Thanks for confirmation! Mainline kernels are not really meant for production environment, however fix should be already available in 7.0.0-31.31 Ubuntu kernel via -proposed repository. I think right now there are 4 options available for you.
1. Wait till end of month until kernel 31 gets to regular update channel. 2. Enable -proposed repository and get 7.0.0-31 kernel update through it (instruction: https://wiki.ubuntu.com/Testing/EnableProposed) right now. 3. Stay with mainline v7.1-rc7 for now until you get an update via apt to 7.0.0-31 (but probably it is going to be the least stable option). 4. I've seen a workaround via boot parameter in one of threads related to this issue, which can be used with 7.0.0-29 to make brightness control work again until update to 31 lands. ** Changed in: linux (Ubuntu) Status: Confirmed => Fix Committed -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/2163249 Title: [i915] Internal display extremely dim despite max backlight, unrelated to DE/kernel version (WhiskeyLake UHD 620) To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/linux/+bug/2163249/+subscriptions -- ubuntu-bugs mailing list [email protected] https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
