As configurações do trackpad da GUI para meu Lenovo 16IAX7 executando o Ubuntu 24.04 6.8.0-48-generic não parecem afetar o comportamento de rolagem. (Nem as configurações do mouse). Estou usando o Gnome DE e o Mutter WM. Li o post aqui, mas isso não parece ser totalmente relevante para o meu caso, pois (por exemplo) não vejo uma opção de rolagem natural. Como eu faria a GUI funcionar ou executaria a rolagem natural de alguma outra forma?
Eu tenho uma configuração de três monitores que estava funcionando em 22.04. Um monitor externo funciona a partir de uma saída HDMI e o outro através de uma saída USB-C DP e um conversor USB-HDMI. Depois de mudar para o kernel 24.04 6.9, o USB-C está bom. O monitor HDMI é reconhecido pela GUI de configurações de vídeo e uma área de trabalho aparece lá, mas o mouse não vai para este monitor e, portanto, é inutilizável, independentemente da configuração do monitor. O mesmo mau comportamento no kernel 6.7.3. Algumas informações do sistema abaixo:

Estou tentando instalar numpy para python3.10 (não em um venv). Eu instalei o python 3.10 usando
sudo apt install python3.10
pip não parecia estar instalado, então eu fiz
jeremy@jeremy-Blade:/$ python3.10 -m pip install numpy
jeremy@jeremy-Blade:/$ wget https://bootstrap.pypa.io/get-pip.py
jeremy@jeremy-Blade:/$ python3.10 get-pip.py
jeremy@jeremy-Blade:/$ python3.10 -m pip --version
pip 21.3.1 from /home/jeremy/.local/lib/python3.10/site-packages/pip (python 3.10)
e depois tentou
jeremy@jeremy-Blade:/$ python3.10 -m pip install numpy
Defaulting to user installation because normal site-packages is not writeable
Requirement already satisfied: numpy in /usr/lib/python3/dist-packages (1.17.4)
Mas quando tento importar numpy:
Python 3.10.0 (default, Oct 4 2021, 22:09:55) [GCC 9.3.0] on linux
Type "help", "copyright", "credits" or "license" for more information.

ImportError:
IMPORTANT: PLEASE READ THIS FOR ADVICE ON HOW TO SOLVE THIS ISSUE!
Importing the numpy c-extensions failed.
- Try uninstalling and reinstalling numpy.
- If you have already done that, then:
1. Check that you expected to use Python3.10 from "/usr/bin/python3.10",
and that you have no directories in your PATH or PYTHONPATH that can
interfere with the Python and numpy version "1.17.4" you're trying to use.
2. If (1) looks fine, you can open a new issue at
https://github.com/numpy/numpy/issues. Please include details on:
- how you installed Python
- how you installed numpy
- your operating system
- whether or not you have multiple versions of Python installed
- if you built from source, your compiler versions and ideally a build log
...
Original error was: No module named 'numpy.core._multiarray_umath'
meu caminho é
jeremy@jeremy-Blade:/$env|grep PATH
LD_LIBRARY_PATH=/usr/local/cuda-10.2/targets/x86_64-linux/lib/stubs
PATH=/home/jeremy/.local/bin:/usr/local/cuda-10.2/bin:/usr/local/cuda-10.2/targets/x86_64-linux/lib/stubs:/usr/local/sbin:/usr/local/bin:/usr/sbin:/usr/bin:/sbin:/bin:/usr/games:/usr/local/games:/snap/bin
(portanto, PYTHONPATH não está definido - se eu o definir como /usr/bin/python3.10, isso não parece mudar nada), e seguindo as recomendações na mensagem de erro, não vejo nenhum problema aqui. (Eu desinstalei e reinstalei o numpy para python3.10, nenhuma alteração vista no problema) Meu sistema operacional é o Ubuntu 20.04. Desculpe se isso é algo óbvio ou não relacionado ao numpy.
Recentemente minha máquina começou a inicializar usando uma tela de login com um lince com olhos de laser (possivelmente uma pantera.)
e o laser-puma não aceita meu login ( failed to start session, não uma msg de senha errada). Eu faço crtl-alt-F3, em seguida, faço login a partir do cli e, em seguida, executo, o startxque me leva a uma área de trabalho kde que é muito boa (o padrão anterior era gnome). Eu gostaria de 1. ser capaz de fazer login desde o início, e 2. ter o kde como desktop padrão (embora eu me importe menos com isso). Eu verifiquei todas as respostas para uma pergunta semelhante (que ocorreu em versões anteriores do ubuntu ), nenhuma das quais parece resolver o problema.
