Gnome3 显示不正确

Question 1

上次 apt-get upgrade 后出现同样的错误。但使用 gnome-shell --replace 后，即使确认有错误，它实际上也可以启动。

如果您正在为 fglrx 卡使用禁止的驱动程序。一种解决方案是从 AMD 下载 amd-driver-installer-12-4-x86.x86_64.run，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

并添加：

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，现在更容易重新安装（添加未来的补丁），如果您需要更多信息，sudo dkms "remove/build/install" fglrx/8.961请阅读手册页。dkms
