OBLogout - replacement logout script for Openbox - Version 0.2 (Page 1 of 3)

Issue quasi-resolved by resizing the images, btw everyone.

I resized mine to half size and it's looking fine.

*screenie will be edited in*

Wow! I have just installed it, it looks amazing! I will try and test it out on a few more machines as and when I get chance.

Apologies for the minor cut out of the suspend button. This was caused by my mouse being annoying and not doing what I told it, so I ended up paintbrushing over that part of the image. I nvr noticed till I ran oblogout, and I'll fix it later. [=

edit: as I said, those have been resized. they are now 64x64 (so half the default size)

Andrew, cool. Downloaded, read README and ran

./setup.py install

and got an error. Shame on me for not looking at it closer. Setup.py exited with error complaining of permissions with /usr/lib/python2.5...blah blah blah. Me's thought "permission!" I'll show ya.

sudo !!

and whipped into submission it ran nicely. Sorry I didn't write down the error exactly and now that it is installed I can not reproduce the error. When I try reinstalling it now reports

changing mode of /usr/bin/oblogout to 755
error: /usr/bin/oblogout: Operation not permitted

Maybe the problem is unique to me but I thought you'd like to know. Installing with sudo worked for me.

installed on my eee pc 1000h, everything fits and works. Great job guys!

This looks really exciting.
I tried to install it but i got

wmdiem@diem-acer:~/openboxlogout-0.1-1$ sudo ./setup.py 
[('/etc/', ['openbox-logout.conf'])]
usage: setup.py [global_opts] cmd1 [cmd1_opts] [cmd2 [cmd2_opts] ...]
   or: setup.py --help [cmd1 cmd2 ...]
   or: setup.py --help-commands
   or: setup.py cmd --help

error: no commands supplied

I did ./setup.py --help and i didn't see anything important
I also read the README and it seemed to say I could just run setup.
Running the openboxlogout alone gives me traceback/misisng module error.

wmdiem@diem-acer:~/openboxlogout-0.1-1$ sudo ./openboxlogout.py
Traceback (most recent call last):
  File "./openboxlogout.py", line 28, in <module>
    from PIL import Image, ImageFilter
ImportError: No module named PIL

Thanks, can't wait to get it working.

EDIT: I went back and looked over the help, and noticed the build and install options.
Both return the same error:

wmdiem@diem-acer:~/openboxlogout-0.1-1$ sudo ./setup.py install
[('/etc/', ['openbox-logout.conf'])]
running install
running build
running build_py
error: package directory 'openboxlogout' does not exist
wmdiem@diem-acer:~/openboxlogout-0.1-1$ sudo ./setup.py build
[('/etc/', ['openbox-logout.conf'])]
running build
running build_py
error: package directory 'openboxlogout' does not exist
wmdiem@diem-acer:~/openboxlogout-0.1-1$

Mmm, very strange.

Ok, so heres some steps:

cd /tmp
wget http://assets.tensixtyone.com/releases/oblogout/openboxlogout-0.1-1.tar.gz
tar zxvf openboxlogout-0.1-1.tar.gz
cd openboxlogout-0.1
./oblogout

If that works, then:

sudo ./setup.py install

[EDIT]

INFACT, you've experienced a very odd error. What version of #! are you using? I suspect your missing a few python packages required for this software to run.

Ahh right, it's not tested on 8.04, so i'm not sure how to proceed.

I guess you need to sort the dependancies problem, so

sudo apt-get install python-imaging

And give ./oblogout a try.

So I came up with a kind of hack:
in openboxlogout.py I commented out lines 182-187

    # Set background color
      #  try:  
       #     self.bgcolor = gtk.gdk.Color(self.parser.get("looks", "bgcolor"))
      #   except ValueError:
       #     self.logger.warning(_("Color %s is not a valid color, defaulting to black") % self.parser.get("looks", "bgcolor"))
        #     self.bgcolor = gtk.gdk.Color("black")

The images are coming in as little error icons of some sort. Not sure what the deal is with that.
But on the plus side it runs.
Any idea how i could troubleshoot that?
I don't know python and I've never developed anything in a graphical environment, so I'm not sure where to start looking.

You could use PIL's histogram, you'd be able to tell if the background is light or dark and change the text color between black and white accordingly. some psuedo code following to base it off of:

hist = pilimg.histogram()
half = len(hist) / 2
text_color = "white"
darkness = 0
lightness = 0
for item in range(half):
    darkness = darkness + hist[item]
for item in range(half, len(hist)):
    lightness = lightness + hist[item]
if lightness > darkness:
    text_color = "black"

it's very basic brightness detection but it's a start. Also you would probably want to crop the detection area to the text area to improve detection speed.

sounds good, guess I'm just to used to the military trying to over-engineer a simple problem.

so, as I've said, I'm really impressed with the script, an I think it would be a great addition to future #! versions.
I would like to recommend, however, that suspend, should first start gnome-screensaver to lock the screen, so when the computer gets brought back it is locked. As it is, coming back directly into the last session from a suspend, seems somewhat insecure.
And lest I be one of those annoying people who just makes recommendations and expects everyone else to implement them:
I made the following changes from line 309 openboxlogout.py:

        elif (data == 'shutdown'):
            self.dbus_powermanagement.Shutdown()
            #os.system('gdm-control --shutdown && openbox --exit')
        elif (data == 'suspend'):
            os.system('gnome-screensaver-command -l')
            os.system('sync')
            self.dbus_powermanagement.Suspend(0)
            #os.system('dbus-send --system --print-reply --dest=org.freedesktop.Hal /org/freedesktop/Hal/devices/computer org.freedesktop.Hal.Device.SystemPowerManagement.Suspend int32:0')
            self.quit()
        elif (data == 'hibernate'):
            os.system('gnome-screensaver-command -l')
            os.system('sync')
            self.dbus_powermanagement.Hiberate()
            #os.system('dbus-send --system --print-reply --dest=org.freedesktop.Hal /org/freedesktop/Hal/devices/computer org.freedesktop.Hal.Device.SystemPowerManagement.Hibernate')         
            self.quit()

As you see i also added it for hibernate too, and threw in a sync for good measure (I want to know my data is saved, not just floating around in RAM).  Now when I suspend, it comes back up locked, which makes me feel good inside.
