Created attachment 521882 [details] output of xrandr after startup Here xorg.conf contained the single screen configuration as described on http://nouveau.freedesktop.org/wiki/Randr12 Created attachment 521883 [details]
xrandr output after a "xrandr --output DVI-I-2 --right-of DVI-I-1"
executing the command "xrandr --output DVI-I-1 --right-of DVI-I-2" results in displaying the background on the working monitor, the second monitor where the terminal now is, stays black and cycles through the connectors/source. Can you post your dmesg output after booting with both displays connected? Created attachment 522256 [details]
output from dmesg with both monitors connected
This actually comes from /var/log/messages when booting before the proprietary nvidia driver was installed. Please let me know if you need any more details. I'll happily revert to nouveau for further testing.
Thanks,
Niels
Thanks Niels, That log had the information I was after in it, so that's fine! Unfortunately, it didn't actually reveal any good reason why the second display wouldn't work. If you get a chance, are you able to (using nouveau) boot with "log_buf_len=1M drm.debug=14 nouveau.reg_debug=0x600 3" in your kernel boot options? It probably isn't necessary to uninstall the binary driver for this btw, if you boot with the above options, login to the text console and "modprobe -r nvidia nouveau; modprobe nouveau modeset=1", then grab dmesg, it should also suffice. Thank you! Created attachment 522341 [details]
dmesg with additional debug options set
Rebooted, set the options, unloaded the nvidia driver and modprobe'd nouveau.
WFM with the new kernel kernel-3.4.4-4.fc16 Also switching off ACPI at boot time seems to be a workaround for this (even with older kernels). This message is a notice that Fedora 15 is now at end of life. Fedora has stopped maintaining and issuing updates for Fedora 15. It is Fedora's policy to close all bug reports from releases that are no longer maintained.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 '15' 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 15 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: http://fedoraproject.org/wiki/BugZappers/HouseKeeping |
