[trick] Leave console free for apps while running X


This is good:

startx &

Now you have a free console.

Better:

startx &> /dev/null &

No messages.

Now you can switch console/X session pressing Ctl+Alt+[1-6] and Ctl+Alt+[7<]

Cheers!

vfs.

yes, if you use the ampersand ( & ) after running a program from the console or command, it runs it in the background.. now do you know how to bring it back ?

Uh, tried to fool me?

Just type in:

jobs

look which number is 'startx' then:

fg number

Ta-da!

Try this too:

startx

Now press Ctrl+Z and startx is in the background, leaving the console free...

regards,

vfs.

Ok, I just posted because YOU and YOUR friends must know EVERYTHING about Slackware, but there are lots of newbies in this forum.

I posted for THEM, NOT exactly for YOU, ok?

well they are not specific to slackware at all. i'd recommend similar posts go in the "linux - general" forum.

eehrm... i think that is not quite correct.
When you press CTRL+Z, startx will not be run in the background. It will be paused (at least the console says 'stopped'). You have to type: 'bg' (background) to unpause startx and to run it in the background. So CTRL+Z is not enough to move your startx into the background.

BTW: if you want to pull startx out of the background, just type 'fg' and it will return to you

Bringing X Back to Forground

The question that begs to be asked is, why would anyone *want* to bring X back to the forground? It's not as though it had any interative feaures. (If I'm wrong about this, someone please enlighten me.)

To theguide:

I think so...

But, at least in my system, when you 'ps ax' you see X with a '?', quite like a daemon. There's no need of 'bg'. I can even log out and X continues running.

I don't know the X internals, but I think related to the server+client arch...

to acid:

Or maybe it could be easier to 'killall xinit' or 'startx'.

well yeah a kill -9 or something would be easier... just a potential reason.

You have no chance to survive, make your time!

I don't understand the > /dev/null & part of startx &> /dev/null &.

Also, acid_kewpie: why, as a moderator, would you discourage people from posting tips saying, "we do know all of these tips"?... as if everyone who enters this forum already knows all linux tips. I do agree that these particular tips are better posted in the general linux area though. I just don't understand the point of a moderator trying to make people feel dumb for posting something they apparently consider to be elementary. It would stand to reason that a lot of posts on a BBS for questions about a particular topic would involve subjects that the moderators already know in detail. That's one big reason for having moderator status. Anyway...

> /dev/null

/dev/null is a special device that goes... absolutely nowhere, the big bit bucket in the sky. (It's also a great device to use for backups. Guaranteed, backups will go many times faster.).

X outputs all kinds of status messages all the time. This can be useful for debugging when something goes wrong, but would make running X in the background almost useless, because the console is getting bombarded with the status messages. > is used to redicred standard output. In this case, we are redirectiong to /dev/null (quietly disposing of all the data.). Alternatively, you can redirect data to a file to keep a log (or for programs that output to STDOUT and you need to capture it)...
> /somedir/somefile.. Note that as well as STDOUT, there is also STDERR where most programs will send error messages. These are redirected independant of STDOUT with 2>.. for example: startx > /dev/null 2> /somedir/error.log

And finally, you only need one & for the whole thing.

startx > /dev/null &

of course people are perfectly free to post useful tips and such, but, being a continually changing forum, tips and such always sink without trace within a very short period of time. some point last year one guy took it upon himself to write a series of lengthy FAQ's that were quite good actually, but naturally as VERY few members ever use the search features on the site it dissapeared within a day.

In actual fact in a short while a few extra features are gonna be added to the site for tips and tutorials and stuff that will hang around permanently. I'm sure contributions will be welcome.
