Original bug reporter here. After ~60 hours of testing I am confident the bug is resolved in 6.8.0-48.
With earlier Kernels 'intel_iommu=igfx_off' workaround still works as expected. I'll address reports of people still having issues. There are 3 possibilities: 1. The user failed to apply proper workaround. or install and activate proper kernel. The user must make sure: * The actual bootloader config file contains the 'intel_iommu=igfx_off' option and no other option related to GPU, CPU or power management. Those can disrupt the intended effect off all options * The actual kernel is running and no additional kernel options are enabled (use `uname -a` and `cat /proc/cmdline` commands to check). 2. The issue is not related to Intel Gen9 GPUs (6th-8th gen CPUs). You might have a different GPU/CPU, have discrete GPU in addition to integrated one. Please check if you GPU/GPUs are different open a new bug. 3. The flickering you are experiencing is not GPU related but caused by LCD panel refresh issue. This is entirely different issue which is not addressed by this bug. ** Tags removed: verification-needed-noble-linux ** Tags added: verification-done-noble-linux -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/2062951 Title: Random flickering with Intel i915 (Gen9 GPUs in 6th-8th gen CPUs) on Linux 6.8 To manage notifications about this bug go to: https://bugs.launchpad.net/linux/+bug/2062951/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
