gnome-fallback.desktop是否需要在13.10中加速图形？
我想在VncServer下运行gnome-fallback.desktop 。
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，据我所知，它指向gnome-fallback.desktop ：
#!/bin/sh # Uncomment the following two lines for normal desktop: unset SESSION_MANAGER unset DBUS_SESSION_BUS_ADDRESS # exec /etc/X11/xinit/xinitrc gnome-session --session=gnome-fallback.desktop & #gnome-session --session=gdm-session & [ -x /etc/vnc/xstartup ] && exec /etc/vnc/xstartup [ -r $HOME/.Xresources ] && xrdb $HOME/.Xresources xsetroot -solid grey vncconfig -iconic & x-terminal-emulator -geometry 80x24+10+10 -ls -title "$VNCDESKTOP Desktop" & x-window-manager &
这是~/.vnc/日志文件的输出：

看来gnome-fallback.desktop现在需要加速图形？ 它是否正确？
如果我手动启动gnome-session用来启动它，它会有用。 但似乎没有设置字体。
〜/ .vnc / xstartup中
#!/bin/sh export XKL_XMODMAP_DISABLE=1 unset SESSION_MANAGER unset DBUS_SESSION_BUS_ADDRESS gnome-panel & gnome-settings-daemon & metacity & nautilus & gnome-terminal &
我在升级后遇到了完全相同的问题，我试图寻找可能的解决方案，但我无法找到与软件加速问题相关的任何内容。
最后我再也不能被挖掘了，所以我只是选择了xfce4，现在它再次完美无缺。
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，并且默认为gnome3，这实际上需要加速以便工作。
希望这对你有所帮助。
这是一个（非常令人失望的）Gnome问题。 这个问题已经超过一年了，仍然存在于14.04 LTS中。
从这个线程使用–disable-acceleration-check的解决方案对我来说不起作用。

是的，作为一种解决方法，xfce4或fluxbox（运行startfluxbox）将起作用。
