I have two computers, a desktop and a laptop. Both are now "Ubuntu 12.04" computers.
The laptop I kept on a 6-month release cycle. When I installed Ubuntu 11.10, because I also help maintain a number of non-techie friends' Ubuntu computers, with the demise of GNOME 2 I started investigating other desktop environments, in help them with the transition. Among these was Kubuntu-desktop, which I liked so much that I eventually switched to Kubuntu for daily use (though I changed the boot splash back to Ubuntu, as I preferred that splash screen, and I still have and keep Unity, GNOME 3/GNOME classic, and Enlightenment on my systems either for specific purposes or to keep handy in case something breaks in one Desktop environment as I can go in and fix it in another). I enabled the Kubuntu backports to keep abreast of the latest releases of KDE (it's now up to KDE 4.8.5.
My desktop computer was on Ubuntu 10.04 until I upgraded a little more than two weeks ago, with the release of Ubuntu 12.04.1. I searched for Kubuntu-desktop in the repositories, and did not find it. I did find the metapackage "kde-standard" and installed that, thinking that since Canonical was no longer supporting Kubuntu after the 12.04 release, it perhaps did not want to encourage its use. (Later I did find out that kubuntu-desktop *was* still in the repositories; one had to "show technical items" to find it).
I caught on that there was a difference between the two metapackages when I found out that:
1) Installing kde-standard didn't change my boot splash screen on my desktop (it had on the laptop)
2) When trying to customize the application look and feel for GNOME (or at least non-KDE) applications I couldn't get them to look the same. Here are some screenshots (with pretty much identical settings):
a) Evolution (desktop first, Laptop second)
b) Firefox (desktop first, laptop second)
BTW, I have both gtk3-oxygen-engines and gtk2-oxygen-engines on both computers.
3) The Twokinds comic I used in Kubuntu broke earlier this year and wasn't fixed. In KDE-standard it works (I fixed in in the Kubuntu version by copying and pasting the relevant .desktop files into the /user/.kde/ subfolders).
4) When I enabled the backports in the desktop (originally with KDE 4.8.4), I got KDE 4.9 (!) instead of the KDE 4.8.5 which is the latest for Kubuntu.
Now that I have found the kubuntu-desktop in the "show technical items" in the repositories, I am wondering if it would be OK to install that customization. I am hesitant, because:
a) For some GNOME apps like Evolution and Rhythmbox, kde-desktop actually faithfully preserves the GNOME 3 look. My Kubuntu laptop does not (I've gotten it so I think it looks pretty, but it's not faithful);
b) More importantly, now that I'm on KDE 4.9 by enabling the backports on my desktop, but only on 4.8.5 by doing the same on my laptop, would downloading and installing kubuntu-desktop break something? (I figured that if kubuntu-desktop was ready for 4.9, it would already be in the backports).
Replies and input appreciated.
