Ubuntu: disable Alt to launch HUD

September 26, 2013 Leave a comment

Problem
In Ubuntu (with Unity), Alt launches the HUD. Fine. However, if you have a Windows in VirtualBox and you want to switch windows in the guest VM with Alt+TAB, that damn HUD always appears in the host. How to disable it?

Solution
I found the solution here.

In short: top right corner, System settings… -> Keyboard -> Shortcuts tab -> Launchers. Assign a new key to “Key to show the HUD“, or disable it completely by pressing the Backspace.

Disable Unity’s F9

Problem
I use Midnight Commander a lot and F9 in MC means: “go to the top menu bar“. However, Unity steals F9 and activates a widget layer. By default this layer is empty, so you only see that the screen greys out.

How to disable this shit?

Solution
Start “ccsm“, find the Desktop section and untick “Widget Layer“. Done.

Make room! Make room!

Problem
Under Gnome/Unity, you want to increase the number of virtual workspaces.

Solution
Start CompizConfig Settings Manager (ccsm), then General -> General Options -> Desktop Size tab. Here adjust the horizontal and vertical virtual size.

The title of this post is a reference to a novel of Harry Harrison.

Tweak your Ubuntu

January 3, 2012 Leave a comment

Ubuntu Tweak is an application to config Ubuntu easier for everyone. It provides many useful desktop and system options that the default desktop environment doesn’t provide.

UT is provided in .deb format, so its installation is trivial. You can start it with “ubuntu-tweak“.

I find the following options particularly useful:

  • Under Tweaks -> Miscellaneous, you can put back the icons to menus and buttons.
  • Under Tweaks -> Compiz Settings, you can assign window operations to workspace edges.

What to do if the sidebar of Unity is stuck

September 5, 2011 Leave a comment

Sometimes my Unity sidebar is stuck. Fortunately I found a solution here:

The way I figured how to get it to hide again is go to somewhere like an internet page and click and drag across some text to high light, then click in the highlighted text and drag away like you’re going to place it somewhere else where you’ll see the hand in a fist, the transparent text, and a plus sign, and the side bar will hide again once you release the button.” (source)

Ubuntu 11.04 Natty Narwhal

April 29, 2011 5 comments

Yesterday I installed the newest Ubuntu on my machines. The upgrade went smoothly, there were no problems. I collect here my notes about this new release.

If you want to upgrade several machines, read this post. With this “trick” you can reuse the downloaded packages on other machines too.

Unity redefines F10. As I use Midnight Commander a lot, it’s quite annoying as F10 means “quit” in MC. A workaround is to use ESC + 0 in MC, but that’s a PITA. Also, I assigned something to F10 in vim… Here is how to disable F10 in Unity: (1) install compizconfig-settings-manager and start it, (2) filter “unity” and start the Ubuntu Unity Plugin, (3) edit “Key to open the first panel menu” and disable it. Now everything is back to normal.

With CTRL + ALT + T you can start a new instance of your default terminal emulator. I use terminator, so here is how to make it the default: click on the power button in the top right corner and choose “System Settings”. On the left side at the bottom you will see “Set Preferred Applications”. Start it, and under the System tab specify your favorite terminal emulator.

Want to monitor the RAM / CPU usage? Execute the following commands:

sudo add-apt-repository ppa:alexeftimie/ppa
sudo apt-get update
sudo apt-get install indicator-sysmonitor
indicator-sysmonitor &

I use this customized output: “| CPU: {cpu} | RAM: {mem} |”. To edit it, right click on the applet and choose Preferences.

Is the Dropbox indicator applet gone? Here you will find a fix.

Missing the weather indicator? Execute “sudo apt-get install indicator-weather“. (via webupd8)

Unity wallpapers with shortcuts: here.

After playing one day with Unity, I found one thing very frustrating: there is no bottom panel for the applications, so I never know what programs are running. I noticed that I was pressing ALT + TAB a lot… I was already thinking of switching back to Ubuntu Classic when I could figure out how to get the bottom panel back. You just need to launch “gnome-panel” and customize the new panel. Add it to your startup applications, this way it will be launched each time you log in. It also added a top panel that I removed (right click, delete). Customization: right click and add “Window List” and “Workspace Switcher”. Since this is a classic panel, you can add all those applets that are missing in Unity, for instance the “System Monitor”.

If you find the global menu (File, Edit, etc. are on the top panel like in MacOS) annoying, here is how to get rid of it (via webupd8):

sudo apt-get remove appmenu-gtk indicator-applet-appmenu indicator-appmenu

Log out and log back in to take it into account. (edit: same thing in 11.10)

Under Eclipse I had a strange problem. Sometimes it crashed with the error message “The program ‘Eclipse’ received an X Window System error.” I found the solution here. In short, I had two xulrunner instances on my system, versions 1.9.1 and 1.9.2. Fire up Synaptic and remove 1.9.1.

With Firefox, I also had some strange problems. I couldn’t drag and drop an URL from the location bar to the Bookmarks. Or, sometimes the popup menu activated with the right mouse button disappeared when I moved the mouse pointer above it. The following command solved these problems:

sudo apt-get remove firefox-globalmenu

If you don’t like the new overlay scrollbars, here is how to get rid of them:

sudo apt-get remove overlay-scrollbar liboverlay-scrollbar-0.1-0

This tip is from here.
