如何修复“系统正在低图形模式下运行”错误?
我刚买了一台新笔记本电脑,正试图将 Ubuntu 10.04 放在它自己的分区上。安装后,我发现无法更改屏幕分辨率,并且它将我的显示器类型标记为“未知”。我认为问题是我没有安装 nvidia 驱动程序,所以我从 nvidia 的网站下载并安装了它们。
此过程涉及在安装过程中终止 xserver,这并不麻烦。安装驱动程序后,重新启动时出现错误消息,指出 Ubuntu 正在低图形模式下运行。我有 5 个选项可供选择,但没有一个能让我的屏幕分辨率正常工作。
我的新款华硕笔记本电脑上装有 nvidia 550M。华硕 N53SN
全新安装的 Ubuntu 10.04。
我的xorg.conf

运行gksudo gedit /etc/modprobe.d/blacklist.conf
,并将以下内容添加到底部:
blacklist vga16fb
blacklist nouveau
blacklist rivafb
blacklist nvidiafb
blacklist rivatv
...保存并重新启动。
