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.
