 # Dell  ---
   
 ## Dell Latitude D610  # Generic laptop support
   
 NetBSD/i386 5.0.0.  ## Graphics
 Audio works (i82801FB (ICH6)).  
 Wireless with iwi (vendor 0x8086 product 0x4220).  
 For X11, using xf86-video-intel-2.2.1nb1 package.  
   
 # Toshiba  NetBSD 9.0 supports Intel integrated graphics up to Kaby Lake,
   Nvidia graphics up to Maxwell, and AMD graphics up to GCNv1.
   
 ## Toshiba Satellite A215-S7422  Anything newer than this will work, but will use `llvmpipe`
   instead of hardware acceleration for OpenGL.

 See <http://gnats.netbsd.org/39275>.  
 Audio works with hdaudio (vendor 0x10EC product 0x0268).  
   
 ## Toshiba Satellite L350-S1701  On most ACPI and some non-ACPI laptops, the `sysutils/estd` package
   can be used to automatically adjust the CPU frequency depending on
   system load, and potentially prolong battery life. This modifies the
   `frequency` variables exposed by
   [[!template id=man name="sysctl" section="8"]].
   
 NetBSD/amd64 5.99.38.  ## Suspend
 Wireless with iwn (vendor 0x8086 product 0x4232).  
 For X11, using xf86-video-vesa-2.3.0nb1 package.  On ACPI systems, suspend-to-RAM is supported through
 The MMC works on sd0.  `sysctl hw.acpi.sleep.state=3`.  This can be triggered through various

   [[!template id=man name="powerd" section="8"]].
   
   Suspend on NetBSD currently seems to work best on Thinkpads.
   
   ## Input
   
   Many x86 laptops use Synaptics touchpads over an emulated PS/2 interface,
   which is supported through [[!template id=man name="pms" section="4"]],
   with various adjustable sysctl variables.
   
   ## WiFi
   
   Many x86 laptops with Intel processors will have WiFi cards supported
   by the
   [[!template id=man name="iwm" section="4"]] driver, or 
   [[!template id=man name="iwn" section="4"]] for older models.
   Atheros 11n miniPCIe cards are supported by the
   [[!template id=man name="athn" section="4"]] driver.
   
   See the
   [[!template id=man name="afterboot" section="8"]] man page for details
   on connecting to a WPA network.  For connecting to a non-WPA network,
   simply specify `ssid networkname up` in 
   [[!template id=man name="ifconfig" section="8"]], and make sure
   [[!template id=man name="dhcpcd" section="8"]] is running.
   
   USB WiFI adapters such as
   [[!template id=man name="urtwn" section="4"]] and
   [[!template id=man name="run" section="4"]] can also be used,
   and most/all generic USB ethernet adapters are also well supported.
   For a fairly complete list, see 
   [[!template id=man name="usb" section="4"]].
   
   ## Audio
   
   Most modern x86 laptops use the 
   [[!template id=man name="hdaudio" section="4"]] driver.
   
   In the case that switching between speakers and the headphone port
   is not handled automatically by the hardware, the `dacsel`
   [[!template id=man name="mixerctl" section="1"]] variable can be
   modified.
   
   ---
   
   # IBM / Lenovo
   
   The [[!template id=man name="thinkpad" section="4"]] driver provides
   support for various Thinkpad-specific sensors and function keys.
   
   ## ThinkPad T22
   
   Works perfect (sound, display, all devices, infrared port not tested).
   
   ## ThinkPad T61
   
   Used it since NetBSD 4.x.
   With Intel GMA, X works great.
   Cardbus port doesn't work properly.
   Expresscard not tested/tried.
   
   ## ThinkPad X60s
   
   Everything works.
   
   ## ThinkPad X41
   
   Works fine (sound, display, all devices, bluetooth, modem not tested).
   Standby is broken for me in -current (~2012-01-12) but worked in 5.1.
   
   ## ThinkPad X61s
   
   Everything works. Requires `PCI_BUS_FIXUP` and `PCI_ADDR_FIXUP` [[!template
   id=man name="options" section="4"]].
   
   ## Thinkpad X201
   
   Running -current since March 2011.
   Working graphics (with the vesa driver), audio, trackpoint, wired
   and wireless LAN.
   Does not wake up after suspend (drives spin up but the display
   stays black and the LED indicating a sleep state stays lit).
   
   ## Thinkpad X220
   
   From user reports, in NetBSD 9.0:
   
   * Video acceleration works, but when using `xf86-video-intel` (the default),
     it's advisable to set `Option "AccelMethod"  "uxa"` in `xorg.conf`.
   * Ethernet is supported through the [[!template id=man name="wm" section="4"]] driver.
   * WiFi is supported through the [[!template id=man name="iwn" section="4"]] driver.
   * Suspend and resume work.
   
   ## Thinkpad X230
   
   From user reports, in NetBSD 9.0:
   
   * Ethernet is supported through the [[!template id=man name="wm" section="4"]] driver.
   * WiFi is supported through the [[!template id=man name="iwn" section="4"]] driver.
   
   ## Thinkpad X250
   
   Nearly perfect. Running NetBSD 9.0 and -current since 2019.
   
   * Accelerated graphics with the i915 driver. Connecting externals displays
     works with the miniDP and VGA ports.
   * SD card reader is supported through the [[!template id=man name="rtsx" section="4"]] driver.
   * Ethernet is supported through the [[!template id=man name="wm" section="4"]] driver.
   * WiFi is supported through the [[!template id=man name="iwm" section="4"]] driver.
   * For the extra trackpoint buttons to work correctly, needs a patch to
     synaptics.c that is in -current and will be in 9.1.
     Tapping and the clickpad have always been fine.
   * Brightness buttons do not work in 9 by default. You can bind them to
     xrandr in your window manager.
   * Webcam will depend on upcoming xhci isochronous pipe support.
   * To record from the internal mic, set `mixerctl -w record.source=ADC02`
   * Wakes up after suspend. I have mine set to suspend on lid close with
     powerd.
   
   ## Thinkpad X260
   
   Likely very similar to the X250.
   
   From user reports, in NetBSD 9.0:
   
   * SD card reader is supported through the [[!template id=man name="rtsx" section="4"]] driver.
   * Ethernet is supported through the [[!template id=man name="wm" section="4"]] driver.
   * WiFi is supported through the [[!template id=man name="iwm" section="4"]] driver.
   * For the extra trackpoint buttons to work correctly, needs a patch to
     synaptics.c that is in -current and will be in 9.1.
     Tapping and the clickpad have always been fine.

   # PINE64
   
   ## Pinebook (Allwinner A64)
   
   The Pinebook does not use ACPI so certain aspects are different
   compared to x86 laptops.
   
   From user reports to port-arm@, in NetBSD 9.0:
   
   * [[!template id=man name="uvideo" section="4"]] webcam works.
   * External WiFI adapters can be used. Support for the internal WiFi - after WiFi system rework?
   * Plugging in external monitors works via the HDMI port.
   * The CPU frequency can be adjusted with `sysctl machdep.cpufreq.*`.
   * Mesa llvmpipe is currently used for 3D/OpenGL.
   
   ## Pinebook Pro
   
   The Pinebook Pro does not use ACPI so certain aspects are different
   compared to x86 laptops.
   
   * [[!template id=man name="uvideo" section="4"]] webcam works.
   * Internal Broadcom WiFi is supported via the [[!template id=man name="bwfm" section="4"]] driver in 9_STABLE.
     External adapters may still be more stable.
   * The CPU frequency can be adjusted automatically with `estd` or with `sysctl machdep.cpufreq.*`.
   * The display backlight can be adjusted with `sysctl`.
   * Mesa llvmpipe is currently used for 3D/OpenGL.
