报错分析

从报错信息上看是openGL的报错 program not linked 应该是缺个库，所以打算吧openGL的包重新都安装一下，

解决

安装openGL的库

sudo apt-get install build-essential
sudo apt-get install build-essential libgl1-mesa-dev
sudo apt-get install libglew-dev libsdl2-dev libsdl2-image-dev libglm-dev libfreetype6-dev
sudo apt-get install libglfw3-dev libglfw3

安装完之后，可以在重新连接试试

注意

连接远程桌面时，不要使用 root 和 ubuntu 用户登录，必须新创建一个用户进行登录，这个似乎时gnome桌面的bug或者也可能是基于安全方面的考虑？
