# Configuration

This article is based on HP Envy 14 2090eo (LS782EA) model. Wireless chip might be different on other regions.

## CPU

Works out of the box. See [CPU frequency scaling](/index.php/CPU_frequency_scaling "CPU frequency scaling") for more information on power saving. Both cpufrequtils and cpupower work. Latter is recommended for additional features.

## Video

This laptop has two graphics chips, one on the CPU and the other AMD Radeon 6630M with dedicated 1 GB RAM.

**Note:** that the screen goes black after booting because the backlight is disabled by default. Increase back light using shift-fn-f3 key combination. After installing add command `w /sys/class/backlight/acpi_video0/brightness - - - - 1` to `/etc/tmpfiles.d/local.conf` for turning the back light on automatically.

### Intel

After enabling using vga_swictheroo works perfectly. No Xorg configuration needed.

### AMD
