The daily builds of the new Ubuntu 14.04 are out and they are very good as well. I have installed this over my buggy and useless 13.10 installation and this is working out very well. There are no bugs and everything so far is working a treat. The Unity desktop without the ATI drivers installed is quite slow; it is slow in Virtualbox as well; but it is at least bug free at the moment. This build I am using comes with the 3.12 Linux kernel and Firefox 25.0. So this might be a good release of Ubuntu. The 13.10 release was something to forget; but this works perfectly. My Realtek USB DVB-T adapter that I wrote about before worked perfectly out of the box without needing the tip I wrote about here: http://www.securitronlinux.com/bejiitaswrath/how-i-got-my-realtek-rtl2832-dvb-t-usb-adapter-working-on-debian-7-1/. This is a very good release that could redeem the Ubuntu distribution.

I recently installed the 14.04 Xubuntu-daily and my experience with it is really smooth yet. Up to then my X220 Thinkpad ran a 13.04 Xubuntu (originally 12.04) that wasn’t upgradeable again to 13.10 by some obscure reason, so I dicided to give the 14.04 beta a try. I installed without formatting my /home-partition and it was amazing how lttle work I had to customize my installation. Nearly everything was still in place (email, favorites, even my wallpaper and my customized xfce-panels) and on top of that it’s even faster than ever. :))
