 Posted: Wed May 08, 2024 10:22 am Post subject: KDE plasma freeze after typing specific special characters |
 |
|
Hello everybody,
I am experiencing freezes on KDE Plasma after typing special characters specific from Spanish language: ª, ° and ¿ (to get those, I had to use "insert special character" in Libreoffice, and then copy-paste it here...). I have no problems with others like %, &, € , Ç, ñ, or with dead keys for accents, like á, è. î. In fact those three (ª, ° and ¿) are the only ones I have this problem with.
In a terminal, I have no problems in typing those special characters. It only occurs when I am into KDE Plasma, in any program or application, like Konsole, Firefox or Libreoffice. After the freeze, I can still use Ctrl+Alt+F2 to go to a terminal and kill X, and everything goes back to normal after restarting X - KDE with startx. So it looks like just a screen freeze, but I am not sure if anything else is working.
I have been having this issue for a couple of months now, as I could not identify the problem, and thought they were just random freezes. Those keys are seldomly used, but they are next to the ESC and DEL keys in the keyboard, so it is easy to accidentally press them from time to time and without noticing it. It has been when I was writing an email in Spanish with a few questions that I noticed the cause, and then tested the rest of special characters. I believe it started to happen after some update, but I cannot say precisely when and what update was the responsible.
I have tried to change the locale from en_US.utf8 to es_ES.utf8 and back, to no avail. The computer language is English, but I still have the keyboard layout to Spanish to be able to use dead keys and those special characters.
I am using kernel 6.6.21, KDE Plasma 5.27.11. I also have a NVIDIA RTX 4060 GPU using nvidia-drivers 550.76, if that is of any use.
Thank you very much in advance for your help. |

Hello,
That is indeed very weird.
I use bépo as a keyboard layout, and it allow access to some «uncommon» keys such as:
And way more, without having any kind of freeze in KDE Plasma or Xfce currently.
I'm maybe just guessing, but it looks like a bug (from KDE, Gentoo ?!).
----
Before digging more:
1/ What is your graphical server in use: X.org, Wayland ?
- a) Have you tested with both ? If both are installed, you can easily switch from SDDM menu (top-left corner IIRC)
2/ What is your GPU ?
You already answered that actually: NVIDIA RTX 4060 GPU
3/ What drivers is in use and configured into make.conf ?
| Code: | | grep -rin "VIDEO_CARDS" |
Same as point 3: nvidia-drivers 550.76
4/ How do you start you KDE Plasma session ? From SDDM ? StartX ? Other ?
5/ Could you try to reproduce this behaviour with another key mapping ? Did it still occur ?
6/ I do not know if it would be relevant, but in any case:
It could maybe give us some clue.
Since you are also using the NVidia-drivers, maybe it is worth to try nouveau, just in case it leads us to a problem from the drivers, or not. I guess it's not because of it, would more assume it's about X.org/Wayland. But still.
Hope to find you a fix for that, after months you are probably kind of annoyed ! :)
Regards,
GASPARD DE RENEFORT Kévin

Currently is X11. I have just switched to Wayland, and the issue dissapears!

Code:
lspci | grep VGA

Yes, but I also have an Intel:
| Code: | # lspci | grep VGA
0000:00:02.0 VGA compatible controller: Intel Corporation Alder Lake-P GT2 [Iris Xe Graphics] (rev 0c)
0000:01:00.0 VGA compatible controller: NVIDIA Corporation AD107M [GeForce RTX 4060 Max-Q / Mobile] (rev a1)

grep -rin "VIDEO_CARDS"

| Code: | # grep -rin "VIDEO_CARDS" make.conf
20:VIDEO_CARDS="intel nvidia" |
| Quote: | | 4/ How do you start you KDE Plasma session ? From SDDM ? StartX ? Other ? |
startx
| Code: | # cat .xinitrc
xrandr --setprovideroutputsource modesetting NVIDIA-0
xrandr --auto
exec dbus-launch --exit-with-session startplasma-x11
|
| Quote: | | 5/ Could you try to reproduce this behaviour with another key mapping ? Did it still occur ? |
Yes, I tried with american english standard keyboard, and I get the same behaviour.
| Quote: | 6/ I do not know if it would be relevant, but in any case:
Code:
emerge --info |

So it looks like a problem in X, as Wayland does not have the issue. What can I test/change? (appart from moving to wayland)
Thank you so much for the fast answer! |

Viloflo,
I don't have a problem typing the ¿, º and ª characters in applications (Yakuake, Konsole, KWrite, Kate, Firefox, LibreOffice, etc.) running in KDE Plasma under X11. My main laptop has Gentoo Linux (amd64) running OpenRC with NVIDIA Optimus graphics hardware, and it uses both nvidia-drivers and modesetting driver (xf86-video-intel is not installed):
| Code: | $ grep VIDEO /etc/portage/make.conf
VIDEO_CARDS="intel modesetting nvidia" |
| Code: | $ eix -I nvidia-drivers
[I] x11-drivers/nvidia-drivers
Available versions: [M]390.157(0/390) 470.239.06(0/470) 525.147.05(0/525) 535.161.07(0/535) 535.171.04(0/535) [M]~550.40.59(0/vulkan) 550.67(0/550) ~550.76(0/550) {+X dist-kernel kernel-open +modules modules-compress modules-sign persistenced powerd +static-libs +strip +tools wayland ABI_X86="32 64"}

Thank you Fitzcarraldo! I will play around with the keyboard configuration in X and see if I get some results.
