Inkscape user interface functions don't work

[Carl Symons]

Starting with the upgrade from Kubuntu 11.04 to 11.10, Inkscape functions for fill&stroke and align don't work. Clicking the icons or using keyboard shortcuts cause the HD activity indicator to light, but nothing happens on-screen. This doesn't appear to be an issue for other Inkscape users based on response (and lack of) from the Inkscape Users mailing list.

Possibly related UI problem (filter primitives in the filter editor can no longer be drag&dropped in Inkscape on new Kubuntu 11.10 installation):

If the problem is related to gtk, then there may be another issue...

GIMP doesn't work properly either
some functions work, but selection-copy-paste as new layer produces no result. I haven't tried all functions.

Please advise if this should be posted elsewhere.

Thank you
Carl

This "bug" should be closed or moved to a forum.

The problem is related to
System Settings > Application Appearance > GTK+ Appearance

changing GTK + styles, Widget style (dropdown) to Raleigh made Inkscape and GIMP work properly. After launching both apps, changing that Raleigh to oxygen-gtk made them look purdy.

From the dependencies:
> libcairo2 1.11.3+git20111015.3813066f-0ubuntu1~11.10~ricotz0

You seem to have installed an unstable version of cairo (development snapshot from git master - unlikely the default on (K(ubuntu) 11.10) - do these interface failures also occur with the current stable cairo version (1.10.2)?

Any other custom packages installed which might interfere with gtk2 and gtk2 theme engines on Kubuntu?

Unstable version of libcairo2 comes from ppa xorg edgers
Fixed the immediate issue by changing the GTK+ Appearance in System Settings to Raleigh and then back to oxygen-gtk

Works fine.

Downgrading libcairo2 has apt-get wanting to upgrade. Getting that back to stable state would involve deactivating xorg-edgers repository...and there are some intel driver goodies in there that are needed for best performance on this machine.

Thank you
Carl

Closing as 'Invalid' for Inkscape based on user feedback - please reopen if you think this was done in error and the problem with the 'oxygen-gtk' theme under current KDE/Kubuntu needs to be addressed in Inkscape's code.
