Many PC-BSD® users successfully run PC-BSD® on their laptops. However, depending upon the model of laptop, you may run across some issues. These typically deal with:

  • Sleep/suspend: unfortunately, ACPI[1] is not an exact science, meaning that you may have to experiment with various sysctl variables in order to achieve successful sleep and suspend states on your particular laptop model. A BIOS setting of suspend state[2] S1 can lead to a system freeze. If your laptop is a ThinkPad, Thinkwiki[3] is an excellent source. For other types of laptops, try reading the SYSCTL VARIABLES section of man 4 acpi and check to see if there is an ACPI man page specific to your vendor by typing apropos acpi. The Tuning with sysctl(8)[4] section of the FreeBSD Handbook demonstrates how to determine your current sysctl values, modify a value, and make a modified value persist after a reboot. If the battery reading is incorrect, try the workaround in this PR[5].
  • Internal wireless: some chipsets do not have a FreeBSD driver yet.
  • Synaptics: depending upon the hardware, you may or may not be able to disable the system's touchpad. This forum post[6] describes how to enable Synaptics and some of the sysctl options that this feature provides.
  • Optimus graphics: the current workaround is to disable Optimus in the BIOS, set the onboard Intel video to be dominant, or to change the graphics mode to discrete.

If you wish to test your laptop's hardware, use the Hardware Compatibility icon in the first screen of the installer before continuing with the installation.

If you would like to install PC-BSD® onto an Asus Eee, read the FreeBSD Eee page[7] first.

The FreeBSD Tuning Power Consumption page[8] has some tips for reducing power consumption.

[edit] Bekannte Fehler bei ThinkPads

The ThinkPad T420 may panic during install. If it does, go into the BIOS and set the video mode to "discrete" which should allow you to complete an installation.

Some Thinkpads have a BIOS bug that prevents them from booting from GPT labelled disks. If you are unable to boot into a new installation, restart the installer and go into Advanced Mode in the Laufwerkauswahl. Make sure that the "Partition disk with GPT" box is unchecked. If it was checked previously, redo the installation with the box unchecked.

[edit] Touchscreens

PC-BSD® should automatically detect USB-based touch screen devices. If your display is USB and is not auto-detected, send the output of usbconfig and your /etc/X11/xorg.conf file tusing the [[PC-BSD® Bug Reporting/10.1/de|Translations:PC-BSD® Bug Reporting/10.1/Page display title/de]] tool.
