http://ubuntuforums.org – To start, I'll say that I have all the latest updates installed for 12.04 and the most current stable nvidia driver release by the x-team. I'm running Twinview mode in the nvidia-settings to achieve a dual monitor layout for my dell computer monitor and samsung tv. It seems to work just fine for the most part, but the samsung tv instantly dims a lot just mere seconds after it connects. I've been searching for hours and I've come up completely dry. What I do know is that the only way I've been able to adjust brightness on either is via nvidia-settings because the slider in ubuntu settings and (Hardware)

Nvidia Twinview issue 1 year 44 weeks ago

I am running 2 monitors (well technically, one is a TV, the other is a monitor) on my desktop, and every time I set up the TV using nvidia-settings for twinview, some part of the screen ends up off the TV.  The problem lies soley with the TV, and not my original monitor.  I also am running the same driver on my laptop, and it has the same issue with this TV, and another TV I have used.Be

Broken NVidia X driver 23 weeks 3 days ago

Today I installed the daily updates and then a funny thing happened... I was playing Morrowind on Wine, and in the game I tried to navigate to the video settings menu to adjust the brightness. I had done this before many times with no problem. As soon as I clicked "video", the game silently crashed and returned me to my desktop.

Hi all,

I have a workstation connected to four monitors via the NVIDIA Quadro NVS 450 running "NVIDIA accelerated graphics driver (post-release updates ) (version current-updates)". One of the monitors should be rotated by 180° (inverted).

Graphics Card: NVidia 460 GTX.

Driver: NVIDIA accelerated graphics driver (version current)

I have one DVI monitor, an old Dell LCD from 2005, and one VGA monitor, an Asus ML238H from 2010 whose HDMI port broke. The Asus is plugged into my graphics card's primary monitor slot and is the better monitor even though it is VGA but my computer defaults to the Dell.

Debian 6.0.6 Kernel: Linux nardev 3.2.0-0.bpo.3-amd64 NVIDIA Driver Version: 295.59 Monitor #1: acer 22" 1680x1050 Monitor #2: acer 19" 1440x900

Goal is to make them work in TwinView one next to another.

Monitor #1 is connected to regular VGA port and I can set it normally via nvidia-settings.

Monitor #2 is connected via mini displayport, through some cheap "mini d

I'm running up Jaunty, my laptop is one of the VAIO series with the Video card using the 180.44 closed driver. I found that I can't adjust my brightness with the GNOME applet, it tells me "cannot get laptop brightness" and moving the slider does nothing.

I'm running Ubuntu 12.04. Today I just purchased a second monitor (I have a Dell U2711 and a 42-inch Sony TV). I'm running the 295.49 proprietary nVidia graphics driver, my graphics card is a GeForce GTX 460.

I am not able to activate "xinerama" with "separate X screens", not sure why.

I am able to use TwinView. This works, although it results in severe tearing on the Sony TV.
