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.

To-do list

Now that I’ve upgraded to Ubuntu 7.04, here’s a note to myself of things I can think of now that I still need to do:

  • Keep windows in /boot/grub/menu.lst
  • Every time there is a kernel upgrade (or after upgrading to Feisty), the menu.lst file gets changed. That file lists what operating systems choices GRUB lists upon bootup. I dual-boot between Ubuntu and WinXP. After every upgrade, however, WinXP gets deleted from the list. I have learnt to backup the old menu.lst and restore the appropriate lines of code to it afterwards, but it is annoying. So I have to find out how to tell Ubuntu to keep that choice there when upgrading.

  • Does linux keep all the old kernels around? (i.e. there are more and more options in GRUB) Can I get rid of old ones and save disk space?
  • Wireless networking
  • Before the Feisty upgrade NetworkManager has given me all sorts of headaches when trying to connect to wireless networks. Need to investigate situation now and see what needs to be done…

  • Have DVD’s autorun in VLC player instead of gXine.
  • Move the home folde to a different partition… maybe
  • Get rid of the icons for my different partitions on the desktop
  • I can access them through the > Places menu. However, do show icons for inserted media such as CDs or USB sticks. Also, I want to make the “DellUtility” Partition, that presumably is factory installed from Dell, totally disappear from view.

  • Install beagle, tracker, … desktop search?
  • Experiment with desktop effects?

…I’m sure there will be more.

Using NetworkManager for wireless networking

Finally, after much searching, trying and agonising wireless networking/internet connection is working!

Installed network-manager-gnome and wpasupplicant (or was that already installed?) through synaptic.

Created a /etc/wpa_supplicant.conf file as described here.
…but had no luck when it came to the step “Testing the configuration”. There seemed to be fewer error messages when using “wext” driver instead of “ipw” even though I have the Intel Pro/Wireless 2200BG. During testing I could tell that some things are working because different SSIDs from nearby networks were picked up, but authentication seemed to always fail (I checked and re-checked the SSID, passphrase (HEX), MAC address, etc.).

The whole time NetworkManager itself seemed to not be aware of my network adapter (i.e. clicking on the applet would only show “Wired Network”, nothing wireless).
Finally, I found this little gem of information:

“Debian and Ubuntu modified NetworkManager so that it would not manage any devices listed in /etc/network/interfaces. If you open this file and comment out the lines for the interfaces you want to manage and reboot NetworkManager will see them.”

…so, I commented out the two lines about eth1 and a reboot later NetworkManager worked just fine! Just had to select the network and enter the passphrase.

(the next day, I suddenly could no longer connect to my wireless network. After trying many things I went back to the aforementioned /etc/network/interfaces and sure enough a new line (I think it was “eth1 auto”) had appeared. After commenting that one out as well and rebooting, everything worked again.)

Note: eth1 is my wireless adapter and eth0 is the wired one.

Next: not having to enter the keyring at every log in.
I followed Part 1 of this explanation: http://www.ubuntuforums.org/showthread.php?t=316927
but only up to point 3. After that just a reboot, followed by one more input of the passphrase did the trick.

Now NetworkManager connects to the wireless network upon login without asking for any password again! 🙂

Note: some of these steps may be unnecessary for someone who uses no or only weak (WEP) encryption. The above setup is for a WPA encrypted wireless network.

Firefox speed-up

I have noticed the whole time that browsing seems to be slow. I came across this post (http://www.ubuntuforums.org/showthread.php?t=202838) and consequently changed the firefox config file resulting in a very noticeable speed-up in browsing!

In the firefox navigation bar, type: about:config
Then change this setting:

network.dns.disableIPv6 user set boolean true

(was “false”)

Note: this disables IPv6, but in future, when IPv6 gets used more/accepted by ISP, this setting should be changed back.
