change screen logo on login settings in 10.04

Have you tried logout and see the new logo?

Yes, I tried it, but it's the same thing :/

When I change logo, quit Ubuntu Tweak, and restart it, the new logo goes away (there is the old logo) !

If it can help you, I have passed in Lucid Lynx from Karma with update and no format and I discovered a problem in gconf key in a software (cover thumdnailer), because it take one key that had disapeared ! (I had to apt-get remove --purge) to have the solution.

Perhaps my file of gconf is destroyed ?

I think so.

And I recommend you to reinstall gdm. Try this command in terminal:

sudo apt-get install --reinstall gdm

After this step, try again in Ubuntu Tweak.

I did "sudo apt-get install --reinstall gdm" but no, it's the same thing.
I change the logo, quit Ubuntu-tweak, restart it, and the original logo is here ! :(

It's strange because there is not button to save my setting...

It takes effect immediately, so there's no button to save your setting.

Try to run Ubuntu Tweak in debug mode and change logo. Give the the output. Thanks.

Use this command to launch:

ubuntu-tweak -d

Ok so with this command :

quit and restart ubuntu-tweak :

The log seems nothing wrong.

Try to do this command:

sudo du -hs /var/lib/gdm/.icons/LoginIcons/apps/64/computer.png

$ sudo du -hs /var/lib/gdm/.icons/LoginIcons/apps/64/computer.png
[sudo] password for yo:
du: cannot access `/var/lib/gdm/.icons/LoginIcons/apps/64/computer.png': No such file or directory

Thanks for your confirm. I know what's the bug now.

Because the path "/home/yo/Documents/fichiers de conf/Yop69_64x64.png " has space. Try to move your "Yop69_64x64.png" to other folder without space in the name, and change again.

I will fix it soon.

Ok Thanks !! it works \o/

Hi,
I'm having problems with the same icon. I've tried to see if it overwrites the one in /var/lib and it does that. Unfortunately, at login screen, I still got that boring computer icon.

I tried to reinstall gdm, manually copy a 64x64 png to /var/lib/gdm/.icons/Foxtrot/apps/64/ or a .svg, I tried using Ubuntu Tweak, but the logo still doesn't get loaded. Do I have to reboot?..or logout and login is enough? Maybe I have to mention that Ubuntu Tweak is always showing the right icon, gdm on the other hand, doesn't.

I'm using Xubuntu 10.10. Ubuntu-Tweak does allow me to change the wallpaper for the login screen but for some reason I am unable to change the logo of the bloated pig corpse that xfce uses. I have converted a jpg to png in gimp and shutter, resizing it to 64x64. When I log out and back in there is just a black square with a line through it showing no icon was available.

Follow-up to my last post. I resolved the issue. It was as simple as adding reading rights to Others and making sure the icon was in a non-encrypted location. I suggest that a text label is added to the Ubuntu-Tweak login customisation page to tell the user more information on where to place the icon and what permissions it needs.

Thanks for your information.

So you use the encrypted fs with Home, right?
