This bug affects me too on Dell Inspiron 7000 Gaming series with Intel 7700HQ and nvidia 1050ti.
The brightness controls do not work. One additional property in the bug or could be a separate bug -> after resume from suspend, the built-in display has no backlight, I can faintly see some graphics or connect an external display and see the GUI, however, after a single suspend -> resume cycle, the built-in display backlight DOES NOT switch-on no matter what, mandatorily requires a reboot to get the back-light back. ---------- Buggy version: Linux 7.0.0-28-generic Last functional version: Linux 7.0.0-27-generic -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/2161359 Title: linux-modules-7.0.0-28-generic breaks backlight control on some laptops To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/linux/+bug/2161359/+subscriptions -- ubuntu-bugs mailing list [email protected] https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
