A workstation has been fitted with a new graphics card and you must pin the X server to a specific driver by hand in /etc/X11/xorg.conf. In which section of that file does the Driver line for the card belong?
LPIC-1 Exam 102-500, objective 106. User interfaces and desktops medium
Machine-checked — no person has signed for it. This question was read against the source cited below by an automated pass, which found no contradiction. That is a weaker claim than it sounds: the same kind of process wrote the question, so it can confirm its own mistake.
Treat it as a good draft rather than as settled fact, and read the source below before you rely on it. It is not used in mock exams here — only questions a person has signed for are.
How these questions are written — where each question comes from, what the verification ledger records, and what happens when one is found wrong.
The options
Not correct Section "Monitor"
Wrong. A Monitor section describes the display panel itself — its identifier, and legacy timing hints such as HorizSync, VertRefresh and Modeline entries. It says nothing about which kernel or Xorg driver talks to the card.
Correct Section "Device"
Correct. A Device section describes one piece of graphics hardware. It carries Identifier, the Driver line naming the Xorg video driver (intel, amdgpu, nouveau, modesetting, nvidia) and optionally BusID to pick between several cards.
Not correct Section "Screen"
Wrong. A Screen section binds one Device to one Monitor and holds the Display subsections that set colour Depth and the list of Modes. It references a Device by identifier rather than configuring one.
Not correct Section "ServerLayout"
Wrong. ServerLayout is the top of the tree: it names which Screens and which InputDevices make up the running server, and how several screens are positioned relative to each other.
Why
xorg.conf is a set of named sections that reference each other by Identifier, and the containment runs ServerLayout -> Screen -> Device plus Monitor, with InputDevice and InputClass alongside. Hardware goes in Device, the panel goes in Monitor, and the pairing plus resolution and depth goes in Screen. Modern systems usually ship no xorg.conf at all and are tuned with a single-purpose snippet dropped into /etc/X11/xorg.conf.d/, which uses exactly the same section syntax.
