Guillaume:

Please check my last post before releasing 0.4.4
There seems to be some driver error with HD44780. I checked it last=20
night. (It's possible that i'm a total idiot ;-) but i got the curses=20
and mtxorb drivers to work.)

"Ok. now i've tried the curors driver and it vorks just fine in both=20
0.4.3
and 0.4.4, exept the [M]memory,proc_[S]izes using /proc/meminfo and
CPU-SM[P] that give me error "%get_load: Bad file descriptor".
But with 0.4.4 i get:
"invalid driver: HD44780
Could not load driver HD44780
There is no output driver
Critical error: main.c:238, abort"
Any ideas ??
