This laptop is actually a nice one (for its price at the time) and
freedom-wise the only issue is the GPU. Other than that it has a lot of

Hey, it seems to solve the problem. I was getting the same behavior once
again and I tried it. At first it seemed to do nothing (CPU was still at 100%
and all kworker processes were still up) but after a few seconds when I run
"sudo iotop" to see if kswap was there or not, it seemed to stop

That command works if you're super user (i.e. after sudo su). If you want to
use sudo with the command as one liner, you need to also use tee because
currently only echo gets run as super user but the redirect which would need

I tried with sudo, tried with sudo and "", always get the permission denied

Thanks.
So, that is supposed to be done when the problem is happening right? Or
should I do it now and it will prevent the problem from happening?
In other words, what does that do exactly? :)
Thanks in advance for the help.
It happened again and I tried what you suggested. But there were too many
modules loaded and I never got any to unload (trying sudo rmmod always gave
an error, saying that the module was being used). But I got the idea of using
iotop and noticed there was a thing called kswapd0 running. What
Actually I think it would be solved if using a newer kernel, but I have to
rely on the jxself 3.4 kernel, as it's the only way my graphics card works
properly (it's an ATI Mobility).
Thanks, I will give that a try when I get the same behavior again. It doesn't
happen everytime, and I have been trying to avoid it honestly ^_^
So this is a "suspend/hibernate/whatever" bug.
The default kernel comes with a ton of drivers. Many of these will be as
removable modules and not baked in. (And for many devices having a driver
active means they will be powered on.)
You could induce the 100% cpu condition and then lsmod to
As far as I am aware, no I don't have any other stuff running on the
background. And truth be said, I only see kworker eating my CPU,no other
processes.
I ran the command you suggested and there was no "recoll" or "recollindex" on
the list. I will try to run that again when I have the issue
I would go back to your previous link:

Yes. I think that is because my cpu only has one core... Old laptop remember?

No, I use the standard Gnome that comes with Trisquel.
Do you only have an NMI Backtrace for CPU 0? My dmesg gives an output with

additional CPU cores.

Hey guys.
I have been getting similar behavior of my machine again (not as frequently
but it happens), so I am "re opening" the issue.
I noticed it happens when the laptop is left unused for a long period of
time, when I use it again it has the kworker requesting CPU power again.

Yes, my thoughts exactly.
And apparently it solved the issues I had. So all is good now :)
That would be AHCI mode - AHCI is a modern controller language that the
computer uses to communicate with the hard drive. IDE is the legacy mode.
Sounds to me like a good option - you probably won't see a decrease in
performance, and may see a slight increase. You should be fine - if your

Well, as I was reading the comments on those page and some others, I noticed
that indeed my laptop was heating up more in the place where the disk is. So
I went to the BIOS and changed from ide to adci (or something like that). And
so far it has worked! No
According to the page:
"kworker" is a placeholder process for kernel worker threads, which perform
most of the actual processing for the kernel, especially in cases where there
are interrupts, timers, I/O, etc. These typically correspond to the vast
majority of any allocated "system" time
Well, I found this:

advice on that page but it really is a little way beyond my usual
understanding of linux systems. :(
Hey guys, thanks for all the replies.
Well, turns out I was only seeing my own processes.
After a little testing, what I see is that a process called "kworker/0:0",
"kworker/0:3" and "kworker/0:4" consumes a lot of CPU power, basically doing
nothing.
Xorg also appeared but it takes nothing

What's your CPU speed? You can check it in settings>about. I own an old Dell
laptop (from around 2007) and it runs GNOME Shell. This uses about 25-50% of
the CPU already, and running the package manager (updater uses the apt
process) can be quite intensive when picking lots of packages.
Do you see all processus on your computer or just only your processus ?
Lately my laptop has been overheating, to the point where I had to lift it up
with some books on the sides, so that there is better air circulation.
When trying to see what could causing it, I noticed that the system monitor

Hello,
I currently have a Libreboot T400 running Trisquel 7.0 Belenos, with the
GNOME desktop environment. Starting just yesterday, I noticed that whenever I
suspend my system, the laptop restarts after I try to wake it up. I've made
sure that all of my packages are updated, and it wasn't

Ok, let's try toggling that.gsettings set

I did that, and after I hit space bar it briefly came back on, then it just
shut off.

I managed to do "everythingtypically needed" on a crappy atom with 1 gb of

It ultimately depends on what you need to do. If you don't need hardware
acceleration for graphics (which 3-D games, modern desktop environments, and
tools related to working with 3-D will run more slowly without), most of them
will basically work. However, it's highly unlikely that WiFi
i recently got a laptop from a online auction website for £25

I second this. Buying second-hand is a good way to NOT give Microsoft your
money.
I don't think they offer laptops but here is a relatively new Portuguese

Thanks.
Just for understanding..
As I will use only Free and Open Source Software, I have two questions
1) I'will have problem regarding non-free drivers or binary blob?
2) Will FOOS prevent me from loading or using binary data loaded in BIOS or
in the CARD ?
Thanks for you patience
The BIOS is out of the scope of the operating system. Trisquel, more
precisely its kernel (Linux-libre), does not contain any blob. I do not know
about you specific model but nVidia cards are not as bas as AMD's: it should
work fine and you will probably even get some 3D acceleration.
Their is today more or less impossible to get a MBP 15 inch laptop
replacement. All other laptops have 16x9 screen and a numpad that moves the
keyboard and mousepad so it isnt in line with the screen. And other laptop
developers wonder why people like Apples hardware.
Nvidia cards do work better but that's no thanks to nvidia but instead a 3rd
party reverse engineering effort to produce nouveau, a free driver and
firmware.
Also, intel cards will not work if they are powervr based.
yes. I really wonder why people keep buying extremely overpriced hardware

I think It can sometimes take a long time to wake up from standby. Try
standing by, and then wait when waking up, and see whether the computer
finally wakes up after, say, a few minutes.
Anyway, I think there's a seting that disables standby, only enabling screen
turn-offs instead.

No, it should also disable the problematic Nouveau driver, that may cause

Nope, just don't forget to add the acpi_osi= parameter to GRUB either with

you battery power). You will be then able to switch the default
