Graphics are Intel-powered, so you will need the [[Intel]] driver {{Pkg|xf86-video-intel}} for direct rendering.

Append the {{ic|1=acpi_backlight=video}} [[kernel parameter]].

To make [[fbsplash]] work, i915 has to be added to the modules array in mkinitcpio.conf:

{{Pkg|cpupower}} can be used for frequency scaling; see [[Cpufrequtils]] for more information. Undervolting is not possible with the Intel core iX cpu.
  
Add these kernel options to your bootloader's config file to make use of power saving mechanismens which are turned off by default because of reported instabilities. For me, they will work fine on the X201.

The Lenovo X201 is a dual-core subnotebook produced by Lenovo.

Device Working
Intel graphics Yes
Network Yes
Wireless Yes
ALSA Yes
Touchpad Yes
Bluetooth Yes
Webcam Yes
Card reader Yes
Power management Limited
Backlight Yes

Configuration

Backlight

Append the acpi_backlight=video kernel parameter.

Hibernation

See Power management/Suspend and hibernate#Hibernation.

Dock

See dockd.

Troubleshooting

Overheating

There are some discussions concerning overheating-related shutdowns when running under full load (video encoding, etc). [1] [2]

Use the following thinkfanAUR configuration [3]:

/etc/thinkfan.conf
#X201 user specific
#lvl    low     up      RPM
(0,    0,      47)     # 0
(1,    42,     57)     # 2000
(2,    44,     59)     # 3300
(3,    50,     65)     # 3500
(4,    54,     70)     # 3500
(5,    60,     73)     # 3800
(6,    62,     83)     # 3800
(7,    65,     88)     # 4300
(127,  70,     32767)  # 5300

cpupower can be used for frequency scaling; see Cpufrequtils for more information. Undervolting is not possible with the Intel core iX cpu.

No speaker output

Try pressing the mute button (next to the Escape key). See this article for details.

No ACPI events

See coreboot documentation: [4] [5]

Display issues

See Intel graphics#SNA issues and Intel graphics#DRI3 issues.

X201s: If planning to use VT-d, it is also recommended to add

intel_iommu=igfx_off

to the kernel parameters. see bug report.

Hardware virtualization

If KVM claims virtualization support is disabled in BIOS, even with VT-x enabled, disable Intel TXT. [6]
