我最近在配备 4GB nVidia 显卡的笔记本电脑上安装了 Debian Wheezy 7.6。默认情况下，登录时它会启动到 gnome 经典模式并报告“Gnome 3 加载失败”。此外，有时鼠标指针不一致（滚动和单击时不可见）。
这是以下的输出.xsession-errors：

我不知道这些是什么。我用谷歌搜索并找不到解决方案。是我显卡的原因吗？如果是这样我该如何解决它们？
更新：我真的不想要 gnome-3，而是经典模式。所以，经典模式足够完美就足够了。
答案1
升级内核确实解决了鼠标指针的问题，可以使用 wheezy向后移植。将反向移植存储库添加到您的存储库中/etc/apt/sources.list并发出以下命令：
#login as root
su
#update packages
apt-get update
#install through backports
apt-get -t wheezy-backports install linux-image-3.16-0.bpo.3-amd64 firmware-linux-free
但是，gnome 3 不起作用，我不在乎。除了面板中出现一些丑陋的图标之外，Gnome 后备现在工作得非常完美。
