Where is xorg config

The most common conditions are:. Create for each graphics card a Device section. An example Device section looks like this:. Create for each monitor a Monitor section.

An example Monitor section looks like this:. For input devices override the configuration of xorg. Note Manually creating xorg.

Oh, by the way, man xorg. It removed my second monitor from my PC. No easy fix for that one, so I guess I have to reinstall ubuntu. Nice one. Simon seriously? Did you try to just undo what you did? Read desgua's answer, it explains how the newly created xorg. You can generate one pretty easily though: sudo Xorg -configure. This works fine for me with Nvidia Optimus Bumblebee without any special configuration, just the defaults:!

For lost amd users: Please note that amd drivers provide a tool to generate xorg. Adrian Lopez Adrian Lopez 1 1 gold badge 4 4 silver badges 12 12 bronze badges.

This needs the package xorg-server-xnest to be installed. With the help of xinput you can temporarily disable or enable input sources.

This might be useful, for example, on systems that have more than one mouse, such as the ThinkPads and you would rather use just one to avoid unwanted mouse clicks.

Install the xorg-xinput package. Disable the device with xinput --disable device , where device is the device ID or name of the device you want to disable. In this example we will disable the Synaptics Touchpad, with the ID Deps: xorg-xprop , xdotool.

To prevent a user from killing when it is running add the following to xorg. Xorg may run with standard user privileges instead of root so-called "rootless" Xorg. This is a significant security improvement over running as root. Note that most display managers do not support rootless Xorg. See also Xorg. To configure rootless Xorg using xinitrc :.

GDM will run Xorg without root privileges by default when kernel mode setting is used. However, the stdout and stderr output from the Xorg session is not redirected to this log. To re-enable redirection, start Xorg with the -keeptty flag and redirect the stdout and stderr output to a file:. See [4]. GDM users should check the systemd journal. The logfiles are of the form Xorg.

For a single user machine with default configuration the applicable log is frequently Xorg. To make sure to pick the right file it may help to look at the timestamp of the X server session start and from which console it was started. For example:. X creates configuration and temporary files in current user's home directory.

Make sure there is free disk space available on the partition your home directory resides in. Unfortunately, X server does not provide any more obvious information about lack of disk space in this case.

To correct, uninstall the xfvideo-fbdev package. Some programs only work with bitmap fonts. Two major packages with bitmap fonts are available, xorg-fontsdpi and xorg-fontsdpi. You do not need both; one should be enough. To find out which one would be better in your case, try xdpyinfo from xorg-xdpyinfo , like this:. Modeline — An optional parameter which specifies additional video modes for the monitor at particular resolutions, with certain horizontal sync and vertical refresh resolutions.

Refer to the xorg. Each Device section configures one video card on the system. While one Device section is the minimum, additional instances may occur for each video card installed on the machine.

The best way to configure a video card is to configure X during the installation process or by using the X Configuration Tool.

The following example illustrates a typical Device section for a video card:. Identifier — Specifies a unique name for this Device section. Driver — Specifies which driver the X server must load to utilize the video card. VendorName — An optional parameter which specifies the vendor of the video card. BoardName — An optional parameter which specifies the name of the video card. VideoRam — An optional parameter which specifies the amount of RAM available on the video card in kilobytes.

This setting is only necessary for video cards the X server cannot probe to detect the amount of video RAM.

BusID — An entry which specifies the bus location of the video card. On systems with more than one video card, however, a BusID entry must be present. Screen — An optional entry which specifies which monitor connector or head on the video card the Device section configures.

This option is only useful for video cards with multiple heads. If multiple monitors are connected to different heads on the same video card, separate Device sections must exist and each of these sections must have a different Screen value. Values for the Screen entry must be an integer. The first head on the video card has a value of 0. The value for each additional head increments this value by one. Each Screen section binds one video card or video card head to one monitor by referencing the Device section and the Monitor section for each.

While one Screen section is the minimum, additional instances may occur for each video card and monitor combination present on the machine. Identifier — Specifies a unique name for this Screen section. Device — Specifies the unique name of a Device section. Monitor — Specifies the unique name of a Monitor section.
