Ubuntu 12.04 Precise Pangolin beta 2 – Disable Sticky Edges & Display one launcher, at last :-)

What’s new in Ubuntu 12.04 Precise Pangolin beta 2 since beta 1

Unity (both 2D and 3D) gained an option to configure the launcher for multi-monitor setups: you can now select to display the launcher on the primary monitor or on all monitors. The Launcher behaviour for multi-monitor setups can be set from System Settings (Displays, under Launcher Placement). Under System Settings, you can now also enable/disable Sticky Edges:

What can go wrong? Hitting the: “update-manager -d” to PrecisePangolin 12.04

Ubuntu
PrecisePangolin
12.04
Beta1
OK…
Lets do it :-D

Terminal: sudo update-manager -d&

---

And… back up and running :-)

Downloading the files took 30-45mins, the configuration and updating about an hour.

Reboot was quick and then straight back in to 12.04 after login.

Next up was 20 seconds of scary white screen with black dots… then Tada!

Both screens clear to show my desktop.

Both monitor screens now have a launch bar, whereas before there was only one.

Sweet :-)

Precise Pangolin Ubuntu 12.04 Release Notes

Cant find the release notes?

I think they are now called “TechnicalOverview” :-)

https://wiki.ubuntu.com/PrecisePangolin/TechnicalOverview/Beta1

Get Ubuntu 12.04

Upgrading from Ubuntu 11.10

To upgrade from Ubuntu 11.10 on a desktop system, press Alt+F2 and type in “update-manager -d” (without the quotes) into the command box. Update Manager should open up and tell you: New distribution release ‘12.04’ is available. Click Upgrade and follow the on-screen instructions.

To upgrade from Ubuntu 11.10 on a server system: install the update-manager-core package if it is not already installed; launch the upgrade tool with the command sudo do-release-upgrade -d; and follow the on-screen instructions. Note that the server upgrade is now more robust and will utilize GNU screen and automatically re-attach in case of e.g. dropped connection problems.

Upgrading from Ubuntu 10.04

There are some known issues at this time, so only developers and testers should try doing this upgrade at the moment. (927993)
