O čemu se ovde zapravo radi

Ovaj članak trebalo bi da pojasni proces instalacije GNU Linux distribucije openSuSE 10.2 na Fudžicu-Simens laptop Amilo Pro Pa1538. Amilo Pro Pa1538 je moćan prenosni računar koji u potpunosti može da odmeni stoni računar ukoliko vam ne smeta realtivno mali ekran i metalik izgled (kao što nekima smeta!). Model o kome se radi i čiji sam ponosni vlasnik dolazi u sledećoj konfiguraciji:

Procesor: AMD Turion64 X2 TL52
Memorija : 2Gb DDR2/533MHz
Čipset: nVidia C51D + MCP51
Grafika: nVidia GForce Go 7400/128Mb DDR2
Disk: Western Digital SATA 160Gb (5400rpm)
DVD: DVD-RW/DL
Ekran: 15,4″ WXGA (1280×800) Brilliant View
Zvuk: ALC883 7.1 sound via SPDIF
I/O: 4xUSB 2.0, DVI za eksterni monitor, TV izlaz, Firewire, Touchpad
I/O: Slušalice(SPDIF)/mikrofon, 4 u 1 čitač kartica, Ekspres Card 34/35
LAN: Mrežni adapter 10/100 MCP51
WLAN: bežični mrežni adapter Atheros 802.11 b/g
Modem: softverski Smartlink (Conexant chipset) 56k v.92
Ostalo: Kensington lock

Instalacija

openSuSE 10.2 dolazi sa jezgrom u verziji 2.6.18.8-x a sam proces instalacije je relativno “bezbolan”, i pod pretpostavkom da niste baksuz, sve bi trebalo da proradi iz prve. Kako bilo, ja sam pri kraju instalacije iskusio gašenje računara izjednostavnog razloga što prilikom pokretanja instalacije nisam isključio ACPI podršku (trebalo bi da se podrazumeva kada se radi o instalaciji na bilo koji prenosni računar). Sa uključenom ACPI podrškom prilikom instalacije uspeo sam iz par pokušaja da doguram do kraja jer se laptop gasio 2-3 puta zbog neuključivanja ventilatora za hlađenje procesora i kućišta. Po završenoj instalaciji ACPI funkcije su proradile i oba ventilatora se aktiviraju/deaktiviraju po potrebi. Iz ličnog iskustva preporučujem svima da prilikom pokretanja instalacije isključe ACPI podršku ili izborom odgovarajuće opcije ili prosleđivanjem parametra acpi=off jezgru. Što se tiče hardverskih komponenti sve su uredno prepoznate a jedini dodatni napor iziskvala je instalacija Mad Wi-Fi upravljačkog modula za Atheros bežičnu mrežnu karticu.

Mali saveti velikih majstora

• Posebni funkcijski tasteri za kontrolu zvuka (i verovatno osvetljenja ekrana) mogu se “osposbiti” koršćenjem paketa xmodmap, xbindkeys, nvclock i xosd. Nvclock paket može se naći na ovoj lokaciji sa sve GUI okruženjima za Qt i Gtk2 . Kod mene ne radi kontrola osvetljaja ekrana a prebacivanje na spoljni ekran nije isporbano jer je stona mašina već pronašla novog vlasnika.
  • u /etc/init.d/boot.local dodajte sledeće dve linije
    setkeycodes 0x7f 224
setkeycodes 0x6f 225
  • u osnovnom direktorijumu kreirajte datoteku ~/.Xmodmap sledećeg sadržaja
    keycode 176 = XF86AudioRaiseVolume
keycode 174 = XF86AudioLowerVolume
keycode 160 = XF86AudioMute
keycode 101 = SunVideoRaiseBrightness
keycode 212 = SunVideoLowerBrightness
  • u osnovnom direktorijumu kreirajte datoteku ~/.xbindkeysrc sledećeg sadržaja
    "/home/your_user_name/brightness-up"
SunVideoRaiseBrightness
"/home/your_user_name/brightness-down"
SunVideoLowerBrightness
  • napravite skript brightnes-up script sledećeg sadržaja
    #!/bin/bash
brightness=`/usr/bin/nvclock -S +5 2>/dev/null| grep level:| awk '{print $4;}'`
if [ "$brightness" = "" ]
then
brightness="100%"
fi
echo "Brightness "$brightness | osd_cat -p bottom -A center -c green -d 1
  • napravite skript brightnes-down sledećeg sadržaja
    #!/bin/bash
brightness=`/usr/bin/nvclock -S -5 2>/dev/null| grep level:| awk '{print $4;}'`
if [ "$brightness" = "" ]
then
brightness="15%"
fi
echo "Brightness "$brightness | osd_cat -p bottom -A center -c green -d 1
  • podesite skripte da mogu da se izvršavaju
    chmod +x brightness-up
chmod +x brightness-down
  • kreirajte skript /home/your_user_name/.kde/Autostart/keys sledećeg sadržaja
    #!/bin/bash
/usr/bin/xmodmap ~/.Xmodmap
/usr/bin/xbindkeys
  • i ovaj skript označite kao izvršni
    chmod +x /home/your_user_name/.kde/Autostart/keys
  • ponovo pokrenite X server i kombinacije tastera Fn i kontrole zvuka i osvetljaja bi trebalo da prorade
  • ako sve funkcioniše zahvalite se autoru članka na Gentoo wiki-ju
• Video karta nVidia GForce Go 7400 dolazi sa sopstvenih 128Mb DDR2 RAM-a i bez problema radi u 2D modu. Ukoliko želite da koristite i 3D/OpenGL mogućnosti moraćete da instalirate nVidia upravljačke programe zatvorenog koda što za posledicu može imati “neprijatno” zamrzavanje prenosnika tokom rada bez ikakvog vidljivog razloga. Ovakvo ponašnje iskusili su brojni korisnici GNU Linux distribucija koji koriste kombinaciju nVidia upravljačkih programa i GForce Go 7xxx serije grafičkih kartica a jedino praktično rešenje je isporbavanje različitih verzija nVidia zvaničnih i Beta upravljačkih programa kako bi ste došli do “dobitne kombinacije”.
  Ja sam prvo postavio poslednji zvanični nVidia upravljački program (verzija 100.14.11) i na sreću vrlo brzo ustanovio šta je razlog zamrzavanja koja su usledila. Problem je rešene, takođe srećno, instalacijom Beta upravljačkih programa u verziji 100.14.06 tako da sada sve funkcioniše kako trebe . Glxgears test pokazuje između 2,500 and 2,800 FPS a sve instalirane 3D/OpenGL igre rade.

Nije isprobano

• Smartlink modem – jednostavno ne koristim analogne modeme jer imam ISDN liniju sa Netmod USB modemom
• Express Card utičnica – razmišljao sam o nabavci odgoarajućeg TV prijemnika ali dok se, i ako se to uopšte desi ne garantujem da radi
• Na prenosniku nemam opcioni Bluetooth uređaj tako da ni za njega nisam siguran da li funkcioniše

Installation

With kernel 2.6.18.8-x shipped with openSuSE 10.2 installation process is straight forward and everything works out of the box. Nevertheless, seems like there was a problem with processor fan operating during installation process and laptop automatically turned off couple of times though installation procedeed normally afterwards. Thus, I would suggest that you disable acpi by adding acpi=off kernel parameter. However, after the installation was done I simply started openSuSE with acpi=off and restarted machine afterwards and now everything seems fine – fans are operating normally and what is most important quietly.
Hardware was detected with no problems except Atheros wireless adapter for which to work you have to install madwifi driver.

* Installing MadWiFi kernel modules
You can find a step-by-step guide on openSuSE wiki in the Atheros-madwifi section

Quirks and tips

• Special function keys for controlling audio could be enabled using xmodmap, xbindkeys and xosd. Note that nvclock should also be installed from the following openSuSE repository (you may also install qt or Gtk2 frontend from the same location). I haven’t found a way to enable dimmer (brightness up/down) keys and I haven’t tested the LCD/video OUT function key as I have already sold out my desktop computer.
  • edit /etc/init.d/boot.local and add following 2 lines
    setkeycodes 0x7f 224
setkeycodes 0x6f 225
  • in your home folder create file .Xmodmap
    keycode 176 = XF86AudioRaiseVolume
keycode 174 = XF86AudioLowerVolume
keycode 160 = XF86AudioMute
keycode 101 = SunVideoRaiseBrightness
keycode 212 = SunVideoLowerBrightness
  • in your home folder create file .xbindkeysrc
    "/home/your_user_name/brightness-up"
SunVideoRaiseBrightness
"/home/your_user_name/brightness-down"
SunVideoLowerBrightness
  • create and edit brightnes-up script
    #!/bin/bash
brightness=`/usr/bin/nvclock -S +5 2>/dev/null| grep level:| awk '{print $4;}'`
if [ "$brightness" = "" ]
then
brightness="100%"
fi
echo "Brightness "$brightness | osd_cat -p bottom -A center -c green -d 1
  • create and edit brightnes-down script
    #!/bin/bash
brightness=`/usr/bin/nvclock -S -5 2>/dev/null| grep level:| awk '{print $4;}'`
if [ "$brightness" = "" ]
then
brightness="15%"
fi
echo "Brightness "$brightness | osd_cat -p bottom -A center -c green -d 1
  • make both newly created scripts executable
    chmod +x brightness-up
chmod +x brightness-down
  • create and edit script /home/your_user_name/.kde/Autostart/keys
    #!/bin/bash
/usr/bin/xmodmap ~/.Xmodmap
/usr/bin/xbindkeys
  • make keys autostart script executable
    chmod +x /home/your_user_name/.kde/Autostart/keys
  • restart X or restart laptop and function keys, at least, for audio volume and muting should work
  • if it works don’t thank me as all merit goes to Gentoo wiki project
• nVidia GForce Go 7400 graphics card comes with it’s own 128Mb DDR2 RAM and it works in 2D with no problem but if you wish to enable 3D/OpenGL capability using nVidia proprietry drivers you may experience laptop freezing with no apparent reason. This behaviour has been noticed by many other users of GForce Go 7xxx series and the only solution is to experiment with various nVidia official and Beta driver versions and search for the 64 bit driver that works. Otherwise you can only use 2D cards capability to avoid laptop freezing.
  I’ve tried latest nVidia driver (version 100.14.11) and experienced random freezes and display problems which I solved by switching to Beta driver version 100.14.06 and now everything seems to work fine. Glxgears gives me framerates between 2,500 and 2,800 FPS and all installed 3D/OpenGL games work fine.

Not tested

• Modem – I don’t use it as I have ISDN line built-in Netmod USB modem
• Express Card – thought of ExpressCard TV tuner but till and if I get it I don’t know if Card Bus works
• My laptop came without bluetooth option so I don’t know if that one works

Summary
FSC Amilo Pa1538 is a pretty nice laptop if you don’t mind it’s silverish design (as some do!). It could be a practical replacement for your desktop if you’ve came to conclusion, as I did, that it’s simply hard to keep-up with and administer two computers at home at certain age. It is reasonably light and compact, doesn’t have all the connectors you may (n)ever use but it’s still a reliable and fast machine for a reasonable price.
