so, nach neu einrichten des xservers kann ich den enable befehl nun ausführen.
was nichts daran ändert, das mir xrandr immer noch nur 60 herz anbietet.

hier meine xorg.conf

Code:
 # /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

Hier wusste ich nicht die werte, ich hab kein Monitorhandbuch, die werte stehen nicht hinten auf dem monitor, und der im ubuntu online handbuch gelistete befehl um es herauszufinden gibt keine antwort zurück. also hab ich einfach die werte eingetragen, die ich eben brauche. 85 Hz überall. Aber selbst wenn das Falsch ist (was sehr warscheinlich ist...) es funktioniert genauso gut oder so schlecht wie vorher.
