|
|
|
Watch for dconf changes by opening a terminal and running dconf watch / |
|
Set a temporary custom GNOME shortcut (Settings -> Keyboard -> View and Customize Shortcuts -> Custom Shortcuts) |
|
The dconf command will display the chosen shortcut keys. Delete the shortcut and use the displayed shortcut in the above customization commands. |

=== GNOME (ubuntu) 20 - Problems on Dell |
|
|
|
* WiFi + blutooth |
|
** https://overflow.roche.com/t/i-cannot-connect-to-wifi-on-my-dell-xps-9310-what-should-i-do/6739/7 |
|
*** git clone git://git.kernel.org/pub/scm/linux/kernel/git/firmware/linux-firmware.git |
|
*** sudo cp -r linux-firmware/ath11k /lib/firmware/ |
|
|
|
===== External Display is not visible |
|
|
|
* gnome does not see external display |
|
* trying to fix it |
|
** sudo apt-get install kubuntu-desktop |
|
** it didn't help |
|
*** on my home computer I have KDE as a windows and external screen works with HP computer (also Ubuntu 20th) |
|
|
|
* idea to check |
|
** in the office with the external screen |
|
|
|
===== No visible Blutooth |
|
|
|
* at least in gnome |
|
** and little ports to use |
|
|
|
|
|
==== gnome-shell |
|
|
|
* gnome-shell --version |
|
* install extension manually from zip |
|
** e.g. wintile |
|
*** przykład na innym extension: |
|
**** https://linuxconfig.org/install-gnome-shell-extensions-from-zip-file-using-command-line-on-ubuntu-20-04-linux |
|
*** unzip -C wintilenowsci.com.v7.shell-extension.zip metadata.json | grep uuid | cut -d \" -f4 wintile@nowsci.com |
|
*** mkdir -p ~/.local/share/gnome-shell/extensions/wintile@nowsci.com |
|
*** unzip -q wintilenowsci.com.v7.shell-extension.zip -d ~/.local/share/gnome-shell/extensions/wintile@nowsci.com |
|
*** gnome-extensions enable wintile@nowsci.com |
|
*** In order for the changes to take effect, you’ll need to restart the GNOME shell. The quickest way of doing so is: |
|
**** to press Alt+F2 on your keyboard, type r, and then press enter. |

===== Paint pod Gnome |
|
|
|
* pod gnome za maleńkie ikonki (i nie dało się tego poprawić) |
|
** Pinta |
|
** xpaint |
|
** KolourPaint |
|
* pod gnome działały (ikony do rozczytania) ale trudne i skomplikowane programy: |
|
** Krita |
|
** MyPaint |
|
* rozwiązanie |
|
** kUbuntu Plasma <=> KDE - KolourPaint ma normalne ikony |
|
|
|
=== KDE - Ubuntu 20 |
|
|
|
* nie działał ekran startowy - doinstalowywałam |
|
* języki - tutaj uwaga: |

*** Language - MUSI zostać angielski inaczej CAŁY SYSTEM linux będzie po polsku |
|
*** Formats |
|
**** Region: Polska - ustawienia w KDE i komunikaty systemowe są po polsku |
|
**** Region: MUSI zostać angielski inaczej CAŁY SYSTEM linux będzie po polsku |
|
**** Detailded Settings: Jednakże ustawienia szczegółowe można przestawić na "Polska", nie wpływają na język systemu |

** Global Shortcuts |
|
* dodanie sztywnych wirtualnych desktopów |

|
** etc/vim/gvimrc |
|
*** colorscheme desert |
|
*** colorscheme slate |
|
*** colorscheme torte |
|
** these settings seems to be not necessary under Linux |
|
*** set langmenu=en_US |
|
*** set nocompatible |
|
*** set nu |
|
*** set guifont=Monospace:h13 |
|
* Zegar na pasku |
|
** Event Calendar widget - skonfigurowany pode mnie |
|
** wygląda dobrze tylko jeśli taskbar jest u dołu |
|
* Restore previous session - jest domyślny w KDE |
|
* System Settings -> Screen Edges |
|
** aka hot corners |
|
** podłączanie różnych przydatnych zachowań pod "gorące punkty" |
|
** można też dodać dzielenie ekranu na 4 ale to działa nie dla "ekranu" ale dla całego workspace |
|
* podział ekranu na 4 w rogach |
|
** Global Shortcuts -> kWin użycie i podpięcie pod akcje skrótów (te się sprawdzają i są intuicyjne - z Windows???) |
|
*** Quick Tile Window to the Bottom Left : Meta+Ctrl+Left |
|
*** Quick Tile Window to the Bottom Right : Meta+Ctrl+Down |
|
*** Quick Tile Window to the Top Left : Meta+Ctrl+Up |
|
*** Quick Tile Window to the Top Right : Meta+Ctrl+Right |

@alan-hwp are you using Ubuntu's custom distribution of Maven? The official Maven distribution uses the "no-AOP" build of Guice which doesn't contain any CGLIB code. If you download an official distribution from https://maven.apache.org/ then you shouldn't see the warning. |

=== Profiles |
|
|
|
==== Create env variables |
|
|
|
---- |
|
# Global env variables |
|
/etc/profile |
|
/etc/profile.d -> put your own file |
|
|
|
# Local env variables |
|
/home/.../.profile -> or .bash_profile or .bash_login |
|
---- |
|
|
|
https://www.baeldung.com/linux/environment-variables[Env variables] |
|
|
|
With Bash, we declare global variables in /etc/profile. But, we recommend declaring them in their own script files and putting those in /etc/profile.d. Bash will automatically pick these up. |
|
|
|
Global variables affect all users in the system. Each user can create a set of “global” environment variables for their own by creating ~/.profile in their home directory. |
|
|
|
==== Load profile |
|
|
|
source .profile |

== System |

=== Log location |
