Alt-Taste wird nicht erkannt bei KDE Plasma auf FreeBSD 15

[felditux23]

Hallo zusammen,

ich habe in FreeBSD erfolgreich KDE Plasma installiert. Der Desktop ansich funktioniert soweit auch. Allerdings habe ich den seltsamen Bug, dass die Alt-Taste komplett ignoriert wird. Zum Beispiel zeigen Alt-Tab und Alt-F4 keinerlei Funktion. Andere Desktop-Umgebungen und Window-Manager sind nicht betroffen und funktionieren dahingehend einnwandfrei, getestet habe ich das zum Beispiel mit mate.

xev reagiert sofort auf die Tastendrücke von Alt und auch auf Tastenkombinationen wie Alt-Tab:

Dass es an der verwendeten Hardware liegt, kann ich eigentlich ausschließen, da es sowohl in einer Virtualbox-VM (mit installierten Guest Additions) als auch auf nativer Hardware passiert. Kann mir jemand beim Troubleshooting helfen? Irgendeine Kleinigkeit werde ich wahrscheinlich übersehen..

Hier ist beispielhaft die rc.conf von einer VirtualBox-VM, wo das passiert:

Spoiler

hostname="feldibsdvm"
keymap="de.kbd"
ifconfig_em0="DHCP"
ifconfig_em0_ipv6="inet6 accept_rtadv"
sshd_enable="YES"
ntpd_enable="YES"
ntpd_sync_on_start="YES"
moused_enable="YES"
dumpdev="AUTO"
zfs_enable="YES"
vboxguest_enable="YES"
vboxservice_enable="YES"
dbus_enable="YES"
sddm_enable="YES"
kld_list="linux linux64 vboxvfs"

Ansonsten sind die Konfigurationenn bei dieser VM hier alle noch Standard, keine custom Xorg.conf oder ähnliches. Wenn ihr noch irgendwelche spezifischen Logs oder Configs benötigt, sagt einfach Bescheid.

Danke schonmal für die Hilfe!


Schöne Grüße

Die Tastenkombinationen von KDE unter FreeBSD sind irgendwie schon länger kaputt. Alt+Tab und Alt+F4 z.B. sind nicht belegt. Du kannst das über das KDE Kontrollzentrum aber ändern und neu setzen.

Oh wow, das war es tatsächlich, ich hatte eher etwas systemnäheres wie Xorg im Verdacht. Danke für die schnelle Hilfe!
