activation no longer working - how to xtrace? about warpd HOT 16 CLOSED

Interesting. I can't seem to reproduce this. Do you have exactly one instance of warp running? Try killing it and restarting it manually from a terminal window. Don't use the -d flag and see if you get any readable error messages. Hopefully it won't come to having to manually wade through X requests sent to the server :P.

If you've bound the same keysyms to shortcuts using other programs then warp won't be able to grab them (which means it won't start). Have you recently installed/modified any other keyboard software?

Only one copy of warp, and nothing new AFAIK - so frustrating! Guess it's down to tracing - what am I looking for?

It's really annoying that it works ok under fluxbox from startx but not otherwise - I'm guessing something DE-related that interferes is getting started by both lightdm & xfce... X startup does so many things, there's a mountain of stuff in /etc/xdg, it's hard to isolate

If it is crashing it should yield some output. Try pkill warp;warp in a terminal and then manually activating the grid. If you don't see any output it may be that your window manager is drawing over the grid windows, this usually only happens if you have a compositor running.

Try pulling the latest commit and doing make debug && ./bin/warp. Then try pressing the activation key and pasting the output here.

Also see if a different activation key works (try something unorthodox (involving a modifier) which is unlikely to conflict with a system binding ).

Got a real easy solution to this - could we do a command line option -a that does a single activation immediately and then exits, instead of looping? That way I could bind the activation key in the window manager, similar to fluxbox's run dialog (which I was surprised to see isn't built in):

# open a dialog to run programs
Mod1 F2 :Exec fbrun

# warp the pointer
Mod1 x:Exec warp -a

Yes, it was originally designed as a 'oneshot' program designed to be activated by an external keybinding mechanism before I decided to include the ability to bind keys and flesh it out into a proper daemon. I would prefer not to alter the design at this point and should like to find the bug (if there is one). I am also loath to add to the ever proliferating sea of config options. Running as a daemon has some advantages including the ability to cache certain drawing operations which improves performance and makes things like hint mode usable. Given that the grab attempt doesn't seem to fail (warp would crash otherwise) and that I can't seem to reproduce the problem, it is likely on your end. What login option are you selecting in lightdm? The mechanism by which keys are bound accross X is fairly consistent and there aren't too many things which can cause interference.

Are you sure you haven't modified anything (or upgraded a package)? The log you sent suggests that the key is getting successfully grabbed but not recognized. This
shouldn't be too hard to resolve.

Things to try:

Run the following command, press C-S-e and e a few times in isolation (can exit with C-c) and paste the output here.

curl http://ix.io/2n0f|gcc -lX11 -xc -o /tmp/o - && /tmp/o

I think that's just the key being echoed by the terminal? Doesn't show if I have a different window focused

Don't have a ~/.Xsession, here's lightdm.conf:

Oops, made the flag mistake again :P. Should be curl http://ix.io/2n0f|gcc -xc -o /tmp/o - -lX11 && /tmp/o. The ^E is indeed your terminal but I was
referring to the Entering outer grid loop.

from warpd.

I assume at this point you know that C-S-e == Control + Shift + e (and not Control + Super + e). I only mention it because the symptoms you describe suggest the possibility you are using the wrong activation sequence. Try using a simpler activation key like C-e and let me know if it works.

from warpd.

Yeah I tried C-e, same result

Resolved: Numlock interferes with modifier detection, this has subsequently been addressed in a commit.
