The updates of September 21 fixed my issues. Only after I bought a new motherboard to fix it.

Sometimes I can log in using ssh from another computer, do a shutdown -r, but that then hangs also. What I've experienced in the last hour is that the computer slowed down and stopped, I had an ssh shell window open on another cocmputer, showing "top". I noticed Xorg took up to 17% of CPU, later up to 26%. I had Eclipse open, and Android Studio, both frozen. From the other computer I stopped Eclipse, AS still frozen. Half an hour later, AS unfroze. Xorg still 16% cpu. I used ubuntu-bug from the shell window, but somehow it didn't get through in Lynx. Right now, the computer mostly unfroze. I have experienced Chrome freezes. There's a bug registered for that, I'll add info after I hit enter, before this computer freezes again. I have replaced graphics card (same model), motherboard, cpu, memory. Orderd new power supply and new model graphics card. Also, I have issues typing the disk decription password, there's a bug report for that.
