Ubuntu 18.04 still uses llvmpipe driver #2

I have an asus a15 laptop with an RTX2060 graphics card, and I am running Ubuntu 18.04. Despite following all the instructions here:

ubuntu 18.04 still uses llvmpipe driver

The llvmpipe driver is still being used.

Any help would be much appreciated.

You have a hybrid amd/nvidia graphics combo and the amd is primary and running llvm, so it’s missing the driver.
I guess it’s this:
For non-guessed info, please run nvidia-bug-report.sh as root and attach the resulting nvidia-bug-report.log.gz file to your post. You will have to rename the file ending to something else since the forum software doesn’t accept .gz files (nifty!).

Thank you, an upgrade to 20.04 fixed it.

I still only get 105 in glmark2 though, which is not what I expect.

Like said, you would have to provide a nvidia-bug-report.log for non-guessed info.

Here is a link to the log: https://drive.google.com/file/d/113SXZE459C0evUcMu_ou-3fsRjjSuxaG/view?usp=sharing

I’m not seeing a brightness control and the performance is definitely integrated graphics rather than the card I have.

(I am now running on ubuntu 20.04)

Hello, any chance you can help?
