Upgrade to Ubuntu 11.10 on Acer netbook

I tried to upgrade my Acer Aspire One (AOA150) from Natty to Oneiric, but failed. So, I did a fresh install instead.

Upgrade experience: All seemed fine at first, but somehow the screen went black during the upgrade process and would not come back at all. There seemed to be some activity, so perhaps the upgrade was proceeding fine, but I had no way to tell. So I forced the computer to shut down, downloaded Ubuntu to a USB stick and started a fresh install.

Fresh install: Proceeded without a hitch. Obviously, everything on the computer was wiped out. This would have been a disaster on my main computer, but for the netbook it is fine because there is nothing personal on it, anyway. Only copying the music back onto it will take a bit of time.

Things to do after install: A couple of things to make it work the way I want it to…

Installing Google Chrome (not Chromium):
Download chrome installer, then…
sudo dpkg -i google-chrome-stable_current_i386.deb
sudo apt-get -f install

…the latter to resolve some dependency issues with the browser.

Skype:
Installed skype from the software centre, but microphone wouldn’t work. Sound recorder could record fine, however.
To fix this, I installed pavucontrol, and changed the input to 10 on one side and 90 on the other (after unlocking the left and right channels).
This is explained here: help.ubuntu.com/community/SkypeTroubleshooting

Most built-in mics are mono. The default setting on the Input Control is to lock the R&L channel together. By reading the mono mic as stereo, PulseAudio cancels the input. Click on the middle button on the upper right of the control panel to unlock the R&L channel. Move either the left or right channel to 10 leaving the other channel about 90.

Autologin to 2D:
When setting Ubuntu to automatically login as a user, it defaults to Unity (normal, i.e. with compiz and “3D”). To speed things up, I want it to autologin to Unity-2D. Here’s how:
In the file /etc/lightdm/lightdm.conf, change
user-session=ubuntu to user-session=ubuntu-2d
.. as explained here: askubuntu.com/…/how-to-default-to-unity-2d-on-auto-login

Network:
Luckily the netbook is hooked up to the network by wire, otherwise connecting to wifi would require a password (very annoying when wanting to use autologin). I set wireless to NOT connect automatically.

Final note: I like that in the touchpad settings I can now set it to two finger-scrolling.

Lucid Lynx

am a bit late, but have now installed Ubuntu 10.04 Lucid Lynx 64-bit (on a dell Studio 1747).

The installation went without a hitch, here are the major things I had to do afterwards. Actually, nothing major, mind you.

Wireless network: install required wired network, and then activating the Broadcom STA proprietary wireless driver ( > System > Administration > Hardware drivers)

Sound: No sound would play through the headphones. Solved by adding the following line to /etc/modprobe.d/alsa-base.conf
options snd-hda-intel model=dell-m6

…other issues and notes later.

Hardy Heron / Ubuntu 8.04 install

I have just upgraded to Ubuntu 8.04, and thus there are some new things to blog about.

I could not actually upgrade, as I got this error every time I tried:
Could not calculate the upgrade
A unresolvable [sic] problem occurred while calculating the upgrade.

So, guessing that it may be caused by “unofficial software packages not provided by Ubuntu” I uninstalled/disabled the following:
BlueMarine, easyTAG, Firefox add-ons, flashplugin-nonfree, Flock, Gnomad, GQview, gstreamer plugins bad, ugly and ffmpeg, gxine, libdvdread3, LightZone, MPlayer, multiverse sources, NVidia restricted drivers, Picasa, pysdm, Skype, Sun Java, VLC
Still, every time I tried upgrading the same error popped up.

So, instead I did a fresh install of Ubuntu, which went well. I don’t find the partitioning part well done for someone who’d like to keep his existing Windows installation. I chose manual configuration, deleted the existing Ubuntu (7.10) partition, and chose to reformat it as ext3 as root partition… all the while not being sure whether I was doing the right thing…

Upgraded to Feisty

I have just upgraded to Feisty Fawn (i.e. Ubuntu 7.04) and it all went so smoothly there is nothing to write home about. I’m almost disappointed 😉
I took an hour of letting the upgrade tool do its work.

The only small annoyance that I have noticed so far is that it changes menu.lst the way it always does when you do a kernel upgrade. It takes Windows off the list, which is quite annoying for a dual-booter like me. More in another post.

More software sources, but are backported updates a good idea?

Immediately after installation the Update Manager prompted to downloaded 100+ MB of updates …did that.

> System > Administration > Software sources: enabled more software sources (universe, main, multiverse, restricted, source code), checked boxes to receive security, recommended and proposed updates. Still have to decide/research whether to also get backported updates.
I wonder if I can specify that only backported updates for certain applications are received but not for others? I may want to have some backported features in the future. However, I would not want Ubuntu to apply all available backports to all installed programs, as I guess that may compromise system stability. Or am I wrong??

Allowed Ubuntu to get anonymous software statistics so that hopefully the applications that I use most get maintained well.

…the new sources triggered more updates to be downloaded and installed …did that.
