Segmentation fault & X
I apologise in advance for the long message.
I seem to have screwed up xserver (not that it was operating that
well).
I used the Debian packages to set it up, but had trouble getting it to
recognise my "card" and monitor. The best I could get was a purported
640 x 480 screen, except that the message announcing success was (I'm
guessing) four times the size it should have been, the buttons for
selecting xvidtune, etc. were off the screen to the right (as was half
the message). I guessed at where the xvidtune button was, so I could
retune, but it saved the configuration. I could not get xvidtune to
run after that.
I downloaded XF86 3.3.6, and tried to install, but could not get
extract to work, so simply gzip'd and tar'd the files into place.
Clearly a mistake. Attempts to run startx, xf86config, or XF86Setup
now end in error messages.
What is my best course of action, please? It appears to be necessary
to generate two or three scripts or files, but I don't know about the
segmentation fault.
I am very new to Linux, so could be missing something very obvious to
those more experienced.
I have run strace on all three of the apps, and I provide below some
excerpts. I include the open and most stat commands:
