Page up/Page Down has no effect - Ubuntu 22 about beamerpresenter

[stiglers-eponym]

I could not reproduce this in a virtual machine with Kubuntu 22.04. Maybe you could check whether you have a broken config file:

• Run beamerpresenter with the option --config none to use only the hard-coded default configuration.
• Expected behavior: Page Up and Page Down should work, Home and End should not work.
• If you see a different behavior: Please attach you config file (usually in ~/.config/beamerpresenter/beamerpresenter.config)

--config=none has no effect. The config file follows.
Thank you.

--config=none has no effect, so even Home and End keys still work? That's strange.
I'll try to reproduce it using an Ubuntu VM.

[shashi-prabh]

No. With --config=none, Home and End keys also don't work.

In a newly installed ubuntu 22.04 in a VM I cannot reproduce this issue. For both QT_QPA_PLATFORM=xcb or wayland the page up and page down keys work in beamerpresenter-poppler-qt5-jammy-x86_64.deb.

You could try to give me further information about your system to reproduce this issue, or you could try to run in debug mode to provide more information: When you build from source, you can use the cmake option -DCMAKE_BUILD_TYPE=Debug to enable debugging. Then you can run beamerpresenter with --debug=key-input to see which keys are recognized by the program.

[stiglers-eponym]

Just to make sure that I understand you correctly: On your system the page up and page down keys have abolutely no effect in beamerpresenter?

[shashi-prabh]

Yes

OK. Will do.

[shashi-prabh]

Remapping the keys in the config file solves the issue.

U=next
D=previous

OK for now.

[stiglers-eponym]

OK, but still, this is a strange issue. If you find out what caused the problem or if you find any better debug output, please let me know.

[shashi-prabh]

The issue was with the laptop -- a Dell Inspiron one. On its keyboard Page UP/Down keys are activated only with Fn key pressed. Very poor judgement by Dell engineers. Never came across this before.

It might be better if you map slide changes to the Left and Right keys also in the default config file:

Right=next
Left=previous
PgDown=next
PgUp=previous

Thank you for your help.
