## Issues

### ACPI and Intel KMS

Screen goes black when Intel KMS[broken link: invalid section] and ACPI is on. Brightness controls are not working.

Solution: Add the following to your kernel parameter list:

     acpi_osi=Linux acpi_backlight=vendor

Alternate solution (as those parameters break some fn keys):

- With `acpi_osi=Linux` or both - mute, wireless and sleep keys do not work.
- With `acpi_backlight=vendor`, brightness is not shifted, but control is totally disabled and brightness does not restore to max when AC power is restored.

So instead (as seen here):

    # setpci -s 00:02.0 f4.b=ff

Where "00:02.0" is PCI address of video card (as reported by `lspci`). This shifts up min and max brightness levels on hardware level, without affecting anything in `/sys/class/backlight/...` or `/proc/acpi/video/VGA/LCDD/...`

Using `acpi_backlight=vendor` and changing `f4.b` register simultaneously will result in even brighter, blinding maximum backlight, while used separately the effect is roughly equal.

### LCD Brightness

See Backlight.

If brightness levels are erratic, download the latest BIOS from Asus

If maximum brightness seems lower than it should be, see setpci solution above.

### Network Adapter

Problem: The network adapter for wired LAN does not or rarely get recognized (`lspci` and `ip addr` do not list it).

Solution: Add the following to your kernel parameter list:

     eeepc_laptop.hotplug_disabled=1

### Touchpad

See Touchpad Synaptics.

Two-Finger scrolling works with a `/etc/X11/xorg.conf` like this:
