Created attachment 673579 [details] Xorg log file When trying to enable an extra disaplylink monitor in KDE, X is crashing as soon as the 3rd monitor is enabled. Laptop w/ docking station and Displaylink usb adapter. In KDE, the 3rd monitor will show connected in the Display and Monitor section of settings, but disabled. Enable the monitor by changing the drop down to a resolution and hit Apply. Instant segfault. Attached is a Xorg.log and a screenshot of the description.

I should also note that when starting X, the monitor is "enabled", but the screen is black, the desktop does not extend to it.
Disconnecting everything, rebooting the laptop and just trying to hotplug the display link shows the same behavior. Connected monitor switches to "enabled", window manager extends (as in I can drag windows over to the black screen and loos them forever), but screen remains black.
nouveau driver issue, more chance to get noticed
How is this a nouveau issue?
My main display is nouveau, is the suggestion that it is somehow blocking the displaylink device?
xorg-x11-drv-nouveau-1.0.6-3.fc18 has been submitted as an update for Fedora 18. https://admin.fedoraproject.org/updates/xorg-x11-drv-nouveau-1.0.6-3.fc18

Using xorg-x11-drv-nouveau-1.0.6-3 and xorg-x11-drv-nouveau-1.0.6-4 produces the same behavior. I have attached another Xorg.log, at 1337.162 is when I hotplug the displaylink adapter in. In addition I have attached a screenshot from krandr. The displaylink interface (DVI-2) is getting displayed on the laptop screen (LVDS-1). The strange part still is that the monitor connected to the displaylink adapter stays black but is powered up out of power saving mode.

I was able to undock the laptop and try some basic extending with xrandr with only the laptop display and displaylink adapter. When issuing the xrandr command to make the displaylink adapter "right-of" the laptop, it crashes X. Log with backtrace has been attached.
is there anything in dmesg? as the nouveau driver is failing to enable accel, which causes the later crash, (I think I might have fixed that crash in newer -modesetting and server I haven't pushed yet, but it still won't work without accel).
Package xorg-x11-drv-nouveau-1.0.6-3.fc18: * should fix your issue, * was pushed to the Fedora 18 testing repository, * should be available at your local mirror within two days. Update it with: # su -c 'yum update --enablerepo=updates-testing xorg-x11-drv-nouveau-1.0.6-3.fc18' as soon as you are able to. Please go to the following url: https://admin.fedoraproject.org/updates/FEDORA-2013-2093/xorg-x11-drv-nouveau-1.0.6-3.fc18 then log in and leave karma (feedback).
I get the following in dmesg when reproducing the crash. nouveau W[ PGRAPH][0000:01:00.0] disabled, PGRAPH=1 to enable
Adding nouveau.config=PGRAPH=1 to kernel boot options enables acceleration when starting X. Bad news is that X will crash a few seconds after it starts up. New backtrace is in attached log.

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.
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 bug.
