I installed Ubuntu (a Linux distro) on my Vaio a few months back and loved it. It was fast, it was stable and I felt I was achieving a certain amount of geeky street cred for using it!
Then, more recently there was a new version of Ubuntu released – 7.10. I upgraded to 7.10 and found the experience even better. I booted into the Vista partition on the Vaio less and less.
However, the other day when I booted into Ubuntu my graphics settings were messed up. I couldn’t get the screen to display at full resolution. I eventually decided to re-install Ubuntu.
However, I was unaware that the installer for 7.10 doesn’t seem to recognise Windows partitions the way the previous installer did and sure enough when I re-booted the Vaio after the install my Windows partition was gone 🙁
It is not too bad, the only thing I have lost afair is the time it will take to re-install Vista and all the apps I had on the Windows partition. Still, this has put a severe dent in my confidence in Ubuntu.
I referred to it when I posted about having upgraded to 7.10 last week but since then I have found how to get around it.
First the problem –
After the upgrade, browsers, mail clients and other Internet-related applications run very slowly. Loading pages in Firefox can take 30+ seconds and sending/receiving emails seems interminable too.
On inspection, the Network settings seems to forget any custom settings (I had pointed it at the OpenDNS servers). Adding the OpenDNS servers to the router’s settings didn’t help. Re-adding the DNS servers to the Network Settings helped for about five minutes when it would once again lose the configuration and slow down.
Checking the Ubuntu forums I discovered that this appears to be related to IPv6.
I tried the following suggestion and it fixed the problem for me straightaway:
IPv6 is supported by default in Ubuntu and can sometimes cause problems
To disable it, open a Terminal (Applications > Accessories > Terminal) and type the command: gksudo gedit /etc/modprobe.d/aliases
Find the line alias net-pf-10 ipv6 and change it to read alias net-pf-10 off
Everything is zinging along happily on my laptop once more!
I have had one problem with 7.10 so far and that is that it won’t remember my DNS settings. I’m not sure why that is or if it is only me. I normally use OpenDNS for my DNS – it is annoying to go back to Eircom’s significantly slower DNS servers after using OpenDNS servers for so long now.
The interface is really slick – it is obvious that lots of time and thought went into the look and feel of this OS.
It is also incredibly fast (despite being installed into a single file in the Windows partition as opposed to a normal install). From a standing start to being able to open a web page Vista took four minutes thirty seconds on this machine. Ubuntu took one minute fifty seconds on the same machine.
I’m trying out Evolution now (email client) and I will start trying other apps as well to see how they compare. For now though, I am impressed.
