Summary0017433: .Xauthority-c and .Xauthority-l lock files generated after using startx command
DescriptionAt boot, our web application is launched by the command startx ( The startx(1) script is a front-end for xinit(1). The xinit program allows a user to manually start an Xorg display server.) and is displayed on the screen.

But sometimes, we get an error just after a reboot : " timeout in locking authority file /home/prescom/.Xauthority " and the web application can't start anymore (even after few reboot). If we manually launch the web application using startx, we get the error "no protocol specified".

After analysis, two lock file are present in the /home/user folder : .Xauthority-c and .Xauthority-l

 Those files are lock files for .Xauthority, so simply removing them resolves the issue.

We need to know Why and how the lock files are generated ?

Thank you for your support,

Since you are not reporting a bug but you are seeking support, I am going to close this bug because the bug tracker is not a support channel. Please seek help in more appropriate venues like CentOS fora, mailing list or IRC.

As a side note, I suspect your application dies leaving around dangling lock files. But it's just an educated guess, the problem might be completely different
