Log says "Caught signal 7 (Bus error)" I installed Ubuntu with Mate as the GUI for a friend, the computer is an Asus S301L. It worked fine for a while, but then he said that it was failing to boot. He says he didn't do anything other than updating the system as requested by the update manager. What happens is that the starting screen - the one with all the [OK] statuses - flashes a few times, then I get a text login prompt and a line saying the crash report daemon has been started. I can login in text mode, and reading Xorg.0.log I find that error. If, at this point, I manually do startx, the GUI does start and autologin, but it's all broken - the panel doesn't appear, for instance, and alt+f2 does nothing.

Segmentation faults occur when accessing memory which does not belong to your process, they are very common and are typically the result of: using a pointer to something that was deallocated. using an uninitialized hence bogus pointer. using a null pointer. overflowing a buffer. PS: To be more precise this is not manipulating the pointer itself that will cause issues, it's accessing the memory it points to (dereferencing). share|improve this answer edited Oct 17 '08 at 15:18 answered Oct 17 '08 at 15:12 bltxd 5,68322336 52 They aren't rare; I'm just at Exercise 9 from How to Learn C the Hard Way and already encountered one... –11684 Mar 26 '13 at 20:12 5 Another cause of bus errors (on Linux anyway) is when the operating system can't back a virtual page with physical memory (e.g. low-memory conditions or out of huge pages when using huge page memory.)
