If unspecified, it will go to a default file name. This is useful for debugging. Enable: allow browser to use display list for 2d canvas browser makes decision.
You need to close all running instances of Chrome before new flags will take effect since spawning new windows spawns from existing executable. This is valid only in Release mode when --enable-dcheck is specified. If this switch is not used, a simple pressure heuristic based purely on free memory will be used. When Chrome embeds Content, it ignores this switch on its stable and beta channels. See ContentVerifierDelegate::Mode for more explanation. This is only supported on Windows Vista and later.
Set the value to 'always' to always throttle every plugin instance. Kept behind a flag since some drivers lie about supported layouts and hang when used. This will install Chrome for all users. Also we lose the chance to kill some processes until the outer job that owns them finishes. This flag will be removed once the feature gets stable. Touch Exploration Mode will no longer be turned on automatically when spoken feedback is enabled when this flag is set.
This is to be used for testing only. The various modes are always-on, cellular-only, slow connections only and disabled. Should be used only for testing. If a trial name is prefixed with an asterisk, that trial will start activated. Other platforms no longer require it. It is only followed when kRunLayoutTest is set. This only shows an error box because the only way to hide Chrome is by uninstalling it.
This switch may be used to disable that check. I will let you figure out what the F stands for. This does not drop the First Run sentinel and thus doesn't prevent first run from occuring the next time chrome is launched without this flag. Applied after other command line flags and prefs. It should be unset for Chromebooks with both Search and Caps Lock keys e. Shows a dialog asking the user to try chrome. Next part is the script that I use to start close and restart chrome again in kiosk mode.
Pseudo traces are derived from currently active trace events. This does not start service or register proxy for autostart. The pages that open on startup are controlled by the RestoreOnStartup policies. This is needed for tests since they use a custom-user-data-dir which disables this. I just tried it with the following command chrome. It should not be enabled for most Cast devices.
Disabling this switch also disables the use of persistent gpu memory buffers. Please change both locations at the same time. Even registry editing gets overwritten when I log off ;.
