I've been searching for solutions to this problem on-and-off for about four months now, with no success. I think it's time I turn to StackExchange for input.
I run a dualboot with Windows 8.1 and Ubuntu 14.10 (x86_64) with the i3 window manager, and, seemingly at random,
feh will either work, or not work, with fullscreen mode (hitting v triggers fullscreen). By "not work", I mean it will not react to any keystrokes, until I kill it with
^C, and am met with the following error message:
braden@braden-Aspire-XC-603G:~$ feh Pictures/img.png feh WARNING: Window Manager does not support MWM hints. To get a borderless window I have to bypass your wm. vq^Cbraden@braden-Aspire-XC-603G:~$
Yet on other startups, it sometimes works. Sometimes it works, sometimes it doesn't. It seems to work consistently if I boot with an alternate kernel, but I don't think booting with an older kernel is an optimal choice here.
Clearly, i3 supports mwm hints, otherwise feh's fullscreen mode would work 0% of the time, so how can I go about forcing feh to work in fullscreen?
If I can't get it to consistently work with mwm hints, can I force feh to at least accept keystrokes in fullscreen mode?
