Upgrade from Ubuntu 12.04 to 12.10, Ubuntu 12.10 Review

This week I decided to upgrade to the latest release of Ubuntu, 12.10. I had thought about using 12.04 LTS until the next LTS came out, but I was getting a little tired of random Compiz crashing, and I was just generally curious. Here is my review of some of the differences, experiences, and new things I found in 12.10 that mattered to me.

Setup

I started the install on my  HP G42-415DX with ATI Mobility Radeon HD 4250 Graphics and 8GB of RAM.

Install

After backing up my home folder, I decided not to upgrade, but to just install fresh by electing to erase my hard drive and start fresh. The install was rather quick over a USB live install of 12.10. Once the install was over it booted, rather quickly I might add, into the login shell. I noticed that I could no longer select 2D when logging in (which I expected).

No restricted drivers, everything worked out of the box hardware wise. I will say that this install was the best ever using Ubuntu.

Performance

The default video drivers performed perfect and I haven’t touched them. I did find Unity much slower than 12.04, but it seems to help to remove some of the lenses, but it’s still slower than 12.04. Other than that everything has performed pretty much the same. I did find the video to be much snappier and responsive, less static and flashes too. Dual displays worked great!

Visual Differences

Tabs were re-done to appear much nicer and buttons are smaller. The notification area has been made simpler, if there is only one user the user-switcher does not show up. The launcher works crisper and animations seem to be a lot better. In 12.04 I was always frustrated with it’s usability and notifications. In 12.10, when a notification is thrown, it properly pops out the icon so you notice.

Otherwise it’s pretty much the same. Unity has square highlights vs rounded highlights too.

Applications

Empathy got a good work-over and I feel it looks a lot better. Online accounts (which Empathy uses) is in the Settings panel. Gwibber does not work at all. The notification applet also always shows you as offline.

The best part is that ALT-TAB does not fold tabs in Chrome. This was really annoying in 12.04 as I had to ALT-TAB through each tab in Chrome.

Overall

If you are wondering if 12.10 is worth it, I would suggest it is. The removal of restricted drivers and more “just working” makes it a great release.  But, as always, your hardware setup will always change things. I’m glad I upgraded.

Setting up Ubuntu Server as a Virtual Machine (in Virtualbox) and using Subversion (svn) for the first time to checkout Google Code using shared folders

[iframe src=”http://blip.tv/play/h61qgsXLEQA.html” width=”100%” height=”378″]

In this screencast I explore using Subversion (svn) to checkout Google Code using Ubuntu Server in a virtual machine (using VirtualBox). The purpose of this screencast was two-fold.

  • First, I wanted to setup a Linux environment to use on Windows 7 for actual Linux stuff. As part of this I had to setup shared folders to the host operating system from the guest.
  • Second, I wanted to use Subversion (svn) to checkout some code (for the first time, for me).

So, in this screencast we will be:

  • Setting up a Virtual Machine and installing Ubuntu Server (10.10)
  • Setting up the required dependencies to install VirtualBox Guest Additions
  • Setting up VirtualBox Guest Additions and setting up and using shared folders on the host system
  • Installing and using Subversion (svn) to checkout some Google Code
  • Taking a snapshot in VirtualBox of our successful setup

This has been put in Code & Development because I will soon be using the virtual environment to run a local LAMP server (for a later screencast).

Ubuntu 9.10 Dell Mini Suspend with SD Card

Ubuntu /usr/sbin/pm-suspend 9.10 SD Card umount

I always keep an SD memory card in my Dell Mini so that I can put whatever on it to save space on my solid-state. So, this morning, I have been installing Ubuntu 9.10 on my Dell Mini 9 and everything went better than ever, installation-wise. But, as soon as I closed the lid, the machine froze. Of course, like all Linux users, I pulled up Google for a fix, and found one:

Ubuntu 9.10 Get SD card path

Ubuntu 9.10 Get SD card path

I edited the /usr/sbin/pm-suspend script and before the script did anything, so right before the “# The rule here? Simplicity. I added,

umount /media/<SD Card Mount-point>

To find out the mount point (or path), just insert your SD card, find the pencil by the location bar in the file browser and copy the path it gives you.

Ubuntu 9.04 NR Suspend/SD Card Problem on Dell Mini 9

So, I decided to install Ubuntu 9.04 NR after starting my semester as a Computer Science Major, main reason, gcc. Plus, the Linux itch was getting to me, thought I’d give it a try again, give it another go.

But, right away, Ubuntu was running fine, of course with some of the usual drop in experience from XP: slow video, slow Firefox, etc. Even thought I still feel bad for grandma and still have no hope of her enjoying the Linux experience, I found a few tweaks to help:

But, other than that, Ubuntu is still not quite running well enough to give it even a B+, you get a C+. As we speak last.fm in Rhythmbox is skipping once in a while! But, that’s not what this post is about.

This is about when you close your lid on your Dell Mini 9, nothing comes up when you open it up except a cursor. After thinking for just a few hours, I figured it out, if you have an SD card in the slot, and sleep it, you are going to keep getting that. So, now, you have to remove the SD card before suspending the computer! Annoying, still wondering why I let the Linux itch get to me (as Last.fm keeps skipping and typing is freaking out, writing this post).

Bah!

Fixed: I had recently tried installing Ubuntu UNR on the SD card and had not formatted it since. After formatting the card (FAT16), it sleeps! Check out http://ubuntuforums.org/showthread.php?t=208980 on how to format your card.
