DebianOn is an effort to document how to install, configure and use Debian on some specific hardware. Therefore potential buyers would know if that hardware is supported and owner would know how get the best out of that hardware.

The purpose is not to duplicate the Debian Official Documentation, but to document how to install Debian on some specific hardware.

Configuration

Kernel

It won't boot because the ATI DRM of 3.2 kernel is too old. You must either install a more modern kernel (any 3.5 or superior is Ok) or disable radeon module.

It is really recommended to install kernel 3.7 or higher, which has full support for this graphics card, with excellent performance. If you are using squeeze or wheezy, add the experimental repository and install linux-image-3.7-trunk-amd64 and firmware-linux-nonfree (needed for graphics card and other things).

Display

The included open source xorg driver works with a modern kernel, except for the brightness control. Not having brightness control is a real pity. Fortunately, this issue is addressed on linux kernel 3.7, so you should really install it, and firmwares.

Actually the graphics card is pretty good, having a decent performance for a netbook, even if you use multiple monitors. It can play 720p and some 1080i videos. With Chrome (not Firefox), you can even watch full-screen youtube videos, with around 50-70% processor use (at 360p resolution). 3D is good, it can play Neverball with all goodies on at 1920x1080 (Intel 3150 is not even able to do that with all disabled).

External HDMI works perfectly with xrandr. I haven't tested the VGA port but should work as it is detected.

Including this on /etc/xorg.conf dramatically increases performance and improves graphics power management:

Section "Device"
        Identifier "radeon card"
        Driver "radeon"
        Option "AGPFastWrite" "on"
        Option "DisplayPriority" "HIGH"
        Option "RenderAccel" "on"
        Option "AccelMethod" "EXA"
        Option "DMAForXv" "on"
        Option "ClockGating" "on"
        Option "DynamicPM" "on"
        Option "DRI" "on"
EndSection

Audio

Works out of the box. Even HDMI out works on wheezy. (But currently, it seems that HDMI output is not working on SID). But if you hear pops and clicks, must add this to /etc/modprobe.d/alsa-base.conf:

options snd-hda-intel power_save=0 power_save_controller=N

Touchpad

Touchpad works, but xorg is confused about its initial state, which is disabled by default. Just press Fn+F7 before entering into X and it will work perfectly.

Also look at synclient man page.

Power Management

Works out of the box, but only 800 and 1000mhz is detected. Turbo mode (1333mhz) is not detected due to Linux Kernel lack of support. Because of this, it is better to let the BIOS manage the power. Disable any ACPI or power daemon, you don't need them and they provide worse performance.

Fan stops after a while of not using or almost not using the processor. Anyway the fan is very quiet. Actually the hard disk can sound more than the fan (except when using full processor power).

Install amd64-microcode for better processor working.

WiFi

Works with newer kernels, not with 3.2, which you must install if you want the display card to work anyway...

Bluetooth

firmware-atheros needs to be installed. Laptop can be paired, files can be sent to remote peer, or received from the peer after enabled in "Personal File Sharing Preferences" (check box: "Receive files in Downloads folder over Bluetooth").


System Summary

Conclusion

This netbook can run Debian Wheezy almost perfectly, only if you install a newer kernel and are ready to do some tweaks.

This netbook is not recommended for people not ready for some tweaking (if that is your case, Ubuntu 12.10 works out of the box), otherwise, with a little help it is a nice machine to carry on with Debian.
