@Aaron, @David, It looks BIOS for P15/P17 Gen1 N30ET45W(1.28) is released to LVFS already. R510 NV driver with this BIOS can resolve this issue. https://fwupd.org/lvfs/devices/com.lenovo.ThinkPadN30ET.firmware -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1944435 Title: Backlight on P17 Gen 1 not working Nvidia 470 To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1944435/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs

Aaron, I'm not sure if R510 NV driver can fix this or not. Sorry, we cannot find this system panel combination on hand, could you help to check this on your end?

Thanks Aaron, Customer noted that this didn't help him - but I assume the above only helps in hybrid mode. Customer is quite grumpy...but David is on PTO and he has the system for reproducing so I'm just trying to manage expectations at the moment. Let me know if there are any other suggestions.

Please use "i915.enable_dpcd_backlight=0" for WA, or use 5.13.0-1012-oem kernel instead. I will try to fix it in hirsute kernel. ** Changed in: linux (Ubuntu) Assignee: (unassigned) => AaronMa (mapengyu) -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1944435 Title: Backlight on P17 Gen 1 not working Nvidia 470 To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1944435/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
