RHEL 5 修改分辨率方法




  • Display工具配制方法:
    1、进入桌面后,点击System -> Administration -> Display,选择Hardware,点击Monitor Type后面的Configure(默认是autoconfigured),在新窗口中选择Generic CRT Display,选择适合你的分辨率,我的是1024x768。点击OK退出。
    2、回到刚才Display Settings的窗口,切换到第一个标签页Settings,在Resolution的下拉菜单中,会发现多出了一些分辨率,选择1024x768,点击OK退出。
    3、退出当前用户,System -> Log Out。
    4、系统再次回到登录界面时,你会发现分辨率已经修改成功了。
    注意,在选择Generic CRT Display那一步,不要选下面的Generic LCD Display,虽然我用的是LCD,但选了之后我发现设置成1024x768,注销后分辨率并不是1024x768,似乎是1280x800,不知道为什么,后来选Generic CRT Display设置就正常的。

    2.gnome-display-properties工具配制方法:
    用命令 gnome-display-properties 调出一个窗口,在该窗口中可以看到分辨率和刷新率,立即将其设置成1024x768,成功。且刷新率也自动地调成了 85Hz ,成功。

    这里稍稍讲一讲这两种工具的区别:system-config-display 是系统管理员用的,使用该命令,需要具有 root 权限。普通用户无法使用。那么,普通用户若要调整分辨率的话,该怎么办呢?只能使用 gnome-display-properties 这个命令了。据书上所言,普通用户使用这个命令来调整分辨率,只能向分辨率较低的值调,而不能向分辨率高的方向去调。
