Screen saver missing libGL.so.1

[wmrobins]

After moving up From Feisty to Gutsy, my screensaver won't start. When go to screensaver setting it says:

"The specified library screensaver could not be found.

The diagnostic is:
libGL.so.1: cannot open shared object file: No such file or directory"

And all I can do is click on OK or Cancel.

Any ideas?

Thanks in advance,

I don't think I have any ATI drivers. At least I didn't install them and adept does not show any.

Any other ideas?

As Snowhog said: You need libGL.so.1

I don't think I have any ATI drivers. At least I didn't install them and adept does not show any.

Here (AMD/ATi fglrx driver) libGL.so.x is symlink chain:

:~$ ls -l /usr/lib/libGL.so
lrwxrwxrwx 1 root root 10 2007-10-13 12:40 /usr/lib/libGL.so -> libGL.so.1
:~$ ls -l /usr/lib/libGL.so.1
lrwxrwxrwx 1 root root 12 2007-09-29 18:03 /usr/lib/libGL.so.1 -> libGL.so.1.2
:~$ ls -l /usr/lib/libGL.so.1.2
-rw-r--r-- 1 root root 555292 2007-10-23 21:01 /usr/lib/libGL.so.1.2

When you install your graphics drivers, it should make those symlinks.
What kind of hardware (graphics) do you have ?

Hardware/drivers ?. If you are using opensource (mesa):

Package: libgl1-mesa-glx (7.0.1-1ubuntu3)
A free implementation of the OpenGL API -- GLX runtime

This version of Mesa provides GLX and DRI capabilities: it is capable of both direct and indirect rendering. For direct rendering, it can use DRI modules from the libgl1-mesa-dri package to accelerate drawing.

This package does not include the modules themselves: these can be found in the libgl1-mesa-dri package.

For a complete description of Mesa, please look at the libgl1-mesa-swx11 package.

Okay. It's fixed. I had to load libgl1-mesa-swx11 which, according to the notes is AKA libGL.so.1.

Thanks to all.
