I don't know that it didn't happen before 5.2. I bought a used Dell Latitude D530 to load 5.2 onto, and most things work except when I installed xscreensaver I find that about 1/3 of the individual screensaver programs crash. The main program just says "no preview available" but when I quit that there were dozens of .core files left behind in the current directory.
Obviously having xscreensaver isn't a life or death issue but it's kind of fun once in a while. They terminate with a signal 11 (I forget where I found that out, it's in my notes from yesterday). There's also a longish error message on a graphics screen that points to /usrX11R6/lib/modules/dri/i965_dri.so no matter which one crashes. Not much to go on probably, but anyone else seeing this?
