Xorg: What is it, and what does it mean?
 

Just a thought is this something that should be deleted? This seems to be using about 7% of my RAM

Re: Xorg What is it and What does it Mean
 

No no no no no. You still want a GUI, right?

Re: Xorg What is it and What does it Mean
 

I dont know what a GUI is but sounds like I should leave this alone and maybe it should be there. Thanks

Re: Xorg What is it and What does it Mean
 

No, it is an important part of Maemo. The X.Org Server is the bit that lets things appear on the screen.

Yes, it is rather large as it provides many important underlying technologies to Maemo.

I have a lot of learning to go and just think I have root access now gulp...

Will not touch thank you! :)

It is your graphical interface. If you delete it, you're hosed. Wikipedia knows:

Its sad, but reading this brought a smile to my face. :D

The idea of the horror on the faces of everyone who read this post.

Its kinda like going to a Windows forum and saying "you know explorer.exe is eating a lot of RAM, can I just delete it?". Not exactly the same thing (Windows would be much more easily recoverable than the N900) but still, its the kind of thing where everyone in the room in tandem goes "NOOOOOOOOOOOOOOOO!" at the same time.

I did check though out of curiosity, if you had killed xorg it simply triggered a shutdown and safe reboot. Probably the safest course of action if it crashed for some reason. Now deleting it on the other hand, well I guess it would trigger the same but it would be an infinite reboot cycle.

Xorg/x11 is a set of libraries/protocols that allow drawing to the screen. (x11 is the name of the protocol, just like http is the name of the protocol used for www)

GTK, QT, OpenGL, Window Managers (matchbox2) and all the other UI stuff you hear about here all go on top of/through X11.

Without X11 on linux, your only other options are direct framebuffer access (the older Qtopia platform was also linux based and eschewed X11 for direct framebuffer access to reduce overhead) or just a console (text command line).

X11 also provides network transparency, making it possible to run apps on one machine, and have them display on another (like running openoffice on my desktop, but having the UI display on my n900)

As a fun sidenote, you can try using the framebuffer out option in mplayer on the n900 and watch x11 and mplayer compete for drawing the screen :)

Re: Xorg: What is it, and what does it mean?
 

Speaking of, have you gotten applications run over SSH to display on the N900?

I know its doable and desktop Linux does it by default. However on the N900 it seems it may be disabled by default as it doesn't work and its hard finding information about how to get it working as hardly anyone seems to use that functionality any more.

Re: Xorg: What is it, and what does it mean?
 

When you run ssh, run it like "ssh -XY". You may want to throw in a "-C" for compression as well.

You may need to configure something on your server end too, but usually that does the trick (e.g. it works with default Debian lenny).

If it's not on a LAN, it's pretty slow though and VNC would be faster. I have some info about VNC here:
http://wiki.maemo.org/User:Jebba#VNC

The *best* solution would be to use NX as it is much faster (less data transfer). There are some NX packages in extras-devel right now too (see qtnx).

iirc, there are two reasons why xorg shows a lot of ram used.

1. its reported ram includes any ram related to the graphics hardware.

2. xorg, rather then the individual program, manages the graphics of the programs thats running.

Re: Xorg: What is it, and what does it mean?
 

Thanks, I guess I should have checked the ssh man page but I have been insanely thick lately.

The problem is I have been trying to do it without X forwarding, running the application on the server and telling it to output to the N900. I believe that should be a little faster over the LAN as it takes the encryption out of the picture. However there is not xhost command on the N900 so I can't tell it to allow the host a connection. I was thinking perhaps look for an Debian ARM version, but as I understood it usually its installed along with xorg itself which I do not want to risk breaking.

Its not vitally important, it just could be useful

Re: Xorg: What is it, and what does it mean?
 

KWrite ran beautifully over SSH, until I tried to type. I guess I hit the Nokia "lets fsck up the keyboard focus" issue. Its destroyed one of the big reasons I wanted the N900 in the first place, for X forwarding desktop apps.

Re: Xorg: What is it, and what does it mean?
 

easy-debian-chroot has a workaround for this issue now. So you can at least X11 forward properly from LXDE for now.

Re: Xorg: What is it, and what does it mean?
 

If I somehow manage to turn Hildon-desktop off as startup, what will I see? Will I be able to run X Terminal, at least (to turn Hildon back on with help of vi)?

P.S. You just said X.org provides GUI. So I can have GUI without Hildon-desktop, cannot I?

Re: Xorg: What is it, and what does it mean?
 

Acctually you would be more screwed if you deleted Explorer.exe than Xorg. Though just closing them would render the same thing.. they restart.
