Asus Zenbook Prime UX21A issues

[fab.head]

Fix for (most) Fn-Keys:
I took this patch and made my first DKMS package (maybe sloppy, but works for me):
http://comments.gmane.org/gmane.linux.kernel/1315719

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

Just install this package using following code:

gzip -d asus-wmi-dkms_999.01_all.deb.gz
sudo dpkg -i asus-wmi-dkms_999.01_all.deb

xev does now recognize Fn keystrokes

Thanks nexero,

Is this patch just for UX21A or also for UX31A?

I've installed it on a UX31A (and even rebooted it) but nothing has changed.

Mmh... it 'should' work for both, as it just changes the way asus-wmi kernel module handles the DSTS table...

could you post the output of the following command?

dmesg | grep asus

[fab.head]

Here it is:

dmesg | grep asus
[ 1.908236] asus_wmi: ASUS WMI generic driver loaded

New module has not been loaded... should look like this:

please reinstall, using the same command and post the complete output here..
maybe you don't have DKMS installed yet?

sudo apt-get install dkms

Hmmm, while reinstalling I've noticed the following error message:

This dkms-package uses the header-file asus-wmi.h from linux-source-3.2.0... It will work with the shipped kernels of Ubuntu 12.04!
rfkill.h changed in linux 3.4.0, therefore it doesn't work...

[fab.head]

I see.

Unfortunately I had to switch to 3.4 (got it here, plus xserver-xorg-input-synaptics from quantal) to get the touchpad fully supported.

Thanks anyway

Hey there!

I got my UX21A three days ago and there are some issues, using Ubuntu 12.04...
Since, there are reports of similar (if not the same) issues on UX31A, this thread should address these two models...

Issues:
* some Fn-Keys do not work
* keyboard-backlight won't turn off
* Power-Key doesn't show Power-Menu.. it does nothing instead, when pressed..
(* wifi disconnects often (but signal is very good!), latency is sometimes very high (up to 1000ms, but only on 802.11a - 5GHz)) -- might be just an issue for me...
* brightness sensor (does ubuntu already handle those kind of data?)
* keyboard-backlight turns off after closing lid and go to standby
* standby doesn't always work when closing lid (then you have to use the Suspend-Fn-Key...)
* power saving is not quite perfect, I only get about 5,5~6h of battery life (using same tweaks as for UX21E)
* there are random freezes, once or twice a day, using latest (and earlier) shipped kernel of Ubuntu 12.04 (linux 3.2.0-26), this issue is not present in Kernel 3.4 and higher (using mainline kernel 3.4.0, but power consuption is ~1W higher (equals 30 minutes!) with this kernel)
* webcam
* incl. USB-LAN-Adapter

Not tested yet:
* suspend do disk
* Micro-HDMI
* incl. VGA-Adapter


Now, do you have any idea, how to bring these Fn-Keys to life?

Kind regards

Hi,
I'm looking forward to buy the new zenbook ux21a, I saw that the ux31a model is available on the US Amazon site, could you tell me where did you find the ux21a model ?
Thanks

Sry, I can't help you, I live in Germany.

Regarding my freezes (don't you experience them too?!):

http://forums.linuxmint.com/viewtopi...f=191&t=102158

I just installed 3.4 from Debian testing. So far nothing changed, but maybe the freezes do not happen anymore. We'll see

I used linux-image-3.2.0-0.bpo.2-amd64 from Debian's squeeze-backports before (which is a 3.2.18-1 I think).
