Returning to my machine after spending some time in the kitchen preparing a
chicken risotto I was met with the following:
Couldn't open required GL library /usr/lib/Mesa3/libGL.so.1.2!
gears: error while loading shared libraries: gears: undefined symbol:
xscreensaver: child pid 1165 (gears) exited abnormally (code 127)
Making a symlink from /usr/lib/Mesa3/libGL.1.2.0 to
made the screensaver work. So either the symlink is missing or the app
look for it ;)
I see that the Mesa4 lib has only libGL.1.2 and not libGL.1.2.0
This should all read libGL.so.1.2 etc of course.
This should be fixed in beta4.
