Solved How to add monitor section to xorg. Thread starter Handy92 Start date Feb 20, Handy92 Active Member Reaction score: 12 Messages: I want to configure screen resolution and orientation of second monitor.

I add section response for external monitor: Code:. It doesn't use xorg. That doesn't seem right, because they are using different types of terms. When no value is specified, the option's value is TRUE. The following boolean option values are recognised as TRUE :.

Frequency option values consist of a real number that is optionally followed by one of the following frequency units:. When the unit name is omitted, the correct units will be determined from the value and the expectations of the appropriate range of the value. It is recommended that the units always be specified when using frequency option values to avoid any errors in determining the value. The Files section is used to specify some path names required by the server.

Some of these paths can also be set from the command line see Xserver 1 and Xorg 1. The command line settings override the values specified in the config file. The Files section is optional, as are all of the entries that may appear in it. This path is a comma separated list of font path elements which the Xorg server searches for font databases. Multiple FontPath entries may be specified, and they will be concatenated to build up the fontpath used by the server.

Font path elements can be absolute directory paths, catalogue directories or a font server identifier. The formats of the later two are explained below:. Catalogue directories can be specified using the prefix catalogue: before the directory name. The directory can then be populated with symlinks pointing to the real font directories, using the following syntax in the symlink name:. When this entry is not specified in the config file, the server falls back to the compiled-in default font path, which contains the following font path elements which can be set inside a catalogue directory :.

Font path elements that are found to be invalid are removed from the font path when the server starts up. This path is a comma separated list of directories which the Xorg server searches for loadable modules loading in the order specified.

Multiple ModulePath entries may be specified, and they will be concatenated to build the module search path used by the server. The default module path is. The -xkbdir command line option can be used to override this. The default directory is. In addition to options specific to this section described below , the ServerFlags section is used to specify some global Xorg server options.

All of the entries in this section are Options , although for compatibility purposes some of the old style entries are still recognised. Those old style entries are not documented here, and using them is discouraged.

The ServerFlags section is optional, as are the entries that may be specified in it. Options specified in this section with the exception of the "DefaultServerLayout" Option may be overridden by Options specified in the active ServerLayout section. Options with command line equivalents are overridden when their command line equivalent is used.

The options recognised by this section are:. This comma-separated list provides a way to control various debugging switches from the config file. This specifies the default ServerLayout section to use in the absence of the -layout command line option. This prevents the Xorg server from trapping a range of unexpected fatal signals and exiting cleanly. Instead, the Xorg server will die and drop core where the fault occurred. The default behaviour is for the Xorg server to exit cleanly, but still drop a core file.

In general you never want to use this option unless you are debugging an Xorg server problem and know how to deal with the consequences. That sequence is normally used to switch to another "virtual terminal" on operating systems that have this feature. When this option is enabled, that key sequence has no special meaning and is passed to clients.

Default: off. This action is normally used to terminate the Xorg server. When this option is enabled, the action has no effect. These sequences allows you to switch between video modes. When this option is enabled, those key sequences have no special meaning and are passed to clients.

This disables the parts of the VidMode extension used by the xvidtune client that can be used to change the video modes. Default: the VidMode extension is enabled. This allows the xvidtune client and other clients that use the VidMode extension to connect from another host. It has no effect on the evdev 4 or other drivers. Default: false. This is equivalent to the Xorg server's -s flag, and the value can be changed at run-time with xset 1. Default: 10 minutes.

Set the maximum number of clients allowed to connect to the X server. Acceptable values are 64, , or Disables something to do with power management events. Default: PM enabled on platforms that support it.

Include the default font path even if other paths are specified in xorg. If enabled, other font paths are included as well. Enabled by default. Allow modules built for a different, potentially incompatible version of the X server to load. Disabled by default. If this option is disabled, then no devices will be added from the HAL or udev backends. If this option is disabled, then the devices will be added and the DevicePresenceNotify event sent , but not enabled, thus leaving policy up to the client.

If this option is disabled, then no GPU devices will be added from the udev backend. May need to be disabled to setup Xinerama. If enabled then secondary GPUs will be automatically set up as output-sinks and offload-sources. Making e. Possible values are flush or sync. Unset by default. The Module section is used to specify which Xorg server modules should be loaded. This section is ignored when the Xorg server is built in static form.

The type of modules normally loaded in this section are Xorg server extension modules. Most other module types are loaded automatically when they are needed via other mechanisms.

The Module section is optional, as are all of the entries that may be specified in it. Entries in this section may be in two forms. The first and most commonly used form is an entry that uses the Load keyword, as described here:. This instructs the server to load the module called modulename.

The module name given should be the module's standard name, not the module file name. This instructs the server to not load the module called modulename. Some modules are loaded by default in the server, and this overrides that default. If a Load instruction is given for the same module, it overrides the Disable instruction and the module is loaded. As with the Load instruction, the standard name is case-sensitive, and does not include the "lib" prefix, or the ".

The second form of entry is a SubSection, with the subsection name being the module name, and the contents of the SubSection being Options that are passed to the module when it is loaded. Example: the extmod module which contains a miscellaneous group of server extensions can be loaded, with the XFreeDGA extension disabled by using the following entry:.

Modules are searched for in each directory specified in the ModulePath search path, and in the drivers, extensions, input, internal, and multimedia subdirectories of each of those directories. In addition to this, operating system specific subdirectories of all the above are searched first if they exist. The Extensions section is used to specify which X11 protocol extensions should be enabled or disabled. The Extensions section is optional, as are all of the entries that may be specified in it.

Entries in this section are listed as Option statements with the name of the extension as the first argument, and a boolean value as the second.

The extension name is case-sensitive, and matches the form shown in the output of "Xorg -extension? The config file may have multiple InputDevice sections. Recent X servers employ HAL or udev backends for input device enumeration and input hotplugging.

It is usually not necessary to provide InputDevice sections in the xorg. AutoAddDevices is enabled. If hotplugging is enabled, InputDevice sections using the mouse, kbd and vmmouse driver will be ignored.

If hotplugging is disabled, there will normally be at least two: one for the core primary keyboard and one for the core pointer.

If either of these two is missing, a default configuration for the missing ones will be used. In the absence of an explicitly specified core input device, the first InputDevice marked as CorePointer or CoreKeyboard is used. The final fallback is to use built-in default configurations.

Currently the default configuration may not work as expected on all platforms. The Identifier and Driver entries are required in all InputDevice sections. All other entries are optional. The Identifier entry specifies the unique name for this input device. The Driver entry specifies the name of the driver to use for this input device. When using the loadable server, the input driver module " inputdriver " will be loaded for each active InputDevice section.

An InputDevice section is considered active if it is referenced by an active ServerLayout section, if it is referenced by the -keyboard or -pointer command line options, or if it is selected implicitly as the core pointer or keyboard device in the absence of such explicit references. The most commonly used input drivers are evdev 4 on Linux systems, and kbd 4 and mousedrv 4 on other platforms.

InputDevice sections recognise some driver-independent Options , which are described here. See the individual input driver manual pages for a description of the device-specific options. Always add the device to the ServerLayout section used by this instance of the server. When enabled, the input device is set up floating and does not report events through any master device or control a cursor. This option is disabled by default. SendCoreEvents "on" is equivalent to Floating "off". This option controls the startup behavior only, a device may be reattached or set floating at runtime.

Specifies the 3x3 transformation matrix for absolute input devices. The input device will be bound to the area given in the matrix. In most configurations, "a" and "e" specify the width and height of the area the device is bound to, and "c" and "f" specify the x and y offset of the area.

The value range is 0 to 1, where 1 represents the width or height of all root windows together, 0. The values represent a 3x3 matrix, with the first, second and third group of three values representing the first, second and third row of the matrix, respectively. The identity matrix is "1 0 0 0 1 0 0 0 1".

For pointing devices, the following options control how the pointer is accelerated or decelerated with respect to physical device motion. Most of these can be adjusted at runtime, see the xinput 1 man page for details. This is an iframe, to view it upgrade your browser or enable iframe display.

The xorg. When a change occurred with the monitor, video card or other device managed by the X server, the file needed to be edited manually. Nevertheless, it is still useful to understand various sections and optional parameters available, especially when troubleshooting or setting up unusual hardware configuration.

More detailed information about the X server configuration file can be found in the xorg. This section is mostly intended for advanced users as most configuration options described below are not needed in typical configuration scenarios. The InputClass section. InputClass is a new type of configuration section that does not apply to a single device but rather to a class of devices, including hot-plugged devices.

An InputClass section's scope is limited by the matches specified; in order to apply to an input device, all matches must apply to the device as seen in the example below:.

If this snippet is present in an xorg. Alphanumeric sorting in xorg. Note that due to alphanumeric sorting of configuration files in the xorg. The more generic the class, the earlier it should be listed.

The match options specify which devices a section may apply to. To match a device, all match options must correspond. The following options are commonly used in the InputClass section:. Refer to the fnmatch 3 man page for further details. A configuration file may have multiple InputClass sections. These sections are optional and are used to configure a class of input devices as they are automatically added. An input device can match more than one InputClass section.

When arranging these sections, it is recommended to put generic matches above specific ones because each input class can override settings from a previous one if an overlap occurs. The InputDevice section. Each InputDevice section configures one input device for the X server. Previously, systems typically had at least one InputDevice section for the keyboard, and most mouse settings were automatically detected. The default driver for both keyboards and mice is evdev.

The following example shows a typical InputDevice section for a keyboard:. The following entries are commonly used in the InputDevice section:. Identifier — Specifies a unique name for this InputDevice section. This is a required entry. Driver — Specifies the name of the device driver X must load for the device. If the AutoAddDevices option is enabled which is the default setting , any input device section with Driver "mouse" or Driver "kbd" will be ignored.

Monitor menus also doesn't come up when I press the buttons. In the past it doesn't worked well but when GUI was loaded the LG monitor took the signal and it switched itself on somehow.

Right now it simply refuses to work. Ok, so the main problem is that your display manager is using the wrong resolution, right? You can put an xrandr command in your xinitrc to select the x mode. Which display manager: I am using Xfce. And I have a process called "lxdm. If I not kill the lxdm. But unfortunatelly instead of 60 Hz, 61 Hz is set sixty-one Hz and monitor doesn't support that well, I get a distorted picture on the screen.

If you do not have the tech sheet for the monitor, you can interactively search the proper values and a modeline using xorg-xvidtune. Atom topic feed.
