I recently installed Ubuntu Linux 15.10 on a Lenovo desktop.After a mysterious crash last night while testing point and click of an Mono-.NET 4.5 C# executable which DLLImport's an C++ shared object, the Files GUI manager , /usr/bin/xdg-open , flickers on and off . I removed the package xdg-utils and then installed it again followed by a system reboot and the Files GUI manager , /usr/bin/xdg-open , * still * flickers on and off.

   I goofed up. Nautilus is the file manager. An Xamarin expert advised I have driver issues.
so that either I force the system to disable 3d acceleration (the GUI is 3d accelerated by default), or I should change your graphics card, or I might have to update the driver.

   How do we force Nautilus to disable 3d acceleration?

  Please advise me how to fix this problem. Any help is greatly appreciated

You could try

 
sudo apt-get update
sudo apt-get upgrade

Open in new window


After that reboot and check if the issue is resolved.

But personally I wouldn't use Ubuntu, it's Unity user interface is terrible to use and slow, and it is very hardware resource hungry. There are far better linux distro's, the best currently is MakuluLinux, which has an Aero (UI that resembles Windows 7, but it also needs a good GPU) and the XFCE version which needs less hardware resources. Both are much faster and more reliable than Ubuntu, and they are based on Ubuntu/Debian, so you can install software for those distro's easily.

@rindi, Thanks  for your help.

I am about to test

sudo apt-get update
sudo apt-get upgrade
reboot


What else should I try if this doesn;t stop the blinking problem?

As I said, don't use Ubuntu... or change from unity to something like XFCE.

@rindi,
       I must use Ubuntu because our customer is required to use Ubuntu.

I just tried sudo apt-get update followed by sudo apt-get upgrade followed my reboot and it did not fix the problem

      May I ask how to fix the Nautilus File Manager driver problem?

     Thank you for your expertise.

It's unlikely to do with nautilus. What GPU does your PC use? If it is a Radeon or NVidia, did you install the legacy drivers?

Besides, can't it be Xubuntu or Lubuntu? Those at least have usable desktops. Or install the XFCE4 desktop alongside unity, and then work inside XFCE rather than unity.

@rindi,
 Thank you for your expertise in linux systems integration.
 I will accept your solution soon.

As shown below , my PC uses the Nvidia GPU.
 
venkat@venkat-ThinkStation-S10:~$ lspci | grep VGA
01:00.0 VGA compatible controller: NVIDIA Corporation G86 [Quadro NVS 290] (rev a1)
03:00.0 VGA compatible controller: NVIDIA Corporation G86 [Quadro NVS 290] (rev a1)

How do I tell if I previously installed Nvidia * legacy * drivers?

How do I install the new generation of Nvidia drivers on top of the  Nvidia * legacy * drivers?

How do I install the XFCE4 desktop alongside unity, and then work inside XFCE rather than Unity?

Check if there is a separate driver utility in Ubuntu. Many distro's have something like that, but I don't know about Ubuntu. If it has such a thing, start it and it should look for hardware for which legacy drivers exist. You can then select the driver and it gets installed.

If there is no such driver utility, open the Synaptic Package manager and enter nvidia in the search box. It should then show all nvidia software, and if it it is marked green then it is installed. The latest version for your card should be something like 340.96. If it isn't marked green, but available, you can select it to get it installed.

Another way to install it is to go to the nvidia site and download the driver, then follow the installation instructions there to get it installed. This usually works better than using synaptic for the installation, but it is more complicated. The driver utility also usually works well.:

You can install XFCE4 also with the package manager. Just select XFCE4 and mark it for installation, or xubuntu-desktop (this adds further typical XFCE tools so you get the Xubuntu Desktop).

To logon to XFCE4, you first need to log out (or reboot), and then on the login page you should somewhere be able to select which desktop you want to log on to.
