indicator applets disapear when using twinview then disabeling a monitor

[Uli Tillich]

Binary package hint: unity

Ubuntu 11.04 Natty -all updates installed-
Nvidia Drivers: 260.19.29-0ubuntu1

When using a dual screen setup with nvidia twinview and both monitors side by side, the top panel spans both monitors. The Unity Dash Launcher is at the left edge, the indicator applets at the right edge.

If any monitor is disabled via the nvidia-settings tool (by setting the resolution to "off"), the Dash Launcher remains at the left edge of whichever screen is on. The indicator applets however are not displayed on the new narrower panel.

Re-enabling the second monitor resets everything to the way it was before disabling it.

So is the problem just that Unity doesn't resize itself correctly when you turn off a monitor? Could you post screenshots to make the problem a little bit more clear? Thank you.

[Uli Tillich (utillich)]

Yes, I think the top panel not resizing properly to the reduced horizontal resolution is exactly whats happening.
After one monitor is turned off, only the portion of the panel which was on the left monitor before is shown.
Sorry if it was not explained clearly before.

Unfortunately I can't supply screenshots atm; I cant run the proprietary drivers since the x-server was updated, thus cant run unity. I might have an older ISO (with the old x-server) which I could use to reinstall, or try and downgrade, over the weekend to make the screenshots if they are really needed.

Perhaps someone could test this with other graphic cards as well, it might not be limited to nvidia.

Ok, I just retested this, and the problem is definitely that unity does not scale to the new resolution.
The panel does not adapt when the resolution is lowered, or increased.

I found that this problem has already been triaged, so ill mark this as a duplicate.

it's not only that it does not rescale after you unplug/replug the 2nd monitor.. The top panel should just fit in the first screen in the first place, just like the original gnome panels don't extend to both screens.. or there should be the option "extend to left/right monitor".

[Dimitris Sevastakis (dsevastakis)]

so it may be related to but #684539 but i don't think fixing the 684539 will make the panel detect the size of the primary screen and then make it fit to it..

@ Dimitris:
As far as I know, the panel extending over both monitors is a conscious decision of the Unity design Team.
Check bug #683084 for some discussion about it.
Though note that that bug is about global menu, so if you want to comment on the size of the panel search for, or file, the corresponding bug
