Problem is I am now booting to the terminal! If I connect an external monitor the GUI immediately kicks in. But after a reboot/shutdown its back to the terminal.

I tried replacing "quiet splash acpi_osi=" with “nomodeset” but that didn't fix it.

The only way I can boot to X is via selecting "Advanced options for Ubuntu" in the grub menu and booting kernel 3.5.0-21

Any suggestions?

First, you need to give more details on your system.
Boot into a working kernel and open a terminal:

Code:

uname -a && cat /etc/*release && sudo dmidecode -s system-product-name

Since ubuntu 12.10 uses a kernel 3.6, I guess you didn't read the warning regarding ubuntu 12.04:

Note: This only works for Ubuntu 12.10 (aka. Quantal Quetzal), not 12.04!

Strangely I am booting into X fine now. Not sure what fixed it.

The output you requested:

Linux charlie-UX31A 3.7.2-030702-generic #201301111424 SMP Fri Jan 11 19:25:11 UTC 2013 x86_64 x86_64 x86_64 GNU/Linux

There's a "=" missing in after "acpi_osi", should look like this

The Ubuntu ZenBookPrime page (https://help.ubuntu.com/community/AsusZenbookPrime) says the fan control is "fine" but I've found in ubuntu 12.04 the fan behavior seems very erratic. It will often go to full blast and then shut completely off for no apparent reason, or run on full when there is no real load and the thing hardly feels warm at all. I'm finding it fairly irritating but it doesn't seem like anyone else is having this problem.

Same behaviour on mine. I find that the fan runs full blast for about 5 secs and then completeley stops for about 2 secs and then runs again for 5 secs etc etc when in use.

If I am stop using it for a 1 minute the fan stops but a tiny mouse movement is all it takes to start the cycle starts again.

What BIOS version do you have?

Code:

sudo dmidecode -s bios-version

You can get updates here as described in the wiki...

My version is UX21A.216 and it's running fine...
Also changelog of 216 does state of "abnormal behavior", so you may try an update:

BIOS 216
1．Fix that the fan PWM is abnormal randomly
2．Fix that the system will enter BIOS setup menu sometimes
3．Update microcode for IvyBridge
4．Update Intel ME Firmware
5．Update EC FW

Most Fn keys are working now, except for Fn-F5 and Fn-F6 (changing LCD brightness)

Just install this package using following code:

Code:

gzip -d asus-wmi-dkms_999.01_all.deb.gz
sudo apt-get install dkms
sudo dpkg -i asus-wmi-dkms_999.01_all.deb

xev does now recognize Fn keystrokes

I confirm that now my fn+f11/f12 key is actually working after the code upon here written.
Thanx

Hello, does everything else work with BIOS 216? I read on arch linux forums, that with BIOS 216 there are new problems introduced with the battery, it doesn't get powered anymore to 100%, but gets stuck at about 70%. Or something is wrong with the power status. Can you confirm those problems with BIOS 216?
