What is the maximum number of lens the heads up display will shown in Ubuntu 12.10? I would like to know, and I am sure other would as well. I don't want to install more than allowable or usable.

Lenses are not used by the HUD, they are filters for the Unity Dash. – speter Dec 2 '12 at 13:58

I haven't heard of an existing limitation. I have seen screenshots of Dash screens with every available lens displayed, so I think you can install at least 10-15 lenses without running into problems.

This would be a good answer if you can backup your 10-15 figure with a fact - link to the source code where 10-15 is stated? – fossfreedom Dec 2 '12 at 14:41
True, but my answer is based on experience, not on knowldge of the code. – speter Dec 2 '12 at 15:59
I have installed lenses on a test machine about a month ago, and came to an odd finding. Now realize this was on the last beta release of 12.10. Once I got up to around 11 or 12 lenses as I installed one, one of the earlier ones I had installed would no longer be visible in the heads up display. So I am thinking either there is a limit or a setting. – user106986 Dec 2 '12 at 16:56
Or maybe some just get out of the visible range and can only be summoned by a shortcut? – speter Dec 2 '12 at 17:38
That is one possibility. I cannot find any information on that option. It would be nice if we could size the HUD to accommodate our preferences and lens usage. – user106986 Dec 2 '12 at 19:02

Theres actually a way to resize the unity dash, once you open, you can click the maximize buttom in top-left of it. If you dont like it maximized, you can always Ctrl+Tab to navigate thru them once the dash is open.
