pkexec fails to launch apps as root

[Arjen Balfoort]

I could fix mousepad with:

Code: Select all

sudo cp /usr/share/polkit-1/actions/org.xfce.thunar.policy /usr/share/polkit-1/actions/com.solydxk.pkexec.mousepad.policy
sudo sed -i 's/thunar/mousepad/g' /usr/share/polkit-1/actions/com.solydxk.pkexec.mousepad.policy
sudo sed -i 's/Thunar/Mousepad/g' /usr/share/polkit-1/actions/com.solydxk.pkexec.mousepad.policy

I could provide the file with solydx-system-adjustments-10, alright?

Looks like that would work, yes.

Curious that mousepad doesn't have a polkit file of its own. Thunar has a context menu entry "open editor as root", so I would have expected some mechanism to handle that. I don't use thunar or mousepad, so I have never come across these issues and simply assumed it 'just worked'...

Just FYI, either on the PC at work (just updated straight from solydxk-system 3.3.0 to 3.3.5) or on my 2nd home laptop...

Reverting back and I get these problems in SolydX 10:

gedibi doesn't work from within Thunar.

... I don't have any error with gdebi, either standalone or from Thunar (or even from Caja for good measure)!?
However,

Mousepad

Code: Select all

$ pkexec mousepad
Unable to init server: Could not connect: Connection refused

(mousepad:2782): Mousepad-ERROR **: 18:27:47.836: Cannot open display: 
Trace/breakpoint trap

I do get the second part of the error, but not the first one ("connection refused").

I updated gdebi to fix launching from thunar yesterday evening.

I've also updated solydx-system-adjustments-10 to address mouspad not having a policy file. This should solve your issue with mousepad.
