在基于virtual box的oracle linux上布署11g rac，执行grid infrastructure 集群件安装的时候，oui界面显示不全，右下角缺少next与cancel按钮，显示如下
点击system-->administrator-->display，将分辨率由640x480调整至800x600，然后logout重新登陆，问题依旧。
编辑/etc/x11/xorg.cnf文件，设置分辨率参数modes，显示如下

然后重启系统，问题依旧，并且点击system-->administrator-->display，发现可选分辨率还是只有640x480和800x600。
百度了一下，网上说要安装virtual box增强功能，具体操作如下
点击“安装增强功能”后，桌面会出现vboxadditions _4.3.10_93012光盘图标，点击图标后，找到“vboxlinuxadditions.run”文件
双击运行，屏幕输出以下信息
verifying archive integrity... all good.

然后重启系统解决问题。
备注：如果双击“vboxlinuxadditions.run”文件，屏幕没有输出上面的信息，可以在命令行下进去文件所在路径，以root用户执行。
