The Chromebook Central Help Forum is an active, searchable community for user discussion of bugs and feature requests. It‘s a great place to ask for help, and there’s a good chance that your question has already been asked (and answered, hopefully).
Feedback reports are the primary mechanism by which Chrome OS users can send feedback about the project. Reports are clustered into categories that are used to identify larger issues, but they are typically not individually reviewed. Submitted reports are not publicly accessible.
To submit a feedback report, type Alt+Shift+i or click
Report an issue... within the
Help submenu while logged in. Feedback reports include selected system logs if the
Send system and app information, and metrics checkbox is checked. You can click the links within the checkbox text to see the information that will be attached to the report. See the official feedback documentation for more information.
The Chromium project‘s public issue tracker is used by developers to track Chrome OS bugs and feature requests. New issues submitted here are periodically triaged to receive component labels, at which point they should be examined by component owners. If you’re a Chromium project member, you can assign components and other labels yourself to expedite this process.
Issues are publicly-viewable by default, but the
Restrict-View-Google label restricts the issue to Google employees. go/newcrosbug (internal link) may be used to start a new issue with this label.
It‘s also possible to collect extensive system logs rather than the subset that’s included in feedback reports. To do this, enter
chrome://net-internals/#chromeos in the location bar and click the
Store Debug Logs button. The resulting
debug-logs archive file will be placed in your Downloads folder. It may contain personally identifiable information, so you may want to either:
Screenshots are extremely helpful when debugging UI-related issues. To capture a screenshot on a Chrome OS device, hold Ctrl and hit the Switch Window (a.k.a.
[ ]]]) key (or F5 if you‘re using a non-Chrome-OS keyboard). The screenshot will be written to your Downloads folder if you’re logged in or to
/tmp (which can be accessed by browsing to
file:///tmp after logging in) if captured at the login screen. To take a screenshot of a limited region of the screen, use Ctrl+Shift+Switch Window and drag a rectangle using the touchpad.
When the Chrome process, some other system process, or the Linux kernel crashes, a crash report will be generated and sent if the
Automatically send diagnostic and usage data to Google setting is enabled. When this happens, you should later be able to see information about the report at
If you give the ID to a Chrome OS developer, they can look up more details about the report that will hopefully help them determine the crash's cause.
If the entire UI (including the cursor) freezes or hangs, it can indicate various problems, including:
If you see a freeze, try pressing Alt+Volume Up+X once, with the keys depressed in that order. (If you're using a non-Chrome-OS keyboard, use Alt+F10+X instead.) This will instruct the Linux kernel to attempt to make the Chrome process crash and restart.
If that doesn't help, try pressing the three-key-combination two more times. This should trigger a kernel panic, resulting in the system rebooting.
If the system is still frozen, you've probably encountered a lower-level issue. Holding the power button for eight seconds should force a reboot.
If you were able to trigger a Chrome crash or kernel panic, you may be able to find the crash ID at
chrome://crashes after logging in again. Full debug logs may also contain more information about what went wrong.
If you think you've identified a bug in Chrome OS, please do the following:
Send system and app information, and metricscheckbox is checked before sending the report. Sending system information allows developers to view logs; this is almost always necessary in order to investigate bug reports. (If an issue is already tracking the bug, please include its ID in the feedback report’s description and add a comment to the issue mentioning that you've submitted feedback).
