Screenshot is blank from an VM instance without an open RDC connection

GoogleCodeExporter commented 9 years ago

What steps will reproduce the problem?
1. Set up a Windows 7 virtual machine that runs Selenium standalone server with 
ChromeDrive2 v0.7.
2. Open a connection to this VM using Remote Desktop Connection.
3. From your dev machine execute a test (towards the Selenium server in the VM) 
that loads a site and takes a screenshot.
4. Close the RDC connection to the VM.
5. Execute the same test again.

Simplified test case or site demonstrating the problem:

For step 3. we get a proper screenshot.
For step 5. we get a black screenshot.

What version of the product are you using? On what operating system?
Selenium = 2.32.0
ChromeDriver = 0.7
Chrome = 26.0.1410.64
OS = Windows 7

See chromedriver.log attached for both cases.

Thanks for the report. Can you try ChromeDriver2 and see if it has the same 
problem?

The issue is in fact present with the ChromeDriver2_win32_0.7.zip, but it is 
not present with the ChromeDriver_win_26.0.1383.0.zip

The issue is still present with ChromeDriver2_win32_0.8

The VM used for this test was running on a local OpenStack.

Got same issue. I got a remote machine where the selenium jobs run. After 
disconnect from Windows Remote Desktop, the chromedriver2 only takes black 
screenshots.

Same issue.
Running script in Jenkins takes a blank screen shot.
Running script on local machine takes snapshot of webpage, as expected.

Was using ChromeDriver_win_26 previously, and running script in Jenkins 
produced snapshot of webpage, as expected. Nothing else changed in environment 
expect the upgrade to ChromeDriver2

We are having the same issue. VM's running a Teamcity agent. Capture 
screenshots is giving us black captures only.

Same here, IEDriver and ChromeDriver just black screenshots, only Firefox works 
as expected and doing full screen shots (not only the visible part).

Is there any workaround or plans to fix this issue? It makes Chrome Driver 2 
basically unusable on a CI server.

I've found no workaround.  I see the issue has bee accepted.  I can only hope 
someone picks this soon and codes a fix.

The issue has to do with how Windows handles device rendering with a 
disconnected session.  Firefox doesn't have the problem because they have a 
special extension to canvas that renders to a screenshot.  A workaround is to 
run a VNC server and leave the session logged in.  Auto-login for your CI 
agents would probably be your best bet.

This may be the case, but this worked in chrome driver 1.0.  The reports above 
indicate this started failing chromedriver 2.X.  So we do know that it possible 
to get the screenshot in a headless environment over Windows.  It would be 
really good to get a fix for this.  Leaving a VNC server with a logged in 
session is not a good workaround.

This issue is now a blocker for us, since the current Version of chrome (29) is 
not working with the old (26.0.1383.0) driver anymore (Fails with "Unknown 
command 'WaitForAllTabsToStopLoading'")

This is now a blocker for my team as well, as we run watir tests in Jenkins on 
multiple remote VMs and rely heavily on screenshots as part of our acceptance 
testing, and Chromedriver 26.0.1383.0 does not work with Chrome 29.

Voting up.  We were forced to go to chromedriver2 for chrome 29 and as with 
everyone above it broke our screenshot capability.  Screenshots on non-RDC VMs 
are critical to our CI.  Please fix the regression!

We have a remote server farm to run our tests and this bug has blocked our

Experiencing the same issue after upgrading to chromdriver v2.2

When getting error as below, the screenshot is blank.

In my case... we run the tests using a Windows Service in a server and with 
chromedriver 2.2, always blank (white) screen but not if you run the test in a 
local machine. 
We were using before the chromedriver of january 2013 and working fine... but 
we upgraded to 2.2... :(
It is really important for us to be able to take screenshots... is this gonna 
be fix?

Thanks.

I met with this problem while trying to take screenshot of chrome by teamcity 
agent (on remote server) run as localservice.
The solution was to use remote desktop to run the agent from console and then 
close remote desktop connection. Then it works fine! This is just workaround 
but it enables usage of this driver.

Screenshots are working for the most part on Windows with Chromedriver 2.3, but 
I'm occasionally getting the following error, which is causing some failures in 
some of our tests.  So far it seems most likely to occur when trying to handle 
popup windows.

Hi ..

 I am facing similar kind of issue. I am running my webdriver test in a remote VM with IE 9. After starting the execution, I am closing the remote desktop session.

But I found the screenshot as blank while verifying the report after completion 
of execution.

Can anyone please find me a solution?? 
Thanks & regards
