Bug#401919: X11 bug: Keyboard event does not correspond modifiers map
Package: xfree86-common
version: 4.3.0.dfsg.1-14sarge1
Hello!
There is a such a bug in X: Alt_R acts as Alt modifier, though
it does not exist in modifiers map.
Here I started xev, pressed right alt, then pressed "l",
then released it, and after all, released right alt:
--------- start xev output --------
KeyPress event, serial 18, synthetic NO, window 0xa00001,
root 0x38, subw 0x0, time 35520663, (113,98), root:(626,116),
state 0x0, keycode 113 (keysym 0xffea, Alt_R), same_screen YES,
XLookupString gives 0 bytes: ""
KeyPress event, serial 23, synthetic NO, window 0xa00001,
root 0x38, subw 0x0, time 35520956, (113,98), root:(626,116),
state 0x8, keycode 46 (keysym 0x6c, l), same_screen YES,
XLookupString gives 1 bytes: "l"
KeyRelease event, serial 23, synthetic NO, window 0xa00001,
root 0x38, subw 0x0, time 35521058, (113,98), root:(626,116),
state 0x8, keycode 46 (keysym 0x6c, l), same_screen YES,
XLookupString gives 1 bytes: "l"
KeyRelease event, serial 23, synthetic NO, window 0xa00001,
root 0x38, subw 0x0, time 35521205, (113,98), root:(626,116),
state 0x8, keycode 113 (keysym 0xffea, Alt_R), same_screen YES,
XLookupString gives 0 bytes: ""
------- end xev output -------
you see, state is 0x8, it is 1<<3, it means than Mod1, the 3th modifier
is active
But when I launch xmodmap I receive such a message
--------- start xmodmap output --------
xmodmap: up to 3 keys per modifier, (keycodes in parentheses):
shift Shift_L (0x32), Shift_R (0x3e)
lock Caps_Lock (0x42)
control Control_L (0x25), Control_R (0x6d)
mod1 Alt_L (0x40), Alt_L (0x7d), Meta_L (0x9c)
mod2 Num_Lock (0x4d)
mod3
mod4 Super_L (0x7f), Hyper_L (0x80)
mod5 Mode_switch (0x5d), ISO_Level3_Shift (0x7c)
--------- end xmodmap output --------
as xmodmap describes only Alt_L, Alt_L and Meta_L act as Mod1,
not Alt_R (who's code is 0x71 btw)
why?
when using XNextEvent I receive the same effect as in xev output:
right alt is treated as an Mod1 key
XGetModifierMapping says the same as xmodmap
Here's my XF86Config-4 file:
