I've had this issues across multiple machines and multiple versions of Ubuntu desktop (all 10.04 or later). 我在多台计算机和多个版本的Ubuntu桌面（所有10.04或更高版本）上遇到了这个问题。 Usually it happens with an old laptop I've put Ubuntu on but now it's happening on my primary dev machine (a quad-core PC recently upgraded to Ubuntu 12.04 desktop). 通常情况下，这是在我安装了Ubuntu的旧笔记本电脑上发生的，但现在在我的主要开发机（最近升级到Ubuntu 12.04台式机的四核PC）上发生了。 The problem is this - I can connect to the machine and login with the password, the initial screen looks fine but never refreshes. 问题是这样的-我可以连接到机器并使用密码登录，初始屏幕看起来不错，但是从不刷新。 I can see the monitor for the machine across the room and can see the mouse move and the menus pop up but the image of the screen on the PC in front me running the VNC viewer never updates. 我可以看到整个房间的机器监视器，可以看到鼠标移动和弹出菜单，但是运行VNC查看器的前面PC的屏幕图像从未更新。 So the mouse and keyboard commands are working. 因此，鼠标和键盘命令有效。

I think it is an Ubuntu config issue because this PC used to work just fine with 9.04, 10.04, and 11.10 (over the past couple of years). 我认为这是Ubuntu配置问题，因为该PC过去在9.04、10.04和11.10（过去几年）中都可以正常工作。 I've also had a couple of laptops that used to have this issue with older Ubuntu's but don't with 12.04. 我也有几台笔记本电脑，以前的旧版Ubuntu曾遇到此问题，但12.04版则没有。

Additional info: 附加信息：

The Win7 PC I'm trying to use to control the Ubuntu PC is connected via 2 DLink 8-port gigabit routers. 我试图用来控制Ubuntu PC的Win7 PC是通过2个DLink 8端口千兆路由器连接的。 The Ubuntu laptop I usually control via VNC is typically only connected to the network via wireless. 我通常通过VNC控制的Ubuntu笔记本电脑通常仅通过无线连接到网络。 The screen refresh is choppy but usable. 屏幕刷新不稳定，但可用。
I've repeated the issue on a Win7 laptop which was connected via ethernet and wireless. 我在通过以太网和无线连接的Win7笔记本电脑上重复了该问题。
