Ctrl + Alt + T and Fn keys not working

[Geziel Fernández]

The refered key combinations are no longer working on my desktop. The first one refers to opening the terminal. And the second one should work in combination with F2 or F3 or some other similars for incresing the volumen, or modifying brightness.

PrtScr and Alt-PrtScr are also not working for me. (Alt-F2 does work, though.)

[Geziel Fernández (gezfer)]

Could it be a problem of this version?

LSB Version: core-11.1.0ubuntu2-noarch:printing-11.1.0ubuntu2-noarch:security-11.1.0ubuntu2-noarch
Distributor ID: Ubuntu
Description: Ubuntu Groovy Gorilla (development branch)
Release: 20.10
Codename: groovy

I installed first the Ubuntu 20.04, which was charminly working...
could the 'gorilla groovy' be a mess?

I realized that some additional shortcuts, besides the informed ones, are no longer working. And maybe even worst, not only shortcuts: the brightness adjusting bar, that one in the superior right corner is useless.

[Rocko (rockorequin)]

@Geziel: well, Ubuntu 20.10 *is* a development version, so you expect some bugs. It is normally more usable at this stage of the development cycle, though.

FWIW, I ran evtest, and the keys are mostly being reported the same in groovy and focal - they just don't work in groovy. eg the function keys all report their expected values (eg KEY_VOLUMEDOWN, KEY_VOLUMEUP, KEY_MUTE), with the exception of the brightness up/down keys, which aren't reported in either focal or groovy.

One exception to this is that Alt-PrtScr is reported in groovy as unknown, whereas it's reported in focal as KEY_SYSRQ and KEY_LEFTALT. PrtScr is reported correctly in both as KEY_SYSRQ.

It's still possible to read and change the system brightness in groovy via the kernel, ie on my Dell XPS 15 by catting or echoing an appropriate number to /sys/class/backlight/intel_backlight/brightness, but the function keys don't work and nor does the task bar system menu's dropdown menu slider. The dropdown menu slider is initially set to zero, so it looks like it can't read the brightness, either.

[Sebastien Bacher (seb128)]

The issue is due to the gnome-settings-daemon update, the component got reverted now and blocked in proposed since it shouldn't be updated without the gnome shell new version. You either need to wait for the other component or manually revert to the previous binaries

[Rocko (rockorequin)]

Thanks Sebastien: reverting to gnome-settings-daemon 3.36.1-1ubuntu2 (and rebooting) fixed all the hotkey issues for me.

[Geziel Fernández (gezfer)]

I appreciate your help Sebastien and Rocko... I was a rookie user of
ubuntu, now i'm a less rookie user thanks to you both (not ashamed of being
a rookie, but for reporting kind of a tautological "problem")... I
(re)installed the current 20.04.1 ubuntu version... working charmingly
again... I'm gonna stop being the crazy updater (maybe, but not sure, a
windows heritance)... thank you very much to everyone, again... for me,
this report could be closed, unless is a help for the gorilla groovy.
