[size=18]我的电脑现在运行其他一切正常,但就是分辨率只能在640*480一个选择,怎么改都不行,具体情况是这样的:
从系统开始安装时分辩率就只有640*480可调,安装完成后,系统运行正常,但就是分辨率选项只有640*480一个选择,我察看了设备管理器,发现我电脑的显卡已经被系统自动认出,是集成显卡.型号是Intel Corporation 82845G/GL,然后按网上提供的方法,编辑sudo gedit /etc/X11/xorg.conf ,是这样的:显示器和显卡的型号系统已经自动认出了,而且非常的准确

但没有调整刷新率的那两行,我手工输入了刷新频率的那两行,改好后是这样的:

改好后保存退出重进,分辨率仍然只有一个640*480选项,我怎么也改不了,我都快绝望了,大家一定要帮帮我呀!!

是不是,出了桌面效果及能调分辨率就代表显卡驱动被成功安装了呢,
