HP Envy 4t UltrabookTM
Work in progress. Post any suggestions here.
This page is a work in progress. This describes the issues I've had while trying to run Gentoo Linux on the Ultrabook. Some sparse Gentoo specific information is located at the bottom of this page.


This machine theoretically should have all hardware supported by Linux though it's a fairly new machine to the market. As this is an "Ultrabook" and there's no option for having only an SSD installed, this machine has Intel Smart Response Technology. Unfortunately though the hardware is supported, the software is not. I had to remove SRT and install a full SSD into the machine. I currently use a 128GB Crucial M4 SSD.

Sound

The machine uses Intel HD Audio hardware, which Alsa uses the snd_intelhd driver. It works out of the box.

Ethernet

Realtek RTL8111/8168B Gigabit Ethernet (r8169) - Ethernet is a Realtek 8169 derivative Gigabit Ethernet using using the r8169 driver. Modern Linux should support this out of the box.

Wireless

My machine has the Intel's Centrino 802.11b/g/n internal wireless card. The in-kernel drivers work (iwlagn - Intel Wire Less A/G/N?) driver works with it. With Gentoo I still needed to grab and put iwlwifi-2030-6.ucode into /lib/firmware for it to work. It should be in sys-kernel/linux-firmware (but not sys-firmware/iwl5000-ucode ?)...

Pointer

The Alps touchpad pointer appears as a regular PS/2 device and is synaptics compliant. It has two buttons that are embedded within the touch surface. You can't do Emulate3Buttons and I have yet to find a way to use the middle button click. It supports two-finger scrolling.

Display

My HP Envy4t has CPU graphics. It has an Intel Core i5-3317U Ivybridge CPU/GPU attached to a 16x9 14.1" 1366x768 SXGA+ display, which is supported by the opensource drivers in X.Org's X11 drivers. It worked pretty flawlessly once the correct kernel was installed, except the problem of the screen being blacked out (backlight fails to turn on) during boot. This is most likely due to a firmware issue. A Fn-F3 will brighten the blacked out display. Multiple bugs were submitted to freedesktop to track them, but it's trending towards a firmware bug that needs to be worked around. Multiple HP laptops have the exact same issue.

The workaround I accidently found while trying to learn about the issue is to put a 1ms or so delay in the screen brightness routines. The 43577 bug on freedesktop has the location I found to make this problem "go away" so that I can see the bootup sequence without touching Fn-F3 immediately after the screen goes dark.

Another workaround is to specify that it should not trust BIOS brightness.

Power Saving

The Envy 4t has ACPI hardware and this should be enabled in the kernel config. It does support speedstep and will change CPU frequency on the fly.
I have not been able to get it reliably S3 suspend, it seems to want to do a hybrid suspend somehow (ACPI?). S4 is also somewhat broken. Still trying to figure out why.
