Description Assen Totin 2013-01-16 18:55:46 UTC
Description of problem:

During its initialization, X.Org crashes with SIGSEGV shortly after loading SiS driver. As Anaconda relies on X, this makes installation of F18 on machines with such video adapter impossible. (The alternative VESA driver results in only part of the screen visible.)

Version-Release number of selected component (if applicable):

How reproducible:

Every time.

Steps to Reproduce:
1. Get F18 installation image (DVD, Live DVD, netinst...)
2. Create desired media (DVD, USB...)
3. Boot and chose to install F18
Actual results:

When Anaconda starts X.Org, the latter crashes with SIGSEGV.

Expected results:

Normal initialization of X.Org.

Additional info:

In F18 the SiS driver was updated from 0.10.4 to 0.10.7. F17 has 0.10.4 and the driver works correctly. 

Video adapter PCI ID from 'lspci' and 'lspci -n':

Additional Info:
Booting in 'Basic Video' (VESA) does work for me. (The monitor max resolution is very low by today standards... a CRT 1024x768....).

Possible Workaround

I have ran into this bug on CentOS 6.4 x86_64:


CentOS 6.4 is still GLIBC_2.12 (Fedora 18 is GLIBC_2.14) so drivers from Fedora will not work though obviously issue is not related to version of GLIBC (if that is helpful).

But it works if NoAccel option is enabled - add following line in Section "Device":

Option     "NoAccel"             "True"

It works, and detects resolution properly.
Hope it helps!

Comment 3 Assen Totin 2013-04-24 15:05:02 UTC
Looks like this bug is now part of CentOS 6.4. too :-) 

If you're bold enough, here is my guide how to get back a fully accelerated X server on Fedora 18 by compiling an older version of X.org manually. Also works on CentOS 6.4 (tried myself few days ago). 



Comment 4 David Juran 2013-07-23 15:11:00 UTC
I've created bug 987519 for RHEL6 which might well be the same issue.

Comment 5 Fedora End Of Life 2013-12-21 10:25:50 UTC
This message is a reminder that Fedora 18 is nearing its end of life.
Approximately 4 (four) weeks from now Fedora will stop maintaining
and issuing updates for Fedora 18. It is Fedora's policy to close all
bug reports from releases that are no longer maintained. At that time
this bug will be closed as WONTFIX if it remains open with a Fedora 
'version' of '18'.

Package Maintainer: If you wish for this bug to remain open because you
plan to fix it in a currently maintained version, simply change the 'version' 
to a later Fedora version prior to Fedora 18's end of life.

Thank you for reporting this issue and we are sorry that we may not be 
able to fix it before Fedora 18 is end of life. If you would still like 
to see this bug fixed and are able to reproduce it against a later version 
of Fedora, you are encouraged  change the 'version' to a later Fedora 
version prior to Fedora 18's end of life.

Although we aim to fix as many bugs as possible during every release's 
lifetime, sometimes those efforts are overtaken by events. Often a 
more recent Fedora release includes newer upstream software that fixes 
bugs or makes them obsolete.

Comment 6 Fedora End Of Life 2014-02-05 14:57:00 UTC
Fedora 18 changed to end-of-life (EOL) status on 2014-01-14. Fedora 18 is
no longer maintained, which means that it will not receive any further
security or bug fix updates. As a result we are closing this bug.

If you can reproduce this bug against a currently maintained version of
Fedora please feel free to reopen this bug against that version. If you
are unable to reopen this bug, please file a new report against the
current release. If you experience problems, please add a comment to this

Thank you for reporting this bug and we are sorry it could not be fixed.
