Overlay scrollbars do not permit WPA/WPA2 Enterprise connections with CA certs

[Eric Appleman]

If you connect to a WPA2-Enterprise network and do not choose a CA cert, you will be presented with a modal dialog in which neither option can be selected with the mouse or keyboard. The mouse focus is still on the window underneath.

Bug disappears when launching gnome-control-center with LIBOVERLAY_SCROLLBAR=0

[Marius B. Kotsbak (mariusko)]

Is this a regression from Quantal? I haven't seen it. Could you please add a screenshot of the problem?

[Eric Appleman (erappleman)]

Not a regression as far as I know. I could try a 12.10 VM later.

But here's that screenshot.

[Marius B. Kotsbak (mariusko)]

Okay, I have never had any problems choosing ignore in that dialog, but I haven't tested newer releases than Quantal.

[Marius B. Kotsbak (mariusko)]

Do you see a pattern for the connections that you experience this problem with?

Any wireless enterprise connection where you can provide a CA
certificate file but do not.

[Marius B. Kotsbak (mariusko)]

I wonder which scrollbar that is involved in this. Is there any scrolling in the window behind the dialog? Also please compare with the behavior in a Quantal live CD.

[Eric Appleman (erappleman)]

Cannot replicate in Quantal live CD. Haven't tried a full install.

So, I guess it's a regression until proven otherwise.

Btw, to trigger this bug, you don't even need an actual network. You can try connecting to a nonexistant hidden network (preferably PEAP) as long as the criteria are met and no cert is chosen.

[Marius B. Kotsbak (mariusko)]

Are you running Unity? Does this happen in the network menu at top right corner (nm-applet), or only in control center?

It can happen from the network applet so long as the network actually
exists and enterprise menu comes up to configure the network.

The bug is present with both Unity and GNOME-Shell.

[Launchpad Janitor (janitor)]

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

[Jonathan Harker (jonathanharker)]

Affects me in 13.04 using default Ubuntu Unity. Problem goes away when I apt-get purge overlay-scrollbar which is an abomination anyway. I am amazed that anyone can get anything done with it.
