Hello Tan,
I may be getting a bit out of my element here so I welcome any input from
other lurkers.
Regarding the xconfigure utility, sorry for the confusion, I didn't
realize it was something that came with Nano-X.
The error that you are encountering appears to be generated by Nano-X's
frame buffer driver code (that talks to the Linux frame buffer????). I'm
running 0.91, and I recommend that you do the same, and in my setup, the
file .../src/drivers/scr_fb.c, line 233 is where the error is occurring.
Here's the code snippet:
#if HAVETEXTMODE
/* open tty, enter graphics mode*/
tty = open ("/dev/tty0", O_RDWR);
if(tty < 0) {
EPRINTF("Error can't open /dev/tty0: %m\n");
goto fail;
}
if(ioctl (tty, KDSETMODE, KD_GRAPHICS) == -1) {
EPRINTF("Error setting graphics mode: %m\n");
close(tty);
goto fail;
}
close(tty);
#endif
This is why I asked you about text mode. It looks like the system is
successfully opening the TTY device but the ioctl for switching to
graphics mode is failing. I'm going to go out on a limb and suggest that
you try setting HAVETEXTMODE to N. I'm not promising that it will work,
but it might tell you something.
