Linux支持宽屏显示器

z-l-dragon

上个礼拜买了19英寸的ViewSonic显示器,发觉在Linux下(Ubuntu)不能把分辨率设置到1440 x 900.研究了一下X Windows的显示配置,只需稍微修改一下即可.

原始的xorg.conf (/etc/X11目录)如下
# /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 xorg.conf(5) manual page.
# (Type "man 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
