[求助]从7.10升级到8.04后的显卡驱动和分辨率问题

[brglng]

我系统原来是7.10，nVidia 7300LE的显卡，原来的分辨率是1280*1024，今天用“更新管理器”把系统升级到了8.04，分辨率就只有800*600了，用displayconfig-gtk最高能调到1024*768，到1280*1024就会花屏。用“受限驱动管理器”安装驱动后分辨率就会自动变成800*600，而且nvidia-settings显示没有启用nvidia驱动，3D桌面也无法开启。用nvidia-xconfig也不行。

xorg.conf内容如下：

代码： 全选

# xorg.conf (X.Org X Window System server configuration file)
#
# This file was generated by failsafeDexconf, using
# values from the debconf database and some overrides to use vesa mode.
#
# You should use dexconf or another such tool for creating a "real" xorg.conf
# For example:
#   sudo dpkg-reconfigure -phigh xserver-xorg
