[15:40] R. pi2 B. https://ubuntu-mate.org/download/ Check. Installation goes well - it works. After the update, the download occurs only in text mode, there are errors in the console during the update. Checked twice. [15:44] I don't think ubuntu-mate for rpi is too well maintained nowadays [15:44] I think Raspbian is a lot more optimized [15:51] I installed two times that I see - wrote. I know there are other operating systems for PI. [15:53] For 4 years now I have not used pi as a PC. This first installation in 4 years [16:43] I've been using mate in rpi2 for 2 years; then I switched to raspbian for another 2 years [16:43] mate is still my main desktop, but only on PCs [17:24] In a mate of pulsa shows sound as the output of sound one channel, I do not use sound via hdmi. I have hdmi output on dvi. The sound card in r. pi2 B has the output of jack sound as adin channel = mono? [17:25] as one channel = mono?
