Hi, I saw in this simmilar bug with other acer laptop model this solution:
https://bugs.launchpad.net/bugs/489041 ======================= I've just updated my /etc/default/grub with that option and the changed line its just like this: GRUB_CMDLINE_LINUX_DEFAULT="quiet splash nomodeset i8042.nomux acpi_backlight=vendor" Just to explain: - nomodeset: makes something show up in the screen (fix the videodriver) - i8042.nomux: makes the touchpad button work. - acpi_backlight=vendor: fix the brightness problem. Now just do the update-grub cmd. Remeber that this changes need root privilegies, so "sudo su" or "sudo <cmd>" ======================== I tried do the same thing on my karmic x32 on my acer 5732z and now when i use the fn keys there are more than 6 steps changing the brightness but nothing else, it is still not working. -- Cannot change brightness on laptop acer aspire 5732 Z https://bugs.launchpad.net/bugs/490610 You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. -- ubuntu-bugs mailing list [email protected] https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
