Parameter author not defined. For correct usage see template's documention.
Input Devices
USB 3 Support
- Compile the xhci-hcd driver as module.
Kernel configurationUSB controller: Fresco Logic Device 1009 (rev 02), 3.3.1-gentoo
Device Drivers --->
[*] USB support --->
<M> xHCI HCD (USB 3.0) support (EXPERIMENTAL)
N.B. A kernel version 3.3 at least is required for the USB 3 support.
Drives and Storage
- Hard Drive controller works using ahci driver in the kernel.
Kernel configurationIntel Corporation 6 Series/C200 Series Chipset Family 6 port SATA AHCI Controller, 3.3.1-gentoo
Device Drivers --->
<*> Serial ATA and Parallel ATA drivers --->
<*> AHCI SATA support

<*> /dev/agpgart (AGP Support) --->
<*> Intel 440LX/BX/GX, I8xx and E7x05 chipset support
<*> Direct Rendering Manager (XFree86 4.1.0 and higher DRI support) --->
<*> Intel 8xx/9xx/G3x/G4x/HD Graphics
[*] Enable modesetting on intel by default
There is an issue with screen brightness which cannot be adjustable. It is possible to workaround it with the following command:
root # echo 0 > /sys/class/backlight/intel_backlight/brightnessUse a script to run it at start up.
File/etc/local.d/backlight.start
#!/bin/bash echo 0 > /sys/class/backlight/intel_backlight/brightness
As well as after hibernate and suspend.
File/etc/pm/sleep.d/backlight
#!/bin/bash
case "$1" in
suspend|hibernate)
#do nothing
;;
resume|thaw)
echo 0 > /sys/class/backlight/intel_backlight/brightness
;;
*)
exit 1
;;
esac
exit 0
Both scripts need to be executable.
root # chmod +x /etc/local.d/backlight.start /etc/pm/sleep.d/backlightWLAN Card

Bluetooth
Not tested.
Problems
Noisy fan
On the core i7 model, the fan is running too often and too early. A bios upgrade resolved the issue. http://www.dell.com/support/drivers/us/en/19/DriverDetails/DriverFileFormats?DriverId=C0VG5&FileId=2902722114&productCode=xps-13-l321x&urlProductCode=False
Touchpad
The TouchPad is based on a Cypress firmware and doesn't seem to have good opensource driver (I couldn't get the tap and multi-touch to work yet). Two patches were submitted in 2011 by Cypress developers to fix it but there were not yet accepted into the kernel mainline:
- http://thread.gmane.org/gmane.linux.kernel/1108661
- http://groups.google.com/group/linux.kernel/browse_thread/thread/5aeb1dd1559d9ab9?pli=1
There's also a ticket opened on the Ubuntu launchpad:
