I have Ubuntu 11.04 I am trying to install Xvfb and CutyCapt in order to take a snapshot of webpage I followed a instruction https://github.com/jaequery/cutycapt-installer-scri
Run xvfb-run -e /dev/stdout [mycommand]
as @wumpus suggested.
I received the server lock message:
Fatal server error:
Could not create server lock file: /tmp/.X99-lock
xvfb-run:
error: Xvfb failed to start
Using sudo
resolved the issue for me:
sudo xvfb-run -e /dev/stdout [mycommand]
I was getting this error "xvfb-run: error: Xvfb failed to start" on Ubuntu 14.04, where previously my script had run without problems on Ubuntu 12.04.
My scripts were running calling xvfb-run multiple times, but I was seeing fails due to the error "Server is already active for display 99"
It seemed that the Xvfb wasn't ending when the xvfb-run command returned.
My solution was to use "xvfb-run -a [mycommand]"
so xvfb uses another display if 99 is in use.
Found the problem There is hanging process in system with name
Xvfb
I killed it and work fine. I newer found it earlier beacuse I used to try to find process with 'xvfb' name
Had the same issue, solved it by running this instead:
xvfb-run --auto-servernum --server-num=1 [your script]
--auto-servernum : Try to get a free server number, starting at 99, or the argument to --server-num
