 # Acer  # Generic laptop support
   
 ## Acer Aspire One 532h-2588  ## Graphics
   
 As of current in July 2010:  NetBSD 9.0 supports Intel integrated graphics up to Kaby Lake,
 Missing speedstep support (reed has patch for this).  Nvidia graphics up to Maxwell, and AMD graphics up to GCNv1.
 No ethernet (Atheros AR8132 PCI-E Fast Ethernet).  
 No wireless (Atheros AR9285 Wireless LAN 802.11 a/b/g/n).  
   
 ---  
   
 # Apple  
   
 ## iBook G3/600 with Radeon 7500 16MB VRAM  
   
 Used since NetBSD 1.6 or so.  
 Works nice with NetBSD/macppc.  
 No suspend support on NetBSD.  
 No modem support (some usb attached modem attaching as [[!template  
 id=man name="ugen" section="4"]].  
 No WPA on NetBSD with [[!template id=man name="wi" section="4"]] (in contrast  
 to Mac OS X).  
 NetBSD/5.1_STABLE has problem that keyboard doesn't  
 work in xdm after logout;  solved by forcing a xdm restart upon  
 logout.  
   
   Anything newer than this will work, but will use `llvmpipe`
   instead of hardware acceleration for OpenGL.
   
 ## MacBook Air 11 inch (mid 2012)  The support includes connecting external monitors over HDMI,
   DisplayPort, and DisplayPort over USB-C.
   
 NetBSD/amd64 6.99.11 works without some devices (for example, internal WiFi).  For the Intel driver, there may be slight graphical corruptions
 In detail, please see [[How to install NetBSD/amd64 current on MacBook Air 11 inch (mid 2012)|/users/ryoon/how_to_install_netbsd_amd64_to_macbook_air_11_inch]]  when using X11 without a compositor. Xfce/MATE include their own
   compositors, but lightweight window managers can benefit from
   having `picom` running.
   
   ## CPU frequency adjustment
   
 ---  On most ACPI and some non-ACPI laptops, the `sysutils/estd` package
   can be used to automatically adjust the CPU frequency depending on
 # Dell  system load, and potentially prolong battery life. This modifies the
   `frequency` variables exposed by
 ## Dell Latitude D610  [[!template id=man name="sysctl" section="8"]].
   
 NetBSD/i386 5.0.0.  ## Suspend
 Audio works (i82801FB (ICH6)).  
 Wireless with iwi (vendor 0x8086 product 0x4220).  
 For X11, using xf86-video-intel-2.2.1nb1 package.  
   
 ---  
   
 # Fujitsu  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"]].
   
 ## Fujitsu FMV-BIBLO LOOX P70WN  Suspend on NetBSD currently seems to work best on Thinkpads.
   
 NetBSD/i386 5.99.55.  ## Input
 Wireless with wpi works properly only when ACPI is disabled with "boot netbsd -2".  
   
 ---  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.
   
 # HP / Hewlett Packard  ## WiFi
   
 ## HP nc6120  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.
   
 5.1 did not have a working X.  See the
   [[!template id=man name="afterboot" section="8"]] man page for details
   on connecting to WiFi networks.
   
 Almost everything works with -current: sound, wireless, X11.  USB 11n WiFi adapters such as
 Did not try resume/suspend.  [[!template id=man name="urtwn" section="4"]] and
 Did not try the memory card slot recently.  [[!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"]].
   
 5.1 and -current have wired ethernet stability problems.  Unfortunately, WiFi hardware is not particularly standardized compared
 It gets watchdog timeouts and resets.  to most other aspects of modern laptops.
   
 X11 has a stability problem where a program can make total garbage on the  ## Audio
 screen (except the mouse pointer) and lock up the server. Repeatable with a  
 certain image viewer which shows very big images. The machine does not  
 freeze: power off button powers down smoothly, (but can not switch consoles to  
 try to kill the X server).  
   
 ## HP Pavilion laptop, dv9750  Essentially all modern x86 laptops use the 
   [[!template id=man name="hdaudio" section="4"]] driver.
   
 NetBSD 5.1, audio, webcam, Ethernet, kb/touchpad work fine.  In the case that switching between speakers and the headphone port
 Broadcom Wireless 4312 does not work.  is not handled automatically by the hardware, the `dacsel`
   [[!template id=man name="mixerctl" section="1"]] variable can be
   modified.
   
 ## HP ProBook 4310s  ## Sensors
   
 NetBSD i386 5.99.55  Regardless of whether the system is ACPI, NetBSD will

 # IBM / Lenovo  # IBM / Lenovo
   
 ## ThinkPad T22  The [[!template id=man name="thinkpad" section="4"]] driver provides
   support for various Thinkpad-specific sensors and function keys.
   
 Works perfect (sound, display, all devices, infrared port not tested).  A number of NetBSD developers use Thinkpads to hack on NetBSD
   and for everyday usage.
   
 ## ThinkPad T61  ## ThinkPad T22
   
 Used it since NetBSD 4.x.  Works perfect (sound, display, all devices, infrared port not tested).
 With Intel GMA, X works great.  
 In netbsd-5 there is a patch to make trackpoint/touchpad initialize correctly.  
 Requires  [[!template id=man name="hdaudio" section="4"]] instead  
 of  [[!template id=man name="azalia" section="4"]] to make headphones work.  
 Cardbus port doesn't work properly.  
 Expresscard not tested/tried.  
   
 ## Lenovo ThinkPad T61p  
   
 Following -current for the last 18 months or so (2012-12).  
 As close to perfect as one gets. Suspend/resume didn't work at the  
 time; not tried it since.  
   
 ## Lenovo ThinkPad T500  
   
 in the version with ATI graphics. Has a tendency to run hot and then to not  
 reboot cleanly (gets stuck after printing the mainbus line at boot);  
 5min off for cool-down usually fix this. This doesn't usually occur when  
 only the Intel on-board graphics get used. No known errors while running.

 ## Thinkpad X201  ## Thinkpad X220
   
   * 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

   * Ethernet is supported through the [[!template id=man name="wm" section="4"]] driver.
 ## Lenovo ThinkPad Edge E130  * WiFi is supported through the [[!template id=man name="iwm" section="4"]] driver.
   * Extra trackpoint buttons: run at least 9.0_STABLE for fixes to the Synaptics driver.
 With NetBSD/amd64 6.0  * Brightness buttons do not work in 9.0 by default. You can bind them to
     xrandr in your window manager.
 * Bluetooth adapter is recognized as ugen0 (should be patched like MacBook Air mid 2012 11-inch's one probably)  * Webcam will depend on upcoming xhci isochronous pipe support.
 * Native X.org needs xorg.conf that has vesa driver entry, and sometimes X.org starts with slightly wrong resolution (xrandr is useful).  * To record from the internal mic, set `mixerctl -w record.source=ADC02`
 * Sound is recognized as hdaudio, and not tested.  * Some spam from [[!template id=man name="hdaudio" section="4"]] on some 
 * Network adapters are not tested. Wired LAN adapter is detected as re0, and WiFi adapter is not recognized.    reboots, the chip doesn't seem to reset properly. Disappears and boots
 * Card reader is not recognized    normally after a few seconds.

   # 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)
   
   * Support for the display and HDMI output is provided through the Allwinner Display Engine driver.
     This provides kernel modesetting and a full-resolution video framebuffer, however,
     the 3D acceleration features of the GPU are not yet accessible - Mesa llvmpipe is used instead.
   * The CPU frequency can be adjusted automatically with `estd` or with `sysctl machdep.cpufreq.*`.
   * [[!template id=man name="uvideo" section="4"]] webcam works.
   * External WiFI adapters can be used. Support for the internal WiFi - after WiFi system rework?
   
   ## Pinebook Pro (Rockchip RK3399)
   
   * Support for the display output is provided through the Rockchip DRM driver.
     This provides kernel modesetting and a full-resolution video framebuffer, however,
     the 3D acceleration features of the GPU are not yet accessible - Mesa llvmpipe is used instead.
     Currently, you can't connect external displays through USB-C.
   * The CPU frequency can be adjusted automatically with `estd` or with `sysctl machdep.cpufreq.*`.
   * [[!template id=man name="uvideo" section="4"]] webcam works.
   * External WiFI adapters can be used. Support for the internal WiFi - after WiFi system rework?
     Internal Broadcom WiFi is supported via the [[!template id=man name="bwfm" section="4"]] driver in -current.
     However, external adapters may still be more stable.
   * The display backlight can be adjusted with `sysctl`.
   
   ### Pinebook Pro CPU affinity
   
   After setting `security.models.extensions.user_set_cpu_affinity=1` in `/etc/sysctl.conf`,
   you can run an intensive command on only the "big" CPUs:
   
   `$ schedctl -A 4,5 make package`
