Exact hardware model

Acer Aspire (TimelineX) 3830TG

Core i5-2410M 2.3GHz


NVIDIA GeForce GT 540M

750 GB HDD

Atheros wifi (AR9287) b/g/n

(Probably some of these issues only for Arch Linux, e.g. on Ubuntu handling automatically, (Ubuntu is great, but too fat for me) )

Really issues, hardware problems

Sound card issue

There is no sound, however snd modules loaded on kernel. (I am working on it. There are some workaround...)

Screen backlight issue

Add kernel option acpi_osi=Linux


  • Edit /boot/grub/menu.lst
  • Find your system menu entry, and add acpi_osi=Linux kernel option

Mine menu entry looks like:

title  Arch Linux
root   (hd0,6)
kernel /boot/vmlinuz-linux root=/dev/sda7 ro acpi_osi=Linux
initrd /boot/initramfs-linux.img
  • reboot and pray

Note: tested with integrated Intel GPU only

But still an issue that I cannot set brightness value from software (from sysfs), only Fn + Left/Right arrows working.

GPU switch issue

At the moment I turned NVIDIA GPU off from BIOS, later I will provide some info about switching. Until then you can check on Bumblebee

Lighter issues


Fn + buttons

ACPI events
