Tagging of X bugs

Kernel Graphics Issues

• kernel-handoff-graphics - Issues forwarded to kernel from X
• kernel-needs-review - Needs review by a kernel team member
• kernel-candidate - Has been reviewed by a subject matter expert, needs review for inclusion in top list
• kernel-graphics-vga - Bugs pertaining to VGA graphics
• kernel-graphics-resolution - Bugs pertaining to video resolution issues
• kernel-graphics-blankscreen - Bugs pertaining to blank screen resume/reboot
• kernel-graphics-hdmi - Bugs pertaining to HDMI video out
• kernel-hotkey - Bugs related to hotkey/buttons not working

Symptom classification

• error-exit - X exits with error code and error message

• no-screens - X exits because no usable screen configuration could be determined

• crash - X process terminates with backtrace / SIGSEGV

• freeze - Can ssh into the machine, mouse cursor moves, but is otherwise hung / locked up / stuck in a loop

• corruption - Screen shows garbage or mis-rendered graphics

• tearing - a phenomenon in video where a newly rendered frame overlaps a previously rendered frame, creating a torn look as two parts of an object.

• kernel-graphics-resolution or userspace-resolution (Was resolution) - X starts with an incorrectly selected resolution, does not provide access to full range of expected resolutions, or fails in switching to alternate resolution

• performance - game fps is low, or perceived graphics display speed is below expectations

• flicker - X blinks or flickers continuously or temporarily after startup, resume, etc.

• dual-head - problem setting up external monitor, mirrored or extended

• backlight - on laptop, screen's illumination does not work properly

• videoplayback - problem associated with playing video, such as using Xv

• ghost-monitor - the video driver seems to be configuring around a non-existent output device

• edid - problem associated with EDID interpretation, often resulting in incorrect resolution detection

• 3d - issue relating to 3D behavior

• compiz - problem involving compiz functionality

• resume - issue that occurs following a resume from suspend or hibernation

• cropped - screen is only partially displayed

• font-size - fonts are way too big or way too small, usually because of incorrect EDID

• kernel-graphics-blankscreen - screen goes completely black/blank on boot, or after suspend/resume, or during regular usage (Was black-screen)

• vt-switch - problem occurs during or after switching virtual terminals (ctrl-alt-f#)

• tv-out - issue associated with the TV/HDMI/S-Video output

• high-cpu - problem is associated with higher than expected CPU usage

• pointer - problem relates to the display or behavior of the mouse pointer

• error-message - a confusing or endlessly repeating error message

• touch - issue with touch support in applications or X

• user-switching - problem is associated to or triggered by user-switching

Hardware

-ati driver

r100, r200, r300, r400, r500, r600, r700 and rs690 (taken from http://wiki.x.org/wiki/RadeonProgram).

-intel driver

Short names of the intel chipsets. Usually simplifed versions of the chipset variable in src/intel_module.c of the intel driver. This is printed in Xorg.0.log. Chipset PCI-ID is also printed in Xorg.0.log and there is a list in src/intel_driver.h. Wikipedia has a nice table that shows how each graphics core (GPU) relates to its chipset.
