分辨率问题，希望高手帮忙解决一下了

[hangzhou]

先说机器配置：P4 1.6 512内存 ATI显卡，装的Ubuntu 8.04.1版本，
机器出现这样的事情，就是在输用户名密码的时候是800*600的分辨率，而进入之后又是1024*768的分辨率，有没有办法在输入用户和密码的时候就改为1024*768的分辨率，网上找了很久没有找到能解决的方法了，希望有人能指教一下了，先谢了

貼xorg.conf出来看看

[hangzhou]

我是新手，什么都不懂， 还请多多指教，我把xorg. conf复制出来了.如下：
# xorg.conf (X.Org X Window System server configuration file)
#
# This file was generated by failsafeDexconf, using
# values from the debconf database and some overrides to use vesa mode.
#
# You should use dexconf or another such tool for creating a "real" xorg.conf
# For example:
# sudo dpkg-reconfigure -phigh xserver-xorg

呵呵,不好意思,没看出来那里有什么问题

[hangzhou]

还是不行了，真是怪事了，输用户密码那个界面字体也特别大了，不过进了之后就正常了，不影响使用，就是看起来不舒服了，显卡驱动正不正常要怎么看啊，哪位能告诉我一下了

glxinfo |grep -e 'direct' -e 'OpenGL'

能说的详细点吗，看的不是太懂了，
