And make it an application you can add to lubuntu panel.
Create the following file /usr/share/applications/mtpaint-grab.desktop containing :
[Desktop Entry] Encoding=UTF-8 Name=Grab screenshot Exec=mtpaint -s Icon=camera Type=Application Terminal=false Categories=Application;Graphics;
You can now add it to the Application Launch Bar in the Panel.

June 2010 – Apparmor
What a subject.. We’ll step out of the T&T section this month to visit the Security Discussions area.
bodhi.zazen spends a lot of time in this section, educating and providing support.
apparmor (Application Armor) does what its name suggests, it helps protecting the system if an application gets compromised. apparmor works with specific application profiles that regulate and define the applications access in addition to the usual system permissions (which apparmor can only restrict).
By default, Ubuntu comes with apparmor profiles for CUPS, evince, dhclient3, firefox (which is not enabled) and the guest session.
The first thread to read is Introduction to AppArmor which is closed for posting. Two other threads are open for discussion:
Share your AppArmor Profiles and AppArmor Support Thread.
Enjoy the readings, test it out and report back in the threads!

I’ll make an exception and place the subject of the Tutorials in the title, as upgrading to karmic could turn being a nightmare to some.
I’ve stepped out of the Tutorial & Tips section to visit two tutorials, one of them in T&T, the other one in the current Karmic Development section. Both threads will let you know everything you always wanted to know about grub2 (but were afraid to ask). Both are from drs305. grub2 is default with Karmic and can be installed on Jaunty.
The first one, “GRUB 2 Basics” will get you started with grub2, in particular with the /boot/grub/grub.cfg and /etc/default/grub files. The second one, “Grub 2 Title Tweaks Thread” will help you tweak grub2 titles to your desire. Before upgrading to Karmic, make sure you read both of them!
Special mention to ranch hand‘s “Grub2 Introduction” for links to documentation.
Quite often, there is a delay between latest stable application version from an upstream project and updated version from the Ubuntu repositories. This gap is quite important with ALSA. Here is a tutorial from soundcheck that will help you install the latest official stable ALSA release: “ALSA Upgrade Script“. The script should be used with caution as it installs packages itself without going through official repositories. A restore option is provided to reinstall sensitive packages and get them back to their previous Ubuntu version. Many sound issues appear to be solved by this tutorial! Sound should be treated like video via restricted hardware..
Enjoy :)
DSDT (Differentiated System Description Table) is in the BIOS and this is where the OS looks for hardware and configuration info. It sometimes needs to be adjusted, in particular regarding ACPI. 67GTA has written a comprehensive tutorial for Ubuntu and Linux Mint: “HOWTO Fix A Buggy DSDT File” which currently works only up to Jaunty 9.04 release. I’m not sure I understand all the details, but reading through the thread, members seem to be able to fix a large range of ACPI related issues.
Credits to unutbu who suggested the tutorial. As unutbu puts it:
It is kind of amazing (at least to me) that fixing one file can solve such a variety of problems.
The feature had been deactivated due to database corruptions issues with the plugin. After the devs rewrote the code, ubuntu-geek made it available again. You’ll find it under the Thread Tools menu. You can only mark your own threads as solved. The action can be reverted and the thread marked as unsolved.
This week, we step again out of the Tutorial & Tips section of the forums, to highlight psyke83‘s gigantic HOWTO: Jaunty Intel Graphics Performance Guide. Intel graphic hardware is quite popular and Intel drivers code has been extensively developed. Jaunty has some problems with the latest intel drivers or acceleration method. You can choose one of the three proposed methods, from safe, to optimal and the always risky bleeding edge.
We hope this will help ou with Intel video chips, please feel free to post your questions in the thread, psyke83 is actively supporting his tutorial.
See you next week !
A year and a half ago, K.Mandla started a nifty Tutorial of the Week project. The project goal is described here. Basically, we try to push forward tutorials that are clearly written and well supported by the author. If you wish to have an idea of what we expect for tutorials, please see here.
K.Mandla has moved to other fun projects, you can still follow them on Motho ke motho ka botho :)
That was quite unfortunate for us as UF team, and in particular for the Tutorial of the Week. I dearly miss you, K.Mandla.
After much discussions about refining the tutorials review process (this takes time, skills and dedication), I decided to dive into reviving the project that was missed by many members. I’ll do my best, although I know I’ll never get near to K.Mandla’s art..
Please feel free to nominate tutorials here or in the UF discussion thread, that will help us, thanks!
I’ll write later about the tutorial review process. We have quite a few ideas, but we do not have a consensus yet.
So, Tada! please have a look at this week’s featured thread:
This is a nifty tutorial that will show you how to successfully compile the subversion MPlayer under Jaunty Jackalope. For memory, ubuntu-freak‘s “Comprehensive Multimedia & Video Howto” was the Tutorial of the Week for October 06, 2008 and should be used if you do not wish to compile applications.
This tutorial is very well presented, and, most of all, supported. You can even browse a recent tutorial from the same author, “Top 10 Tricks and Tips for the svn MPlayer” that focuses on MPlayer usage. Long hours of fun ahead!
The ubuntuforums have become the largest GNU/Linux forums worlwide. With the expanding community, the crew taking care of the forums and the forums categories and features have grown with time. It is easy for new people to get lost within such an active message board. We currently have 793,387 members and 65,554 active members (members who have posted at least once in the last month), 995,019 threads and 6,367,064 posts after a heavy Spring cleaning. Here is a little summary of the important links to keep at hand:
Ubuntuforums is a large house, we try to keep it pleasant and helpful. See you there!
