在硬件驱动那里装上受限驱动，重启后分辨率变成了640*480，在首选项－屏幕分辨率那里只有这个跟320*240两个选项，搜了搜贴子，手动加上了Modes "1280x1024_60" ，没有作用，用sudo sudo dpkg-reconfigure xserver-xorg 又似乎没有显示设置的选项。后来手动执行了nvidia-xconfig，重启之后，显示频率就超出范围了，但从开机到显示“显示频率超出范围”的分辨率却一直没错（我是设置成自动登陆的，就是过了进度条，显示了鼠标就超出了）。于是进入控制台，修改
成Horizsync 30.0 - 110.0
Vertrefresh 50.0 - 150.0
仍然是超出范围。改回来后，在Section "Screen" 加上Section "Screen" 也是一样。。。Horizsync 31.0 - 56.0
Vertrefresh 56.0 - 76.0
实在是没办法了，贴出我执行了nvidia-xconfig后频率超出范围但尚未修改的xorg.conf
问题已经解决了，还是装的最新的驱动，然后在“应用程序－其它－显示器和显卡”里设置好显示器，分辨率，重启，一切搞定。# nvidia-xconfig: X configuration file generated by nvidia-xconfig
