Can't run games

[camjrp]

I just compilled EmulationStation from source to run it with retroarch, no retropie, in my linux laptop machine (xubuntu)
Whenever i try to run a game i'm getting this error in the terminal
"camilo@camilo-S400CA:~$ emulationstation
lvl0: CECInput::mAdapter->DetectAdapters failed"

¿What can i do?

Here is a copy/paste of my ES config fyle

<!-- This is the EmulationStation Systems configuration file.
All systems must be contained within the <systemList> tag.-->

<systemList>
<!-- Here's an example system to get you started. -->
<system>

	<!-- A short name, used internally. Traditionally lower-case. -->
	<name>nes</name>

	<!-- A "pretty" name, displayed in menus and such. -->
	<fullname>Nintendo Entertainment System</fullname>

	<!-- The path to start searching for ROMs in. '~' will be expanded to $HOME on Linux or %HOMEPATH% on Windows. -->
	<path>/home/camilo/Emulation/Roms/Nes/</path>

	<!-- A list of extensions to search for, delimited by any of the whitespace characters (", \r\n\t").
	You MUST include the period at the start of the extension! It's also case sensitive. -->
	<extension>.nes .NES</extension>

	<!-- The shell command executed when a game is selected. A few special tags are replaced if found in a command:
	%ROM% is replaced by a bash-special-character-escaped absolute path to the ROM.
	%BASENAME% is replaced by the "base" name of the ROM.  For example, "/foo/bar.rom" would have a basename of "bar". Useful for MAME.
	%ROM_RAW% is the raw, unescaped path to the ROM. -->
	<command>retroarch -f -L /home/camilo/.config/retroarch/cores/nestopia.libretro.so %ROM%</command>

	<!-- The platform to use when scraping. You can see the full list of accepted platforms in src/PlatformIds.cpp.
	It's case sensitive, but everything is lowercase. This tag is optional.
	You can use multiple platforms too, delimited with any of the whitespace characters (", \r\n\t"), eg: "genesis, megadrive" -->
	<platform>nes</platform>

	<!-- The theme to load from the current theme set.  See THEMES.md for more information.
	This tag is optional. If not set, it will default to the value of <name>. -->
	<theme>nes</theme>
</system>

</systemList>

@camjrp Are you sure you're core name is nestopia.libretro.so and not nestopia_libtretro.so ? Try running the emulator start-up command from the command line and see if you get any errors, then adjust it in the .cfg file.

Thanks, i was incorrectly naming the core, now the game runs
However i kept getting this error message in the terminal
camilo@camilo-S400CA:~$ emulationstation
lvl0: CECInput::mAdapter->DetectAdapters failed
Protocol error: bad 3 (Window); Sequence Number 11
Opcode (20, 0) = GetProperty
Bad resource 0 (0x0)
at -e line 16.
lvl0: CECInput::mAdapter->DetectAdapters failed

Don't know what it means

@camjrp Those errors seem related to your Xorg installation or desktop environment.
