error window
1) When I am running regular usermode krusader, and I click Tools>Start root
mode krusader, it asks for a password. I enter it, then krusader displays an
error:
Conversation with su failed.
(see attachment)
2) If I click Ignore, the error window disappears.
3) If I click OK, nothing happens. The error window stays visible. If I keep
hitting OK, the error window eventually disappears.
4) Then, I tried again. This time, strangely, when I hit OK, the root mode
krusader started up. This is rare. Usually the first result takes place.
5) I conducted a further experiment. In root mode krusader, I clicked
Tools>Start root mode krusader. A window appeared with a warning about how
improper operations in root mode can damage your operating system, etc. with
Cancel and Continue buttons. I clicked Continue, and another root mode krusader
window appeared, as expected.
6) I'm surprised that the warning did not appear after step 4.
I have noticed that krusader uses kdesu instead of sudo. I have encountered
this exact problem before, with another app that uses kdesu. I just wish I
could remember which one it is.
I created a workaround with useractions. The command is ssh-askpass | sudo -S
krusader -qwindowtitle. I put an icon for this in the toolbar. However, I would
like to correct the original problem in the first place, because, using my
workaround, when I invoke the root mode krusader, the root mode window's panels
don't reflect the panels in the usermode window that invoked it, which sucks
because I then have to set that up manually every time.
Is it possible to modify krusader in such a way as to switch from kdesu to sudo
internally?
