Lyrositor's questions

I have enabled icons in menus, and most of them show up well (folder icons, file icons, save icons, etc.). But whenever an app tries to use an icon specific to itself, such as GIMP, it replaces that icon with the app icon, so that when I look at a menu in GIMP, I see most of the time just icons of GIMP's logo (that seems to be the only problem; the text is fine). I thought this was proper to GIMP, but I also noticed it happening on AbiWord.

Thankfully, as I said, it's not for all icons. But it still bugs me. Why is it so?

Here is a screenshot of a menu in GIMP:

I am using Ubuntu 11.04 Natty Narwhal, with Unity desktop (the problem also occurs on the Classic desktop, if I remember correctly).

EDIT: This does NOT occur on the Classic desktop; only in Unity.

I used to be able to connect to wireless networks and wired networks (although my wireless network had problems; see my other question). Then, one day, the section Wired Networks just disappeared! And when I plugin a cable, nothing happens! Why?

Despite having worked a while, the answer below seems to have stopped working for me. Therefore, my question is still active, and I anxiously await any replies.

I want to remove the MeMenu, without removing the logout/shutdown/restart/etc. button next to it. I never use social networks, so I have no use for this function. Any tips?

I'm planning to maybe install Ubuntu server on an old machine. But my question is: can I install Ubuntu server on a machine and have it connect to my home network - wirelessly? I can't use a cable in this case.

I'm setting up a new user account, and I want to allow access to only certain programs for just that account. How would I go around doing that?

I guess some of the screensavers in Ubuntu are nice. But I'd really like more. Is there a website with screensavers for Ubuntu?

Also, I am particularly looking for a screensaver that looks a bit like Mac's ribbon ribbons of light thing.

Ever since I installed 10.10, the network applet stays with a red exclamation point for about 10 seconds. I don't know why this is happening. Please help me, this is very annoying! I didn't have this problem when I was with 10.04. EDIT: I should maybe mention the indicator appears, but it says that there are no network available. Only after the aforementioned 10-15 seconds does it detect all the networks.

EDIT 2: This question is not answered! I have tried with another computer, and the network manager is already loaded upon login, so I know it's a bug. Please help!

EDIT 3: I have the same problem with my power indicator, actually...

EDIT 4: The problem is back once again. I have counted: it takes a full 15 seconds to load after my desktop.

EDIT 5: I have filed a bug report in Launchpad here. Can ANYONE help me?

EDIT 6: Still nobody?

I have Ubuntu 10.04 on my computer, with Windows 7 next to it. Instead of upgrading to 10.10, I feel like doing a clean install. However, I don't want to erase my Windows, even though I barely ever use it. My question is: how would I remove Ubuntu 10.04 from my drive and install Ubuntu 10.10 in place, without losing any space or anything, or losing Windows 7?
