Workaround for WM Focus Issues
|
|
/me punts
What follows is an ugly hack. Continue reading at your own risk. ;)
I'm using Fluxbox 0.9.x as a WM and have tried RatPoison and TWM. With
all three, I have been having a problem that after running xine,
mythfrontend receives focus, but on certain screens (such as the "Do you
really want to exit" screen and the Program Guide, among others), there
are "focus issues." For example, the exit screen displays with neither
the Yes nor the No button highlighted and I have to move the mouse to
"reset" focus so I could select one or the other. On the Program Guide,
I am able to move one space in any direction and after doing so the
arrow keys stop working (but the escape key works fine????) until i
"reset" focus with the mouse.
I tried all day to figure out what setting I needed to change--testing
various configurations of Fluxbox (focus policies, new window focusing,
autoraise, etc.) and xine (gui.always_layer_above and gui.always_layer,
etc.)--and after several hours without any luck, I took the easy way out.
Since it's possible to regain focus by moving the mouse to the edge of
the screen and then back into the mythfrontend window, I wrote a script
to do that for me. Yes, I know this is treatin the symptom and not the
problem. No, I don't live in Redmond, WA. ;)
The movemouse script uses the X Windows XTrap extension to perform a
simple movement of the mouse cursor (moves the mouse to 0,0, then in a
small box around the screen (screen size >= 640x480), and leaves it well
within the mythfrontend window (at 320, 240)). To use the script, you
must load the xtrap module: verify you have xtrap by running "man
xtrap" or "which xtrapin" and, if available and if you haven't done so
before, add the "Load" line below to the modules section of your
XF86Config or xorg.conf as shown (do not remove any other "Load" lines
you may have).
Section "Module"
Load "xtrap"
EndSection
Make sure your WM is set to use sloppy or semi-sloppy focus (as
appropriate for your WM), and ensure that the movemouse script is run
after using any program that causes focus problems. I did so by
creating a script ~mythtv/bin/xine that calls /usr/bin/xine with the
supplied arguments and then runs the movemouse script (see the three
line script below). Appending a "; movemouse" to the end of your player
command should also work. The script completes in 60ms, so you
shouldn't even notice it (but if you do, feel free to change the value
of TS from 10 to some smaller number of ms :).
If anyone knows of a solution to the problem or a less ugly workaround,
please let me know.
