saulodebaco last edited by@burnout426 Many tks, friend. The option --lang=pt-BR worked like a charm! To make it easier I have added this to file /usr/share/applications/opera.desktop/ 
 Exec=opera --lang=pt-BR %U

scitari last edited byHeja, The Opera browser I have running under Linux (Linuxfs, Ubuntu-based), is missing the option to change browser/interface language. The option I have with Opera under Windows 10 (= selecting browser language in "preferred languages" within settings) seems to be missing. Google Search didn't really reveal promising answers. What do I need to do to change Opera language? Best regards

scitari last edited by@leocg Yes, thanks, did, I understand the workaround, but in my case Opera is set-up in a snap, and editing files as root in a read-only environment is actually not really user-friendly. Having the same browser setting in the Linux version as in the Windows version would likely help adoption by other users. Just a gentle nudge to Opera developers. Best

reinaldofox last edited by leocgOpera cares so much about filling the app with nasty and unnecessary things and doesn't pay attention to such a basic and crucial thing.

Saragoo last edited byOK, there is something that may work. I opened my filemanager (Nemo or Thunar or ...) with the terminal (sudo nemo) and then i go to /usr/share/applications 
 Right-click on Opera and open the attributes menu (in German "Eigenschaften", i do not know if the translation is correct).
 Change the command opera %U into opera --lang=de (de for german, choose your language)
 Close this. Now Opera should open in the correct language. I hope it works.

Saragoo last edited byTried to post a solution here, but Opera Forums doesn't want to publish it. Only thing Opera cares is to place promotion into the Browser.

philou-69210 last edited by@saragoo Hello, this workaround was already post here. Developers of Opera don't take care of their Linux Users. It's a shame.

kocis2023 last edited by@philou-69210 In Artix with openrc, it was enough to click PM on the Opera icon on the desktop and in the attributes of this icon, complete the following command: exec=opera --lang=pl %U. 
 And it works. It turned out that there was no need to enter the system.

philou-69210 last edited by@kocis2023 Hi Kocis, it was enough for me to edit the application file each time Opera release an update. I imported my bookmarks in Firefox and uninstalled Opera from all my devices.

trsword52 last edited byCreate create folders, select edit launcher to provide desktop. 
 Type opera %U --lang=(your lang) in the command line and save it.
 With this shortcut you have created on your desktop, the transponders are opened in Opera Your Lang
 Example:
 Type opera %U --lang=tr

bilalerdiyildiz last edited byHello, 
 I use Fedora 38 Workspace (Gnome). I have tried all the solutions here, but there is no solution. Opera One is still in default language. Is there any other method other than these that I should do?

tobiasitalo last edited by leocg[Hello, 
 Neither in the stable version nor in the dev version am I successful in carrying out the procedures I found on the internet (and those in this forum as well).][For example, access the settings and set Portuguese as the preferred language.]   [My Operating System is in Portuguese natively. Below are the versions I'm currently using of the OS and Opera (with all updates available to date):]

smitharro last edited by@the-codifier said in Can't change UI language. No option "Display opera in that language": I had the same issue when I recently installed Opera Stable on Fedora 36 KDE. My native language is spanish, so I will use this language on this tutorial. Probably it will work for all Linux distros. - Go to this route on your File Manager /usr/share/applications
- In this route, you find many files with .desktop extension. These are the icons you use to open the programs. Find the Opera Browser one (usually called opera.desktop)
- Right click on it and open with your favorite text editor (I use Kate in KDE)
- The first section must look like these
 [Desktop Entry] Version=1.0 Name=Opera GenericName=Web browser Comment=Fast and secure web browser TryExec=opera Exec=opera %U Terminal=false Icon=operaLocate the line Exec 
 5. Add the text lang=your language after the word opera. Example for spanishExec=opera --lang=es %U- Write the --lang flag in all places where you find Exec on the file
- Save the changes on file. Probably the text editor claim you for the super user (root) password. Type it.
- Double click on Opera icon. Your browser now opens on the language you selected.
 The reason of this is: Opera is charged with all the languages, but the instruction that launches must be declared with the flag --lang to be opened on the language you want. I hope I have been helpful. Thanks, though the topic is old, in my case it was helpfull and it worked!
