Answers to Frequently Asked Questions (FAQ) regarding "Opera for Linux"

Welcome to the Opera for Linux Browser FAQ. If you are using Linux and are looking for a cool browser, check out Opera's web site and Download Opera 7.11 Final for Linux, FreeBSD or PowerPC. They claim Opera to be the fastest browser on earth! Well, they might actually be right. :)

On this page, you'll find answers to frequently asked questions (FAQs) concerning the Opera browser. Some answers and tips apply only to Opera for Linux while others apply to all or most Opera versions.

Opera Linux auf Deutsch

Für die Linux-Version von Opera 6.1x gibt es auch ein deutsches Sprachmodul:

Die Sprachdatei und Hilfe ist speziell für Linux angepasst und erweitert worden und auf inhaltliche Korrektheit geprüft. Auf jeden Fall sofort die deutsche Hilfe und Sprachdatei installieren!

Für die Linux-Version von Opera 7.1 gibt es noch keine deutsche Sprachdatei. Oliver J. Thiele bietet aber zumindest eine deutsche Sprachdatei und Hilfe für die Windows-Version von Opera 7 an, die mit Opera 7.11 for Linux funktioniert. Allerdings konnte noch nicht alles übersetzt werden.

Opera for Linux Knowledge Base Articles

I compiled a list of Opera for Linux Knowledge Base Articles. Check if one covers your topic.

Don't try to get Flash or Java to work in Opera 5.0

If you are having problems installing the Flash or Java plugin in Opera 5.0, forget about it. For Java and Netscape plugin support in Opera for Linux, you need Opera 5.05 or newer. The Opera 6.0 for Linux browser is really great. So install the latest Final (unless you have a registered version of Opera 5.0 and don't want to upgrade even though it's free).

Read Opera's Plug-In Documentation for Opera for Linux for information about the following plug-ins: Adobe Acrobat Reader, Macromedia Flash, Plugger, Sun Java 2 Runtime Environment with Java Plug-in 1.3.1.

Opera hangs if site uses Flash

If Opera freezes when you access a Flash page, try starting Opera like this:

For Gnome, try this from command line (terminal): esddsp opera

Or, for KDE: artsdsp opera

Don't lose your menu bar ;-)

Since "I lost my menu bar, how do I get it back?" is a FAQ in the Opera for Linux forum, here two answers: Either close all windows and right click on the empty workspace and select Show menu bar or simply press Ctrl+F11.

Change the threshold of the "Open page" warning

Opera can warn you, before it opens a lot of bookmarks at once. It will then display a message box and ask you something like "You are about to open 903 pages. Proceed?". The default threshold for this warning is four. So if you open more than four pages, Opera will ask you before it proceeds. You can change this threshold or disable it by editing ~/.opera/opera6.ini. Make sure to close Opera before editing the file. Then use

[HotListWindow]
OpenWarningLevel=n

Set n to either the new threshold, e. g., 10, or to -1 to disable it. Note: The [HotListWindow] entry will probably already exist. So look for it first.

Update: Make sure to read the following Opera for Linux Knowledge Base article: Hidden .ini settings in Opera 6 for Linux.

Hotlist panels (sidebars) in Opera 6

Check out Rijk van Geijtenbeek's Hotlist panels in Opera overview.

Hotlist Panels (Registerkarten, Karteikarten) in deutscher Sprache

Roland Reck bietet eine Überlick über verschiedene Hotlist Panels (Karteikarten bzw. Registerkarten) für Opera.

Use keyboard shortcuts

Press Ctrl+B to access Opera's keyboard shortcuts. Print them. Read them. Learn them by heart. And don't forget to use them. :)

Use Mouse Gestures

You don't like keyboard shortcuts? Use mouse gestures instead! On your menu bar, select Help | Mouse and read all about it.

Buy multiplatform licenses

Consider buying an Opera license for Windows or Linux? Instead, buy multiplatform licenses for both platforms and save more than 30 %.

For each full license for a platform, you are entitled to a discount when purchasing for other platforms. So if you have purchased Opera for Windows, you will get Opera for Linux for USD 15.

Right now, I am trying to figure out if it is possible to cross-upgrade for free from Opera 5 for Windows to Opera 6.0 Linux. You can definitely upgrade from 5.0 to 6.0 for free. But I am not sure if this also works across platforms, i. e., if cross-upgrades are free. Anyone?

Don't use a foreground skin image

Whatever you do, don't use a foreground skin image! It will take up 20 MB! Nothing I can think of can justify this. So make sure "Preferences | General | Look | Skin images | Foreground skin image" displays "No skinning".

Update: There were lots of improvements regarding skins in later version of Opera, so this is no longer true with Opera 6.12.

Use WWWoffle, Privoxy or other proxies

Use a proxy. Actually, use at least two! ;-) I am using WWWOfflE and Privoxy. WWWOfflE lets you browse offline and select links for download. It will fetch them the next time you go online. Privoxy will block all unwanted content, for example, banners, ads and pop-ups. Privoxy is really easy to install and configure.

Customize your search.ini

If you don't like Opera's default search engines, change them! I put this on a separate page called "How to change Opera's default search engines using search.ini".

Underline acronyms and abbreviations

You might have noticed that some acronyms and abbreviations on this page are underlined with a thin dotted line. To make Opera underline acronyms and abbreviations that have been defined by the web designer, you can put the following line in your private style sheet and select it in "File | Preferences | Document | Page style | My style sheet". Make sure to check "My style sheet" in the "Author mode" frame.

abbr, acronym { border-bottom : 1px dotted #333333 ; }

Use antialiased fonts (Qt dynamically linked)

Are you using Qt statically or dynamically linked into Opera for Linux? In the latter case, add the following two QT_XFT entries at the end of your Opera startup script (usually found at /usr/bin/opera/):

QT_XFT=1

# Exporting the environment
export OPERA_DIR OPERA_PLUGIN_PATH PATH QT_XFT

In order to get anti aliased fonts you need X with libfreetype. In addition you need a Qt which has been compiled with xft.

Update: There were some changes regarding anti aliased fonts in Opera 6.1. I'll update this section as soon as I've figured it out. ;-) There's now also an option Apply smoothing to core X-fonts in "File | Preferences | Document | My fonts and colors".

Use a TrueType font server (Qt statically linked)

In case you are using a Qt statically linked Opera build, you should download some free TrueType core fonts for the Web from Sourceforge (or use the *ttf files from your Windows partition) and use a truetype server, e. g., xfstt. xfstt is part of SuSE Linux 7.1 and pretty easy to install. Read /usr/share/doc/packages/xfstt/README.SuSE.

For more information read the TTF Mini-FAQ and this Font HOWTO.

Activate font dump mode

Sometimes you will notice that Opera displays some characters above the base line or characters from a different font family. If you want to know what character Opera is using, activate the font dump mode.

  1. Open a terminal (kterm, xterm)
  2. Start Opera (opera)
  3. Make sure zoom is set to 100 %
  4. Press Ctrl+RightClick twice to enter or leave the Font dump mode

Every time you click (single LeftClick) on a character, Opera will print some information to the start-up terminal, e. g., when clicking on the EUR character on some web pages, you might get something like this:

== Font information ==
Font (88): "misc-fixed-15"
Content: 20ac

This means Opera is using the misc-fixed font. The final -15 means iso8859-15. This holds for the numbers 2-15, while iso8859-1 is -0, and unicode is -22.

Content: 20ac (or Point: 20ac) means that the selected character was Unicode character 20ac, which happens to be the euro character. Now, if Opera had displayed something else instead of the EUR symbol, it would have implied that the font has the wrong character in that position (happened when I had lucidux installed on my system).
