Starting an application under X

[lbalan79]

Ok. Because it looks that fas part of this pdf a new version of X / gnome is installed. With my limited understanding this chroots into the new ubuntu installation where a new version of X would be present. As a result it is obvious that the drivers would not work.

Finally, it?s time to install our desktop environment, here you can choose between a large variety and flavors, I?ve tested both the original Gnome (now Unity), and the Lightweight X11 Desktop Environment. I can tell Unity works better in my case so let?s go for it: o root@(none):/# apt-get install ubuntu-desktop 2> /error.log The installation of the desktop may take more than an hour, it will install all gnome tools (text editor, graphic terminal, calculators, some game?), drivers, make some configurations, etc? This is why I redirect the error stream to a file, so I can check is something went wrong more easily.

NOPE. It uses EXISTING X but new gnome. The drivers don't work because we use EXISTING X Existing X has no driver support

If existing X has no driver support how does the sound and remote works in HUB (exeAPP)? Also I have Need for Speed running so that must have some kind of audio support.

Thank you

"Drivers" are IN exeAPP/exeTV NO STANDARD X app can access them !!! Besides start reading more:P X NEVER had ANY sound drivers They are either in kernel (NOT ON TV) or handled by each app separately (line on TV). So if you write your own app you have to write your own sound handling

[lbalan79]

You are right. They seem to use SDL for the basic applications. The kernel drivers should work work fine under X as well. Well... I am too much of a noob in this area.
GAME_LIB/libSDL.so
https://www.libsdl.org/ .

But getting back to the main topic is there anyway to open for example a shell under X directly from command line without chroot into ubuntu and installing gnome?

Thank you

Yes but there are NO sound kernel drivers Samsung is talking directly to hardware using their proprietary API

I don't understand a question and I don't understand where do you want to get with this discussion

You probably are right for exeAPP I find imports for the Audio methods. SDL however uses the kernel drivers:

I don't understand a question and I don't understand where do you want to get with this discussion

I just want to start an X application using the same xorg.conf and settings as on the screen. I don' tneed window decorations or anything fancy as gnome or kde have. The final goal is to put a mame emulator on the tv but that is a far fetched goal so I am taking it baby steps and hopefully learn a thing or two in the process.

Well it doesn't matter since you have two main obstacles:
1) How to get to sound
2) How to get any input .
By default X applications DO NOT receive ANY input exe* have compiled in custom "drivers" NOT usable by any other X app

Right. But I am not even getting a normal terminal to start up under the current screen. So trying to get that going first. Sound and controls is second priority now. So my issue now is how to get a simple xterm application to display without chrooting.

Thank you,

Ahh so for you "normal terminal to start up under the current screen" is xterm Did you compile xterm yourself using TVs toolchain and libs ?
