can't get eGPU working on Ubuntu20.04 ( Aorus GTX 2080TI Gaming Box )

[tpzou]

Hi,

I recently purchased an external GPU, specifically the GIGABYTE Aorus GTX 2080ti Gaming Box to use with my laptop, I have a Dell G5 RTX2060 running Ubuntu 20.04. And my egpu can be authorized but can’t be used.

I try to reinstall the nvidia driver to suit both of gpu, but it is helpless. Everything seems to be normal, but the nvidia-smi can't recognize the egpu and I can't use it....

Can anyone help me? Thanks.

Have you only executed the config command? You should run egpu-switcher setup rather than egpu-switcher config. The config command only configures egpu-switcher (ie. saves your inputs), only the setup command will then actually create the necessary xorg configurations.

Thanks for your reply, I have run egpu-switcher setup. I run egpu-switcher config, because whenI rerun it, itprompted me that I should do this again,

Have you actually verified that the GPU isn't being used? If not, what is the output of glxinfo | grep "OpenGL renderer string"? Could you also provide the output of lspci -D -d ::0300 && lspci -D -d ::0302 and cat /etc/X11/xorg.conf.egpu. Both of would be helpful in debugging your problem, yet I fear we may not be able to help you if it is a driver related issue.
