Package: vnc-java
Version: 3.3.3r2-7
Severity: minor
Steps to reproduce:
1) start VNC, connect to it using vnc-java and start xev inside it
2) hit altgr
Expected results:
2) xev prints something along the lines of
KeyPress event, serial 25, synthetic NO, window 0x1800001,
root 0x2e, subw 0x0, time 1497292417, (102,122), root:(167,711),
state 0x0, keycode 255 (keysym 0xfe03, ISO_Level3_Shift), same_screen YES,
XLookupString gives 0 bytes:
XmbLookupString gives 0 bytes:
XFilterEvent returns: False
KeyRelease event, serial 25, synthetic NO, window 0x1800001,
root 0x2e, subw 0x0, time 1497292522, (102,122), root:(167,711),
state 0x0, keycode 255 (keysym 0xfe03, ISO_Level3_Shift), same_screen YES,
XLookupString gives 0 bytes:
Actual results:
2) xev prints
KeyPress event, serial 28, synthetic NO, window 0xa00001,
root 0x2e, subw 0x0, time 1497366784, (112,20), root:(177,365),
state 0x0, keycode 107 (keysym 0xffff, Delete), same_screen YES,
XLookupString gives 1 bytes: (7f) "^?"
XmbLookupString gives 1 bytes: (7f) "^?"
XFilterEvent returns: False
KeyRelease event, serial 28, synthetic NO, window 0xa00001,
root 0x2e, subw 0x0, time 1497367069, (112,20), root:(177,365),
state 0x0, keycode 107 (keysym 0xffff, Delete), same_screen YES,
XLookupString gives 1 bytes: (7f) "^?"
XFilterEvent returns: False
so that altgr is interpreted as DEL which is clearly an error.
More info:
1) Since icedtea-gcjwebplugin seems to send 0xffff as keyid it seems
the issue can be fixed by extensing the already-in-place workaround by
one:
