==Introduction==

This Page describes how to configure a Linux System on the Acer Extensa 355 (formerly known as TI Extensa 355). These instructions are [http://www.debian.org/ Debian] specific but most of them will work with other distributions.

[[ExtensaTechInfo.html|The technical specifications of the Extensa 355.]]

==Installation==
I installed my Debian system over a PCMCIA-Ethernet card via FTP. Other possible methods include installation via NFS (with a PCMCIA card, PLIP (parallel port/Laplink cable), SLIP (serial port/null-modem)), floppy disks. Please refer to the documentation of your distribution for further information about the installation.

==The Kernel==
To use all the features (sound and APM) of your notebook you'll have to compile a new kernel. I suggest to use the newest 2.2.x kernel.

==Sound==

I'm using the ALSA opl3sa2 driver. Since the newer versions of the ALSA driver come with native Plug'n'Play support, you no longer have to mess around with the isapnp tools.

* Compile and install the alsa-driver package (refer to the INSTALL file for detailed instructions):
 ./configure --with-isapnp=yes --with-cards=opl3sa2
 make install
 ./snddevices

* Compile and install the alsa-lib and the alsa-utils packages.
* Add the following lines to /etc/conf.modules:

 alias char-major-116 snd
 alias snd-card-0 snd-card-opl3sa2
 alias char-major-14 soundcore
 alias sound-slot-0 snd-card-0
 alias sound-service-0-0 snd-mixer-oss
 alias sound-service-0-1 snd-seq-oss
 alias sound-service-0-3 snd-pcm1-oss
 alias sound-service-0-12 snd-pcm1-oss
 options snd -k snd_major=116 snd_cards_limit=1 \
  snd_device_mode=0660 snd_device_gid=29 snd_device_uid=0
 options snd-card-opl3sa2 -k snd_isapnp=1 snd_index=0 \
  snd_id=CARD_1 snd_port=0x370 snd_wss_port=0x530 \
  snd_midi_port=0x300 snd_fm_port=0x388 snd_irq=10 \
  snd_dma1=1 snd_dma1_size=64 snd_dma2=0 snd_dma2_size=64

* Try playing a .wav file using aplay. You won't hear anything because all channels are muted by default. Use alsamixer (or alsactl) to unmute the needed channels and use <Fn>-<F5> to adjust the volume setting of the notebook.
* Information about the loaded sounddrivers can be found in /proc/asound

==APM==

The APM (advanced power management) works fine with the 2.0.x and 2.2.x kernels. Suspend and "power off on shutdown" works out of the box, just compile APM support in the kernel.
I finally got the Hibernation mode (Suspend to disk) working (Many thanks to Arthur Darquandier): 

Create a hibernation file on a DOS-FAT (Yes, that's sad) partition with the sleepmgr, which can be found on Acer's support pages. 
Boot DOS and call sleepmgr before starting Linux. (You have only to do this once.) 
Call <code>hdparm -m16 /dev/hda</code>. (To do this automatically at boot time, you'll have to create a init script in <code>/etc/init.d/</code> and create the symlinks in <code>/etc/rcX.d/</code>.) 
The hibernation mode should work now. Just set up the BIOS correctly. 

==Framebuffer==

To use the text console at a resolution of 800x600 you can compile framebuffer support into the kernel. Just activate the following options in the "Console drivers" section of <code>make menuconfig</code>: 
  [*] VGA text console
  [*] Video mode selection support
  [*] Support for frame buffer devices
  [*] VESA VGA graphics console

==XFree86==

The CT65550 chipset is supported by the SVGA server of XFree. Because I don't like 256 colors, I tried 800x600 with 16 bit depth. It worked, but I had some strange effects on the bottom of the screen, so I reduced the resolution to 800x590 with the option "no_stretch" enabled. I think, some acceleration functions are disabled because of the memory (922 kB are used with 800x590x16bit). But at least for me, lots of colors are more important than high performance.

Relevant portions of <code>/etc/XF86Config</code>:
 Section "Monitor"
    Identifier  "DSTN"
    VendorName  "Unknown"
    ModelName   "Unknown"
    HorizSync   25-65

 EndSection

        Modes       "800x590"
        ViewPort    0 0
    EndSubsection
    Subsection "Display"
        Depth       16
        Modes       "800x590"
        ViewPort    0 0
    EndSubsection
 EndSection

==The Keyboard==

At least on the swiss german keyboard, for the "AltGr" key you have to press "Fn" and "Alt" simultaneously and there is only one "Ctrl" key on the left. So I remaped the "AltGr" key on the "Windows" key and the "Ctrl" key on the "Start" key. In XFree, I had to disable XKB to do that. I'm sure, it could be done with XKB, too but I didn't find any docs. Basically you have to change two entries in /etc/default.keytab: 
 keycode 126 = AltGr
 keycode 127 = Control

And in ~/.Xmodmap 
 from:                                to:
 ! Windows key, left and right        
 keycode 115 = Super_L                keycode 115 = Multi_key
 keycode 116 = Super_R                keycode 116 = Mode_switch
 
 ! Start key, right
 keycode 117 = Hyper_R                keycode 117 = Control_R
 
                                      add Mod3 = Mode_switch
 add Mod4 = Super_L Super_R           add Mod4 = Super_L Super_R
 add Mod5 = Hyper_R                   add Mod5 = Hyper_R

I know, this is an ugly hack, but at least it works.
