go to settings > devices > keyboard
look for the keyboard shortcut for "Switch windows"
set this to the shortcut Alt+Tab (this will overwrite the old shortcut)
If you now press Alt+Tab you will be able to directly select all open windows without grouping into the different apps.
Come April 26th and the release of Ubuntu 12.04 a vast number of Ubuntu users will be getting their first taste of the Unity desktop since its basic beginnings as the Ubuntu Netbook Remix in the last LTS. But for all of the innovation, aesthetics and features that the unity desktop offers there is a chance that, for many, the change will be too much. But Unity is only one desktop environment available to install in Ubuntu.
This section discusses helpful tips for getting GDM working. In general, if you have a problem using GDM, you can submit a bug to the "gdm" category in bugzilla.gnome.org or send an email to the<gdm-list@gnome.org
Referencer is a Gnome application to organise documents or references, and ultimately generate a BibTeX bibliography file. Referencer includes a number of features to make this process easier: * Smart web links Referencer uses documents' metadata to provide handy links to the document's web location — no need to maintain your own bookmarks. * Import from BibTeX, Reference Manager and EndNote No need to start from scratch — Referencer will import your existing bibliography files using the BibUtils library. * Tagging No need to organise your documents into rigid directory trees — with Referencer you can use tags to categorise your documents. * Automatic arXiv, PubMed and CrossRef metadata retrieval If you show Referencer a PDF which has an arXiv ID or DOI code, Referencer will retrieve the metadata for this document over the internet. * Python plugin support Referencer can be extended using the versatile Python scripting language. * Localisation
Well, first, getting a new URI scheme to be handled by Firefox is equivalent as getting it handled for Gnome, since for some reason, Firefox uses the generic gnome-open command to handled unknown URI schemes. I haven’t been able to find how or why, so I don’t know if that’s Debian specific or if this is true for any Firefox running on Linux et al.
This tutorial will cover the basics of the GNOME desktop environment and application framework. GNOME uses the GTK and GNOME API to provide the software developer interfaces.
Compiz nutzt eine komplette Hardwarebeschleunigung, das bedeutet, Fenster werden in Texturen verwandelt und direkt auf der Grafikkarte zum sichtbaren Desktop zusammengesetzt. Das Verschieben eines Fensters wird so fast komplett von der Grafikkarte übernommen, indem eine Textur verschoben wird. Dadurch wird der Prozessor stark entlastet. Gleichzeitig können die Funktionen der Grafikkarte genutzt werden, um die Texturen zu manipulieren. So kann man beispielsweise näher an ein Fenster heranzoomen, hat also eine eingebaute Bildschirmlupe.
Die Hardwarebeschleunigung macht auch die vielen Effekte möglich, die Compiz so bekannt machen. Beispielsweise können sich die Texturen beim Verschieben verformen, zu einem dreidimensionalen Würfel zusammengesetzt werden oder beim Schließen eines Fensters verbrennen.
First of all, I don't run Compiz because I see it as no more than a resource-wasting annoyance. Sure, it looks cool, but it doesn't help me with productivity in any way. Secondly, I keep multiple windows open at all times, so I rarely see my desktop and it was good to see that GNOME shell includes a window switcher which can be accessed with the traditional Alt Tab hotkeys. Finally, my system isn't a high-end system. I build my computers because it allows me to pick and choose hardware that I already know works with GNU/Linux. GNU/Linux, if you know what you're doing, doesn't need the latest and greatest hardware.
Getting Back to a Pure KDE on Ubuntu Note, this applies only to Ubuntu 9.04 (Jaunty). If you're using 8.10, go here. If you're using 8.04, go here. These removal commands were created based on what Ubuntu or Xubuntu packages were added to a default Kubuntu installation. It's possible that the commands might remove some other packages you have since added to the default and want to keep. If that's the case, keep track of which packages those are and reinstall them. Your settings should still be there. Remove Ubuntu
