Issues on ASUS X550LC (after installing ubuntu)

Question

I've installed ubuntu 14.04 on my ASUS X550LC. Here I've found some issue:

Bluetooth is not working.
Brightness is going 100% after every reboot.
Brightness and network controlling shortcut key is not working.
Network LED (which should be green when connected with internet) is not working.

To solve brightness issue I have tried first and second solution from this question, but that does not worked.

To solve bluetooth, I have tried Blueman from Software center, but that does not worked.

how is bluetooth not working? Does the bt indicator show up in the title bar? Do you have a bluetooth mouse showing up in the battery indicator? I do have problems from the battery indicator -- mouse works until it shows up. — ubfan1, Oct 02 '14 at 05:53
No, bluetooth indicator isn't showing in the title bar. And when I turn bluetooth on from System settings>Bluetooth and hit the button (on/off) it shows bluetooth is on. But nothing happened. ANd I can't use any other option like Visibility(ON/OFF) and +/- option (that is for connecting or adding new devices). — opu 웃, Oct 02 '14 at 06:06
Please open a terminal with Ctrl+Alt+t and paste your lsusb output by editing your question. — P.-H. Lin, Oct 02 '14 at 07:17
Hmmm... maybe you Bluetooth is connected to the PCI bus, could you please update it with lspci -nn? — P.-H. Lin, Oct 02 '14 at 07:35
You Bluetooth is Ralink RT3290 [1814:3298], which is not supported, see Ralink RT 3290 Bluetooth Problem on Ubuntu 14.04 for more information. — P.-H. Lin, Oct 02 '14 at 08:06
@ P.-H. Lin, thanks a lot. Now bluetooth icon is appeared in the indicator. But it is still not working :( — opu 웃, Oct 02 '14 at 08:37
Have you tried booting Ubuntu Utopic Unicorn Beta live to see if that fixes your problems? If so, you should wait a week or two for Utopic. I know it fixes a lot of hardware bugs. And I mean a lot. It's like the main focus of the release, rather than getting new features. For this reason, many people are calling Utopic "the boring release". — John Scott, Oct 09 '14 at 01:46

For the brightness issue please do the following.

sudo gedit /etc/default/grub

find the line that has "GRUB_CMDLINE_LINUX_DEFAULT" and change it as following

GRUB_CMDLINE_LINUX_DEFAULT="quiet splash acpi_osi="

save and close gedit then issue the following command into the terminal

sudo update-grub
