gnome-fallback.desktop 在 13.10 中是否需要加速图形？

Question

我正在尝试gnome-fallback.desktop在 VncServer 下运行。

升级到 13.10 后，我的 VNC 不再工作 - 它只显示一个空的终端窗口，没有会话。

这些是我安装的会话：

$ ls /usr/share/xsessions/
gnome.desktop                  gnome-fallback.desktop  xfce.desktop
gnome-fallback-compiz.desktop  ubuntu.desktop

这是我的~/.vnc/xstartup文件的内容，gnome-fallback.desktop据我所知，它指向的是：

$ ls /usr/share/xsessions/
gnome.desktop                  gnome-fallback.desktop  xfce.desktop
gnome-fallback-compiz.desktop  ubuntu.desktop

这是日志文件的输出~/.vnc/：

似乎gnome-fallback.desktop现在需要加速图形？这样对吗？

Answer 1

如果我手动启动 gnome-session 曾经启动的事情，它会起作用。虽然字体似乎没有设置。

~/.vnc/xstartup

#!/bin/sh

export XKL_XMODMAP_DISABLE=1
unset SESSION_MANAGER
unset DBUS_SESSION_BUS_ADDRESS

gnome-panel &
gnome-settings-daemon &
metacity &
nautilus &
gnome-terminal &

Answer 2

升级后我遇到了完全相同的问题，我尝试寻找可能的解决方案，但找不到与软件加速问题相关的任何内容。

最后我实在忍不住再去挖掘了，所以我就选择了 xfce4，现在它又可以正常工作了。

这是我的 Xstartup：

#!/bin/sh
unset SESSION_MANAGER
unset DBUS_SESSION_BUS_ADDRESS
startxfce4 &

我的猜测是 gnome-fallback 可能会被破坏，并且以某种方式默认为 gnome3，这实际上需要加速才能工作。

希望这对您有帮助。
