Bug 4814

Summary: Missing scancodes on Linux
Product: SDL Reporter: Michael Roe <mroe1492>
Component: eventsAssignee: Sam Lantinga <slouken>
Status: RESOLVED FIXED QA Contact: Sam Lantinga <slouken>
Severity: normal    
Priority: P2    
Version: HG 2.0   
Hardware: x86_64   
OS: Linux   

Description Michael Roe 2019-10-04 21:13:15 UTC 
The mappings for keyboard scancodes on Linux do not include keypad left and right parentheses (used on some Microsoft keyboard), keypad plus/minus, LANG1 and LANG2 (used on Korean keyboards), XK86MenuKB, and F20 (remapped to Audio Mic Mute in the usual X11 config).

Here's a patch to fix it.
