Public bug reported: When waking the system from suspension, the screen turns black and flickers repeatedly for a minute, until it gets back to normal.
This issue is closely related to this other bug: https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1958191 Indeed, the black-screen flickering affected also booting, but adding the kernel parameters suggested in the link (`i915.enable_dc=0 intel_idle.max_cstate=2`) solved that at least for boot. I'm on Linux Mint 21.3 (i.e. Ubuntu 22.04) with 6.5 kernel. I tried other kernels (5.4, 5.15) and drivers (545, 470, 390, Nouveau), but nothing changed. This issue didn't happen on Focal 20.04. Running `ubuntu-bug linux` gives me a PermissionError(13, 'Permission denied'). * Kernel: 6.5.0-35-generic x86_64 * Intel Core i7-7700HQ * Intel HD Graphics 630 driver: i915 v: kernel * NVIDIA GP107M [GeForce GTX 1050 Mobile] driver: nvidia v: 535.171.04 * Display: x11 server: X.Org v: 1.21.1.4 ** Affects: linux (Ubuntu) Importance: Undecided Status: New -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/2069163 Title: Black screen flickering on resume [22.04] [i915] To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/linux/+bug/2069163/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
