view story

http://ubuntuforums.org – I just upgraded my 12.04 box to 12.10. I have a few problems: 1) In 12.04 I added google's repo to install chrome. Web apps are not working with chrome for me right now 2) I installed chromium from the software center. Web apps are not working from chromium 3) I opened gmail from firefox. It almost looked like webapps were going to work with firefox as I got a popup from gmail to enable desktop functionality. However, I don't get a gmail icon in sidebar, and none of the webapp integration is present on my ubuntu! 4) I saw in a youtube video that gimp was integrated with unitu (Hardware)
