[Bug 1457880] Re: dual monitors not working
chenhao, as per http://www.gigabyte.com/products/product-
page.aspx?pID=2892#bios an update to your computer's buggy and outdated
BIOS is available (F6). If you update to this following
https://help.ubuntu.com/community/BIOSUpdate does it change anything?
If it doesn't, could you please both specify what happened, and provide the output of the following terminal command:
sudo dmidecode -s bios-version && sudo dmidecode -s bios-release-date
For more on BIOS updates and linux, please see
https://help.ubuntu.com/community/ReportingBugs#Bug_reporting_etiquette
.
Please note your current BIOS is already in the Bug Description, so
posting this on the old BIOS would not be helpful. As well, you don't
have to create a new bug report.
Once the BIOS is updated, if the problem is still reproducible, and the
information above is provided, then please mark this report Status New.
Otherwise, please mark this as Invalid.
Thank you for your understanding.

Title:
dual monitors not working
Status in xserver-xorg-video-ati package in Ubuntu:
Incomplete
Bug description:
I am using ubuntu 14.04 lts 64bit.
my kernel version is 3.13.0-53-generic #88-Ubuntu SMP Wed May 13 18:10:29 UTC 2015 x86_64 x86_64 x86_64 GNU/Linux.
I have two monitors which are 1440x900 and both have only one vga support.
I video card is NVIDIA Corporation G96 [GeForce 9400 GT] with one hdmi,one dvi and one vga support.
I use one vga(works well) and one dvi (I use a dvi2vga).
First, the two monitors are working well in my windows.
When I was in ubuntu,one resolution is 1440x900 and other one(which use div support) can only choose 1024x768.
I have changed the nvida drivers,there is one driver can ever support 1366x768,but there is no 1440x900.
Through the internet,
I found 'xrandr'.
this can add a 1440x900 mode by munual.
xrandr --newmode '1440x900_60.00' 106.50 1440 1528 1672 1904 900 903 909 934 -hsync +vsync
xrandr --addmode DVI-I-2 1440x900_60.00
xrandr --output DVI-I-2 --mode 1440x900_60.00 --right-of DVI-I-1
It can make both work at 1440x900.
but it was not stable,especially after I locked my screen.
It always crashed or stuck
