This looks like a confused installation. The GPU is Intel, but you have an Nvidia driver installed, and an AMD kernel workaround on the command line.
But none of that should hurt... What will hurt is the unsupported "oibaf" packages you have replaced the official graphics drivers with. Sorry, but we cannot support such changes. Please remove the PPA from your system or just reinstall the OS without making any such changes. Then report new bugs for any issues you find. ** Package changed: xorg (Ubuntu) => ubuntu ** Changed in: ubuntu Status: New => Invalid -- You received this bug notification because you are a member of Ubuntu-X, which is subscribed to xorg in Ubuntu. https://bugs.launchpad.net/bugs/2062504 Title: Flickering problems on external monitor with HDMI after installing Ubuntu 23.10 To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+bug/2062504/+subscriptions _______________________________________________ Mailing list: https://launchpad.net/~ubuntu-x-swat Post to : ubuntu-x-swat@lists.launchpad.net Unsubscribe : https://launchpad.net/~ubuntu-x-swat More help : https://help.launchpad.net/ListHelp
