Fiks for skjermfeil

De gangene jeg har gjort forsøk med Ubuntu/Kubuntu/Xubuntu på ppc-maskiner fra Apple1, har jeg slitt med at bare 2/3 av skjermen brukes; den høyre tredelen er svart, den nedre tredelen av skjermen looper toppen. 12″ er fra før av ikke alt for stort, så det er selvfølgelig irriterende. Med litt søking og hjelp fra flere foraer, har jeg kommet frem til at følgende prosedyre funker2:

  • åpne applications->tilbehør->terminal
  • skriv
    sudo dpkg-reconfigure xserver-xorg
  • skriv
    sudo nano /etc/X11/xorg.conf
  • kopier det følgende, som jeg fant på ubuntuforums, med ctrl3 -c
    #PPC xorg.conf that works
    # /etc/X11/xorg.conf (xorg X Window System server configuration file)
    #
    # This file was generated by dexconf, the Debian X Configuration tool, using
    # values from the debconf database.
    #
    # Edit this file with caution, and see the /etc/X11/xorg.conf manual page.
    # (Type "man /etc/X11/xorg.conf" at the shell prompt.)
    #
    # This file is automatically updated on xserver-xorg package upgrades *only*
    # if it has not been modified since the last upgrade of the xserver-xorg
    # package.
    #
    # If you have edited this file but would like it to be automatically updated
    # again, run the following command:
    # sudo dpkg-reconfigure -phigh xserver-xorg

  • lim inn i nano/terminalvinduet med shift-ctrl-v
  • lukk vinduet med ctrl-x og lagre på spørsmål med y.
  • kjør omstart på maskinen

Så er min erfaring at plassutnyttelsen blir langt mer effektiv. Og det er jo greit!

  1. alltid den samme 12″ iBook G3 500mHz []
  2. testet i Xubuntu 9.10 []
  3. med ctrl mener jeg ctrl []
