I need to open browser on a certain page each time the laptop wakes up from hibernate / sleep and on boot.
I've created a script wakeUp.sh in folder
chmod 777 /lib/systemd/system-sleep/wakeUp.sh to give all rights to the file for sure.
Now the script it self (where I try to make the browser open on page after I close-open the laptop lid [sleep-wakeup]):
#!/bin/sh echo "$@" > /tmp/wakeUpParams.txt case $1/$2 in post|*) chromium-browser --no-sandbox http://google.com 1>/home/liza/out.txt 2>/home/liza/err.txt echo "$@" > /tmp/AfterBrowserLaunch.txt ;; esac
In the script, I save the output of the incoming parameters to a
/tmp folder, and after I close/open the lid I find these params in txt file:
Thus the param $1 = post and $2 = suspend
If I run the script from terminal:
sudo ./wakeUp.sh post suspend
It runs successfully. So it executes the line where the browser is opened.
If I close/open the lid, the params in wakeUpParams.txt are still
post suspend and the
echo "$@" > /tmp/AfterBrowserLaunch.txt line also executes, but the browser still doesn't launch.
Now to the errors:
When I execute the script via terminal the browser launches but I get errors in the err.txt file:
Home directory not accessible: Permission denied [13870:13961:0316/181921.003202:ERROR:bus.cc(394)] Failed to connect to the bus: Could not parse server address: Unknown address type (examples of valid types are "tcp" and on UNIX "unix") (chromium-browser:13870): LIBDBUSMENU-GLIB-WARNING **: Unable to get session bus: Unknown or unsupported transport 'disabled' for address 'disabled:' [13870:13870:0316/181922.813336:ERROR:gpu_process_transport_factory.cc(1009)] Lost UI shared context. [13968:14061:0316/181923.018813:ERROR:cmd_buffer_helper.cc(158)] ContextResult::kFatalFailure: CommandBufferHelper::AllocateRingBuffer() failed
The out.txt is empty.
When the lid is closed/opened:
- out.txt - empty
- err.txt - empty ( Why no errors here? )
I also execute
chromium-browser --no-sandbox because it wouldn't start without this param from terminal due to some security issues. Is this normal way to start it? Because the browser says in a yellow message pop-out: "You are using an unsupported command-line flag: --no-sandbox. Stability and security will suffer." Is this the best way to execute
chromium-browser from the command-line?
chromium-browser to a simple text editor
gedit and it still won't start even Gedit on open/close lid, while the script from terminal runs without problem... So I suppose it's not a problem with Chromium...
Starting to understand that it's a bad idea to mess with launching GUI from systemd. See Launching Chromium on startup with systemd - Unix & Linux
