Desktop is being blocked - neverending story

[krishna.murphy]

Did you just boot a CD/DVD, do an install to hd or flash, or are you using the "poor mans install?" If you have a "persistent store" (or full hd install) then whatever changes you've made (Polish keyboard?) most likely are causing the trouble. If not, it's got to be a hardware issue or a bad disk, I guess.

My suggestion, absent more information about the specifics, would be to boot a CD and see if the problem is solved. Assuming that's so, then you have some kind of persistence; so, you can either try to repair by changing the things you've been working with back to the default or (best looking to me) just dump the persistent store and then start over, making the changes you need step-by-step, monitoring for the problem you've been having as you go. You will, of course, want to preserve any files you created for future reference/use to create the system you desire and keep any documents, etc. that are stored within the permanent store.

Cheers!

p.s. You can also try disabling Compiz (the fancy desktop effects package) by using the cheatcode:

knoppix no3d

for diagnostic and/or further use purposes.

I started just my sys by full HD install. No polish keyboad (I didn't knew it exists 2 month ago . then I've lost DVD access, permissions and so on, by clicking or loading some keyboard shortcut, don't know which. Compiz doesn't load automatically, but every time I put something from my Cell phone on the dekstop something changes and I see miniatures I see more like variable desktop icon positions I can change and it;s good, but when I unplug my USB, everything changes back

How could I lost my permissions when I didn't had them at the begginning?

My disc is good, I've checked him.

Anyway, I can't start over, cause I watch movies ad I have no other external to collect and store them. I use Knoppix since 2 months and the problems started in the first 2 weeks ...

I assume I used some keystroke with Shift or Fn on my laptop, so I lost my provileges.

Every time I go inside into "Skin Selector", I see an error, that Gnome can't be run? Anyway, the skin shows. The skins have folders like Metacity and Gnome, but there is no KDE. I don't know that much what it is, what it does and what happened.

Can you check your permission for the Desktop folder /home/knoppix/Desktop - the Owner should be knoppix with group knoppix and owner should have full read,write and execute permissions for this folder. May be you simply have changed the permission for your desktop. This is just a guess

[GizmoPlushie]

I can check it, sure. TOday I'm at work and it's 10 a.m. so I think in the evening I'll check and tell you.

But I think it's rather I changed desktop permissions somehow, maybe by some keyboard shortcut.

Ps. How can I check permissions with right click when I can't use right mouse click on the dektop?

[mecho]

In terminal
ls -ld /home/knoppix/Desktop

You should see something like this:
drwxr-xr-x 2 knoppix knoppix 4096 May 25 07:09 /home/knoppix/Desktop

DRWXR means - D - directory R-read W-write X-execute for owner
XR is read and execute for the group and for other users. If you see this it means your permissions are fine

Let's assume settings are fine and I mistakenly - as a newbie - changed them to another more limited group:

So,

1). Is it possible to change it back?
2). Will it restore desktop icons / root folders - functionality? (like drag and drop icons, see them like miniatures and the most important: right click on the dekstop?)
