按 下面的步骤去做，改变分辨率。你是在虚拟机下面装的吧？
xp系统下的虚拟机中安装了linux后，虚拟机VMware中的linux界面太小，是由于
linux分辨率太低(通常为800×600)造成的，可以通过安装VMware Tools来更改分
辨率到1024×768来解决这个问题，下面说明安装VMware Tools并配置分辨率的
步骤：
1.安装工具。让虚拟机运行于窗口状态，不要全屏，按Ctrl+Alt让鼠标释放出来。在VMware的菜单栏上选择"虚拟机/安装虚拟机工具(VM/Install VMware Tools...)"。然后切换到客户操作系统，即Linux。
2.挂载光盘。
# mount /dev/cdrom /mnt/cdrom
3.执行命令。进入虚拟光盘，可以看到有两个文件，一个是压缩包，一个为rpm包。直接运行rpm包安装，命令行也可。rpm -Uvh VMwareTools-版本号-版本号.i386.rpm
# cd /mnt/cdrom
# ls -l
有两上文件 ：
VMwareTools-5.5.1-19175.i386.rpm
VMwareTools-5.5.1-19175.tar.gz
并把这两个文件拷贝到你的文件下 如 /tmp
#cp VMwareTools-5.5.1-19175.tar.gz /tmp
#cp VMwareTools-5.5.1-19175.i386.rpm /tmp
#cd /tmp
#rpm -ivh VMwareTools-5.5.1-19175.i386.rpm
4.上述操作完成后，进入/usr/bin目录，查找vmware-config-tools.pl.找到后，运行它。
5.一路回车
6.
#tar -xzvf VMwareTools-5.5.1-19175.tar.gz
#cd vmware-tools-distrib
#./vmware-install.pl
Creating a new installer database using the tar3 format.
Installing the content of the package.
# 安装过程的画面，全部使用默认值，一直按 Enter 就对了

The installation of VMware Tools 5.5.1 build-19175 for Linux completed
successfully. You can decide to remove this software from your system at any
time by invoking the following command: "/usr/bin/vmware-uninstall-tools.pl".
Before running VMware Tools for the first time, you need to configure it by

You can now run VMware Tools by invoking the following command:
"/usr/bin/vmware-toolbox" during an XFree86 session.
To use the vmxnet driver, restart networking using the following commands:
/etc/init.d/network stop
rmmod pcnet32
rmmod vmxnet
depmod -a
modprobe vmxnet

在\etc 目录下找到inittab文件VI 它，找到id:5:initdefault:改成id:3:initdefault: 这里5代表图形界面 3代表命令行的界面
按照Readme中的安装方法，一步步按照默认的设置下来，出现如下错误：
What is the location of the directory of C header files that match your running kernel? [/usr/src/linux/include]The directory
of kernel headers (version 2.6.18-8.el5xen) does not match.
可以使用
[root@localhost ~]# uname -r // 查看内核版本号
查看目录/usr/src/ 根本没有linux这个目录
在网上收到资料：没有安装 kernel-xen-devel rpm包，在安装盘中找到这个rpm包：kernel-xen-devel-2.6.18-8.el5.i686.rpm
安装：
[root@localhost ~]# rpm -ivh kernel-xen-devel-2.6.18-8.el5.i686.rpm
再使用vmware-install.pl安装，即可自动找到配套的the directory of C header files
注重，网上还有人说需要安装的rpm包是kernel-devel，经过测试，安装kernel-devel-2.6.18-8.el5.i686.rpm包后依然无法自动找到the
directory of C header files，假如手动改目录为：/usr/src/kernels/2.6.18-8.e15-i686/include，会出现错误：
The directory of kernel headers (version 2.6.18-8.el5) does not match your running kernel (version 2.6.18-8.el5xen). Even if
the module were tocompile successfully, it would not load into the running kernel.
这就是安装的rpm不正确导致的。
安装好kernel-xen-devel-2.6.18-8.el5.i686.rpm包后，这样就一直enter，装完VMware Tools
在安装的最后阶段，会出现：
Do you want to change your guest X resolution? (yes/no) [no] y

到了这步，千万别重启看效果，还要修改xorg config设置，不然重启后会报X-WINDOWS出错。
进入/etc/X11/，用文本打开xorg.conf，加上以下几段：
Section "Monitor"
Identifier "vmware"
EndSection
Section "InputDevice"
Identifier "Mouse0"
Driver "vmmouse"
Option "Protocol" "Auto"
Option "Device" "/dev/input/mouse0"
EndSection
然后找到 含有"ServerLayout" 的section, 在Section跟EndSection之间加上以下一行。
InputDevice "Mouse0" "CorePointer"
终于大功告成，重启看看效果了
重启之后，resolution不知道为何并没有变化，有待进一步研究，但是Mouse移进移出VMware可以不用再使用Ctrl+Alt键了

肯定是显卡驱动没有正常安装，从官网下载驱动然后按照说明安装即可。注意：一般官方linux下驱动安装的说明都是英文版的。
第一步。。调分辨率。。不行的话就去下载个显卡驱动。。还是不行的话。。就去下载个显卡催化剂什么的。。你去网上找找看
你把分辨率调节一下就可以了，如果是虚拟机的话就把分辨率调成和真机一样就可以了
