no preview and cant switch workspaces. When PRIME profile swiched back to intel and then log off, the multitasking view work just fine.

Asus U33 JC - NVIDIA Corporation GT218M [GeForce 310M] -- same issue.

[Kyle (agronick)]

I noticed that the output when running Gala from the command line is slightly different when running from Nvidia as opposed to Intel. Has this been posted before?

WIth so many people dependant on having this fixed to use their relatively expensive graphics hardware I don't see anyone working on this.

Does anyone have an idea on where someone should go about looking in the code to fix this issue or how they should go about debugging it? Do you guys just use Nemiver to debug?

[Kyle (agronick)]

I tried hacking with the code. Couldn't find anything. I don't even know how you go about debugging something like this. I read what it said in the HACKING file but it said nothing about how to step through the code. Using Nemiver wasn't too helpful.

Heres my output when starting it using Nvidia:

[Vitaly Maltsev (maltsev-vitaly)]

Is there any workaround for this issue?

[Kyle (agronick)]

I had an interesting breakthrough when working with the code. If I remove && !window.on_all_workspaces on line 197 in WorkspaceClone.vala I can see the windows in the workspace switcher. Apparently the window is on all workspaces if there is only one workspace. The bug has to do with there only being 1 workspace apparently. This is a guess. The only thing I know for sure is removing that line of code fixes part of the problem.

[Daniel (danielpc80)]

Confirmed on Samsung RC-730 with Nvidia GT 540M

[Kyle (agronick)]

Perhaps the bug is being caused by all the windows having on_all_workspaces set to true. This causes it to disregard all the windows. When running Intel it looks the same as Nvidia if no windows are open.

Remving !window.on_all_workspaces on line 197 in WorkspaceClone.vala causes all the windows to show up in the worspaces switcher but I still can't add more workspaces.

[Kyle (agronick)]

Could someone point to the filter for on_all_workspaces where it checks if its ok to add another desktop. Removing that line might allow it to work normally.

Guys, is there any chance that this issue will be fixed? This problem totally breaks elementary OS experience I'm using it for. Numerous users are affected.

[Kyle (agronick)]

If you guys would give me some direction I could probably help fix this. The issue could be because of a library. I'm pretty sure that whatever sets on_all_workspaces is setting the wrong value on nVidia cards.

[Henrique Cézar (juniorg-4)]

As of 2015-09-05 this bug still occur on my HP Pavillion 14-v066br laptop with fully updated Elementary OS

[Kyle (agronick)]

What version is this fixed in? I'm running 0.2.0~r474+pkg32+build1~ubuntu0.3.1 and it seems to be the same as it was before.

It could just be me though because I did a lot of hacking trying to fix this issue. I did a make uninstall on the source which definitely removed my changes but it seems to be back to the original state of the problem.

[Cody Garver (codygarver)]

Gala itself was not the problem, it was a bug in the Utopic Xorg stack which was resolved by switching to the Vivid stack.

[Kyle (agronick)]

Sounds good. But what do I need to do to get this update? I'm switching myself from elementary-stable to elementary-daily right now. Sounds like that won't be much use. Should I switch everything from trusty to vivid?

[Kyle (agronick)]

My idea of replacing vivid in the sources was a terrible one. I ended
up reinstalling the entire os. At least the problem is fixed.

Works great after a fresh installation of eOS 0.3.1

[Vitaly Maltsev (maltsev-vitaly)]

Guys, updating to vivid didn't work for me. I still can't access multitasking view, but have all latest components in place:

[Vitaly Maltsev (maltsev-vitaly)]

Can this be resolved without full reinstallation of the elementary?

[Nam Lah (namlah)]

Same here.
Asus X555, Nvidia 840M v.A2.

Workspaces work fine either in dual or single display when using integrated video (Intel); attempting to switch workspaces when Nvidia profile is on, will not work. Also, there are intermittent display freezes; will have to kill the X server, log into tty1/2 and get back to GUI afterwards by doing Ctrl Shift F7.

[Abolfazl (tireng69)]

multitasking view doesn't work when nVidia is on GT630

[Nikhil Handa (nikhil-handa19)]

I confirm that it doesn't work on GT630m as well.
