Hi, Thanks for filing a bug report. Currently the kernel is tainted by nvidia modules, to rule them out can you boot with `module_blacklist=nvidia,nvidia_modeset,nvidia_uvm` added to your boot args? Similarly, can you try adding `i915.enable_psr=0` to your boot args?
I noticed this line in your logs: i915 0000:00:02.0: [drm] [ENCODER:515:DDI B/PHY B] unusable PPS, disabling eDP PPS here is 'panel power sequencing', which could be related to backlight flicker. Nothing concrete though. Can you capture some more debug info while the screen flickers: echo 0x1e | sudo tee /sys/module/drm/parameters/debug sudo dmesg --follow-new > ~/dmesg-flicker.txt Then use your machine until you get some flickering, then you can ctrl+c the terminal and upload dmesg-flicker.txt here. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/2170396 Title: Lenovo Legion screen flickering on Kubuntu 26.04 (Fixed by lowering brightness / 165Hz conflict) To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/linux/+bug/2170396/+subscriptions -- ubuntu-bugs mailing list [email protected] https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
