Chromium

Chromium is Article description::the open source version of Google's [[Chrome web browser.]] It features a minimal user interface, powerful web development tools, and a built in task manager. The Chromium Project is at the forefront of implementing new web standards.

Because Chromium is open source it is legally unable to include several features that the proprietary Google Chrome browser includes by default. Namely automatic updates. A complete list of the differences can be found in the chromium repository.

l10n (Linguas)
There are many linguas available via USE_EXPAND in Chromium. So many, in fact, that the wiki cannot display all of them. For a full list of linguas run:

Emerge
After setting USE flags as desired, Chromium with the following command:

HiDPI
Chromium's visual output is generally disconnected from a Desktop environment's DPI scaling. It can be instructed to start in a scaled mode by using the  command-line option. This option can be passed a integer or decimal value. Standard scaling begins at 1.0. For example, to make Chromium's UI 1.5x larger:

A full list of command-line switches can be found here.

Native Wayland support
Since version 87, native Wayland support in Chromium can be enabled by passing the following options:

To set Chromium to start every time using the Wayland backend, append the following lines the user's Chromium configuration file:

Disable Tab Hover Cards
Since version 91.0.4472.77 it is no longer possible to disable the Tab Hover Cards within Chrome flags. There seems to be no priority at Google to add this feature back in. In order to disable them, you can add this patch to Portage:

Chrome URLs
Much like Firefox, Chromium has many internal Chrome URLs (special pages) that are used for additional configuration, troubleshooting, task management, etc. An exhaustive list of special pages can be accessed by navigating to:

Prominent special pages include:


 * - Shows enabled components and provides a button to check for updates for each of them. It is sometimes necessary to manually update the PPAPI Adobe flash module via this interfaces when using Chrome.
 * - Displays the About page which includes version information.
 * - A page to manage extensions.
 * - Enable/disable experimental features.
 * - Displays special information about the Adobe Flash Player (if it is accessible by Chromium).
 * - Displays information about use of graphics acceleration.
 * - Displays web history. Also accessible through the sandwich menu or by pressing +.
 * - Measure the memory usage of the browser and per-tab usage.
 * - Lots of information on network connections.
 * - Shows a list of plugins. Enable/disable them from this interface. (Deprecated in Chrome version 57 .)
 * - Displays more version information than the  page.

Tabs crash
Occasionally tabs in Chromium crash. This can be caused by quite a few things, however one of the most common reason for occurrence is that the system is running low on memory. On Gentoo, this can especially happen if the system is compiling a package update while running Chromium.

The command can be used to see how much memory is available on the system:

The solution to is to free up memory until the large package compiles have finished. Open a resource monitor of choice and kill applications using large amounts of memory.
