Introduction

An 11.6-inch laptop, comes with Windows 8.1 and a hard disk. Very similar to the Acer Aspire V3 112P-P2E7, which has a faster CPU and more memory. Getting this thing to do dual-boot with UEFI is the usual pain, but doable once you've figured it out. Tested with Linux Mint 17 LTS (based on Ubuntu 14.04 LTS). Clickpad (touchpad with integrated buttons) works so-so.

Notes

Installing dual-boot

To change system boot settings, press F2 during boot. To change boot order, press F12 during boot. UEFI boot only worked with system (“BIOS”) in “Secure Boot” mode; from the system/BIOS settings, load the “EFI/Ubuntu/Shimx64.efi” key. Otherwise, I followed the UEFI dual boot instructions by Luis Alvarado, in particular:

  • Use Windows compmgmt to create free space in the partition table.
  • Disable Windows-8 fast boot (not sure that it makes a difference; just in case).
  • Disable secure boot in BIOS (otherwise, USB stick hangs after booting, without any error message). This may require that you first set a superuser password.
  • Boot from live image on USB stick (use F12 to select boot device).
  • Manually setup partitions for /, /home, swap, and start installation.
  • Reboot, go back to BIOS, re-enable secure boot (optionally disable superuser password), import EFI key from Ubuntu/Shimx64.efi. Give it a useful name (it will appear as a device in the F12 boot menu). Set the boot order such that the Linux boot loader comes first.
  • Reboot; now you get the GRUB menu with working Windows and Linux options.

Note: I installed with an encrypted home directory, but this resulted in a nonfunctional encrypted swap space, which required manual tweaking (revert to non-encrypted) to get it to work.

Tweaks

Out of the box, the screen backlight level couldn't be changed, although the corresponding Fn keys on the keyboard did generate the correct events. With the following procedure, the keys stopped working altogether, but at least, with the Gnome/MATE Brightness Applet, the screen brightness could be changed.

In /etc/default/grub, change GRUB_CMDLINE_LINUX_DEFAULT=“quiet splash” to GRUB_CMDLINE_LINUX_DEFAULT=“quiet splash acpi_backlight=vendor acpi_osi=Linux. Then run update-grub and reboot.

If you have random system freeze/hang like me. the solution is to disable the acer_wmi module (add 'blacklist acer_wmi' to /etc/modprobe.d/blacklist.conf).
If that still does not fix it. try adding pcie_aspm=off to the kernel boot parameters.

Actually this did not fix my issue. I have the Aspire V3-112P.

An addition to the outlined process:

I just installed Kubuntu 15.04 stand-alone on an Acer Aspire V3 112P-COUU. Laptop seems to be identcal to above described model.

Some hints:
You can't change the BIOS secure option unless you have a BIOS SU password defined. Then everything else is easy.

Eventually after installing, you need to go into the BIOS and manually add Ubuntu/Kubuntu as bootable OS.
