[Bug 50971] Re: kdesu will not start apps

[kko]

"A workaround is to run 'sudo rm /var/run/sudo/yourusername/*'."

...except that you can't do this, because the shell fails to replace the
"*" with the correct filenames (it doesn't have read permissions to the
directory). You would have to do a 'sudo ls' on the directory and remove
each timestamp ticket separately, manually entering the correct
filename.

The following works better:
'sudo su'
'rm /var/run/sudo/yourusername/*'
'exit'

About other workarounds (from bug #72545):
 - Opening a couple new instances of Konsole occupying some new pts's should normally help.
 - Also, you can set the option "timestamp_timeout=0" in '/etc/sudoers', which will force 'sudo' to always ask for the password.
