clicking twice on expo in unity launcher takes you to a different workspace

[Rocko]

If I click once on the expo icon, I see all four workspaces with my default current workspace in the top left. If I press escape, the screen returns to the current workspace.

However, if I click again on expo instead of pressing escape, the workspace changes away from the default to a blank workspace, whereas I expect it to return to my current workspace.

this needs to be fixed in compiz-plugins. the fix is:

Open ccsm go to expo>>'Appearance' tab and change 'X space' slider to "64"

Thanks for the bug report. This particular bug has already been reported and is a duplicate of bug 837545, so is being marked as such. Any further discussion regarding the bug should occur in the other report. Feel free to report any other bugs you may find.

Changing that setting to 64 doesn't fix the problem for me - what is it supposed to do? My screen resolution is 1920x1080 in case that is relevant.

I don't think this is a duplicate of 837545. That bug is about layout and this one is about being taken to a different workspace.

What fixes the problem for me is reducing the curve strength (I have the expo appearance set to curve instead of tile or none). A higher curve strength increases the chance that I'll be taken back to the workspace below the default one.

I don't think this is a duplicate either. But LaunchPad is giving me errors when I try to clear the duplicate status.

Also, I can't reproduce this bug at all. Is it still a problem? If not then it won't hurt to leave as is...

[Rocko (rockorequin)]

I still experience this bug occasionally, even with the expo set to tile (ie no curve). I suspect it is much more likely to happen if I have an external monitor plugged in - I'm no seeing it now with no external monitor.
