BENQ BL2400 Screen doesnt work with higher resolutions after installing Nvidia drivers on Ubuntu 14.04
I have a dual screen setup on Ubuntu 14.04 that I just installed. The graphics card is a GeForce 8800 GTS. When using t he default Nouveau driver all works fine displaying high resolution desktops on both screens. But when installing and changing to the Nvidia driver, my second screen (BENQ BL2400) appears as type unknown and can only display 800x600 as the highest resolution. I would like to fix this.
The Nvidia driver that I chose is version 331.113 from nvidia-331-updates (proprietary).
I also tried version 340.65 from nvidia-340 (open source), but that made me not only loose picture on my BENQ screen but also the whole desktop lag on the main screen. I am using 331.113 now, and the only problem with that driver is what is described so far.
Judging by http://www.nvidia.com/Download/index.aspx the right driver should be 340.65 (Geforce 8800 GTS on Linux 64 bit). It can be downloaded from here:

Offcourse, this then fails:
All help appreciated :)

Did you create the newmode with xrandr --newmode first? Besides that, is the display connected directly to the video card's output, or is there a KVM switch or something similar in between? I have often seen this happen with such switches, so connecting the display directly to the PC without the switch may help.
Here you have my attempts:
How do I know what screen cvt is getting information for? Seems like the new modes are only added on the working screen.
In this case the working screen(no problem screen) is connected to a HDMI switch with a HDMI to DVI cable (DVI in the screen end). The cable from to the HDMI switch is DVI from the computer to HDMI in the switch. The screen that I am not getting to work, the problem screen here, is connected directly to the graphics card with a cable that is DVI in both ends.
The trouble screen is DVI-I-2.

CVT doesn't get the value from any specific monitor.
Check whether an /etc/X11/xorg.conf file was created, and delete it if it is there (or rename it), then logoff and logon again (or reboot), then try the xrandr commands again.
If there is no such file, look for the nvidia configuration utility, and check if you can set the resolution for the 2nd display there. This will create an xorg.conf file, which you'd then copy to the /etc/X11 folder.

Nvidia X Server settings show exactly the same problem - when not choosing auto 800x600 is the highest I can pick:
Tried rebooting also. I had rebooted before, so it didn't surprise me that it didn't change anything.
I switched to the nouveau driver again, and then things look like this - both screens work(but I want the nvidia driver to work):

Why do you need the legacy driver? I've found that the nouveau driver usually works very well.
How did you install the legacy driver? did you download it from the nvidia site, or did you use Ubuntu's built-in driver utility to get it directly from it's repository?

This thread is getting pretty lengthy, all your answers are in it esxcept the one where you ask why I want to use the nvidia driver. The way I have understood it, the nouveau driver is just an all around driver that ships with ubuntu to suit a wide range of graphic cards. It doesn' provide the functionality specific for the graphic card in question. The newest nvididia drivers aren't legacy as far as I know, they are the available drivers appropriate for the card. When playing 3D games, the performance is clearly better with the nvidia drivers as far as I have seen then with the nouveau drivers. From my experience I have tried Half-Life, Half-Life 2 and MineCraft. It might be different on this exact card, as i have not had time to try all this out on exactly this card.
The nvidia drivers were installed via the aptitude package system. There is a link in this thread to the guide I used. I have tried all the various drivers from nvidia that came with the install, and they all fail the same way, except the latest driver which in addition lets the xserver show the error: "could not set configuration for crtc 583" and then everythin goes to an almost freeze in the window system.
While waiting now recently I tried unimstallin all nvidia drivers and install the nvidia driver from the nvidia web site using the run file. It then told me that the proprietary check scripts failed(or something in that order). I installed anyway and found the same error then also, my other screen not working.
In the end I uninstalled this driver from the system by running the run file and adding the argument -uninstall. After this was done, I can log in to the x system - but nothing is displayed other then the desktop background (on both screens in right resolution). So i will just reinstall Ubuntu tomorrow I guess. Maybe just give up the whole nvidia thing.

Could be the drivers aren't ready yet. I don't play games (except maybe some simple card and mahjong type games), so I wouldn't be able to say anything about that. I do use nvidia drivers though, but those are for older cards and also the drivers are older. I haven't really seen much difference in performance between these nvidia drivers and the nouveau version.

When using the nouveau driver for desktop experience, there propably is no difference.
Here is a recent test using various games and nvidia graphics cards to see the difference between nouveau and the nvidia drivers. It concludes as I suspected that the nouveau driver is not as good when it comes to 3D graphics:

Your graphics card is one generation older than ones benchmarked in the link you provided.
You can always compare yourself http://www.geeks3d.com/gputest/
Did you disable nouveau before installing any nvidia drivers? If nouveau is loaded nvidia-xconfig just makes wrong config files.
Lets start anew. Lets return to the system as it was installed
lsmod| grep -e nouveau -e nvidia
? anything? both? and after reboot?
remove any nvidia package, leave nouveau untouched
REBOOT
install dkms
(nvidia replaces these files, system updates replaces them again)
reinstall mesa-libGL
reinstall xorg-x11-server
REBOOT
run some benchmarks and record the results.
Now download 340.65 run file
Exit into text console by "service lightdm stop"
Follow instructions in nvidia installer to disable nouveau driver, probably it will take reboot or two before it says it is safe to install the drivers.
Once nouveau is disabled you can use any system packages, but also you can install same driver from run installer.
Run benchmarks again - is there any gain?

I have already reinstalled Ubuntu, and I could make a fresh attempt on the 340.65 run file, but considering the time I have spent on this so far and the statement in the following link, I will save that for later:

While you are with your reinstalling hand on the keyboard - make sure you have DKMS installed before installing .run driver. That will allow driver to survive kernel updates.
