warnings when running sudo under kubuntu

[John Batt]

When running KDE apps from konsole I get the following:

Link points to "/tmp/ksocket-root"
Xlib: connection to ":0.0" refused by server
Xlib: No protocol specified

kdeinit: Can't connect to the X Server.
kdeinit: Might not terminate at end of session.

Although the apps don't crash and appear to function normally
something is wrong. Again this happens when running KDE apps from Kubuntu 6.0.6.

This happen with ALL KDe apps. This particular instance was from running:

sudo kate

it also happens when running Kate as normal user.

Up to "Failed to open device" this is a duplicate of bug #42553 , however, as for the other messages, I am not sure at all.

Could you do any of the following:

1) Update to Edgy.

2) comment out in /etc/X11/xorg.conf:

        InputDevice "stylus" "SendCoreEvents"
        InputDevice "cursor" "SendCoreEvents"
        InputDevice "eraser" "SendCoreEvents"

3) Post the output of "kate", "sudo kate" and "kdesu kate".

Thanks in advance.

Than you for this bug report. Unfortunetly, this happens for all applications because applications are to be run as "kdesu <app> in the run command (in the K menu). This is the proper way to run the command as super user graphically.

[Manuel López-Ibáñez (manuellopezibanez)]

Freddy, I am not sure with which authority you close the bug, so I am not going to reopen it again but I completely disagree with your analysis. Yes, a workaround is to use kdesu but it is cumbersome and actually most KDE applications work nicely even if you use sudo directly (althougth they print a lot of nonsensical warning messages).

At the very least, the warnings are more scarier and unhelpful than they should be. If kdesu is truly the only way, then the warnings should say so. Otherwise, this is a bug with an easy workaround (use kdesu) but still something that could be improved.

Thanks and please reconsider re-opening it so perhaps someone will decide to work on improving the situation.

[Rich Johnson (nixternal)]

manu, you are correct. I am reopening this, confirming it, and adding it as a wishlist item at this time. I think there should be more helpful warnings as well, at least a message that says "Since you are opening a GUI application in KDE, you should utilize the 'kdesu' command instead (i.e., kdesu $command)"

[Freddy Martinez (freddymartinez9)]

On closing the bug, I realized that the output should be as Richard suggested. However, I assumed it was a known issue that was being worked on so I went ahead and closed it. Hopefully that clears up why I closed it.

[Manuel López-Ibáñez (manuellopezibanez)]

Anyway, I still think there is a better solution to giving a better warning message.

Kdeinit should be sudo-aware. Kdesu is an ugly hack to the problem that KDE applications are not intelligent enough to realise that they are running under sudo. I don't say it is a simple problem to fix, but if sudo is the future, then it would need to be fixed eventually.
