Add four new private XKB actions for debugging:
* PrGrbs: print active grabs to the log file
* Ungrab: ungrab all currently active grabs
* ClsGrb: kill clients with active grabs
* PrWins: dump the current window tree to the log file
To use these, you need to modify your XKB maps, e.g. the following to
have Ctrl+Alt+(F9-F12) mapped to the above:
- compat/xfree86:
interpret XF86LogGrabInfo {
action = Private(type=0x86, data="PrGrbs");
};
interpret XF86Ungrab {
action = Private(type=0x86, data="Ungrab");
}
interpret XF86ClearGrab {
action = Private(type=0x86, data="ClsGrb");
}
interpret XF86LogWindowTree {
action = Private(type=0x86, data="PrWins");
}
- symbols/pc:
key <FK09> { type="CTRL+ALT", [ Return, XF86LogGrabInfo ] };
key <FK10> { type="CTRL+ALT", [ Return, XF86Ungrab ] };
key <FK11> { type="CTRL+ALT", [ Return, XF86ClearGrab ] };
key <FK12> { type="CTRL+ALT", [ Return, XF86LogWindowTree ] };
At the moment, this only works if the grabbing client continues to call
AllowEvents, as the server does no event processing at all when a device
is frozen.
