How do I stop users from changing their background? I'm installing ubuntu on some (non-networked) computers at my school, and I don't want the students to change the background on the desktop. I don't care if they change it during their session, but it must revert to the default when the session is logged-out or shutdown.

But i found one annoying thing, when we change background of the top panel, it does not change background of the menu (Applications Places etc).Actually I have shifted the top panel to left, It doesn't look good due to repeating background image vertically
View 3 Replies View RelatedBeen trying to get mac4lin to work, and in the process, I attempted uninstalling, rebooting, then reinstalling gtk-engines-pixbuf. This has now screwed my system so that the background is a light grey and any attempt to change the wallpaper just makes X crash, forcing me to Ctrl Alt Backspace. I'd rather avoid a reinstall of the system since I have it customized to my needs, so is there a solution to this? I tried reinstalling the pixbufs package, but no dice.
View 1 Replies View RelatedI was configuring the vnc server or remote desktop using the "gconf-editor" -- "desktop - gnome - remote_access" pane, and first I clicked on "disable background" to see if it was usefull or not to disable it (in terms of speed). It worked fine but sometimes when closing the connection, the background refuses to reenable, mantaining the black background...
That's ok, I decided to disable the feature and share via vnc the background as it is a wired net and I do not really need this feature.
My surprise is that now, whith the feature DISABLE (box unchecked), I cannot set a background, it is always black and I find no way to go back in this...
is this common, or something that can be "easily" fixed?

I am extremely new to Ubuntu (mainly a Windows person) but am trying to create this environment to give our students an option to boot either into Windows or Ubuntu.
I know how to change the colors of the panels. But on the parts were the ubuntu symbol, the menus (Applications, Places, and Systems), the date and time, and the indicator applets is, they do not change at all. And pretty much the same problem on the bottom panel.
I tried Gnome color changer but only works for the texts and the drop down menus. I use Gnome classic (hated Unity). My goal is to make ALL of the panel background black.
I want to change the color of the background in this window (see screenshot)without changing themes. Whats the best way to do this?
View 9 Replies View RelatedI do need to change or edit this white Ubuntu logo on the black background that comes right after GRUB and before my xsplash is played. How do I do that? Where is that picture saved in the system?
I have edited my xsplash the way I want it by changing the pictures in /usr/share/image/xsplash but cant find a way to edit this other bootup screen.
After much searching and trying of more complicated methods for changing the GRUB-PC background image, i found method that seems to work. The simplest one! I installed grub2-splashimages, which created a new folder in /usr/share/images, called grub. From there it appears to be as simple as adding the image of your choice, then adding "GRUB_BACKGROUND=/usr/share/images/grub/your_image" to "/etc/default/grub" file, the running "update-grub", of course.
Only problem is it doesnt work for the image i really want. So my question: What qualities should an image have if it is to be successfully used as a GRUB-PC (GRUB 2?) background? I have read that you do not need to resize the image anymore, indeed i tried resizing it to match the size a default image form the "/usr/share/images/grub" folder , and saving it with the extension .tga in Gimp and it did not work. The image i want to use is quite large, it is also black and white/grey-scale and in the .png format.
I want to change the background image for a Plymouth theme on FC13. I'musing spinfinity and I'd like to just have a blank background or somesolid color rather than the Fedora logo. I've found the sprites in /usr/share/plymouth/themes/spinfinity.

View 1 Replies View RelatedI added an entry to grub's menu.lst and reran grub (grub-install hd0) and now my background is gone and the entries just show up like on a normal console.
I searched the forums and I couldn't find anything. Does anybody know why this happened and how to fix it?
I have not changed anything in menu.lst except for adding the new OS.
When I start Ubuntu, file explorer windows look like they should.

I am using Ubuntu 11.04 as a guest OS in Virtual Box 4.0.12
im looking at changing the computer systems over to Ubuntu, at a scout campsite im staff at. i have sorted some filtering out with dansguardian.
but how do i limit the powers of users, so remove all the administrative side and most importantly stop a user changing the network proxy setting.
i have used ubuntu before but not for a while, so im a bit of a newbie atm.
I use the following method for preventing the users from changing their passwords , is there any other method other than this ?
ls -l /usr/bin/passwd
-rwsr-xr-x 1 root root 37140 2010-01-26 12:09 /usr/bin/passwd
so we need to remove the suid for that command as follows :- chmod u-s /usr/bin/passwd now normal users won't be able to change their own passwords - and only the root user will be able to do it for them.
I'm just getting started with postfix for the first time (using courier pop) and everything is working well. However I can't seem to figure out how to only allow some system users to have mailboxes?
For example I have a few accounts which are FTP only accounts but they still have mailboxes under postfix? Is there any way to tell postfix the accounts that I actually want mailboxes for?
Also on a side note, I notice that mail seems to be stored under the user's home directory. I'm scared they may accidentally delete them.
I am on ubuntu server and its joined to an W3k Domain thru winbind/samba. However everything works fine and Windows and Local users can login to the machine without any problem. However when I wanted to create a local user X and change his password I couldn't. It created the local user X but I could not change the password.
View 1 Replies View RelatedI am administrating a system with about 40 or 50 users, and we recently jumped ship from windows to ubuntu. Most of my users are getting along fine, but it seems every few days, i have to help someone who accidentally changed something, and now their account (or more rarely, the machine) is unusable, and has to be reset.
I know configuring /etc/sudoers is a huge step toward fixing my problem, but that still will not completely solve it. What I would like to do is prevent users from making ANY changes to the system (aside from their work files and the like), including themes, icons, desktop, background, etc.
I'm still working on ubuntu 9.10 with an acer aspire 1810tz. To use my microphone I found out that I have to change my microphone settings because it's mono and the default setting is thinking it's stereo: With the Volume Controller I setup one chancel to 5 and the other to 90 and the mic is working fine. Starting Skype and using it I see that the setting is reducing the volume for the mic below 20, so nobody can hear me. I tried closing first Volume Controller and then starting Skype, no matter the volume of the mic is reduced. How do I stop this behavior?

View 6 Replies View RelatedI want the users to access servers via ssh public key only. By default they don't know their initial password and do need to change that when performing administrative tasks.For changing their passwords without knowing the old they need to switch to root for this special case.The only case it seems I don't have control is that users can not only change their password but also the password of other peoples. Does someone sees a solution (without apparmor/selinux and special /usr/bin/passwd.sh) to restrict users to only change their password?I miss the feature of using environment variables in sudoers file.

View 8 Replies View RelatedI have a Ubuntu 10.10 server; I have created several users and wish them to have their own web space (with a unique domain name for each). I have therefore created www folders within their home folder and created new Virtual Servers to host each domain name and point to the users www folder in their home folder. They can then use an FTP client to upload files. This all works well.
However, I would like to stop a user from going back up a level and traversing the tree.They can currently go back up to /home and see other users names.
