Description Frank Ch. Eigler 2007-11-19 18:36:17 UTC 
Description of problem:
On a pair of 1600x1200 DFP's on my video card, the nv_drv driver
messes up the panel size, and thence the dual-head/virtual size
calculations.

Please note that the nvidia driver does the right thing.
Sadly, something about fedora 8 plus that driver makes the machine
prone to freezing, thus my attempt to use nv_drv.  However, if it
can't drive the panel at the proper resolution, I'm stuck.
Comment 1 Matěj Cepl 2007-11-21 09:03:00 UTC 
Thanks for the bug report.  We have reviewed the information you have provided
above, and there is some additional information we require that will be helpful
in our diagnosis of this issue.

Please attach your X server config file (/etc/X11/xorg.conf) and X server log
file (/var/log/Xorg.*.log) to the bug report as individual uncompressed file
attachments using the bugzilla file attachment link below.

Please, make sure, that no remains of nvidia driver are present on your hard
disk when running the test above (and below for that matter), see
http://fedoraproject.org/wiki/Xorg/3rdPartyVideoDrivers for instructions how to
do it.

Could you please also try to run without any /etc/X11/xorg.conf whatsoever and
let X11 autodetect your display and video card? Attach to this bug
/var/log/Xorg.0.log from this attempt as well, please.

We will review this issue again once you've had a chance to attach this information.

Thanks in advance.

(Same symptoms if the "Monitor" clause is absent or if the "FlatPanel" option
is left at its default "on".)

And this is the Xorg.0.log coming from no xorg.conf.
Comment 7 Adam Jackson 2008-02-11 22:37:59 UTC 
Yep, it sure does.
