Upgrading to Ubuntu 12.04

Ubuntu 12.04 running Gnomce Classic with Cairo Dock

I recently upgraded several PCs to Ubuntu 12.04, either from 11.10 or from 10.04. Most upgrades went just fine apart from one, on the Dell Latitude D505 which for some reason didn't download half the updates and had to do a sudo apt-get upgrade afterwards to get them all installed. It is apparently not recommended to upgrade from 10.04 to 12.04 until 12.04.1, though I had no problems doing so on one PC I tried. On my main desktop I did have to change my Gtk theme to Adwaita since the theme I was using (Ambiance Blue) has not been updated to work with 12.04 yet, and is simple to switch using Ubuntu Tweak.

12.04 just feels like a slightly more polished version of 11.10, but this might be because I don't use Unity, which apparently has had a lot of improvements. I did try it again briefly and it's good that there's now an option to have the dock on each monitor or not in a multi-monitor setup. However I still prefer to have a dock (I use Cairo Dock) on the right hand side of my right-hand monitor, which isn't possible with Unity, so I use Gnome Classic which is, thankfully, still available in 12.04. Also Unity would be far better without the annoying Global Menus, which are not conducive to multi-tasking for me, and I don't want everything to full screen all the time.

I also tried the standard Gnome desktop, it is slightly better than Unity in some ways, apart from it needs decent hardware acceleration and the virtual desktops don't work properly on dual monitors (switching only works on main monitor). It also seems it needs more tweaking than Classic to get it how I would want it and in Gnome I miss my wobbly windows! The only thing I like about Gnome Shell and Unity is both have a good search function, it's easy to search for apps and files, other than that they both miss the mark for me. The search function in nautilus is fine for searching for files for me at the moment.

Overall, 12.04 brings quite a few other improvements over 11.10 such as better battery life, the new Privacy Manager feature in System Settings, and many others. In fresh installs, Tomboy has been removed (I've recently switched to using Evernote instead so I probably won't install it on fresh installs), and Rhythmbox has replaced Banshee as default music player. This does not bother me since I mainly use Gmusicbrowser which is far quicker and lighter than either of those, it scans my large mp3 collection in no time at all, unlike Banshee and Rhythmbox which seem to take hours! Ubuntu 12.04 is a solid LTS release, and well worth upgrading to, though I (and Canonical) would recommend waiting until 12.01.1 to upgrade PCs running the previous LTS, 10.04, or consider fresh install if you cannot wait!

upgrade to 12.04 on dell d505:
I plan to upgrade soon on my d505.

is 12.04 running reasonably fast? Which desktop do you use? I have BC 4309 WIFI card: did you have problems to install WIFI?
Any further advice?

The D505 doesn't run any slower with 12.04 as long as it isn't running Unity. I use either Gnome Fallback aka "Ubuntu Classic" desktop or XFCE/Xubuntu desktop which is slightly quicker. I did have some problems getting Ubuntu 10.04 installed originally but I'm not sure whether these problems occur with a fresh install of 12.04 as i merely upgraded 10.04 to 12.04.

Thats good news!

I did not intend to run Unity. In fact, on my dell e6500,I'm running Ubuntu Classic desktop under 12.04.

I had also the graphics problem when installing 10.04 on the d505; solved it with workaround A, if I remember correctly. Since this will now, as in your case, be an upgrade 10.04 -> 12.04, I hope everything will go smoothly with the graphics.

If, for some reasons, I would have to make a freh install I would probably chose Lubuntu or Xubuntu (PAE/NX problem...)

Any advice, as far as the WIFI (with the BCM 4309) is concerned?

I had no problems with the wifi as far as i remember

thanks for commenting!

Will most likely do the upgrade after 12.04.1 has appeared; no hurry at present.

Good to know somebody who has experience with 12.04 on the D505! Will keep you informed!
