webscreensaver xscreensaver combination not working CentOS 9

Open strangmann opened this issue 2 years ago • 4 comments

Hi there,

My plan is to use xscreensaver with webscreensaver to display a website during inactivity in some CentOS 9 clients. I have installed the following packages:

  • xscreensaver-base-6.05-3.el9.x86_64
  • xscreensaver-extras-6.05-3.el9.x86_64
  • xscreensaver-gl-base-6.05-3.el9.x86_64
  • xscreensaver-gl-extras-6.05-3.el9.x86_64
  • xscreensaver-6.05-3.el9.x86_64
  • gtk3.x86_64
  • gtk3-devel.x86_64

I downloaded the following script to a directory on my system: https://raw.githubusercontent.com/lmartinking/webscreensaver/master/webscreensaver.

After that I tested if I could open websites with webscreensaver and it worked. The xscreensaver sample screensavers also works, but the combination of the two does not work. After xscreensaver & I get a black screen, but the webscreensaver command is running.

Could you please help me?

I'm running in a virtual machine, but the dedicated clients aren't working either.
