Ubuntu 12.04 problems with NVIDIA® GeForce® 8400M

So finally I’ve got my old laptop working with the current Ubuntu 12.04 release.

To do this I’ve followed this user advice and completely removed the proprietary NVIDIA driver:

sudo apt-get --purge remove nvidia*
sudo apt-get install xserver-xorg-video-nouveau libdrm-nouveau1a nouveau-firmware

Reference: [8400m] nvidia-graphics-drivers (295.33-0ubuntu1), is causing failed restarts. shutdowns & only a blackscreen on tty’s other than tty7

Unity Launcher Editor in Ubuntu 12.04

To run the Unity Launcher Editor in Ubuntu 12.04 you need to run the following commands in the Terminal:

sudo apt-get install bzr
bzr branch lp:unity-launcher-editor
cd unity-launcher-editor/

I’ve noticed that many bloggers are telling you that you should run it by using the “~/unity-launcher-editor/unitylaunchereditor/main.py”, but that file no longer exists.

Small UI failures on Ubuntu 12.04

Today I’ve upgraded to the new Ubuntu version 12.04 Precise Pangolim and I found that some UI needs to be updated to 2012 year! ;)

Missing tooltips in the “Dash Home”

Basically when an UI is intended to mouse point usage it should show tooltips when you hover over some button. The “Home”, “Files”, “Music” and “Video” icons are well understood, but the “Apps” icon makes no sense… To solve this when you hover over those buttons it should appear a tooltip like “Show Applications”/”Show Vídeo Collection”…

Missing visual feedback when opening apps outside the Launcher bar

Ok this is another weird ( I say weird, because it’s weird that in 2012 things like this still happen) issue on the UI, that don’t show any type of feedback to the user while he is waiting for the app to launch. Loading indicators are a standard and they are a standard for a reason, don’t you think?

Ubuntu 10.10 gnome-power-manager shutsdown bug

Actually I don’t know in which version this bug has started, but “gnome-power-manager” just indicates that my laptop battery is charging even though I unplug the AC power supply.

Since I upgraded to the new version, the problem is even worst, since now when I unplug the AC power supply  a message pops up saying that I have less than 1% battery power and Ubuntu just shuts down.

Actually if you have this same problem, you can go to “gconf-editor” and where it says “/apps/gnome-power-manager/actions/critical_battery”, set it to “nothing”

Screenshot-Configuration Editor - actionsThis actually doesn’t solve this bug, but at least you can use Ubuntu!

How to configure Pidgin 2.5.2 in Ubuntu 8.10 (intrepid ibex) to use Google Talk

Pidgin it’s a chat client that support multiple protocols like:

  • AIM
  • Google Talk
  • IRC
  • MSN
  • MySpaceIM
  • XMPP
  • and more…

To install it in Ubuntu just run in the console:

sudo apt-get install pidgin

The first time you open it, it asks you to add an account:

Pidgin add account
Pidgin add account

Then you can choose which protocol to use. Here I’ve choosed “Google Talk” protocol and put my login info:

Pidgin with Google Talk protocol
Pidgin with Google Talk protocol

And its done :)
