I just compiled pdfpc 4.5 on Ubuntu 24.04. Everything works as expected. This confirms that the problem was probably introduced with pdfpc 4.6. |
So what does happen, exactly? Do you mean the pointer becomes the default cursor in its function and appearance? Do you observe the same problem in the eraser mode? |
|
Actually, for some reason I do not understand, now I observe a slightly different behavior:
In any case, after this happens, the tablet does not react anymore until I restart pdfpc. But now I suddenly also observe this behavior with pdfpc 4.5, so I am not sure any more whether the reason for the problem is not more complex than I originally thought. I also tried with xournal once more, and there everything works o.k. Is there anything I can do for debugging? |
It's the intended behavior.
What if you reset the pointer mode manually ( Also, please try enabling |
|
I understand that the pointer vanishing is the intended behavior, but why should it not come back if I use the pen again? This disables using the pen on one slide, putting it aside, continuing with the presentation and using the pen once more, later. Resetting the pointer mode manually (1) does not help. I already set disable-input-autodetection to true in pdfpc Is there no verbose mode that shows which events pdfpc recognizes and how it reacts to them? This would help debugging... |
Of course, it should. Why it doesn't work for you (or even more specifically, doesn't work with this specific device) is the question.
Doesn't help to do what? Do you see a pointer at all? If you move the mouse?
Weird. If the autodetection is disabled, the tablet input should essentially work like a mouse.
No, but you can use the usual debugging or add some printf calls in |

P.S. I suggest you compare the events that your two tablets generate and see where the difference comes from, using the |

I have some new insight:
Does this help in any way? |

What is your monitor configuration? I.e., single or dual? Try running pdfpc with a single presenter window ( |
|
Dual (which, for me, is the main point of using pdfpc). |
|
|
pdfpc -S does not make a difference:

|
Which window manager/desktop environment do you use? The standard one that comes with Ubuntu-24.04? |

yes, the standard one that comes with Ubuntu-24.04 |
Uh oh!

I am using a One by Wacom S tablet on Ubuntu 24.04. Both for pdfpc 4.6 from the Ubuntu package pdf-presenter-console and freshly compiled pdfpc 4.7, when lifting the physical pen away from the tablet the pdfpc pen vanishes (which is expected), but does not come back when moving the physical pen back.
When using other applications (e.g., xournal), the tablet works as expected. Everything also worked as expected in Ubuntu 22.04 (pdfpc 4.5). When using a different tablet (Wacom Intuos4) in the current setup, pdfpc also works as expected. So the only problematic combination seems to be One by Wacom S together with pdfpc >=4.6.
