Your screen backlight is usually a completely separate device and kernel driver from the graphics driver. Have a look in: /sys/class/backlight/ for details and low-level controls.
Also read: https://wiki.ubuntu.com/Kernel/Debugging/Backlight So this is not a valid cedarview-drm-drivers bug. But if you find which package is at fault causing your backlight problem, you can add it to this bug. ** Changed in: cedarview-drm-drivers (Ubuntu) Status: New => Invalid -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1188446 Title: i dont see any noticable problems except not being able to adjust the screen brightness To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/cedarview-drm-drivers/+bug/1188446/+subscriptions -- ubuntu-bugs mailing list [email protected] https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
