TI-Nspire / Re: Calling all Linux Kernel developers!
« on: September 06, 2015, 10:52:54 pm »
Hello, another noob here. I read about linux on the nspire a while ago, and seeing as I now use CAS more often (and can't put a CAS os on my rev. J CX) I figured that I'd give it a try. I followed codinghobbit's tutorial and installed Debian on my calculator. Then I compiled the (device tree) kernel using vogtinator's config with a couple kernel options added to get my usb ethernet adapter working. That worked too. Now I'm trying to get x working.
Installing xorg on debian failed. "Hmm, maybe it's something to do with debian packages."
Fine, instead of debian, put the latest xconfig rootfs from tiplanet on my flash drive, since I've seen videos of xconfig working.
It boots, but gives a similar error when I try to do startx [attached]. "Ok, maybe it's a problem with my kernel."
Replaced the kernel I built with the latest from tiplanet (also device tree).
The same error occurs.
Both my kernel and the tiplanet one were kernel version 4.2 "Ok, maybe newer kernels don't work."
Fine, install the latest old kernel (non device tree) from tiplanet.
It boots, and startx does start x, but none of the inputs work; the cx keyboard and touchpad don't do anything, so I can't type anything. I don't have a usb keyboard, but I do have a mouse. It doesn't move the mouse cursor. I can tell that it isn't frozen because the clock still works. Then after a couple minutes, the screensaver kicks in and the screen turns off. I can't get out of it, and have to use the reset button.
Therefore, a couple questions:
First, is x possible with the newer kernels? How do I get it working? More kernel options?
Second, how do I get the inputs to work in X? I don't know if the touchpad can work as a mouse, but the keyboard should work. I have looked around and found the "evdev" driver Could this be it? How do I enable it?
At this point I should say that I don't really know what I'm doing. I know some Linux stuff from playing with Raspberry pi, but I've never really done anything at this lower level. I'm just good at googling and poking around.
