Your operating system is using NVIDIA binary driver - version 340.46 as it says in the Additional Drivers utility. Because you also are using NVIDIA Prime, your computer can switch back and forth between the open source graphics driver and the NVIDIA proprietary graphics driver. Nvidia Prime (nvidia-prime) is a way of adding hybrid graphics support to ...

The following has worked: sudo sh -c "echo 1 > /sys/bus/pci/rescan" But first you should be sure that you see your device through direct hardware access. sudo lspci -H 1 worked for me and sudo lspci -H 2 not.

I've just had the same problem, and I think it was some kind of update yesterday (I think this is really strange). So, after booting ubuntu, I went to tty (Ctrl + Alt + F1), and I installed the last nvidia driver I get (write "sudo apt-get install nvidia-" and then hit tab to see the versions available): sudo apt-get install nvidia-331 sudo apt-get install ...

About resolution first of all check if you use correct driver for you graphics card if yes, try this in terminal : xrandr -s 1024x768( change to your resolution) About bar if it is unity try this in terminal : unity --reset or sudo apt-get install dconf-tools dconf reset -f /org/compiz/ setsid unity unity --reset-icons It resets Unity .

Please run the command lspci -nn | grep VGA which should identify what model of graphics processor is recognized by the operating system. From the terminal run ubuntu-drivers devices to show the graphics drivers from the Ubuntu Software Center that are compatible with your hardware, and often it will also identify the recommended graphics driver. You need ...

After many days, perhaps even weeks, I was able to run the graphics card from AMD, and while the hybrid mechanism. I worked on Ubuntu 14.04.1 using the latest drivers from your video card manufacturer. Download the drivers from AMD / ATI.

With the release of Ubuntu 14.10, some of the problems related to this incompatibility issue appear to be solved. I succeeded to make both graphic cards to work as follows: 1) Install Ubuntu 14.10. In my case, I first tried updating from 14.04 but I messed up with the installation. I ended up doing a clean install from an Ubuntu CD. 2) Install the fglrx ...

Try setting your start options to nomodeset, acpi=noapic, and other switches. Here's how: http://ubuntuforums.org/showthread.php?t=1613132 If you're able to successfully boot into a normal session this way, the first thing to do is install drivers for your video card. After that, it should work normally.

Assistance much appreciated. I followed your guidance, reinstalling the driver, and still had the same issue. I decided to do a fresh install with 14.10 today and the problem looks to be resolved. The card is recognized properly and I'm able to adjust to 1920x1080 resolution through the advanced settings in nvidia settings. Thanks for the help!

The boot menu offers a low graphics mode and even a text mode installer in case there's no working graphics driver included with the installation medium. It would be crucial to get your keyboard working so you can select the right mode. The issue is usually a BIOS setting for “legacy“ USB devices, which you can read about in the manual of your ...

Together with the latest proprietary nvidia driver we may also install nvidia-settings from the xorg-edgers ppa. This ensures the setting application matches our driver version. Then we may change the screen resolution from the XServer Display Configuration tab: Note that on installing from xorg-edgers ppa we should take care to only install the nvidia ...

After researching this, I can't find any terminal command that would display the maximum resolution supported by the graphics card. The easiest way to find out is to go to the manufacturer's website. As listed here, under specs, an AMD Radeon HD 7750 graphics card supports a max resolution of 4096x2160 @ 60 Hz per display, so you should be able to upgrade ...

The proprietary fglrx driver (which is what you get from Additional Drivers) is not supported anymore by ATI for any ubuntu newer than 12.04.01. Or for any other linux distro using the same kernel. You should be using the open source radeon driver.

Your computer doesn't have the best graphics anyway; dual core with 3 GB or RAM won't do much. If you want to have Ubuntu run perfectly, I suggest Xubuntu, which is made for computers like yours. Xubuntu is based on Ubuntu and should work with all your programs.

If it is the graphics what are slow, you can also try with the proprietary Nvidia driver (which, as of now, is much faster than the open source one). Or you can try an alternative Desktop Environment, such as XFCE (used by Xubuntu, and way faster than Unity/Gnome/KDE) or MATE.

While using the proprietary driver (as indicated in Hatoru's response) will definitely increase the performance, it will also increase the energy consumption (and therefore decrease the battery life). So, if you want to get maximum performance for applications that require it, and maximise the battery life for the rest, the only option as of now is to use ...

I took courage and I installed the closed source drivers from NVidia. I used the Additional Drivers dialog to do it.

I have to say that the performance ...

The best answer is: install a newer version of Ubuntu, with a recent kernel. Xubuntu 14.04 works great on that computer, and the GPU is never too hot.

You should definitely read the official BinaryDriverHowto/AMD guide. The whole point is to install amd graphics driver first (you are given instructions for that on BinaryDriverHowto/AMD guide), and then apply some fix to be found in here on AskUbuntu, for amd drivers, assuming they won't work fine after reboot. Intel drivers for Ubuntu can be found on ...

Boot into recovery mode and nano /etc/X11/xorg.conf then locate the Device section and find the line Driver and set it to "vesa" Save it and reboot. That should handle most video cards out there and allow you to get your drivers set up. Good luck!

If you have installed drivers for you 'old' card, remove them and revert to the default Ubuntu graphics system. Reboot your computer to ensure that all is working properly.

"Your graphics adapter is not supported by this driver. Installation will not proceed." That reads to me like you downloaded the incorrect driver. You may want to check what you downloaded. Also, did you check the System Settings -> Software and Updates -> Additional Drivers tab to see if Ubuntu already has some drivers for you?
