Score Comparison Plot:

The following plot shows how this terminal’s scores compare to all other terminals tested.

../_images/konsole_scores_scaled.png — Scaled scores comparison across all metrics (normalized 0-100%)

Final Scaled Score Calculation:

Raw Final Score: 77.15% (weighted average: WIDE + NARROW + ZWJ + LANG + VS16 + 0.33 * SRI + 0.33 * SFZ + RI + CAP + 0.5 * GFX + 0.5 * RSC) the categorized ‘average’ absolute support level of this terminal.

Note

RSC (Resources) is a composite CPU, memory, and runtime score. RSC is weighted at 0.5 (half as powerful as other metrics). FEAT (Features) is the fraction of notable features supported. GFX (Graphics) scores 100% for modern protocols (iTerm2, Kitty), 50% for legacy only (Sixel, ReGIS), 0% for none.
Final Scaled Score: 70.8% (normalized across all terminals tested). Final Scaled scores are normalized (0-100%) relative to all terminals tested

DEC Private Modes Support

This Terminal does not appear capable of reporting about any DEC Private modes.

Kitty Keyboard Protocol

Konsole does not support the Kitty keyboard protocol.

XTGETTCAP (Terminfo Capabilities)

Konsole does not support the XTGETTCAP sequence.

Text Sizing Protocol (OSC 66)

Konsole does not support the Text Sizing protocol.

Truecolor Support

Konsole supports 24-bit truecolor, detectable via:

XTGETTCAP (RGB capability): no
DECRQSS (truecolor probe): no
COLORTERM: yes (truecolor)

Warning

COLORTERM is an environment variable, not a terminal query. It is not forwarded over SSH without SendEnv / AcceptEnv configuration, so detection via COLORTERM alone may be unreliable on remote hosts.

XTVERSION (raw): Konsole 23.08.5
XTVERSION: yes
XTGETTCAP TN: no
ENQ: no
TERM_PROGRAM: no
TERM: no (xterm-256color)
