thank you, robert. [video] I installed fbset. "apt-get install fbset". on a 1920x1080 monitor, it selects 1280x800. 1280x1024 is a limit of the 125MHZ clock the AM3359 . this is why xres 1920 yres 1080 is a no go. as robert has pointed out (repeatedly), this can be changed by hand at boot time in uEnv.txt . (on my monitor, one video problem is that it cuts off a little at the bottom.) https://groups.google.com/forum/#!searchin/beagleboard/Robert%7Csort:date/beagleboard/Nb5TQxykUo4/9MIJYFQB43YJ
Q: can the arm kernels use VESA text modes, such as 60x132 ? I don't need to display graphics in a frame buffer. I would be perfectly happy with a text mode. (my guess is no.) [usb client] apt-get install udhcpc yields busybox and udhcpc . I also installed usbutils . but there must be some other package to get usb to work. it's not just that the networking over usb does not work, it is also that usb doesn't present anything on its usb client port to the usb host (i.e., my notebook computer). what package am I missing? (would it make sense to include this by default in 7.8? it's probably widely needed.) regards, /iaw ---- Ivo Welch ([email protected]) http://www.ivo-welch.info/ J.
