Thanks for the bug report. I can see two main problems here: 1. The amdgpu kernel graphics driver is emitting warnings that look like crashes. 2. The rtw_8821ce kernel wifi driver is flooding the system log (this is probably the performance issue).
So I can only suggest trying an older Ubuntu release like 22.04.0 with an older kernel: https://old-releases.ubuntu.com/releases/jammy/ubuntu-22.04-desktop- amd64.iso or trying newer kernels from: https://kernel.ubuntu.com/mainline/?C=M;O=D or replace the wifi card in the laptop with an Intel one. ** Summary changed: - awful performance + [RTL8821CE] awful performance ** Package changed: xorg (Ubuntu) => linux (Ubuntu) -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/2077920 Title: [RTL8821CE] awful performance To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/linux/+bug/2077920/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
