Fujitsu-Siemens AMILO Xi 2550

Russian version of the text. Listed on

I use Debian 7.0 (was 4.0, 5.0 and 6.0). If you use a different distribution drivers and file paths in the table below may be different.

Hardware subsystem Device Driver (kernel module) Control program (daemon) Comments
Processor and motherboard Processor: Intel Core 2 Duo® T8100 2.1 GHz acpi_cpufreq cpufreqd Works fine. Linux kernel recognizes the processor as 4194.65 BogoMIPS. CPU frequencies: 800 MHz, 1200, 1600, 2100 MHz.
Chipset: Intel 965PM + ICH8-M     Works fine.
ACPI acpi acpid Works fine. Suspend-to-disk and resume works. Suspend-to-RAM and resume works.
RAM: 2 G     Works fine.
Disk storage Hard disk: 250 G, SATA, UDMA 133     Works fine, but requires some tuning to turn on DMA. hdparm -t /dev/sda reports: "182 MB in 3.01 seconds = 60.48 MB/sec".
ATAPI DVD+RW ide_cd_mod wodim, dvd+rw-tools Works fine, both reading and burning.
Multimedia Video adapter: ATI Mobility Radeon HD 2600 XT (M76) VESA, ati, radeon, radeonhd, fglrx Console, X Windows VESA and ati work but don't support XVideo; radeonhd works and supports XVideo and acceleration if non-free firmware is available (firmware-linux-nonfree) but it periodically hangs; proprietary fglrx works starting with version 11-5 until version 12-3 but it sometimes hangs during hibernation or suspend. Latest radeon driver works best.
Screen 17", 16:9, WUXGA (1920*1200)   Console, X Windows Works fine. The screen is bright, contrast and glaring. Black color is really black, not dark grey. Colors are intensive. Horizontal angle from which the image looks inverted is very big - 160-170 degrees, almost parallel to the screen. Vertical angle is not as big but still is good enough. On closing the lid the backlight is turned off. There are VGA and HDMI connectors for an external monitor; also there is an S-Video output.
Audio: Intel HD Audio snd_hda_intel ALSA, PulseAudio Works fine.
ALi m5602 1.3Mpx webcam m5602   To make it work use v4l1compat:
LD_PRELOAD=/usr/lib/i386-linux-gnu/libv4l/ mplayer tv:// -tv driver=v4l2 -nosound
Communication Realtek 8169 Ethernet 10/100/1000 r8169   Works fine.
Intel 4965 Wi-Fi b/g/n iwl4965 wireless-tools, hotplug (for automatically loading firmware), wpa_supplicant The firmware is not free. Works fine in both 'g' and 'n' (300 MBits) modes; two bands - 2.4 GHz and 5 GHz; in n-mode real speed is 50-80 MBits - 3-4 times more then in g-mode, but I expected real speed 150 MBits; probably limited by my router or slow disk in my server. At the front side there is a kill switch that turns on/off both WiFi and Bluetooth.
3*USB 2.0 ehci_hcd, uhci_hcd   Works fine.
Bluetooth hci_usb hciconfig, hcitool, sdptool, rfcomm, passkey-agent, obexftp, pppd Works fine.
Keyboard   Console, X Windows Works fine. Almost standard keyboard with a keypad and a Fn key; the Fn key controls speakers volume, screen brightness. The keyboard is good enough; the only two inconvenient points are: arrow keys are small, Home/End require Fn.
Touchpad: SynPS2 psmouse, xserver-xorg-input-synaptics Console, X Windows Works fine. Two-buttons touchpad with acceleration, horizontal and vertical scrolling; it recognizes one-finger tap as the left button click, and two-fingers tap as two buttons. I changed defaults in /etc/X11/xorg.conf a bit:
Option "RightEdge" "5000"
Option "MaxSpeed" "0.4"
Option "AccelFactor" "0.0025"
Option "MaxDoubleTapTime" "80"
Option "RightEdge" "5000" is to make the scrolling area wider.
Multimedia keys (LightTouch)   xbindkeys Work fine except Fn+Volume Up/Down. I mapped the keys using xbindkeys program that calls aumix and xmms command-line client.

Before buying the notebook I tested it by booting Knoppix. All main devices worked fine, so I bought the notebook and installed Debian 4.0. Then I found DMA didn't work. I booted Knoppix - DMA worked. Debian - didn't work. I booted Knoppix once again, copied kernel's .config, recompiled kernel and booted Debian with this new kernel. Now DMA works!

Devices and interfaces I have not tried to configure yet: RAID controller, eSATA, modem, ExpressCard, 5-in-1 cardreader, IrDA remote control, 1.3 Mpx webcam.

The supplied external AC/DC power adapter is big, heavy and hot; on either sides of the adapter there are cords for about 2 meters length. Builtin cooler is very quiet (especially compared with my desktop monster), though not completely silent; it's powerful enough to cool the processor down to 50-60°C (70°C under very heavy processor load like transcoding video, and then cooler increases power and becomes noisy).

Weight 4 kg. Size 385*408*291 mm. Price $1600. Includes a simple case for the notebook. Warranty 2 years.
