Bug Description

I'm loath to report this as a bug, since it is functioning as designed, but I can't really find a better place to submit my complaint. I'm running 9.04 Netbook Remix, and if I run a GUI application and do something requiring sudo privileges, I receive a password prompt that blocks access to any other windows on the screen. Fine and good, but because of a disability, my only means of keyboard input is the OnBoard on-screen keyboard. My only recourse for such basic tasks as installing updates and adding packages is to pull out the terminal, hope I can find the pertinent command, and sudo it so I can give my password via terminal. This rather negates the convenience of doing these things from the GUI.

Naturally, the expected behavior is that I be able to use OnBoard to enter my password into the prompt.

Any other user who uses an on-screen keyboard or other GUI-based application for keyboard input will be susceptible to this issue. I imagine there are a fair number.

Software center is slowly replacing all the features which are involved in installing and updating packages.
And It uses Policy-kit for the password prompts , which is not modal. Once all the features are completed , we should be able to avoid such accessibility issues

Thank you for bringing this bug to our attention. However, a paper cut should be a small usability issue, in the default Ubuntu install, that affects many people and is quick and easy to fix. So this bug can't be addressed as part of this project.

- The scope of this bug is much larger to be considered a papercut.
For further information about papercuts criteria, please read https://wiki.ubuntu.com/PaperCut.

Don't worry though, this bug has been marked as "Invalid" only in the papercuts project.

Since no one has mentioned it yet, gksu's grab can be turned off:
$ gconftool-2 --set /apps/gksu/disable-grab --type boolean true

or for a little gui run
$ gksu-properties
and select Grab mode: disable

You should then be able to type passwords with Onboard.

Certainly that's a workaround; I'm glad you mentioned it. I found out after
submitting this bug that prompts can be made not to grab via one of the
options in the Assistive Technologies section of Ubuntu Preferences (the
one below "Enable assistive technologies"). My only thought is that if
OnBoard is supposed to be a genuine keyboard substitute, it seems like an
overly broad solution--either gksu grabs focus from everything, including
OnBoard, or from nothing at. I wonder if it's possible to choose some
applications that are excluded from gksu's grab behavior? Seems like the
most satisfactory fix for the bug to implement that, and put OnBoard on
that list by default. I guess that makes this a feature request?

Well, we'd love to add this as a feature, but I'm not aware of anything that would allow us to generally exempt Onboard from pointer grabs. If this exists, I'd be interested to learn about it.

Back in GTK2 times Onboard used to have a toggle for "Password dialogs as normal windows", which basically toggled the disable-grab key. This fell by the wayside with the switch to GTK3 and gsettings. We could possibly bring it back, though going by the age of this bug and duplicates, I'm not sure if we should. Is this still an issue today?

for fixing the remianing issues in raring (where the plan is to get rid of gksu in favour of using pkexec everywhere), it would be good to know when exactly users get gksu prompts.
we need to fix the apps using it to instead use pkexec.
people seeing this issue on the nexus7, please tell us where/when exactly gksu pops up

i found a little work around for this... if you touch/hold your finger somewhere else on the screen you can usually (not always which i don't understand) then type with another touch input.

just in case i'm not being clear - touch screen with left hand then right hand type.

A while after boot and every now and than something crashes (I think it is cups) and then "System error occured" window appears, I think you call it whoopsie. When I click the "report" button, it asks for password using gksudo, and I can't enter anything.

Keyboard issues with ubuntu 13.04 on Nexus 7 16gb wifi
I have stumbled upon a temp fix that worked for me;

when the keyboard comes up click the small 123 button on the keyboard should be bottom right
then far left, click the red button with wrench and screwdriver
this will bring up a menu for the keyboard settings
click the last option "advanced"
then "touch input" should default to multi-touch
change this to single-touch

REBOOT

should be good to go!

The nexus7 issue is fixed (update-notifier does not pop up gksu anymore but uses pkexec which is usable with onboard).

While gksu is still broken in this regard (so leaving that bug task open) and xdiagnose still uses it (leaving that open as well) you will not get into a situation on the nexus7 where xdiagnose runs (and even if ... you wouldnt have any input method at all)

For the nexus7 i consider this issue solved (we will solve it harder by dropping gksu from the default install though)
