Added by Fux77 Example lcd4linux configuration for a l4m132c (132x65) usb display with shown covers 
Edit
Driver serdisplib has to be installed for l4m132c [1] Installation guide in german
For showing covers i use the cover database from gmpc. I convert all the covers to a size of 45x45 by a script (see attached perl script below).
Please fit "/home/user/.covers/" to your gmpc cover directory:
# /etc/lcd4linux.conf file '/home/user/.covers/'.mpd::artist().'/'.mpd::album().'_45x45.png'
Please fit "HID:/dev/usb/hiddev0" to your l4m132c device (normally: /dev/usb/hiddev0 or /dev/hiddev0).
# /etc/lcd4linux.conf Port 'HID:/dev/usb/hiddev0'
If you have a problem with changing device names (caused by another usb devices) you may add a line to the udev config:
# /etc/udev/rules.d/10-own.rules
BUS=="usb", KERNEL=="hiddev?", SYSFS{idVendor}=="4243", SYSFS{idProduct}=="ee08", SYMLINK+="usb/usblcd"
Use in this case the symlink "/dev/usb/usblcd" instead of "/usb/dev/hiddev1".Known problems:
- Covers with albumartist="various" currently aren't shown. The lcd4linux code don't compiles with the actual mpdlib.
- German "Umlaute" aren't showed. The reason is unknown.
