After making the changes originally posted by Pedro, skip down to the Mike Lim response (I have added formatting to make it easier to read. Only use what I have posted in code below. This fix was originally suggested for an earlier kernel – but it has been superseded/replaced by the following scripts, so you will have to make some fixes for Xubuntu 13.10 (stable) or Xubuntu 14.04. Here’s a distilled version:Īdd the following to the kernel boot parameters in /etc/default/grub reload grub via update-grubĪdd_efi_memmap boot=local noresume noswap i915.modeset=1 tpm_tis.force=1 tpm_tis.interrupts=0 nmi_watchdog=panic,lapic Here is all the info you need: However, after many responses and corrections, you may find the Google+ post by Pedro Larroy a bit confusing.

As the Ubuntu kernel updates, (ie, 14.04.1) I will try to test if anything is broken – I may miss something, so let me know.If you are having problems, make sure to present them on the G+ post. I am only one person, so have a little patience – I am doing this only as a service to help you, and cannot do much in the way of troubleshooting.I am not an experienced coder – I understand the instructions below because I have scripting/coding experience, but I am presenting this only to help those who have little to no experience. ![]() I welcome help and criticism as it helps all of us with our knowledge. If they are very intimidating to you, do not take these steps and stick with crouton or ChrUbuntu! If you have anything to add, please let me know. Please remember that messing about with your system instructions can create horrible problems, for which you are responsible – no one is forcing you to make these changes. I will do my utmost to keep this updated, but keep in mind that this post is not my first priority. I am posting this guide as a point-in-time assist after the release of Ubuntu 14.04, to help those looking to fix suspend in Xubuntu on their C720s (and any Chromebook with Haswell architecture or similar hardware).
