I would recommend running memtest which comes as an option in the GRUB menu or in any of the Ubuntu Live images. In regards to the huge log files, you can simply grab the important debug lines, like the one you mentioned and remove the files before they eat your space. 10GB log files is too much. I am guessing you are a Desktop user and not a server. In the ...

After reading the CUDA toolkit installation instructions and figuring out some compilation issues of the CUDA toolkit examples (following solution applies to them as well), I found out that cudaminer 746a7733dda9d2b3466c54c149362e4fb205cc3f works when invoked with optirun env LD_LIBRARY_PATH=/usr/local/cuda-6.5/lib64:$LD_LIBRARY_PATH CC=gcc-4.8 CXX=g++-4.8 ...

You can install compizconfig-settings-manager. Open ccsm, and click on the OpenGL tab to change the settings. First, make sure this plugin is enabled. Next, on the "texture filter" setting, change the setting to "Best" Also, go to "General Options" and to the "Display Settings" tab. Make sure "Detect Outputs" is enabled. Then, I'm not sure if it will ...

Okay, so do you recall that I own a Samsung SyncMaster S24B300? One of the reasons it had very bad capability is because Linux doesn't take kindly to "generic pnp monitors" apparently. My copy of that monitor did not come with driver software, and Samsung is still very finicky about giving drivers for anything other than Windows. Install the drivers for any ...

As far as I know the nvidia-xconfig comes with the driver. Therefore, on my 14.04 system I can search for the command in the packages dpkg -S nvidia-xconfig and I get nvidia-331-updates: /usr/lib/nvidia-331-updates/bin/nvidia-xconfig As you see nvidia-xconfig is in the package the provides the driver. Which one do you want to install and how?

Use a command like this lspci -vnn | grep -i VGA -A 12 This will give you details about your VGA controller, if it is the Intel one (which I think it is) then do sudo apt-get install intel-linux-graphics-installer Then run it this should remove the error.

I have the same trouble. Same "_". In my searching for the answer, this works for me: Select "advanced options" on the grub boot menu, and then the second choice (first "recovery mode").

You could try making this the main video card in BIOS. the Acer monitor that is not detecting is connected to the video card through HDMI cable cord It might make it detectable and hopefully the other monitor connected to the other card will work too. There is no harm in giving it a shot because if nothing loads, then you can always just switch it back to ...

Check if your video card driver is installed correctly, by going to system settings, updates, additional drivers. Run Nvidia settings, when GUI opens check on the Nvidia gui how many monitors are detected, press on detect displays from within the gui and see if second display is detected. If that don't work out, check for driver or Linux software that can ...

You can install additional drivers for nVidia graphics adapters (and for other hardware) with ubuntu-drivers-common (formerly jockey). Apparently hardware detection and driver management is now done through a command-line interface: sudo ubuntu-drivers autoinstall For details see https://askubuntu.com/a/9465/175814.

It seems that the file /etc/modprobe/blacklist-nouveau.conf contains the invalid verb alia in line 5 which should probably be alias. Are you sure you copied the code listing from the referred answer correctly?

Try your code/shell script in a terminal to see exactly what it will output. It's probably supplying the double results, then you can troubleshoot it in a terminal. nvidia-settings -query GPUCoreTemp | perl -ne 'print $1 if /GPUCoreTemp.*?: (\d+)./;' Just saw your updated Q, with the output from nvidia-settings it's printing the temperature twice for some ...

Got the same problem. Found the solution over there: OpenGL GLX context is not using direct rendering, which may cause performance problems. (steam) AMD DRIVER Contrary to the solution thread's topic, it's not an AMD issue, but seems to involve all systems running the open-source Gallium3D drivers on Ubuntu 14.10.

I had this happen to me on Ubuntu 14.10 x86_64 with kernel 3.16.0-28 after loading Nvidia 346 drivers. After login I would get the blank Ubuntu background wallpaper and nothing else, no way to do anything. There are many similar problems posted online over the past four years; most of the solutions did not work for me. Attempting to restart unity I got an ...

I had a problem with my MSI Gtx 970 for a while now that I can't figure out. The card outputs to one of my monitors, but not another on the default driver.

It seems a lot of people are having boot issues with the latest update. It appears it has to do with the newest kernel.

I used to run an older version of Ubuntu, some seven years ago, on a machine that had an Nvidia Geforce card installed. To install the proprietary graphics drivers, I had to direct my browser to the nvidia website and select the appropriate options. Now, it seems to me that "GTX 640" may not actually be the card's name. There is no "GTX" 640; however, ...

You could try the process of elimination like this: GT 600 is rather new, so you don't want any of the legacy options. Nouveau is experimental, so you don't want it for day to day use, unless wishing to experiment. Now, the two 331 variants are essentially the same, but the first will stay at the current version, while the second one will be updated, as ...

Kinda stupid that I can't just comment, but whatever. It might be an overscan problem. There should be a 'just scan' option on your TV. If not, it might be an overscanning problem with Ubuntu, which can be set in xorg config settings. Does your mouse 'hit' the top of the screen? Or does it go past the top?

Maybe the display is not the problem. Maybe it is the input device which is part of the screen the Nvidia drivers are rendering to. Check the HID devices which might be present for your touch screen to provide system input. Or, check which ones should be present, anyway, and make sure they are. If you have a mouse and a track pad and a keyboard joystick and ...

If your computer is configured such that you are offered a purple screen at boot time with choices to boot a previous version, you may be able to boot successfully, and once in, uninstall or alter your nvidia drivers.

Laptops often overheat when their graphics cards are used near capacity. This is why gamers typically use cooling pads with them, and also why I recommend everyone use cooling pads all the time.

I ended up downloading the newest drivers straight from NVIDIA from here and installing them manually. Obviously, this won't automatically update in the future (AFAIK). The path I had to take was actually quite convoluted, involving adding the nomodeset flag to GRUB, then killing lightdm, and then running the installer. I followed some suggestions from here ...

It sounds like a bug described at https://bugs.launchpad.net/nvidia/+bug/1401434 A workaround may be to downgrade the nvidia driver 331.113 to 331.38. This helped me: How to downgrade packages on Ubuntu?

Search additional drivers in the unity search box, click to open it. You can enable the proprietary driver there.

I have found the solution to this problem and will proceed with how I came to solve the issue. The problem was not caused by the Nvidia driver or GTK like I originally thought but was due to an old bug in Compiz to do with the screen refresh rate on Nvidia cards as pointed out by Mateusz Stachowski on Google+ who also provided a link to the bug report on ...

Something similar to the original request can be found in the nvidia-prime project. However, after some tests, I decided to get back to optirun. The main reason is that prime keep your nvidia GPU always on, with a lot more power consumption.

Using the .run file will crash your system. Just install the package sudo apt-get install nvidia-331 The "Additional Drivers" menu can't recognise a lot of hardware so that means nothing. The Ctrl+Alt+F1 should have been working. It is a separate problem for you to solve after you deal with drivers.
