Description jbibollet 2007-11-20 00:11:39 UTC

In the /usr/include/X11/XF86keysym.h file there are definitions for keys to 'handle' monitor backlight:
/* Backlight controls. */
#define XF86XK_MonBrightnessUp   0x1008FF02
#define XF86XK_MonBrightnessDown 0x1008FF03
#define XF86XK_KbdLightOnOff     0x1008FF04
#define XF86XK_KbdBrightnessUp   0x1008FF05
#define XF86XK_KbdBrightnessDown 0x1008FF06

But xmodmap doesn't seem to be able to use them:
xmodmap -e "keycode 169=XF86MonBrightnessUp"
xmodmap:  commandline:1:  bad keysym name 'XF86MonBrightnessUp' in keysym list
xmodmap:  1 error encountered, aborting.

Every other keys definition in this file are recognized by xmodmap, except those  ones.

Some information about my system:
gentoo, amd64, libX11-1.1.3, xorg-server-1.4-r2, xmodmap-1.0.3

Works for me.
These definitions should come from the entries in <prefix>/share/X11/XKeysymDB -
is that file correctly installed on your system and contain those entries?

According to equery, the XKeysymDB file is correctly installed (from the libX11 package):
equery belongs /usr/share/X11/XKeysymDBKeysy
[ Searching for file(s) /usr/share/X11/XKeysymDB in *... ]
x11-libs/libX11-1.1.3 (/usr/share/X11/XKeysymDB)

However, it doesn't contain any of the symbols I mentioned in my first post:

cat /usr/share/X11/XKeysymDB | grep -i bri
SunVideoLowerBrightness :1005FF7B
SunVideoRaiseBrightness :1005FF7C
XF86BrightnessAdjust    :1008FF3B

Ah, that's what I get for testing on a system running builds from the git
sources - these were added to XKeysymDB in git since the last libX11 release:

commit 7c996f78914c77fe17e9f4feede980d895d9df51

    Add XF86 keyboard/monitor brightness keysyms to the keysymbdb.

Marking as FIXED since it's fixed in the git master repository.
