How can I get chromium-browser to run fullscreen (not kiosk) in 12.04?

I have created a restricted user which logs in automatically and Chromium runs the default home page with the screen starting maximized but I want it to run in fullscreen (F11) mode. I tried kiosk mode but I don't want to be that restricted and it doesn't seem to behave properly at all (keyboard is almost broken).

I would consider digital signage software but don't really want anything client/server. I just want the machine to boot straight into fullscreen mode. Does this work for firefox?

For people finding this now, you can start Chromium fullscreen from the command line by executing:

chromium-browser --app= --start-fullscreen

Tested on Ubuntu 14.04 LTS

What about using xdtool

xdotool key F11

this will work for any kind of standard focused window. Include it into start-up script.

don't have xdotool?

sudo apt-get install xdotool

in combination with --start-maximized (which does not do F11, just maximized window) on command line can fulfil your needs

shell script should make the job

chromium-browser --start-maximized
sleep 5
xdotool key F11

Firefox differs only in -fullscreen command line option. The option for F11 mode is missing as well. But consider to use Firefox and Rkiosk extension or the Fullscreen extension

If the script stucks at chromium-browser invocation - add a & at the end:

chromium-browser --start-maximized &
...

Based on this and other sources, you could try the following, with good chances of success :-)

cp /usr/share/applications/chromium-browser.desktop ~/.local/share/applications/chromium-browser.desktop
nano ~/.local/share/applications/chromium-browser.desktop 

(you may alternatively want to use gksu and the editor of your choosing)

Now, simply add -start-maximized to the line saying exec in chromium-browser.desktop, save and you're done.
