synpatics, and the mtrack driver is not used at all.įor an MBP 8,3 I needed to use the following config (in /etc/X11//nf) to stop it picking up other input devices by mistake: Sometimes xorg loads other drivers before, like eg. Check if the mtrack module is properly loaded in the /var/log/Xorg.0.log file. The configuration is done via the /etc/X11//nf file. Mtrack is available in xf86-input-mtrack AUR. There are two drivers to provide features to the touchpad (including right and middle click): mtrack which is reported to work well and Synaptics which provides more features but might require some tuning. Unfortunately the right-click is not functional. Two finger scrolling and left-click works out of the box. See Kernel modules#Setting module options for more information. Set fnmode=2 parameters to hid_apple module. See Broadcom wireless for b43 installation and usage.ĭefault F1 key represents XF86MonBrightnessDown, if you want it represents to F1. Without this, you will get 'root fs not found' error.īoot into BIOS emulation mode.

Using rEFInd as a boot manager as an alternative to GRUB or systemd-boot is possible, but may need some configuration. In order to disable the the ATI Radeon graphics card. If, after installation, the screen freezes after boot, try booting with the kernel parameter If you want the changes to persist after installation, remember to install linux-headers and broadcom-wl-dkms during the pacstrap process (as well as iwd or a similar package to manage the connection after installation.)

You can then proceed to connect to the internet using iwctl. Try forcing a switch to the (non-free, but much more reliable) wl module by blacklisting any potentially interfering modules: rmmod b43 bcma ssb wl modprobe wl and then check if the wireless connection is now showing up when doing ip link.

As mentioned on Broadcom wireless#Installation, the BCM4331 chipset used on 8,2 has issues with the b43 module and if the bcma or bcma-pci-bridge is the module loaded, you need to switch it. In that case, check what kernel module is being used, by running lspci -v and look for the Network controller called BCM4331. Note: For 8,2 (potentially for 8,1 and 8,3 as well) be aware that you might find that ip link does not show the wireless network card.
