This looks like your physical RAM is getting full and the system starts to use the Swap. Programmes like Chrome can take easily take up several Gb of RAM. On 12.04, with about 20 tabs open Chromium would get to 2 Gb of RAM in less than a day. You can start by monitoring closely your free RAM with the System Monitor. See if these episodes of high disk usage ...

My first guess would be graphics, which installing something like Xfce or Lxde would help with. However you really need to provide more info

Change your viewer from EOG to GPICVIEW . I had the same problem. Large images (3000x3000, roughly 3-5M on a RAM set of over a gig), causing total desktop lockup (requiring shutdown and restart). I thought RAM was going bad so I did memtest and no. I thought my drive might be bad so I did Disk Utility check and no. I hope this helps.

It turned out to be a hardware problem - graphic card fan was packed with dust, and graphic-costly operations (like watching videos) caused it to overheat. I found that out when it was already too late and I needed to replace the graphic card.

Your video card drivers version should be 340.46. I am sure you can open nviida-settings and check out version, and also adjust all related power-management fields in nvidia-settings. In Kubuntu default power management, make sure you check your settings for all of the 3 sections present in there, namely AC POWER, ON BATTERY, ON LOW BATTERY. Disable Dim ...

Since I upgraded to 14.04 Skype and VLC among others have not worked properly for me too. VLC video was not appearing, and I managed to fix it by changing the output (it is in the preferences). For Skype: I have read different posts online, most of them suggest it is an issue with Open GL or the graphic card. I still have not managed to solve it but a ...

This ended up being a driver issue. The solution would likely have been to install the NVIDIA driver from System 76's PPA, but the machine has since been reimaged.

It's normal that you would not see much, if any, swap usage unless you are using an app that really needs a lot of RAM, so I wouldn't worry about that. However, the fact that your home directory is a symbolic link to a different drive might be a problem; is there a reason for that? Normally, you would mount the home directory, not link to it. It would ...

According to your dmesg output there's a bug in the WiFi driver. Let's take a closer look: the most recent wakeup event is at [22500.127146] ACPI: Waking up from system sleep state S3 and the wakeup finishes ~5 s later: [22505.833530] PM: Finishing wakeup. The system then takes another ~5s to re-initiate the PS/2 interface (for keyboard and touch ...

As suggested by @Sia i looked for a proper driver. In the end, installing the Intel Tool for this job solved the issue.

So, after some discussions in the comments we found it's a problem in the wifi driver. The right way is to file a bug in the linux kernel bug tracker, or Ubuntu Kernel Team Bug Tracker. Since you seems like a developer who make things as strait as possible, you can try to find the bug and fix it yourself - get the kernel source using git, fix the bug in the ...

I had a similar issue with a desktop, while using two monitors and working with paraview, that one was solved with installing the right driver for the graphic card. Though there is a little chance that this be your problem since xps is fully supported by ubuntu as far as I know, but take a look in your drivers see if there is any other possibility available ...
