+++ This bug was initially created as a clone of Bug #923888 +++ Description of problem: My laptop uses optimus and is wired so one of the external monitor ports is on the nvidia chip. Due to this I have testing packages enabled so I can use nouveau output provider PRIME support. I have 2 external monitors connected, one to VGA via the intel chipset (VGA2), and one to DVI via the NVIDIA chipset (DP-2) . I am also trying to use 2 DisplayLink monitors in addition (DVI-0 and DVI-1). I ran these commands to set up my monitors, and had the crash on the last one: [ben@localhost ~]$ xrandr --output DP-2 --auto --right-of VGA2 [ben@localhost ~]$ xrandr --output DVI-0 --auto --left-of VGA2 [ben@localhost ~]$ xrandr --output DVI-1 --auto --left-of VGA2 [ben@localhost ~]$ xrandr --output LVDS2 --auto --below VGA2 [ben@localhost ~]$ xrandr --output DVI-1 --auto --left-of VGA2 [ben@localhost ~]$ xrandr --output DVI-1 --off [ben@localhost ~]$ xrandr --output DVI-0 --off [ben@localhost ~]$ xrandr --output DVI-1 --auto --left-of VGA2 [ben@localhost ~]$ xrandr --output DVI-0 --auto --right-of DP-2 Floating point exception (core dumped) [ben@localhost ~]$ xrandr --output DVI-0 --auto --right-of DP-2 Floating point exception (core dumped) [ben@localhost ~]$ xrandr --output DVI-0 --off [ben@localhost ~]$ xrandr --output DVI-0 --auto --right-of DP-2 Floating point exception (core dumped) Version-Release number of selected component: xorg-x11-server-utils-7.5-16.fc18 Additional info: backtrace_rating: 4 cmdline: xrandr --output DVI-0 --auto --right-of DP-2 crash_function: preferred_mode executable: /usr/bin/xrandr kernel: 3.8.3-203.fc18.x86_64 uid: 1000 Truncated backtrace: Thread no. 1 (3 frames) #0 preferred_mode at xrandr.c:901 #1 set_output_info at xrandr.c:1172 #2 get_outputs at xrandr.c:1833 --- Additional comment from Arcadiy Ivanov on 2014-03-08 00:39:16 EST --- Same issue occurs on Fedora 20: 3.13.5-200.fc20.x86_64 #1 SMP Mon Feb 24 16:51:35 UTC 2014 x86_64 x86_64 x86_64 GNU/Linux Please reopen --- Additional comment from Arcadiy Ivanov on 2014-03-08 00:42:24 EST --- Package is xorg-x11-server-utils-7.7-2.fc20 xrandr --output eDP1 --auto Floating point exception (core dumped)

This message is a reminder that Fedora 20 is nearing its end of life. Approximately 4 (four) weeks from now Fedora will stop maintaining and issuing updates for Fedora 20. It is Fedora's policy to close all bug reports from releases that are no longer maintained.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 EOL if it remains open with a Fedora 'version' of '20'. 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. Thank you for reporting this issue and we are sorry that we were not able to fix it before Fedora 20 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 this bug is closed as described in the policy above. 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.
Fedora 20 changed to end-of-life (EOL) status on 2015-06-23. Fedora 20 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 bug. Thank you for reporting this bug and we are sorry it could not be fixed.
