I used to work on Iceweasel 3.5, which was installed by default in Debian Wheezy (testing). But after I’ve read about a new release of Firefox and its advantages (mostly how fast it is), I decided to switch.
If you want to install Iceweasel 5.0 (which is the same as Firefox 5.0) on your Debian-powered computer, there’s a simple way to do it. You just need to add:
deb http://mozilla.debian.net/ squeeze-backports iceweasel-release
to your /etc/apt/sources.list file, followed by:
wget -O- -q http://mozilla.debian.net/archive.asc | gpg --import
and then just simply do apt-get update and apt-get install iceweasel, which in fact will update your current Iceweasel installation to the latest release. (You can find more information about installation here)
I must admit that this update was a good idea – the new version of browser is much faster than the previous 3.5, which I’ve been using till now (but still not as fast as Windows version). It also uses less memory and processor. All add-ons and plugins work fine with new Iceweasel (excepting one, but it isn’t even worth to mention).

Have you ever made a beautiful chart in OpenOffice.org suite and wanted to publish it eg. on your website? Unfortunately, Calc doesn’t have this option by default (and I’m too lazy to search if there is any plugin which can do it). But you can export your charts using OpenOffice.org Drawing application – just follow those steps (tested using OOo version 3.1.1):
1. Select the chart placed in OpenOffice.org Calc and copy it (Ctrt+C).
2. Open OpenOffice.org Drawing application.
3. Paste the copied chart (Ctrl+V).
4. From the File menu, select the Export option.
5. Choose the output format (JPEG) and filename. If you want the output image to be cropped to chart size, simply tick the Selection box.
And this is the final effect:

As some of you might notice, the script acerfand (fan control for Acer Aspire One) doesn’t run automatically in th newest Ubuntu 9.04 when you add its path to your rc.local. I don’t know why, but the file rc.local behaves differently from previous version during booting (it looks like it’s not executed, but in fact it is, and when I run it manually after I log in everything works).
How did I fix it? Instead of the line:
in my /etc/rc.local file, I added:
start-stop-daemon –start –name acerfand –startas /usr/local/bin/acerfand –background
Now the acerfand script is executed at startup. I hope this tip may be helpful for somebody.
EDIT: There should be double minuses before –start, –name, —startas and –background, but – as Erwin noticed – wordpress transforms double minus into dash.

The new Ubuntu 9.04 has been released, so yesterday I decided to try it on my AAO. I preferred to perform fresh installation rather than upgrade from 8.10, because I wanted to try the new filesystem – ext4.
Hint: if you want to reinstall system instead of upgrading, and keep all your installed software, the trick is very simple – it requires using just three commands. Before formatting drive, you should save your packages list in a file by performing dpkg –get-selections > installed-packages-list in terminal. After fresh system installation, you can install all packages from the list by typing dpkg –set-selections < installed-packages-list, then sudo apt-get update and sudo apt-get dselect-upgrade. You can also edit the list and remove lines containing the software you don’t need, but you should watch out on dependencies. Reinstallation may take some time, depending on how much packages you have on your list – in my case, it took over 2h. (I found this trick here, but hte command dselect just didn’t work for me).
Installation was incredibly fast – it took about 20 minutes to install it from pendrive. (Nice surprise – wireless works out-of-the-box in live CD version!) After installation, I noticed huge improvement in booting time against the previous version (even though I was using customized kernel) – now system boots in about 30 sec, measured from grub to login screen. Login screen itself has also new, refreshed appearance, as well as the default Gnome theme.
All hardware in Aspire One works out-of-the-box, excepting the right-side card reader (the left-side one works). Even the image from the built-in webcam in my opinion is better and doesn’t frame.
OK, now it’s time to tell about bad experiences. When I logged in first time after installation, system freezed and all I saw was black screen and a pointer. Even Ctrl+Alt+Backspace didn’t help and I had to hard reset my machine. Next time everyhing was ok. I don’t know what wat the reason, maybe some of the files from my /home catalogue (which I left) weren’t compatibile with the new Gnome version. I also had problems with sound while using Skype (sometimes I couldn’t hear anything during call), I hope to fix it soon.

After unpleasant experience with Omega/Fedora, I decided it’s time to try new Mandriva, which was released some time ago. I installed it using Unetbootin and Mandriva One KDE cd image. I had some problems booting from flash drive, but fortunately this post was helpful for me.
Although almost everything is working out-of-the-box (including Wifi, Wifi switch, webcam, left card reader and internal mic), there are some hardware problems:
- Plugging-in headphones doesn’t mute speakers. I tried to edit file /etc/modprobe.d/alsa-base as suggested in Ubuntu Install guide, but I couldn’t find this file. So I created it and tried with different options, but it didn’t help.
/etc/modprobe.d/alsa-base >> options snd-hda-intel model=acer – I didn’t notice difference
/etc/modprobe.d/alsa-base >> options snd-hda-intel model=auto – mic doesn’t work
/etc/modprobe.d/alsa-base >> options snd-hda-intel model=basic – the same as above
/etc/modprobe.d/alsa-base >> options snd-hda-intel model=toshiba – I got no sound at all.
- Right card reader works only if card is inside during booting. To become fully-functionall, it require some tweaks (also from Ubuntu forum):
download this script, make it executable (chmod 754 jmb38x_d3e.sh), copy it to /usr/local/sbin, edit as a root and modify line 11: ‘modprobe pciehp pciehp_force=1’. Then add ‘setpci -d 197b:2381 AE=47’ to /etc/rc.local.
This should make card reader working, but in my case it disabled acerfand script, or increased processor temperature (I’m not sure what exactly but I could hear fan working all the time after I ran the script).
- Wifi led seems to work only with madwifi drivers, not with those included in kernel 2.6.27 (it didn’t work also in Ubuntu
- Also some keyboard shortcuts (with Fn key) don’t work, I had to configure it manually.
I also installed acerfand script – after updating bios to v0.3305, it works again.
About Mandriva itself – in my opinion it’s really fast, maybe even faster than Ubuntu, and booting time can be comparable to XP. However KDE4, despite its nice appearance, is still unstable and lacks usability.
I haven’t tried LXDE yet – the special desktop environment for netbooks. I just didn’t have time. I don’t know if I will try it – now I’m looking forward for tomorrow’s Ubuntu release 🙂

Today I installed on my Aspire One Linux Omega beta – distribution based on Fedora (actually, it is Fedora with a/v codecs and multimedia applications installed by default). After running, system looked really ugly – because of my previous Ubuntu installation (I’ve kept my /home directory) – i had to do some visual tuning and turn Compiz off. any However, the new Fedora kernel recognized my Wifi card, which was working out-of-the-box, as well as left card reader.
After this happy welcoming, unpleasant surprise has came – when I wanted to upgrade the system, I couldn’t add software sources – after clicking on any of them, and waiting few minutes (!), I was getting message about some error. I reallised it’s time to say goodbye to Omega… Well, I cannot use distribution without ability to install new software! Or, maybe just beta version is not for me.

I bought myself new notebook. I considered three models: Asus Eee PC 901, MSI Wind U100 and Acer Aspire One, because something small, light-weight and mobile was what I exactly need. My final choice was the last one of these three – Aspire One 150, with Intel Atom 1,6GHz, 1024MB of RAM memory and 120GB of hard disk space on board. Why this model? MSI was unavailable in the place where I’m living now. Asus Eee PC might be a good choice, but I heard the lifetime of SSD drives is limited, and only 20GB of disk space is definitely not for me. Unfortunately, the configuration with 120GB hard drive had also Windows XP included, but I managed to install the newest Ubuntu 8.10 on it. I also tried with other distributions, but Mandriva was unable to detect all my hardware (maybe I should to wait to next release, which – I heard – will have support for netbooks), Fedora didn’t look pretty on my small 8,9″ screen, and I got some errors trying to install other distros using USB pendrive (I haven’t bought external DVD yet). All hardware in my AAO works properly on Ubuntu, excepting card readers – memory cards are recognized only if inserted while booting.
However, the battery lifetime in my One could be longer, and the only one thing I have to get used to is uncomfortable, small touchpad.
