Hello Leo,

About using https://wiki.ubuntu.com/X/Troubleshooting as a guidline for
adding meaningful informations : the only entry point in this document,
matching my case, is :

"Problem results in X crash or exit"

however, the only suggestion is to run "gdb to get a backtrace" : well,
what process should I run under gdb : X ? and unfortunately I have not
been developing for years, so using gdb as an expert in order to report
valuable information, as stated by this paragraph, is clearly beyond my
current abilities - and additionally, I am not sure it would actually
help : what if X is not the true culprit ?

I don't know what you think about it. My initial intention, as I stated
in my first post, was to follow the guidelines provided by

https://wiki.ubuntu.com/X/Backtracing

I saw in there many interesting suggestions, and my feeling was that
these are general and broad enough, and they would be more useful in
order to deal with a random and unknown problem.

What is your opinion ?

Currently, my best starting point is the backtrace from Xorg.0.log, also
found in the kdm log or in the gdm log :

Backtrace:
0: /usr/bin/X (xorg_backtrace+0x28) [0x4a3258]
1: /usr/bin/X (0x400000+0x655bd) [0x4655bd]
2: /lib/libpthread.so.0 (0x7f025f381000+0xf8f0) [0x7f025f3908f0]
3: /lib/libc.so.6 (__select+0x13) [0x7f025e138fc3]
4: /usr/bin/X (WaitForSomething+0x1ba) [0x45f98a]
5: /usr/bin/X (0x400000+0x30952) [0x430952]
6: /usr/bin/X (0x400000+0x261aa) [0x4261aa]
7: /lib/libc.so.6 (__libc_start_main+0xfd) [0x7f025e078c4d]
8: /usr/bin/X (0x400000+0x25d59) [0x425d59]

Caught signal 3 (Quit). Server aborting

Other people posted the same backtrace, unfortunately it seems that this
same backtrace is dumped for different issues - so what was good to them
was no use to me.

Best regards
R. Grasso
