Description of problem:
TigerVNC does not support a typical 9 button mouse.
Version-Release number of selected component (if applicable):
all including upstream source
Steps to Reproduce:
1. Own 9-button mouse (L/R/middle, wheel up/down, wheel L/R, back, forward)
2. view xinput/xev information via vnc and use mouse
first 7 events (through wheel L/R) are sent). Back/Forward (side buttons) are not sent.
back/Forward buttons work.
#define BUTTONS 7
This limit requires non-free software for VDI applications.
Also tested with spice and didn't have the capability of all 7 buttons.
Hmm, it seems that in the end we cannot fix it this way and actually we cannot fix ithis at all. According to specification the RFB protocol can support only up to 7 mouse buttons. I should have read the specs first.
