My problem is similar to this post: https://unix.stackexchange.com/question ... hift-linux HoweveR, I couldn't find a woRking solution yet.

Operating System: KDE neon 5.14
KDE Plasma Version: 5.14.3
Qt Version: 5.11.2
KDE Frameworks Version: 5.52.0
Kernel Version: 4.15.0-39-generic
OS Type: 64-bit
Processors: 4 × Intel® Core™ i7-6600U CPU @ 2.60GHz
Memory: 7.7 GiB of RAM


AfteR a RestaRt, pRessing the "r"-key is not inseRting the "r"-letteR anymoRe.

- PRessing "r" does nothing
- PRessing shift + "r" enteRs "R"
- Holding "r" down does nothing

This is what happens when I pess "r" in

Code: Select all

xev

in konsole:

Code: Select all

FocusOut event, serial 40, synthetic NO, window 0x400001,
    mode NotifyGrab, detail NotifyAncestor

FocusIn event, serial 40, synthetic NO, window 0x400001,
    mode NotifyUngrab, detail NotifyAncestor

KeymapNotify event, serial 40, synthetic NO, window 0x0,
    keys:  2   0   0   8   0   0   0   0   0   0   0   0   0   0   0   0   
           0   0   0   0   0   0   0   0   0   0   0   0   0   0   0   0   

KeyRelease event, serial 40, synthetic NO, window 0x400001,
    root 0x192, subw 0x0, time 1010154, (483,-124), root:(483,778),
    state 0x0, keycode 27 (keysym 0x72, r), same_screen YES,
    XLookupString gives 1 bytes: (72) "r"
    XFilterEvent returns: False

This is what "r" looks like in

Code: Select all

xmodmap -pk

Code: Select all

(R)     0x00b6 (paragraph)      0x00ae (registered)     0x00b6 (paragraph)

I checked whetheR I set a shoRtcut anywheRe but I couldn't find anything. (I also did not knowingly change any shoRtcuts).

The following GIF shows what happens, if I tRy to use onboaRd:

When I log out and login with Ubuntu, I can noRmally use the key "r".

Any ideas to fix this pRoblem?
