A last resort, when something within your home directory has been messed up, but you don't know what the problem is, is to rename it and create a brand new home directory. Assuming that your username is moss, running these commands from a TTY would do it: cd /home sudo mv moss moss.old sudo mkdir moss sudo cp -rT /etc/skel/ moss sudo chown -R moss:moss ...

I finally got success to install Lubuntu: I started the installation with the options: acpi = off / noapic / nomodeset. Installed lubuntu normally, and the OS worked like a charm, subsequently I updated the video driver (NVIDIA). I hope this serve someone who is having the same problem. Thank you!

No, it is probably not because you are loading a 32 bit OS on a 64 bit computer, but when I first installed Ubuntu It kept freezing because the graphics card couldn't support Unity. But lubuntu should run even on computer of those specs. Try creating an install CD instead of a bootable USB, and check to see if the ISO is corrupted verifying its data ...

I will answer my own question, maybe it will help somebody in the future. After many trial and error, it seems that disabling VT-x option in UEFI options seem to solved the freezing. So far running a few days without problems.

Updating the kernel worked for me. I suspect the issue was graphics related because I noticed a warning during the upgrade. I followed the steps at http://sourcedigit.com/19889-how-to-update-install-linux-kernel-4-7-rc3-on-ubuntu-16-04/ to upgrade the kernel then downloaded the missing firmware. Full steps detailed below. Download the necessary files: wget ...

It seems the issue was with the hardware membrane for the T key. I popped out the key, tried pushing the membrane hard (Ubuntu froze and got a black screen), tried lifting the membrane up a little, cleaned it. Since then, I didn't get any issues so far. It seems, moving the membrane a little bit did the trick.

Well there is a magic key combination (to reboot): While holding Alt and the SysReq (Print Screen) keys, type REISUB For more details visit this answer : http://askubuntu.com/a/36717/497359

Switch to the console: CTRL + ALT + F1 After login, you can see which processes are running using this command: ps -ef If you see a process which has high CPU usage, you can kill it. sudo kill <pid> Of course, you can simply restart the PC too: sudo reboot

I had the same problem on my XPS12. In case it's useful, /var/log/kern.log said: Jun 3 13:53:49 oli-xps12 kernel: [23462.982691] i2c_hid i2c-DLL05E3:01: failed to reset device.

As far as I can tell your laptop has Intel Skylake integrated graphics. This (as well as the previous generation Broadwell graphics) is currently the subject of one or more widely reported issues that cause laptops to freeze, particularly when plugged in to external monitors :-( These issues have been reported on both 14.04 and 16.04. At present the only ...

Try if you can Ctrl+Alt+F1 and back with Ctrl+Alt+F7. Sounds a little like a NVidia issue I have with an Optimus chip and properitary drivers. For me this was working until the next freeze. I'm using the open source driver since then as my laptop is not used for gaming. Please post more of your specs. Update your post.

I had the same issue with Ubuntu 16.04 on my laptop. My laptop was a Dell E6420 with an nVidia video card. The issue was related to the nVidia 'open source' driver not working correctly. I pressed Ctrl+alt+F1 at the logon screen to drop to the terminal and used command line to load the proprietary nVidia driver. Working great ever since. How to Install ...

When you say "Keyboard shortcuts don't work either", does that include Ctrl-Alt-F1, to open tty1? Instead of the reboot button, you can reboot in a more controlled manner by holding Alt+SysRq and typing REISUB slowly. This will dismount the file systems normally and prevent corruption.

Open up a terminal. $ sudo su $ cat /var/log/syslog Anything unusual there? Scroll upwards to the point where it froze, notice anything there?
