Segmentation error 0x50 when installing Xorg?.

notwork · 2018-03-31 20:27:38

Hello,

It had been a few months since I had updated my system. When I tried to update I got a lot of errors. Usually when this
happens I have been advised to just reinstall. It had been quite a while since I had done a fresh install but having done
it many times before I skimmed the wiki and started installing. Everything whent fine until I tried to install/setup Xorg.
After getting all the packages installed, I tried to generate xorg.conf and ran into a problem. When I tried to gen the
xorg.conf file with 'Xorg :0 -configure' as it says in the Xorg wiki, I got a segmentation fault at 0x50. I got stuck for
a while and was searching arround the web for an answer. I continued to search the web for a solution and eventually went
back and read the wiki (yeah I know RTFM). It stated that xorg.conf was "optional" (yeah I know RTFM) so I continued the
install. Once I was done X came up and everything is ok, but I am wondering why this error occurs in the first place. To
try to track it down I ran the same command on my other virtualbox installs. The same error occurs on my other systems even
though everything else works ok. After searching arround the web I found a post that said the command 'Xorg :0 -configure' is
deprecated. I believe the new command is supposed to be 'X -configure', but when I try it I get the same error.

I know this is minor issue since everything works. I decided to post just in case someone else runs into this issue or
is trying to create xorg.conf for their install.

Searching also lead me to this similar post: https://bbs.archlinux.org/viewtopic.php?id=234485

Here is my Xorg.0.log file showing the error:

This function is "broken" since ages (> 5 years?) and you are absolutely not supposed to use it either.
You most likely don't need any xorg config file and if, adjustments should be done via xorg.conf.d snippets - the wiki probably needs an update itr.

Thanks for replying. Since this function is broken, how would I go about getting the wiki updated to reflect the current setup procedure?

Thanks for the info. Is there any way to get https://wiki.archlinux.org/index.php/xorg updated?

seth · 2018-04-02 17:17:10

Yes, edit the page...
However to prevent any discussion *after* the edit (and because I've little record in editing the wiki), I started that thread.
