su takes a long time to come back

[cfli1688c1]

just recently, i notice that when i type su in the command prompt, it takes a long time to come back, at lease 10 seconds.

the only thing i can think of that might affect this was that i change my desktop to gnome, but i changed back to lxde.

anyone have any idea why would su take such a long time?
if i do a sudo command, it execute immediately.

thanks.

Are you using Knoppix 7.5? If so, It's not the only well known bug of this version and there are not yet solutions for these.

i am on 7.4. It did not do that when i first did the hd install. only recently. what should i look for to see what is causing this delay? thanks.

i forgot to mention, it also too a long time when i try to shutdown the pc from the knoppix menu with logout, it also took a long time to ask me what i want to do, shutdown, logout, etc.

That's also a bug of V7.5. Did you some update or upgrade in your HD installation?
