yesterday I installed Ubuntu alongside Windows 10 on my HP pavilion x360
I followed Ubuntu 14.10 Startup & Shutdown Issues w/ HP Pavilion x360 and solved my shutdown/restart issue
I tried this No wireless connection on HP Pavilion x360 Convertible to solve my wifi issue, but it didn't work (I still can't access wifi)
This morning come a new issue far more problematic : I can't access my grub anymore.
When I boot this morning, I chose windows because I have no connection on Ubuntu (I had the grub at that time), later, I tried to reboot on ubuntu : and my grub is gone, I have absolutely no way of starting Ubuntu.
I've seen a few things in the comments here https://www.linux.com/community/blogs/130-distributions/839692-dual-boot-ubuntu-15041410-and-windows-10818-step-by-step-tutorial-with-screenshots
but nothing worked for me so far
I suppose windows have done something but can't figure out what
I've got a HP pavillion x360 11k001nl. I managed to prepare a usb live key with ubuntu 14.04 64bit which does everything but recognizing the partitions (ubuntu installer says that the partitions are "hidden" and sees only that of the usb key I don't know how to make them visible as well as usable by ubuntu installer). Anyway I followed this advice:
to activate wifi negli x360
from terminal:
sudo tee /etc/modprobe.d/iwlwifi-opt.conf <<< "11n_disable=1"
Then reboot.
to remove the block of the shutdown of the system from terminal as root (of course):
echo "blacklist dw_dmac" | sudo tee -a /etc/modprobe.d/blacklist.conf
echo "blacklist dw_dmac_core" | sudo tee -a /etc/modprobe.d/blacklist.conf
If Acer
rfkill list all
I don't run Ubuntu (Fedora) but had the same problem (wifi not switching on) on an HP PAV x360 and also had the same symptoms, namely:
1: acer-wireless: Wireless LAN
Soft blocked: yes
You need to blacklist the acer_wmi module (it never should have been loaded!)
lsmod | grep acer
Edit (or create if it doesn't exist) /etc/modprobe.d/blacklist.conf
Add the following lines
# Disable acer_wmi as it breaks wifi on this model
blacklist acer_wmi
Now unload the module (it will be blacklisted on the next boot so you only need to unload once)
modprobe -r acer_wmi
Enjoy your working wifi!
