Linux Compatibility

Optical DriveYes
Sound 1. With alsa =<1.0.17. Partial, use options snd-hda-intel model=3stack-dig (edit file /etc/modprobe.d/alsa-base). Inserting headphones doesn't mute speakers. Sound over hdmi doesnt work.
2. With alsa >=1.0.18a. Fedora 10 and Ubuntu 8.10 sound is fine. Option “snd-hda-intel model=3stack-dig” need to be removed. For easy installation, you can use Linuxant
56K ModemNot Tested
Card ReaderTested for Memory Stick Duo Pro card - not work; SD cards seem to work with sdhci module
ExpressCard SlotYes. See note
Fingerprint ReaderYes

Light sensor

The ASUS m50vn notebook is equiped with an automatic light sensor,
this sensor must adapte the screen brightness according to the ambient light.
Under Linux the results is somehow not suitable, nevertheless it is possible to switch
the sensor off, in Fedora linux this can be done using a script:

# chkconfig: 2345 20 90
# description: Startup script for to stop/start
# the automatic brightness sensor on ASUS notebooks


echo -n $”Starting the automatic brightness sensor“
echo 1 > /sys/devices/platform/asus-laptop/ls_switch
touch /sys/devices/platform/asus-laptop/ls_switch
echo ”“
return $RETVAL

echo -n $”Stopping the automatic brightness sensor“
echo 0 > /sys/devices/platform/asus-laptop/ls_switch
touch /sys/devices/platform/asus-laptop/ls_switch
echo ”“
return $RETVAL


case “$1” in
status brightness
echo $”Usage: $0 {start|stop|status|restart}“

exit $RETVAL

Lets call the script brightness and lets put it in /etc/init.d and use chkconfig to configure it as a service:

su -
cp brightness /etc/init.d
cd /etc/init.d
chmod 755 brightness
chkconfig –add brightness
chkconfig –level 2345 brightness on

graphical start-up

It is possible to improve the start-up of the computer (on a graphical point of view)
by adding the following instruction to the kernel loading line in the /boot/grub/grub.conf file:

kernel /vmlinuz ……………….. vga=0x361


Tested on AVerTV Hybryd Express Slim - Requires a reboot, the device was defined.

04:00.0 Multimedia video controller: Conexant Systems, Inc. CX23885 PCI Video and Audio Decoder (rev 02)

The system has identified the device, but the tuner is not supported, therefore, fully test the slot is not possible :(

Made a review under Arch Linux :

Why the heck are you using such an old distro ?
Use something newer, everything is 100% fine since kernel 2.6.35 after a period of video crashes between 2.6.30 and 2.6.34.

I'm using 9.10 because I'm working on a project that needs it, because of some compatibility problems between Tomcat and Ubuntu 10.10, it's the only way to let the web project work locally.

Anyway when I tried with the last Ubuntu (10.10) I had the same problems.

Potty DJ, 2010/12/07 01:41

About the audio driver, please note that with:

Alsa 1.0.23
Ubuntu 9.10 Karmic

I installed the Linuxant drivers, but I also had to ADD (not to REMOVE like said in the article) model=3stack-dig to the alsa-base conf file, in order to let the speakers finally work.

About the keyboard, I searched for a way to let some key shortcuts work, like for example “SHIFT+END” in a text. Actually they don't work because the END button is in the numpad and maybe the driver is mapped badly; but for me this is an important feature, in order to manipulate texts or code faster. I ran into this solution:

open menu System/Preferences/Keyboard, choose a Generic 105 Keys (Intl) PC Keyboard, then open the “disposition options” dialog and under “Various compatibility options” check the option “Maiusc plus the numpad keys act like in MS Windows” and save, it's done!

I have n50vn, OS OpenSuse 11.1 and Ubuntu 9.04. WIMax don't working.
Please help

Works pretty well under Arch Linux, out of the box. :)

CPU, HD, sound, wifi, card slot, usb, VGA, CDVD burner, ethernet works fine.
The special (Fn + F2, F3, F4, F9, F10, F11, F12 and the four buttons) aren't seen by the system. (tried xev)
Not a very huge problem :)

But the sound still donesn't mute plugging headphones.

I don't need the 56k modem but I tryed to find it ; lspci gives nothing and minicom doesn't find it on ttyS0, …, ttyS3.

Perhaps it's a winmodem.

I recently bought an ASUS M50Vn (model made specifically for MediaMarkt in Germany, identical to the standard M50Vn except for the CPU = P8400/2.26GHz). It basically works great except for fiddling needed to get sound to work. I now got it working perfectly with 32-bit Fedora 10, not working at all despite loaded sound modules with 64-bit Fedora 10. The webcam works well with camstream. Have not tried to make use of the fingerprint scanner on my system (works in Windows Vista, does not work in Windows 7 Beta) or the IR port. A 16 GB SDHC card (Transcend) also works nicely (does not work with Scientific Linux 5.2 = RHEL 5.2) and is fast = 2x as fast as an 8GB Supertalent Pico-C USB stick that sells at almost the same price. A Kyocera printer (FS1300-D) running on a desktop on the same LAN was recognized instantly by the Fedora installation. Getting WLAN was painful, it sometimes works and sometimes does not - not an issue of distance. the router sits exactly behind the laptop (15 cm). Why this is a problem, I do not understand. It is most likely unrelated to the laptop itself. I have it on the network via eth0. The graphics card is so-so for my purposes. It is nice that it has 1GB of VRAM, but it is slower than an 8600GTS I had previously, even though it has the same number of shaders and almost the same clock. This matters for me, as I use NVidia cards for computing (via CUDA). The laptop is meant as a demo machine to take on the road.

In summary: It is a very nice laptop for running Linux, at a decent price, Mostly works out of the box. When using 32-bit Fedora 10, try to download sound-related RPMs until it works - . and at some stage just 'modprobe snd-hda-intel', after that it will be fine- The brightness script shown here is very useful, as sometimes Fn-A works and sometime is does not and using it at anything other than 100% brightness I found hard. The display contrast seem somewhat shallow, I found that the display quality improves significantly (for my taste) if I incline the display about 30 degrees from the vertical position.

He instalado linux ubuntu 8.10 dentro de windows en el ASUS M50VN, la tarjeta gráfica tras habilitar los controladores restrinbgidos estando conectado a internet funciona perfectamente, la tarjeta de sonido tras instalar el .deb del enlace de esta página funciona correctamente tanto por altavoces como por auriculares, brillo, sonido , teclas fn de momento funcionan todas correctamente.

I installed linux ubuntu 8.10 inside windows in ASUS M50VN. The graphics card works perfectly, and the sound card after installing the .deb that I download of the link on this page works correctly for both speakers and headphones, brigthness, the fn key function seems work correctly.
Sorry but my english isn't very good.

Hi again!

I found this useful to fix my brightness problems under Ubuntu:

Potty DJ, 2009/01/08 21:48

Installed Ubuntu 8.10 on Asus M50vn-Ak031C; first time I install a Unix system in my experience.

Had some difficulties installing video enhanced drivers and to make audio work, but after the Ubuntu updates I was able to activate the video drivers and after reading this page now also the audio system is working (thanks)

I had to increase brightness because the standard default was quite dark, but also in Windows, and anyway all the fn+buttons combinations are working.

I'm actually surfing, watching videos, doing office actions with no problems.
Thanks for this page, I'll keep an eye on it
