The machine at hand features a Pentium-M CPU at 1.5 GHz. It offers a parallel port, a port for the docking station, a VGA- and TV-Out, a FireWire port and 4 USB 2.0 ports. It has a PC-Card slot, a Modem (AC97 Softmodem), GigaBit-LAN (Broadcom BCM5788) and a built-in DVD/CD-RW drive (Toshiba SD-R2512). It also incorporates a SD/MMC-Card slot. The graphics chip is a Mobility Radeon 9600 (M10) from ATI with 64 MB VRAM which outputs to a 15" TFT at SXGA+ resolution (1400x1050). As this is a Centrino laptop, it is based on the i855PM chipset and includes the WLAN chip Pro/Wireless 2100 from Intel. The harddisk is an astonishingly fast Hitachi Travelstar (measured 26 MB/s with hdparm) and 60 GB in size. The whole laptop, including batteries, weighs approximately around 3 Kg.
You can reach the BIOS via
on startup lets you choose between several boot devices (hard disk, cd,
removable). Note that there is a new BIOS 0206A available from
ASUS(ftp://ftp.asuscom.de/pub/NOTEBOOK/M6x00N/Bios/). You can use
FreeDOS(http://www.freedos.org/) for flashing.
It was installed with Novell/SuSE 9.0 which was a rather painless procedure. Afterwards, kernel 2.6.3 with patches for SWSUSP, ACPI, DSDT-initrd and laptop-mode was installed. Do not touch kernel 2.6.4 for this machine, since many things did not work out for me with that kernel version, like Modem, 3D, WLAN.
XFree86 runs out of the box with the free radeon driver. Unfortunately, this driver does not supply 3D acceleration at the moment, so you have to switch to the proprietary driver from ATI (which only supports i386) for that. But do not use kernel 2.6.4, because the module
fglrx from driver package version 3.7.6 segfaults on this kernel. XFree86 still runs without the kernel module, but also without 3D acceleration. There are several disadvantages when using the proprietary driver: the console screen is b0rked, external VGA does not work (see below), swsusp does not work (see below). The display resolution runs smooth at SXGA+.
The touchpad works with
works great and gives you the mouse buttons you miss.
For X11 always disable
gpm to prevent the mouse from behaving weird.
The console runs fine with
radeonfb at SXGA+. You lose the ability to work on the console when using the proprietary drivers from ATI, because the screen becomes garbled and unreadable.
You may switch the TV display type between NTSC and PAL
in the BIOS. Dunno if
Works very well on the console or XFree86 with the free
radeon driver. You cannot switch between the different modes with Fn+F8, although the ACPI events are recognized (ACPI4ASUS version 0.28).
fglrx does not work well. The console on the external display shows the same garbage as the internal display. XFree86 disables the external output when starting and the control tool from ATI does not seem to save the configured values. Perhaps playing around with the options DesktopSetup and MonitorLayout in XF86Config might help.
PCMCIA works out of the box with
Although the device seems to be another socket for PC Cards, as
cardctl ident reveals, a tested SD-Card from SanDisk did not work. Instead it broke everything in the kernel which was somewhat hotpluggable and the machine had to be rebooted to make it work again.
The network interface works with the
tg3 kernel driver with 2.6.3 and should work with
bcm5700 for 2.4 which you might have to download from Broadcom(http://www.broadcom.com).
Currently, there are theoretically three possibilities to make this chip running:
ipw2100from Intel(http://ipw2100.sf.net) seems to work better and better with every release. Try this one first.
ndiswrapperfrom the community(http://ndiswrapper.sf.net) did not work well with versions 0.5 and 0.6 in this laptop, the current version 0.8 might work better. Both versions succeed in loading and setting up the radio,
iwconfigshows sensible values and
ifconfigshows the configured IP address. But a ping does not succeed and thus no other IP connections. The same driver (0.5) works with the same WLAN-hardware and the same kernel in an ASUS M2400N. An unload of the module afterwards freezes the machine.
driverloaderfrom Linuxant(http://www.linuxant.com) was tested in version 1.64. It behaves very similar to
ndiswrapper. The device seems to be operational, but nothing happens when pinging. When unloading the kernel module
driverloaderafterwards, the system freezes.
ACPI seems to work in a way. You need a patched DSDT to have AC-Adapter and Batteries working. See the page from Andre Messerschmidt(http://www.isis.de/members/~messersch/asus-m6800n.html) for the DSDT and the ACPI4Linux pages(http://acpi.sf.net/dsdt/index.php) for instructions and more context. Or you apply a patch from mrhammy2.ath.cx(http://m6n.ath.cx/forum/).
Standby has only been tested briefly and it does not seem to work. The machine wakes up at once.
It seems to work with kernel 2.6.7, but it is important to define
acpi_sleep=s3_bios on the kernel command-line (or lilo.conf or menu.lst or ...). You need a custom script to stop/start services, unload/load modules (e.g. USB) and so on. That script should
echo -n "mem" > /sys/power/state to do the actual suspension. Caveats: Sometimes, the USB mouse has to be plugged in and out of different ports for several times. WLAN is dead after the resume, which is somewhat known at bugzilla.kernel.org(http://bugzilla.kernel.org/show_bug.cgi?id=2643).
With a properly configured suspend.conf (unload USB, proprietary drivers), SWSUSP2 (220.127.116.11, 2.6.3-test6) works well, if there would not be the proprietary kernel module from ATI. When this modules is loaded, the system seems to enter the suspension process, but does not power off. After powering it on again, the system starts without taking notice of any suspension processes. And since the console screen is b0rked (see above), you cannot see where the suspension hangs. It works without
Using version 18.104.22.168 with kernel 2.6.7 works fine with the free
radeon driver unless you use an USB input device. If the driver
usbhid is loaded on resume, the system freezes.
speedstep-centrino should be chosen. The user-space daemon
cpufreqd runs fine with it. Take care to include the old kernel-APIs for cpufreq in the config, because the daemon shipped by SuSE 9.0 does not understand sysfs.
All Hotkeys work with the driver
acpi_asus. They can be configured via the
Sound works with Advanced Linux Sound Architecture - ALSA driver
slmodem (slamr) from SmartLink(ftp://ftp.smlink.com/linux/unsupported/), version 2.9.6 or later can be loaded, although it was not possible to establish a connection. According to
this thread(http://m6n.ath.cx/forum/viewtopic.php?t=8), the machine contains a proprietary CTX22 codec which is and will be unsupported by slmodem.
hsfmodem offered by Linuxant(http://www.linuxant.com/drivers/hsf/full/downloads.php) definitely works with kernel 2.6.7 (+ patches for acpi, swsusp2 and m6n), you can even hear the modem dialing and connecting. Alas you have to pay for a driver at full speed or you have to live with 14.4 kbps.
Similar to the ASUS M2400N, IrDA does not seem to work correctly with 2.6 in SIR mode.
irattach cannot see other devices than the laptop itself. Check Jean's pages(http://www.hpl.hp.com/personal/Jean_Tourrilhes/IrDA/IrDA.html#config) about the setup for /dev/ttyS1.
Fortunately, FIR seems to work with the driver
nsc-ircc, at least
irdadump can see other devices. Be careful to unload all serial drivers which could come in the way, like
irtty-sir. The IRQ routing seems to work better here than in M2400N, because no quirks like
acpi_irq_balance are needed for the M6800N.
With kernel 2.6.7, it does not work anymore with the default options for the kernel module. You need a line like
options nsc-ircc irq=3 dma=3 io=0x2f8 dongle_id=0x09 in your
/etc/modprobe.conf (or whatever your appropriate configuration file might be called). The device then shows up as some IBM stuff and not as HP stuff as it was in older kernels.
The drive works fine on
/dev/hdc, both reading and writing DVD/CD-RWs.
Works out of the box. Tested with USB Mouse and Harddisk (2.0).
ohci1394 module loads fine, though FireWire was not really tested due to the lack of a proper device.
