起因

闲着没事，想在ubuntu上安装matlab。

步骤

这个博客写得很好，我就不赘述了：参考博客。但有点不一样：我现在matlab官网上下载的linux版本不是iso镜像文件，直接是一个zip压缩文件，不用什么挂载了。直接解压缩，然后再运行install文件。后面可以直接点击图标运行matlab。

问题

问题1

运行matlab会报错：

Gtk-Message: 15:46:15.337: Failed to load module "canberra-gtk-module"

这篇博客分析的很清楚：参考博客
执行这两步就行了：

sudo apt-get install libcanberra-gtk-module -y

sudo ln -s /usr/lib/x86_64-linux-gnu/gtk-2.0/modules/libcanberra-gtk-module.so /usr/lib/libcanberra-gtk-module.so

问题2

在matlab窗口中可以看到这样的提示：

com.jogamp.opengl.GLException: X11GLXDrawableFactory - Could not initialize shared resources for X11GraphicsDevice[type .x11, connection :0, unitID 0, handle 0x0, owner false, ResourceToolkitLock[obj 0x535b6672, isOwner false, <15a2f11f, 7c843551>[count 0, qsz 0, owner <NULL>]]]

也就是先这样启动matlab：
