GNOME First Steps
What is GNOME?
"GNOME 3 is an easy and elegant way to use your computer. It is designed to put you in control and bring freedom to everybody. GNOME 3 is developed by the GNOME community, a diverse, international group of contributors that is supported by an independent, non-profit foundation." GNOME
Before installing GNOME, ensure that the X Window System has been installed.
Please note that Linux kernel 3.15.* may still have serious incompatibility with various graphics drivers. If you like to use gentoo-sources or vanilla-sources, please use a 3.14.* kernel. This is of particular importance if you plan to run GNOME, and want to use NVIDIA (commercial or nouveau) or ATI (ati-drivers) graphics drivers.
Preparing to emerge
To get your system ready to emerge gnome, it is recommended that you first set the gnome profile mix-in. To accomplish this, do the following:
# eselect profile list Currently available mix-ins profiles:  funtoo/1.0/linux-gnu/mix-ins/audio  funtoo/1.0/linux-gnu/mix-ins/console-extras  funtoo/1.0/linux-gnu/mix-ins/dvd  funtoo/1.0/linux-gnu/mix-ins/gnome  funtoo/1.0/linux-gnu/mix-ins/kde  funtoo/1.0/linux-gnu/mix-ins/mate  funtoo/1.0/linux-gnu/mix-ins/media  funtoo/1.0/linux-gnu/mix-ins/print  funtoo/1.0/linux-gnu/mix-ins/python3-only  funtoo/1.0/linux-gnu/mix-ins/rhel5-compat  funtoo/1.0/linux-gnu/mix-ins/server-db  funtoo/1.0/linux-gnu/mix-ins/server-mail  funtoo/1.0/linux-gnu/mix-ins/server-web  funtoo/1.0/linux-gnu/mix-ins/X  funtoo/1.0/linux-gnu/mix-ins/xfce  funtoo/1.0/linux-gnu/mix-ins/vmware-guest  funtoo/1.0/linux-gnu/mix-ins/hardened
After seeing a list of available profiles, we want to add in the appropriate number for the gnome mix-in. To do this, run the following:
# eselect profile add 14
By enabling the gnome mix-in, various USE and other settings will be optimized to provide you with a pain-free GNOME installation experience.
You are provided with two packages that will pull in this desktop environment:
This is the "whole shabang" - pulls in a range of applications made for the gnome desktop environment including a few games, an archive manager, a system monitor, a web browser, a terminal, etc.
As the name implies, this pulls in the base minimal you need to get a functioning GNOME Desktop Environment.
GNOME 3.12 from a clean install
To emerge gnome run the following command
# emerge gnome
To emerge gnome-light run the following command
# emerge -va gnome-light
Upgrading from GNOME 3.6
To emerge gnome, remove nautilus-open-terminal if it is installed as it now bundled into gnome-terminal
# emerge -vaC nautilus-open-terminal
Then, run the following command
# emerge -vauDN world
To emerge gnome-light remove the following packages as there have been changes since 3.6 (you will have up reinstall any packages that have been renamed after gnome-light completes).
# emerge -vaC gnome-fallback gnome-panel gnome-screensaver metacity gnome-games gcalctool nautilus-open-terminal
Then, run the following command
# emerge -vauDN world
Finally, restore any applications that have been renamed (such as gcalctool => gnome-calculator)
# emerge -va gnome-calculator
For bluetooth support, ensure that:
- Bluetooth support is enabled in your kernel (using modules is fine).
- Your bluetooth hardware is turned on.
- Add the
bluetoothstartup script to the default runlevel, and start it.
This can be done as follows:
# rc-update add bluetooth default # rc
Once this is done, you should now be able to navigate to Settings -> Bluetooth and turn bluetooth on. The icon next to devices should now animate and you should be able to discover and add devices such as keyboards.
To enable printing support, add
cupsd to the default runlevel:
# rc-update add cupsd default # rc
You should now be able to navigate to Settings -> Printers and add printers to your system, and print.
To enable scanning support, add your user account to the
lp group. This will allow your user to access the USB scanner.
emerge xsane, and run it. It should be able to access your scanner.
Setting up xdm (GUI log-in)
Typically, you will want to use gdm, the GNOME display manager, to log in to GNOME. This will allow you to log in graphically, rather than using the text console.
To enable gdm, edit /etc/conf.d/xdm and set DISPLAYMANAGER to gdm instead of xdm. Then, perform the following steps to add xdm to the default runlevel, and have it start automatically from now on when your system starts:
# rc-update add xdm default
Then, if you want to start it now do
But you should reboot to avoid having an open login terminal
Setting up xinitrc (text log-in)
Adding the following to your ~/.xinitrc file is sufficient:
# Fix Missing Applications in Gnome export XDG_MENU_PREFIX=gnome- # Properly Launch the Desired X Session exec ck-launch-session gnome-session
Additionaly, if you need support for different input sources, there is no longer a need to configure ibus or scrim in your .xinitrc file as GNOME uses ibus natively. Simply configure it in the Control Center under Region & Langauge.
Disable Adwaita Dark Theme
If you do not like the Adwaita Dark Theme it can be disabled by copying then modifying it like so:
mkdir -p ~/.themes/Adwaita-NoDark cp -r /usr/share/themes/Adwaita/gtk-* ~/.themes/Adwaita-NoDarkhttp://www.funtoo.org/Category:Ebuild_Category rm ~/.themes/Adwaita-NoDark/gtk-3.0/gtk-dark.css ln -s gtk.css ~/.themes/Adwaita-NoDark/gtk-3.0/gtk-dark.css
Then, run gnome-tweak-tool and select select Theme -> GTK+ Theme -> Adwaita-NoDark.
If you run GUI programs with the sudo command, then the above steps (excluding running gnome-tweak-tool) must be repeated for the root account.
Verify the inode/directory MimeType Handler
In some odd instances, baobab might take priority over nautilus when handling the inode/directory MimeType. If this behavior is not desired, add the following to /home/~/.local/share/applications/mimeapps.list:
[Added Associations] inode/directory=nautilus.desktop;baobab.desktop;
Automatically Starting Applications at Login
When using an old-fashioned .xinitrc, starting up applications when X starts is relatively easy. When using GDM, this can still be accomplished, by using the ~/.xprofile file. Here's my sample .xprofile to start xflux to dim the screen at night:
xflux -z 87107
Remember to add a & at the end of any command that doesn't return to the shell prompt after running.
