The display manager is available to multiple users. Xrandr -output DVI-I-1 -primary -mode 1600x900 -rate 59.98 -output VGA-1 -mode 1280x1024 -rate 75.02 -right-of DVI-I-1Īlternatively, root can start a display manager such as kdm, lightdm gdm, gdm3 or xdm. Screen layout and settings can be set with a xrandr command. The user session can be configured by the content of ~/.xsessionrc. Rather than in nf, another quite useful way to adjust X settings is on the fly, in a desktop environment's list of scripts to run at startup.Īfter installation a user can create an X session with startx, a front end to xinit. Xorg reads vendor configuration information from the directory /usr/share/X11/, as stated by man. Per this comment and this advice, it seems best to create the directory /etc/X11/ and place in it a few files in order to tweak sections of the implicit nf, as for example is done here. Question: what should be done if generating this file fails, giving the message, 'Number of created screens does not match the number of detected devices'?Īnyway, probably, this is unnecessary. This should give you something to work with. # /etc/init.d/gdm stop || /etc/init.d/gdm3 stop || /etc/init.d/kdm stop || /etc/init.d/xdm stop || /etc/init.d/lightdm stopĪlternatively, reboot the machine in single user mode, then run:įollow the on-screen instructions. Switch to a console as root ( not a terminal emulator in X), then run: To create a starting point for customization, do the following. Though this works fine in most cases, some settings remain inaccessible. If nf is missing for some reason, Xorg will probe your hardware on every startup. What if I do not have a xorg config file? Open a terminal (or console) as root, then run : # editor /etc/X11/nf Some settings are only accessible through editing nf by hand. To reconfigure keyboard settings in Squeeze (and later) run as root in a terminal: # dpkg-reconfigure keyboard-configuration Where xxx is to be replaced by the name of your video driver. If you wish to have a proper graphic session starter, you should consider running $ sudo apt install xserver-xorg-video-xxx xserver-xorg-core xinit Note that with the latter you won't have the startx command (provided by bin:xinit but if you install it directly it'll pull all video drivers) and therefore will have troubles to start any graphical display. Or for just the X11 server itself without drivers and utilities: $ sudo apt install xserver-xorg-core Installing Xorg is simple as: $ sudo apt install xorg Also, anything after the dash ( -2) is the Debian packaging version. Reminder: Debian package version sometimes starts with a digit followed by a column, like 1:7.3.1-2. The module's version may be different (The maintainers sometimes cherry-pick more recent and stable modules). If you want to learn more about Xorg releases/versions, see this blog.ĭebian version number follows upstream convention. For instance, Xorg 7.3 was shipped with Xserver version v1.4, xf86-input-evdev v1.1.5, xf86-video-intel v2.1.1, etc. This release is composed of various modules which have their own version number (each module started at version "1.0" when Xorg 7.0 development cycle started). Nowadays, Xorg is released with a version number (like 7.4). Xorg version numbering has changed since xorg 7.0. The current versions shipped in Debian are listed on : xorg, xserver-xorg-core.
