Hey everyone, I've just found a workaround for this problem somewhere deep in the waters of Internet. For me and my Asus UL20A it worked like a charm, so hopefully, it may be useful to some of the others here.
1) open /etc/default/grub 2) add "acpi_backlight=vendor acpi_osi=linux" to GRUB_CMDLINE_LINUX 3) run sudo update-grub 4) restart your computer -- can't adjust the brightness of my laptop display https://bugs.launchpad.net/bugs/570042 You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
