How can I fix that?

Hi, your driver version should be fine. Can you please show the output of the following commands?

lsb_release -a

xrandr

Are you running on Ubuntu 18.04 and with a display monitor?

Thank you. That looks ok.

The only other thing that could be an issue is your kernel version. Here’s the default kernel and xorg version for Ubuntu 18.04:

ubuntu@ip-172-31-30-213:~$ cat /proc/version
Linux version 5.4.0-1048-aws (buildd@lcy01-amd64-026) (gcc version 7.5.0 (Ubuntu 7.5.0-3ubuntu1~18.04)) #50~18.04.1-Ubuntu SMP Tue May 4 17:40:02 UTC 2021
ubuntu@ip-172-31-30-213:~$ apt-cache show xserver-xorg | grep Version
Version: 1:7.7+19ubuntu7.1
Version: 1:7.7+19ubuntu7

Is it possible to try downgrade your kernel to this version if yours is a later version?

This is my version, how do I downgrade that?

giangnguyen@ai-00028:~$ cat /proc/version
Linux version 4.15.0-151-generic (buildd@lgw01-amd64-042) (gcc version 7.5.0 (Ubuntu 7.5.0-3ubuntu1~18.04)) #157-Ubuntu SMP Fri Jul 9 23:07:57 UTC 2021
giangnguyen@ai-00028:~$ apt-cache show xserver-xorg | grep Version
Version: 1:7.7+19ubuntu7.1
Version: 1:7.7+19ubuntu7

After updating my ubuntu, the error disappeared, so the problem is solved.
