Hi, OK I have tried both temporary and permanent grub boot changes with modified intel_idle.max_cstate=2 and 4 and on all occasions after grub update and reboot the boot splash page is steady the login page flickers badly and the desktop settles but still flickers.
Tks for the help but unfortunately workaround does not work on the Dell Insperion 955 Intel i7 64/16Gb 1tb Radeon GPU. Ive include a snap shot of my patched grub boot file. ** Attachment added: "GrubIdlePatch.png" https://bugs.launchpad.net/ubuntu/+source/linux/+bug/2062951/+attachment/5781539/+files/GrubIdlePatch.png -- 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 on Linux 6.8 (Ubuntu 24.04) To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/linux/+bug/2062951/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
