Set up Wi-Fi:
sudo apt-get install bcmwl-kernel-source
sudo modprobe wl
in the file /etc/modules, add the line
wl
in order to start up the wireless service upon reboot.
It might be necessary to edit /etc/modprobe.d/blacklist.conf and uncomment the lines that blacklist bcm43xx.
Use
lspci -nn | grep 0280
to check the type of your Wi-Fi hardware; it should be:
02:00.0 Network controller [0280]: Broadcom Corporation BCM4360 802.11ac Wireless Network Adapter [14e4:43a0] (rev 03)
For the NVidia driver to work with X, install
sudo apt-get install nvidia-current
(use the NVidia X Server Settings app to configure it.)
In System Preferences -> Displays: set "Scale for menu and title bars" to 2
Use Chromium-Browser (NOT vanilla Chrome) for browsing: it respects high-DPI Retina display and looks normal (image isn't shrunk by a factor of 4...)
Install gnome-tweak-tool, use it to re-bind CAPS LOCK key to Control (for use with Emacs)
Install compiz-config-tool, use it to disable annoying Unity/Launcher keyboard combinations (especially Super=Windows=Command combinations). Here, also use the opportunity to use Cmd+Tab (Super+Tab) for switching between applications instead of the default Alt+Tab.
In Terminal: Edit -> Keyboard Shortcuts: uncheck "Enable menu access keys" to make Alt work normally (as the Meta key), [not only] in Emacs (instead of messing with the annoying menu bar.)
add the line
alias e='emacs -nw'
in ~/.bashrc (-nw is needed to start Emacs in command-line mode)
