# X.Org Server ## Identification [[X.Org Server|X.Org]], `fbdev`, [[evdev|evdev]], and XInput form a Linux graphical/input stack. A Xen guest may expose a virtual pointer in addition to a passed-through or host-integrated mouse, causing duplicate or conflicting devices. [[inxi|inxi]] inventories hardware and system configuration. ## Notebook evidence - [[Scanned_20260730-1719#PDF page 70 — X.Org input-driver troubleshooting in a Xen guest|PDF page 70: X.Org input-driver troubleshooting in a Xen guest]] — This is a concrete troubleshooting page: a SysVinit guest reaches runlevel 5, loads a basic framebuffer driver, and then needs an X.Org rule to ignore an unwanted Xen virtual pointer while retaining the physical Mionix mouse. ## Relationships and overlays The source places this note in a shared evidence cluster with [[evdev|evdev]] · [[inxi|inxi]]. Within the larger collection, this evidence extends [[Vendor-Agnostic Recovery|vendor-agnostic recovery]] and [[Continuity Architecture|continuity architecture]] by showing how software, hardware, identity, and pre-OS control depend on recoverable interfaces. ## Evidentiary status and open leads Preserve `xinput list`, `/var/log/Xorg.0.log`, device match properties, and the final tested rule. ## Source - [[Scanned_20260730-1719|Scanned_20260730-1719]] ## Scanned_20260730-1659 overlay **Source evidence:** [[Scanned_20260730-1659#PDF page 44 — XQuartz, freedesktop.org, Arch Linux, and Oh My Zsh|page 44]]. [[XQuartz|XQuartz]] brings the X.Org X11 display system to macOS; freedesktop.org standardizes Linux desktop interoperability. Parrot OS is security-oriented Linux; Arch Linux is a rolling-release distribution; DiskMaker X creates macOS installers; Oh My Zsh configures the [[Z shell|Z shell]]; iTerm2 is a macOS terminal. `appcourse.com` and the United Airlines fragment remain unresolved. **Relationship overlay:** [[Arch Linux|Arch Linux]] · [[DiskMaker X|DiskMaker X]] · [[freedesktop.org|freedesktop.org]] · [[iTerm2|iTerm2]] · [[Oh My Zsh|Oh My Zsh]] · [[Parrot OS|Parrot OS]] · [[XQuartz|XQuartz]] · [[Z shell|Z shell]]. This evidence supplements rather than replaces earlier notebook interpretations.
