K3 digging around in startx

[hawhill]

I vaguely remember specifying "novt" as TTY on the command line, or things like "-novtswitch", "-keeptty" and similar stuff. But that's certainly dependent on the variant of X server in use. I also remember lots of patches floating around in various message boards that deal with patching out the TTY handling. After all, it's usually just a few lines within the sources that are easy to find (openvt, deallocvt, chvt are the tokens to search for).

[knc1]

On searching for patches . . . .
You might find one that grabs two /dev/event/?? thingies and turns them into a "current terminal" (a.k.a: /dev/tty0)

Hmm...
Which is what the kernel would do internally IF Amazon had optioned in vt handling.
I don't think virtual terminals can be added with a loadable module, so that route is out.

[qlob]

vt support can be compiled into a new kernel, though, right?

[twobob]

well then. new kernel it is, but I dont think that's a very portable solution.

I'll make one later then

And I think it might really be overkill. I'm quite interested in a working X server, so maybe I'll find time to dig into this. But I bet if Lab123 ever got one working, it would have been a patched one. Maybe the file is just a left over from earlier stages when they were still experimenting. I would not pay overly much attention to "startx"... I'll have some spare time for my Kindle (and experiments with X servers on it) this weekend...

Yeah I really wasn't giving it too much attention. I've read it beginning to end a few times and removed some of the sillier bits.

Way I see it that is a nice way to get into a graceful state ready for X launching.

anyway there is a mount rw half way through it that is never closed off. so that's probably not the best ever complete solution

I would be extra happy if you did. many thanks.

Have a whole pile of supporting libs and applications built should you want them. nothing you couldn't build yourself though probably.

Would be great to have a native X as an option.

I also note

[root@kindle bin]# ls /dev/pts/*

/dev/pts/0 /dev/pts/1

which are the psuedo-ttys. I shall read up what they actually are.

I don't think those will help you any.

Are you looking at this via the graphic's display of Linux Mint (or almost any X11 display)?
Good, I thought you might be.

Now to get a key sequence past X11 in this case, you need to prefix the virtual terminal key sequence with 'ctrl', otherwise, don't use control (you might want to remember these before pressing the first:
ctrl-alt-f1 : VT1
alt-f2 : VT2
alt-f3 : VT3
alt-f4 : VT4
alt-f5 : VT5
alt-f6 : VT6
alt-f7 : VT7 - on which Linux Mint runs X11 display 0:0
Under a 'stock' Linux Mint, you only have one graphic display and 6 character based terminals

If you want to, you could log in on any of those others (just remember were you put things if using more than one and who you are, if logging in under a different user name).
They each have a 'getty' running on them. (see: /etc/inittab)

If you want to, you could also run 'getty' on f8, f9, f10, f11, f12

Whichever one you are looking at, at the moment, that is /dev/tt0
(Linux Mint is nice to the lost person - it tells you which one you just selected above the new login prompt).

Fun? Right!

And yes, you don't have to run 'getty' on the VTs, you could run something else (like a dedicated game program, or even another X11 session - that is under the control of your X11 config stuff).

If you want to play 1970's fun*, run a serial cable from your box's serial port into another room with a 'dumb' terminal attached, then read notes in inittab about how to assign one of the VTs to that serial cable.

If you can remember the '70s, you weren't where the action was.

I also remember lots of patches floating around in various message boards that deal with patching out the TTY handling. After all, it's usually just a few lines within the sources that are easy to find (openvt, deallocvt, chvt are the tokens to search for).

nothing like that in tiny X switches. will have a source dive but I need greater knowledge of the end goal.

I'll have a look at modular X next then. see what that holds. Thanks : )

Ironically I am using a vista latop for the 1st time in forever.

As a guywho struggles to remember yesterday I can safely class me as "having been there" : )

will have a play when I jump on the main box mate, much appreciate the insights!

[twobob]

Okay so I got a swanky new Toolchain to throw at this.

Modular X is also an option.

Will wait to see what Hawhill comes up with though : )

Well, I got Xfbdev running. I had to patch it, however. Patch is attached, buildroot will apply it automatically when you put it (gunzipped) in the package/x11r7/xserver_xorg-server directory.

I also needed to patch the resulting binaries since I did not want to create a chroot or mess with my root partition. Thus I patched (in Xfbdev and xkbcomp) as follows:

sed -i 's/\/usr\/share/\/mnt\/us\/sh/'
sed -i 's/\/usr\/bin/\/mnt\/us\//'

(with GNU sed on the host machine)

That said - it works resonably well with a big glitch. I didn't test input on the K3, however - I used x2x for a quick drive.

The big glitch is that it gets the ordering within framebuffer bytes wrong. So it will display odd/even horizontal position exactly the wrong way - stuff ends up garbled. Found traces of others having the same problem on the Web, but did not dig further.

Well, and then of course it's not updating the eink screen either. For testing, I just used a quick and dirty loop like this:

while sleep 5; do echo 1 > /proc/eink_fb/update_display ; done

Excellent. going to give this a run through the new toolchain right now then.

Appreciate the patch being the perfect format. nice touch.

Well bugs are my headache. BIG THANKS!!!

here I go


EDIT: Oops.. It built perfectly. patch, new toolchain everything great! Went to put it on the 3 and DOH!!! I have let it run flat. HEH...

Tomorrow then.

[twobob]

quick update. got it running. thanks
