Re: [hackers][slock] making slock set the keyboard layout to English before locking the screen

[Lancia Greggori]

Hi, yes, thank you very much, I apologize for such a seemingly simple
solution flying over my head.

Also thanks to Augusto Castelo for responding and giving me insight about
how slock works.

Hi Lancia. Does "setxkbmap us && slock" do what you want?

Re: [hackers][slock] making slock set the keyboard layout to English before locking the screen

Hi,

I think the problem is that the post-lock command runs as nobody​, when 
modifying slock you should run setxkbmap us​ before dropping privileges (before 
line 349 on an unpatched version).

Cheers!

[hackers][slock] making slock set the keyboard layout to English before locking the screen

[Lancia Greggori]

Hi gentleman, as the title suggests, I need slock to automatically set the
keyboard layout to English because sometimes my keyboard layout is in
another language when slock locks the screen and this causes my typed
password to be rejected by slock as incorrect because it has been entered
in foreign characters.

What I have tried so far:

1- using setxkbmap(1) with slock(1):

   $ slock setxkbmap us
  Authorization required, but no authorization protocol specified
  Cannot open display ":0"

  $ slock env setxkbmap us
  Authorization required, but no authorization protocol specified
  Cannot open display ":0"

2- editing slock.c and using system(3) to execute setxkbmap(1):

system("setxkbmap us");

/* everything is now blank. Wait for the correct password */
readpw(dpy, &rr, locks, nscreens, hash);

output of slock(1):

   Authorization required, but no authorization protocol specified
   Cannot open display ":0"
   Terminated ---> guess: caused by root using killall(1)


I am not familiar with Xorg programming, but I am guessing there might be a
function or something that will set the keyboard layout to English.

Can anyone kindly give me pointers or hints?
