I suspect that the interface that SDL2 uses to determine power status under Linux has been deprecated and removed. I'm running Debian GNU/Linux 7.4 (wheezy) on a ThinkPad T410. SDL_GetPowerInfo returns SDL_POWERSTATE_UNKNOWN and the secs and pct parameters both come back as -1. It looks like the file paths specified in power/linux/SDL_syspower.c are no longer used. I spent a little time trying to redirect things but didn't have any luck.

By default Wheezy uses 3.2, there are backports of newer Kernels though. See also https://packages.debian.org/wheezy/linux-image-amd64 Cheers, Daniel

Ah, okay, apparently /proc/acpi is deprecated (too!), and now they want us to use D-Bus or something. I'll put it on the TODO list. --ryan. _______________________________________________ SDL mailing list http://lists.libsdl.org/listinfo.cgi/sdl-libsdl.org |
