Mouse/Ubuntu seems to freeze up every few minutes?

[PsychedelicWonders]

It's a new clean install of 14.04 on an SSD and every few minutes the mouse/Ubuntu seems to freeze up for a minute or so and then goes back to being ok for a few minutes then the mouse freezes again etc. This is a wireless and wired mouse.

Any ideas on the issue so it can be fixed?

I take it that the wireless is USB dongle, but both tried on the same port? If so, try changing the USB port. Also, look at dmesg output for clues/conflicts.

[PsychedelicWonders]

Still having this issue and it happens every couple of minutes - beyond frustrating!

Yes it is hooked up via a dongle, I am new to Ubuntu, so where do I find this dmesg output info?

[tgalati4]

Open a terminal:

dmesg | more

Spacebar to page forward, "q" to quit.

Paste any error messages, not the entire output.

[PsychedelicWonders]

Hmm, I ran that code and didn't seem to see any error messages.

Now that I've been using it a bit more, it seems that it's actually Ubuntu freezing up for 10+ seconds, then goes back to normal.

It did this on the install just before this one too. I installed a fresh 14.2 Ubuntu on a brand new SSD and forgot encryption password so had to secure erase and then reinstall. This lag/freeze issue happened on both installs.

Any other idea on what it could be or how to fix it? I can't use Ubuntu if this persists...

I had freezes like that until in the Mouse & Touchpad settings I deselected al the Touchpad options (there are 4) but don't disable touchpad itself.

Haven't had a freeze since.

[tgalati4]

If the Mouse and Touchpad settings don't fix the problem, I would look at encryption. What is encrypted? Your home folder? The entire operating system? It's possible that encryption is causing the delays.

Install htop. Open a terminal:

sudo apt-get install htop
htop

Describe what you see during the frozen periods.

[PsychedelicWonders]

Yes I have the entire OS & home folder encrypted. I figured if it gave me the options, I might as well utilize them.

I do plan on defaulting to the SSD hardware encryption that Samsung uses once I get an Asrock Mobo (they are the only mobo that will allow a bios setting to set a TRUE ATA password to enable the encryption of the key to the encryption.) But for now I figured I'd use the software encryption Ubuntu comes with.

That is unless that is what is causing these delays/timeouts.

It's hard to say, but I think it's the entire OS freezing. I will install and run that htop now and post my results.

[PsychedelicWonders]

Ok so what should I post back from the htop program?

It is def the entire OS freezing up. This is a brand new Samsung 850 Pro, shouldn't be any issues being able to handle Ubuntu's encryption. I really hope that's now what is causing this lag, I think it's a great feature being offered on the OS and I would really like to use it, but not if it comes down to this constant lag/freezing.

[tgalati4]

I'm sorry, you only need to run top (which should already be installed.) Pay attention to CPU load, IO Waits (wa) and System load (sy). I believe encryption should be captured by the System load cycles.

It might look something like:

tgalati4@Mint17 ~/Desktop $ top

top - 20:17:30 up 2:53, 2 users, load average: 0.81, 0.62, 0.48
Tasks: 184 total, 2 running, 182 sleeping, 0 stopped, 0 zombie
%Cpu(s): 1.8 us, 1.5 sy, 0.0 ni, 94.9 id, 1.8 wa, 0.0 hi, 0.0 si, 0.0 st
KiB Mem: 2040640 total, 1961564 used, 79076 free, 1760 buffers
KiB Swap: 2578428 total, 74284 used, 2504144 free. 387200 cached Mem

Hit Control-C to quit, then you can cut and paste the results. Try to do it before and during a freeze.
