After installing lcdproc on my pi i am getting this error.
glcd/glcd2usb: could not set configuration: could not set config 1: Device or re source busy
glcd: normal_font missing in configuration
Driver [glcd] init failed, return code -1
Could not load driver glcd
There is no output driver
Critical error while initializing, abort.
There may be two errors here.
First, it looks like LCDproc has been compiled with FreeType support (which may be default if FreeType is installed).
Unfortunately FreeType is also enabled by default, but the required font has no default setting. Look for normal_font in LCDd.d conf and set it a some useful font. Or disable the use of FreeType ('useFT2=no').
Scond, 'could not set configuration' is just a warning. I have never seen it with my devices and it may work anyway.
