HPLiP / HPLiP toolbox : broken in Budgie?

Coeur-Noir · December 1, 2019, 2:50pm

Hi,

was trying to troubleshoot an old HP4180 deskjet AiO printer, so I may need HPLiP utilities.

HPLiP is a Qt4 app and looks like this on Unity16.04 :

It’s also a kind of indicator in the tray.

Am on UBudgie 18.04 and it looks like this, too big, almost impossible to move around and missing core elements :

Note also after I’ve tried to launch it on Ubudgie18.04, all desktop became almost unresponvive :

see « unable to grab cursor » in terminal, as I was able to move mouse cursor but click was uneffective.

HPLiP is THE tool regarding HP printers, I know it’s not your fault if it’s written in Qt4 but maybe find a workaround ? Or may I miss some packages ?

On the same machine, booted on same kernel, same base system 18.04, but with another user and Unity DE :

So there’s something in Budgie that prevents HPlip gui from working ?
And it also seems I do not miss any package regarding qt4 - that would not work either in that Unity session.

18.04 UB here - I’m seeing this

Same screen with 19.10

O.o damn… so where to look for ? And look for what ?

Have a look at the .desktop file in /usr/share/applications.

Look at the exec= line.

Run the command after exec= in a terminal.

Any messages displayed that may give a hint to what the issue is?

Try this:
sudo apt install hplip hplip-gui hplip-data hplip-doc hpijs-ppds libsane-hpaio printer-driver-hpcups printer-driver-hpijs.

As stated above, hplip gui works in an another session ( unity ) on that same machine and system so I don’t think packages are missing. Will check anyway.

Still the same problem. Notice also that once hplip tools is open I can no longer use the printscreen key and all interaction with Budgie shell ( panels, window controls ) become slooooow, and the icon in systray displays no menu at richt or left click. Have to use the system monitor to quit hplip.

Hmm, it seems to be an issue with the GTK2 style for Qt. Get Qt5ct (sudo apt install qt5ct), also see Can't use Qt5ct to change global application style to kvantum.
open qt5 settings from the menu, and change the style (to e.g. fusion). This will temporarily make qt5 apps use an old style. Afterwards, try again. If the issue is solved, I recommend you install Kvantum ( https://github.com/tsujan/Kvantum/tree/master/Kvantum) and choose one of those themes

I am using Pocillo gtk theme with Pocillo icons … if you are not using those does switching to Pocillo make a difference?

Coeur-Noir · December 1, 2019, 11:17pm

I thought I had mentioned it already or maybe I did not edit my first message.

It behaves exactly the same with default pocillo theme / icons / widgets. Here on another user with default settings :

( by the way that picture also illustrates the problem about overlapping panel / height mismatch, see Top horizontal panel overlapping, if height < 41 px ).

Am I missing some package⋅s in the gtk realm ?

Or do I have too much here ?

Coeur-Noir · December 1, 2019, 9:57pm

Mmm… I really don’t think it’s a problem with Qt since it works in another session / another user on the same base-system but another DE ( Unity instead of Budgie ).

Maybe the problem is here : do you know if Budgie and Unity live nicely together on the same system ( but separate users ) ?

fossfreedom · December 1, 2019, 9:59pm

So if you use the unity user but login to budgie desktop what happens?

codic · December 1, 2019, 10:04pm

It seems to be the problem, if i understand you installed unity on UB and the application launches on UB, or do you mean you have a dualboot system with stock Ubuntu and Unity + UB?
(UB=Ubuntu Budgie)
It does seem to be a user config problem

Coeur-Noir · December 1, 2019, 10:55pm

My religion forbids me to use more than one DE by user, lol !

Joke aside it’s the best way to have mismatching config’ files regarding DE.

But I don’t care to break my Unity session now as it’s almost empty.

So, logging with Unity user but in a Budgie session gives that :

where you can clearly see the mismatches between unity config ( ambiance theme ) and budgie.
Reason why thou shall never user different DE under one user !
And HPLiP tool box, broken.

codic · December 1, 2019, 10:11pm

Lol ok, so you have different users?

Coeur-Noir · December 1, 2019, 10:35pm

Many users. And many systems, currently only 2, ubuntu 16.04 unity in a partition where I do my serious and important things, and UBudgie 18.04 in another partition for testing, tweaking, breaking… 3 users on each system. Therefore dual-boot.

codic · December 1, 2019, 10:35pm

Ah okay. Try the qt5ct fix I mentioned in that case.

Coeur-Noir · December 1, 2019, 11:15pm

And after all that, if I go back in my Unity session in that 18.04 system, all is fine for HPLiP tool so what’s happening here by me ? Why is it correctly displayed only in Unity, and has never been displayed correctly in Budgie, even before I install Unity ???

( I have installed Unity here on 18.04 only to check if HPLiP tool would work there as in 16.04… )

So something in my Budgie sessions might prevent me to use HPLiP tool ?
