Not quite what I was expecting from Linux, but still, I think we are getting there. I got notice of an opportunity to upgrade to 16.04 from 14.04 as I was installing updates to 14.04. I waited for the updates to install and then started on the upgrade. My opinion with Linux is that it seems to be better to do a clean install from an iso than upgrade an existing version. It takes AGES. Two hours later I had the upgrade installed. It had stalled when it was installing fonts and appeared to be quite dead. I left it for 15 minutes and it righted itself thank goodness. It was then very glitchy as it got going. The laptop would hang and then get going again and I was thinking I had not made a good decision. This is a Dell Studio 1558 i7 cpu Q740 1.73 GHz with 6 GB RAM. I can see where the problems are. Ubuntu 16.04 is probably built for something a bit faster. Graphics have been an issue. I can’t use Shutter because it hangs the computer. I use the print screen button and then crop the picture which takes longer but at least I am not stalling my computer. I had Kaffeine running TV from a DVT stick and then it fell apart but, as you can see from the picture it was working fine again this morning. Speaking of which, when I rebooted this morning I had a lovely black screen with a colourful stripey rectangle to the right. Nice modern art but not an operating system. I shut it down, waited for a minute and then turned it back on. A magenta screen with a choice of 3 options. Oh good. Choices but none seemed to mean anything to me so I selected the one highlighted. Linux instinctively chooses the right option in my experience. So now my laptop has been running all morning. I have done any number of different things on it and have been to all sorts of different sites and used different applications. I still cannot use Shutter. Everything loads quickly, everything looks really nice. The graphics on this are well designed. I shall wait until the next version of 16.04 because I can say one thing for the Net, everyone gets on there and says what problems they are having. Coders and developers then have a way of fixing things which are going wrong and getting good information out. I have installed the updates. It appears to me running more smoothly and I am following what I have not already done on 16 things to do after installing Ubuntu 16.04. This sort of advice is very helpful. This version is running better on my Dell than 14.04 so I am hopeful the silly nonsense will be resolved. I hate living with the feeling I shall jam up the works just because I want to cut and paste!
