Laptop freezing -- figuring out the issues

Hi all, I have an awesome laptop I bought from my son, a hardcore gamer. So used, but also very beefy and well-cared-for. Lately, however, it has begun to freeze, by which I mean: the screen is not updated, and no keyboard inputs are accepted. So I can't even REISUB; the only cure is the power button.

I like to leave my laptop running overnight for a few reasons -- to get IRC posts while I sleep, to serve *ubuntu ISO torrents, and to run Folding@Home.

Attempting to cure the freezing, I've updated my graphics driver, rolled back to an older kernel, removed my beloved Folding@Home application, turned on the fan overnight, all to no avail. After adding lm-sensors and such, it didn't seem likely to be overheating, but I'd like to be sure about that.

Lately I turned off screen dimming at night and left a konsole window on the desktop running `top`. This morning I found a freeze again, with nothing apparent in the top readout:


So I went looking on the internet and found this super post: Using KSysGuard: System monitor tool for KDE. The first problem was that when I hit Control+Escape, I could not see the System Load tab he mentioned or any way to create a custom tab. However, when I started Ksysguard from the commandline, it matches the screenshots in the blog.

Here is my custom tab:


So tonight I'll leave that on my screen along with konsole running `top` and see if there is any more useful information.

Folding, origami, and Folding@Home

A few months ago, I started Folding@Home in the Ubuntu Folding team. I really enjoy checking my standings each night before I go to bed. What is Folding@Home? https://folding.stanford.edu/home/about-us/. Has Folding at Home actually done anything useful? Check Reddit and see what you think.

Team 45104 Rankings. http://wiki.ubuntu.com/FoldingAtHomeTeamUbuntu if you are interested in competing while contributing. It seems like interest has fallen off in the past year or so, which is a bit sad. On the other hand, it makes climbing up the standings easier!

I was reminded to make this post while watching NOVA tonight on PBS, about Origami. There are so many new applications to this ancient art of folding paper in art, in mathematics, physics and material science, and even biology. You can see it online if PBS is not available to you.

PS: right now, I have 921,667 points, which puts me in the top 180 in TeamUbuntu (#179 to be precise).

Google Code-in draws to a close -- students finish your final task by January 16, 2017 at 09:00 (PST)

KDE's Google Code-in party is ending once again. Student work submitted deadline is January 16, 2017 at 09:00 (PST). 

Mentors, you have until January 18, 2017 at 09:00 (PST) to evaluate your student's work. Please get that done before the deadline, so that admins don't have to judge the student work.

Then it will be time to choose winners. We need to have our choices in by January 23, 2017 at 09:00 (PST). Winners and Finalists will be announced January 30, 2017 at 09:00 (PST).

To me, this contest has been lovely. Because there are more organizations participating now, there are more tasks for students, and less pressure on each org. It seems that the students have enjoyed themselves as well.

Spencerb said, in #kde-soc, This was my first (and final) gci, so I don't have much of a point of comparison, but it's been awesome. I've been an opportunity to meet new people and just get involved with KDE, which I've wanted to do for a long time. I've also learned a lot about serious software development that I wouldn't have otherwise.

"I'll turn 18 this Monday, which is why this is my last year :(  I'm so glad to have had the chance to participate at least once.

As a task, Harpreet filed a GCi review: http://aboutgci2016.blogspot.in/

So far, we've had 121 students. The top ten have 103 completed tasks so far! And 160 tasks completed so far. Most exciting for me is that Beginner tasks completed: 45. Getting kids acquainted with Free and Open Source Software communities, which is why every organization must have beginner tasks. I'm glad 45 kids got to know KDE a bit.
