Switching to Lubuntu via installing it.

[Sslaxx]

Thinking of uninstalling GNOME/ubuntu-desktop and installing LXDE/lubuntu-desktop in its place. Just a couple of Qs. Got some hunches, just want to confirm/deny them:

* Does LXDE use GDM for login, or something else?
* Installing lubuntu-desktop would uninstall network-manager. Need to reboot if I do this, I take it?

Thanks.

* If you don't touch GDM.. LXDE will just be another entry in your session-list..
* I don't know.

Edit:

Thinking of uninstalling GNOME/ubuntu-desktop (..)
Just be sure you don't uninstall GDM, it that's what you want to use.. You know you can also use another loginmanager? Like SLiM (http://slim.berlios.de/) for example.

[Sslaxx]

Yeah, was going to check out GDM alternatives. Thanks for the tip.

lubuntu uses lxdm.

add the lubuntu ppa:
https://launchpad.net/~lubuntu-desktop/+archive/ppa

lubuntu is still work in progress, you'll need to work through things to make it work right.

you might as well just install a fresh lubuntu, it's easier to work with when there's no extra junk in the way. it's only like 300+mb
http://lubuntu.net/

i just got mine installed & i'm working out the kinks.

[julio.tomaschitz]

LXDE is very simple and light, great for using on usb stick, and old computers. there is everything you need to work and be alive. Well, my opinion: its the best cost-benefit.

[dzon65]

Mentioned this before.If you're planning to install lxde or lubuntu,you might wanna install thunar and use that as file manager.There's a bug in lxde/lubuntu.Don't think it's already solved,but it's impossible to set defaults (open a picture with...,open that kind of file with.....).Gdm is no prob.I've got lxde installed,but replaced lx panel with gnome panel (there's hardly any difference in cpu/ram) and pcmanfm with thunar.Besides those litle annoyances it's a great distro,very fast and a low footprint.(think I'm at 1.5Gb fully packed).

:lolflag: you still got that problem? cause mine is a fresh install of lubuntu alpha 3, just installed yesterday & i still can select my programs. :lolflag:

your desktop is looking sweet though!

edit: dude, i just spotted this, you can even select the program in properties.

[dzon65]

Hi there Kerry!Hmm,previous message didn't go through.Anyhow,updated and reinstalled lxde and yep,problem's still there.That's with the lxde-core,not lubuntu.Gonna give lubuntu a try.I'll let you know.

[dzon65]

Okay,tried lubuntu desktop.........same thing.Ah well,thunar's doing a great job.

[kerry_s]

Okay,tried lubuntu desktop.........same thing.Ah well,thunar's doing a great job.

maybe because your installing on top of ubuntu? i used the lubuntu alpha 3 iso, used the "startup disk creator" to get it on usb, then installed, i don't have a cd/dvd drive on my nettop.

i got mine going pretty good, cleaned up synaptic & fixed the quick search, installed maximus, turned off the decorations, even took the time to create a little gui for lxshortcut to make launchers, there should be a gui default, so made the script then used it to make it's own launcher. lol


#!/bin/sh

name=`zenity --entry --text="Enter a Name"`

if [ "$name" ]; then
lxshortcut -o $HOME/.local/share/applications/$name.desktop
else
exit 0
fi

the usual pics:

[dzon65]

This one's indeed on top of ubuntu.But,I did a minimal/lxde install on another pc with the same result.Tried before with the lubuntu iso and indeed,no prob there exept.....it was uninstallable.Gonna get me a new one and see how it turns out.Oh right,cd's....ran out of them.I'll let you kow..Like what you did with the launcher.

[kerry_s]

Like what you did with the launcher.

i'm going crazy trying to find what feels comfortable, i just keep moving things till they fit the way i work.

so i got 2 auto hiding panels now, 1 just for the desktop pager. ;)

[dzon65]

WOUHAHAHA.....Yeah,getting things right.Don't think it actually stops.Guess one keeps ajusting,there's always something "missing" or "to much".Have to hurry to back my stuff up.Quickly changing themes,icons,settings...you name it.The HD is on it's last breath.Quite frankly,I'm amazed it took sooo long.

[kerry_s]

i changed the lxshortcut script a little, cause my friend did not know exactly what it was for.


#!/bin/sh

name=`zenity --entry --text="Enter a Name (example: xterm)
this will not be the name shown, it's only for the *.desktop file"`

if [ "$name" ]; then
lxshortcut -o $HOME/.local/share/applications/$name.desktop
else
exit 0
fi


so it looks like this now.

[dzon65]

Hey,that looks nice!

[kerry_s]

i did a couple more for edit & delete to, just to make things easier after i had a couple of ooops, with bad command or just wanted to change the icon.

edit-launcher:

#!/bin/bash

scan=`ls $HOME/.local/share/applications | grep .desktop`
selected=`zenity --list --column=" " $scan`
lxshortcut -i $selected


delete-launcher:

#!/bin/bash

scan=`ls $HOME/.local/share/applications | grep .desktop`
selected=`zenity --list --column=" " $scan`

if [ $selected ]; then
rm $HOME/.local/share/applications/$selected
zenity --info --text="Launcher removed"
else
exit 0
fi



it would have been nice to have been able to select where in the menu we wanted it, everything goes under "Other", my list might get long. :-|

[dzon65]

Kerry.If I understand it correctly,you want to add it as a seperate menu?This was used to add a menu for the gdm/splash tweaking in karmic.Don't know if it helps but might inspire.
1) Install the script (or a wrapper for the script) in a bin directory.
Code:
install gdm-setup /usr/bin
2) Put a Desktop item in /usr/share/applications/gdm-setup.desktop

A typical example of it's contents:
Code:
[Desktop Entry]
Version=1.0
Name=GDM2 Configuration Tool
Comment=Tool for editing Login Window
Categories=Application;System;
Exec=/usr/bin/gdm-setup
Terminal=false
Type=Application
And it should appear in Applications->System->GDM2 Configuration Tool (by the guy formerly known as tinivole)

[kerry_s]

no, thats not what i mean.
i wish the lxshortcut gui would also do "Categories", i know i can add it manually, but that would not be user friendly. i think i will add that feature to the script, it should be easy enough using the "echo "Categories=$section;" >> whatever.desktop" i'll play with it later i just got up & got to cook breakfast for the kids, but i need some coffee & a cig in me first, it's also shopping day so got to get groceries. basically when i can, i'll get to it. :lolflag:

it should take like less then 5 minutes to add to the script to get that feature, but i was to tired yesterday, i really didn't think about it.

[dzon65]

Been playing around with slitaz running in ram.That distro's been lying around and I didn't pay much more attention to it.Gave it another try and WHAM!This is lightning fast.(totally forgotten about it)Major drawback:screenresolution's only up to 1024X768.Found out why.Default setting is with the xvesa server,so need to install xorg.Wonder if the speed will decrease a lot though.But,that's for tommorow.
Oh,btw,good morning!

[kerry_s]

all right my friend revision #3 for the make-launcher, now you can can choose what section of the menu you want it to show in.
i went with a list instead of manual input, i hope i got most of the sections.

menu-launcher:

#!/bin/bash

name=`zenity --entry --text="Enter a Name (example: xterm)
this will not be the name shown, it's only for the *.desktop file"`

if [ "$name" ]; then
lxshortcut -o $HOME/.local/share/applications/$name.desktop
select=`zenity --list --text="Choose the Menu Section" --column="" Utility Graphics Network Office AudioVideo System Settings Other`
echo "Categories=$select;" >> $HOME/.local/share/applications/$name.desktop
else
exit 0
fi

[kerry_s]

here's the new edit-launcher with the menu categories selection, so if you need to you can.

edit-launcher:

#!/bin/bash

scan=`ls $HOME/.local/share/applications | grep .desktop`
selected=`zenity --list --column=" " $scan`
if [ $selected ]; then
lxshortcut -i $selected
select=`zenity --list --text="Choose the Menu Section" --column="" Utility Graphics Network Office AudioVideo System Settings Other`
echo "Categories=$select;" >> $HOME/.local/share/applications/$selected
else
exit0
fi

[kerry_s]

you know what, i think i'll just combine all 3 scripts into 1 script where you select what you want to do, that way it will be easier to manage & make changes. i'll get on that later. ;)

[kerry_s]

okay this is it, the lxshortcut launcher to provide a gui way for the user to work with launchers. i keep my script in $HOME/bin, but you can put yours where ever you feel like. you can run the script itself to make the menu launcher for the launcher. :)

Lxshortcut Launcher:



#!/bin/bash

# this is a script to add some gui features to lxshortcut for a more user friendly experience
# created on lubuntu 3/19/2010
# it's a script to fill a need, you may do with it as you please
###

## this part is the choices to choose from ##

chose=`zenity --list --title="Lxshortcut-gui" --column="" "Make Launcher" "Edit Launcher" "Delete Launcher"`

## this part makes the launcher ##

if [ "$chose" = "Make Launcher" ]; then

name=`zenity --entry --text="Enter a Name (example: xterm)
this will not be the name shown, it's only for the *.desktop file"`

if [ "$name" ]; then
lxshortcut -o $HOME/.local/share/applications/$name.desktop
select=`zenity --list --text="Choose the Menu Section" --column="" Utility Graphics Network Office AudioVideo System Settings Other`
echo "Categories=$select;" >> $HOME/.local/share/applications/$name.desktop
else
exit 0
fi
fi

## this part is to edit the launcher ##

if [ "$chose" = "Edit Launcher" ]; then

scan=`ls $HOME/.local/share/applications | grep .desktop`
selected=`zenity --list --column="" $scan`
if [ $selected ]; then
lxshortcut -i $selected
select=`zenity --list --text="Choose the Menu Section" --column="" Utility Graphics Network Office AudioVideo System Settings Other`
echo "Categories=$select;" >> $HOME/.local/share/applications/$selected
else
exit0
fi
fi

## this part is to delete the launcher ##

if [ "$chose" = "Delete Launcher" ]; then

scan=`ls $HOME/.local/share/applications | grep .desktop`
selected=`zenity --list --column="" $scan`
if [ $selected ]; then
rm $HOME/.local/share/applications/$selected
zenity --info --text="Launcher removed"
else
exit 0

fi
exit 0

Hats of Kerry!I'm trying to get this slitaz working properly.It comes with lxde,openbox.....well,same as debian/lxde,only..faster.Gonna install it as only os on senior (that's a good resolution,damn,wish I could get the settings right on my laptop) and gonna use your script.You should post this as a tutorial or on the lxde forum.Think a lot of people could benefit from this.(from?.....my english is not really what it's suposed to be,Papua?).

the scripts not perfect, my friend mentioned a problem with the echo command, if you edit a launcher you'll end up with "Categories=*;" listed several times in the file, not a problem as it uses the last 1, so the script still works, but it's messy. i tried using sed, but i can't get it to write to the file, my programming skills are very basic at best, but i can read good, so i manage. :lolflag:

i'm not to worried about posting it all over, if a person uses google to search "lxshortcut gui" we're at the top of the list. ;)

[earthpigg]

kerry,

that looks great!

you wouldn't mind if i tested/used/modified that for the next Masonux release would you?

want to formally declare a license? (GPL, public domain, BSD, etc)

[dzon65]

Djeez kerry,seriously?...................quote:"my programming skills are very basic at best".Earthpig has a point.

earthpigg, like it says do with as you please.
grab the 1 from here:
http://ubuntuforums.org/showthread.php?p=9000663#post9000663

i fixed it so the "Categories=*;" aren't duplicated in the edited launcher and i add height for less scrolling. enjoy!

i feel pcman done most of the work with lxshortcut, but why he just stopped short of a gui is beyond me, any kind of gui, i would even be happy if the gui was made with xmessage, it would be ugly, but still at least a gui. :lolflag:

[earthpigg]

sweet. if anyone wants to make it a more 'native' part of their system, just toss it in /usr/bin and make it have the same permissions as the rest of the stuff in that folder.

0 - to uphold convention, rename it from .txt to have no extension. i called the file 'lxshortcut-gui'.
1 - sudo pcmanfm. or thunar, or whatever.
2 - drag+drop it into /usr/bin
3 - right click, properties
4 - make it have permissions identical to everything else


done.

now you can type lxshortcut-gui to run it... and promptly use it to create a menu entry for itself with the command "/usr/bin/lxshortcut-gui" as a test run.

try all 3 features let me know what you think, it probably could use some titles for the windows, i run nodecor so didn't bother, the scripts simple enough i'm sure can add them if you want. :)

[earthpigg]

they all seem to work. different versions of lxpanel that ship with different releases of ubuntu have different menu sections, so ill probably modify them accordingly when we see what ships with 10.04.

if i do end up playing with it, ill be sure to post it back here. (i commented my local copy of it to remind me :P )

[BrokenTusk]

Okay Kerry_S. Hey guys.
I toyed with Kerry's lxshortcut script and it became the LxMenuEditor.
LXDE is already fast, but wait till you clean up the app launchers... wowee!
I sincerely hope it boosts you all into warp speed too,
