Linux Xorg Settings
When using AskLink on certain Linux distributions (such as Ubuntu, Debian, Fedora, CentOS, Arch, Manjaro, or openSUSE), you may encounter issues like a black screen, failed connections, or abnormal input.
These problems are often caused by your system running a Wayland session.
It’s recommended to switch to an Xorg (X11) session for a more stable remote control experience.
This guide only covers how to switch sessions through the graphical user interface (GUI) — no command line operations are required.
- The session must be changed on the login screen (before entering your password).
Doing this on the lock screen will not work. - If your system is set to log in automatically, log out first to return to the login screen.
- While the interface may vary slightly across distributions, the key step is the same:
Select an Xorg / X11 session at the login screen → then log in.
For systems that use the GDM login manager with a gear icon on the login screen:
- On the login screen, click your username.
- When the password field appears, click the gear icon near the bottom or next to the password box.
- From the dropdown menu, select:
- Ubuntu on Xorg (for Ubuntu), or
- GNOME on Xorg (for other GNOME-based systems), or
- Any option containing “X11” or “Xorg”.
- Enter your password to log in.
- Try using AskLink again after logging in.

For systems that use the SDDM login manager with a Session button at the bottom or corner of the screen:
- On the login screen, click the Session button.
- In the list, choose Plasma (X11) or KDE Plasma (X11).
- Enter your password to log in.
- After logging in, use AskLink for remote access.
For systems that use the LightDM login manager with a Session / Desktop switch menu:
- On the login screen, locate the Session / Desktop menu (usually a small icon or dropdown at the top or side).
- Choose the session that matches your desktop environment, preferring those without “Wayland” in the name, for example:
- Enter your password to log in.
Most LightDM-based desktops already use Xorg by default.
As long as you don’t explicitly select a “Wayland” session, no extra configuration is needed.
