@Hui Wang I followed your instructions, installed the test kernel and removed i915.enable_psr=0 from grub.
The performance is slightly better than on default Ubuntu 24.04, but the mouse pointer still jumps around and the in-built display is still laggy/unresponsive. I would still say it is unusable without adding i915.enable_psr=0 to grub. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/2065096 Title: [i915] Display is Laggy/Unresponsive when PSR is enabled To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/linux/+bug/2065096/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
