Red Hat Bugzilla – Bug 595250
xrandr call crashes the X server
Last modified: 2018-04-11 04:46:44 EDT
This happens with rawhide anaconda boot, but I perhaps it could be reproduced on any rawhide installation.
Steps to Reproduce:
1. boot the installer
2. scp-in rawhide version of xrandr
3. xrandr -d :1 -s 640x480
X server crashes with sigsegv.
definitely not a sigsegv.

This bug appears to have been reported against 'rawhide' during the Fedora 14 development cycle.
Changing version to '14'.
More information and reason for this action is here:
This would be a vmware driver bug before it'd be a pixman bug.
Is this still reproducible in F17?
Unfortunately I don't have access to any VMWare boxes anymore so can't tell. At the time Anaconda used xrandr to manually switch screen resolutions so if this bug still existed in a released Fedora someone else would have run into it too.
I suggest this is closed for insufficient data.
This message is a notice that Fedora 14 is now at end of life. Fedora
has stopped maintaining and issuing updates for Fedora 14. It is
Fedora's policy to close all bug reports from releases that are no
longer maintained. At this time, all open bugs with a Fedora 'version'
of '14' have been closed as WONTFIX.
(Please note: Our normal process is to give advanced warning of this
occurring, but we forgot to do that. A thousand apologies.)
Package Maintainer: If you wish for this bug to remain open because you
plan to fix it in a currently maintained version, feel free to reopen
this bug and simply change the 'version' to a later Fedora version.
Bug Reporter: Thank you for reporting this issue and we are sorry that
we were unable to fix it before Fedora 14 reached 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 to click on
"Clone This Bug" (top right of this page) and open it against that
version of Fedora.
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.
The process we are following is described here:
