 # 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.
   
 NetBSD/amd64 5.99.38, but booting with "boot netbsd -2" to disable ACPI  The support includes connecting external monitors over HDMI,
 but has no keyboard use.  DisplayPort, and DisplayPort over USB-C.
 See <http://gnats.netbsd.org/39275>.  
 Audio works with hdaudio (vendor 0x10EC product 0x0268).  
   
 ## Toshiba Satellite L350-S1701  For the Intel driver, there may be slight graphical corruptions
   when using X11 without a compositor. Xfce/MATE include their own
   compositors, but lightweight window managers can benefit from
   having `picom` running.
   
 NetBSD/amd64 5.99.38.  ## CPU frequency adjustment
 Wireless with iwn (vendor 0x8086 product 0x4232).  
 For X11, using xf86-video-vesa-2.3.0nb1 package.  On most ACPI and some non-ACPI laptops, the `sysutils/estd` package
 The MMC works on sd0.  can be used to automatically adjust the CPU frequency depending on
 Sometimes USB failures. Sometimes X starts up on wrong resolution.  system load, and potentially prolong battery life. This modifies the
   `frequency` variables exposed by
   [[!template id=man name="sysctl" section="8"]].
   
   ## Suspend
   
   On ACPI systems, suspend-to-RAM is supported through
   `sysctl hw.acpi.sleep.state=3`.  This can be triggered through various
   events (such as lid close) with
   [[!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 Synaptics-specific 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 WiFi networks.
   
   USB 11n 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"]].
   
   Unfortunately, WiFi hardware is not particularly standardized compared
   to most other aspects of modern laptops.
   
   ## Audio
   
   Essentially all 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.
   
   ## Sensors
   
   Regardless of whether the system is ACPI, NetBSD will
   expose all sensors (e.g. for temperature and battery)
   via [[!template id=man name="envstat" section="8"]].
   
   ---
   
   # IBM / Lenovo
   
   The [[!template id=man name="thinkpad" section="4"]] driver provides
   support for various Thinkpad-specific sensors and function keys.
   
   A number of NetBSD developers use Thinkpads to hack on NetBSD
   and for everyday usage.
   
   ## 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:
   
   * Accelerated graphics with the i915 driver.
   * 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`
   * Suspend and resume work.
   
   ## Thinkpad X260
   
   From user reports, in NetBSD 9.0:
   
   * Accelerated graphics with the i915 driver.
   * 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.
   * Suspend and resume work.

   # PINE64
   
   A number of NetBSD developers use Pinebooks to hack on NetBSD
   and for everyday usage.
   
   Pinebook and Pinebook Pro do not use ACPI, so certain aspects are
   different compared to x86 laptops.
   
   ## Pinebook (Allwinner A64)
   
   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
   
   * [[!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 -current.
     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.
   * Connecting external monitors does not currently work through USB-C.
