Xorg radeon driver documentation

Some window managers e. For other window managers, a standalone composite manager can be used. This article or section needs expansion. See also Clipboard Tools and an overview of X automation tools. 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:. This may happen if you have previously run Xorg as root e. That error means that only the current user has access to the X server. The solution is to give access to root:. Then, this problem may be caused by systemd issue Set up early KMS start.

If you have a laptop that's getting too hot, try setting the power management profile to low. Since it's closed-source, only AMD can work on it and give efficient support, and the open-source community can generally not help you with problems. Partners Support Community Ubuntu.
