Hi,
I just installed Linux Mint 20.1 on my computer (ThinkPad P51 with Nvidia Quadro 2200m).
I have issues regarding Matlab and also regarding the detecting the GPU.
After I boot my computer, I open the terminal and launch Matlab using the command
MATLAB$
然后Matlab打开，但这出现在终端中：
libGLerror: MESA-LOADER: failed to open iris (search paths /usr/lib/x86_64-linux-gnu/dri:\$${ORIGIN}/dri:/usr/lib/dri)
libGLerror: failed to load driver: iris
libGLerror: MESA-LOADER: failed to open iris (search paths /usr/lib/x86_64-linux-gnu/dri:\$${ORIGIN}/dri:/usr/lib/dri)
libGLerror: failed to load driver: iris
libGLerror: MESA-LOADER: failed to open swrast (search paths /usr/lib/x86_64-linux-gnu/dri:\$${ORIGIN}/dri:/usr/lib/dri)
libGLerror: failed to load driver: swrast
libGLerror: MESA-LOADER: failed to open iris (search paths /usr/lib/x86_64-linux-gnu/dri:\$${ORIGIN}/dri:/usr/lib/dri)
libGLerror: failed to load driver: iris
libGLerror: MESA-LOADER: failed to open iris (search paths /usr/lib/x86_64-linux-gnu/dri:\$${ORIGIN}/dri:/usr/lib/dri)
libGLerror: failed to load driver: iris
libGLerror: MESA-LOADER: failed to open swrast (search paths /usr/lib/x86_64-linux-gnu/dri:\$${ORIGIN}/dri:/usr/lib/dri)
libGLerror: failed to load driver: swrast
在MATLAB的命令行窗口中，显示此消息：
com.jogamp.opengl.GLException: X11GLXDrawableFactory - Could not初始化X11GraphicsDevice的共享资源[类型.x11，连接：0，unitid 0，handle 0x0，所有者false，resourcetoolkitlock [obj 0x12660792，isoneer false，<4555ae5c1，28f5776a>

/home/adrien/matlabdesktopcreateerror.log
我发现我需要在终端中运行以下内容，以使此消息消失：
exportmesa_loader_driver_override = i965
Then I launch Matlab again and check if it is using the dedicated GPU of my computer:
>> gpudevice
错误using gpuDevice (line 26)
Unableto find a supported GPU device. For more information on GPU support, see释放的G万博1manbetxPU支持。
Is there anything I can do to solve this issue?
Also, if I reboot the computer, the initial error comes back and I need to
exportmesa_loader_driver_override = i965
again in order to make the first error message disappear.
Thank you for your help.
