Gnome3未正确显示

Question

我相信这个问题以前已经被问过了，但是我似乎无法在这个网站上找到它，所以就这样做了。

我的gnome3看起来不应该。当我第一次安装gnome-shell时，它正常工作，但是在重新启动一次之后，这个接口看起来就像典型的gnome接口。

我正在寻找一个答案，为什么这种行为存在，以及如何解决它。

请注意，我以前遇到过这个问题，我(不小心)让它在Ubuntu11.10中工作，所以不太可能是硬件错误。

gnome-shell --replace的结果，它确实在顶部显示了gnome3条，还有超级键功能，但是这些窗口都是浮华的，很难在窗口之间导航。这是终端的输出。

gnome-shell --replace

上次apt升级后也有同样的错误。但是使用gnome--shell--替换它实际上已经启动，即使它确认了错误。

如果你用被禁止的司机做你的fglrx卡。一种解决方案是从AMD下载amd-driver-installer-12-4-x86.x86_64，使用以下命令：

wget http://www2.ati.com/drivers/linux/amd-driver-installer-12-4-x86.x86_64.run
sh amd-driver-installer-12-4-x86.x86_64.run --extract
cd fglrx-install.NDh3QS/common/lib/modules/fglrx/build_mod
vim fglrx.patch

并增加：

fixed fgrlx compilation error on 32-bit x86 arch with kernel 3.3-rc4 due to commit:
https://github.com/torvalds/linux/commit/f94edacf998516ac9d849f7bc6949a703977a7f3
later modified (in 3.3-rc5) by commit:
https://github.com/torvalds/linux/commit/7e16838d94b566a17b65231073d179bc04d590c8#diff-1
and finally backported to kernel 3.2.8.

This new version adds support for the 3.4 kernels, where some ASM header
file was splitted into several smaller files, so we have to explicitally
include the new file <asm/fpu-internal.h>.

Since 3.4-rc2, cpu_possible_map has been definitely removed. Let's use
cpu_possible_mask instead. This is probably required also for 64 bit kernels.

然后执行

patch -p1 < fglrx.patch
cd ../../../../
./ati-installer.sh 8.961 --buildpkg Ubuntu/precise
cd.. 
sudo dpkg -i *.deb
aticonfig --initial

现在内核模块位于/usr/src/fglrx-8.961，现在使用sudo dkms "remove/build/install" fglrx/8.961重新安装(添加未来的修补程序)就更容易了，如果需要更多信息，可以阅读dkms的手册页。

“环境:退步”意味着您正在运行所谓的gnome会话-回退，它实际上是设计成gnome 2的。尝试退出并更改会话(可以通过登录栏上方的小圆按钮)工作。
