Comment 6 for bug 1597792

Adding to my comment. My upgrade has been a mini-disaster. First, the upgrade from 14.04 repeatedly failed. So, I just did a fresh install. This was not too bad, because I had previously formatted my drive to keep home directories separate. I also had an external backup.

Finally, I also used aptik to help install software. That worked partially, and mitigated the pain, somewhat.

However, now audio works only sporadically, and requires that I do an "alsa force-reload" on a regular basis to get it to work. I often have to go to system settings to reset everything. Sometimes that reset isn't saved, and it still does not work. Given that the problem is sporadic, I am hesitant to ask for help, because that would require lots of homework on my end, which I don't really have the time for right now.

Possibly related to this is that squeezesoft sometimes starts eating up tons of resources, and I have to restart the service.

I also have your problem of plasma eating up lots of CPU and everything is often slow. Sometimes the whole screen just freezes for about 20 seconds, and I have to wait for even typing to catch up. I have tried some of the solutions on the web, but that hasn't worked. I built this particular desktop to be friendly with linux. Since this is a fresh install, the problems out of the starting box are particularly disappointing.

I hate microsoft windows, and don't want to enter the closed ecosystem of apple. But, linux requires this constant sort of maintenance, that I often need to avoid. Fortunately, this desktop is my sort of test case for such upgrades, and it did not really pass. I have already spent way too much time trying to get things working. I will avoid updating my other machines to 16.04, and only update when the support on 14.04 runs out. Not sure what I will do then, but certainly try to find some version that focuses more on stability. Maybe Mint?
