Graphics cards help with: CUDA/OpenCL style workloads (eg bitcoin mining) 3D rendering. You might be rendering stuff on demand. Most cards can help with video decoding but this applies to many IGPs too. Some cards have hardware to help with video encoding. The quality is usually a lot poorer and this is still under development. ffmpeg can use nvenc ...

That software checks /etc/lsb-release and that is a text file we can edit ourself so it might be fairly easy to circumvent. Make a backup first though if you do not know what this means. From a command line: sudo cp /etc/lsb-release /etc/lsb-release.backup And then edit the file ... sudo gedit /etc/lsb-release And change the lines as below: ...

On some computers the new versions that are installed with the intel-linux-graphics-installer have those exact same issues, I had it happen with two netbooks so it dosn't seem to be a conflict between nouveau/intel but a problem with the newer graphics installed from Intel. First you need to remove the source that Intel installed automatically when you ran ...

I think I found the fix. Source: https://bugs.launchpad.net/ubuntu/+source/xorg/+bug/1314367/comments/22 so far so good. I'll update this if it starts flickering again. For those that are wondering, you need to install compizconfig-settings-manager first from terminal. sudo apt-get install compizconfig-settings-manager Open it and go to workarounds and ...

If we were talking about outside video, I would make a simple SVG in inkscape with a placeholder string like OLISTRING, get it how I want it to look then manipulate that on the command line to substitute my dynamic text in. And use Inkscape to rasterise it. inkscape -z -e intro.png -w 1920 -h 1080 <(sed 's/OLISTRING/My Video!/' drawing.svg) The real ...

Thanks all for your support. Luke put me on a track that solved the problem in a easy way. The issue relates to issues using SNA (Sandybridge's New Acceleration) with the Intel Graphics and need to revert back to UXA (Unified Acceleration Architecture). The way to do this is pretty simple: Put the following: Section "Device" Identifier "Intel Graphics" ...

I found a solution: installed Imagestick: sudo apt-get install imagemagick And then I used something like: convert -pointsize 36 -fill red -draw 'text 10,10 "Loh pidr text" ' b.png test1.jpg And then use man convert to see documentation and play aroud.

I installed a Lenovo Z50-70 laptop two days ago with an Intel HD 4400 integrated and with this Nvidia Geforce 840M GPU. I installed an Ubuntu 14.04 trusty thar on it (from an usb stick with UEFI boot). The system worked with the intel vga by default, yes, a current nouveau driver can't recognise the Geforce 840M. The easiest sollution to work with it: In ...

Depending on the way you've set up your system it might be as easy as copying the monitors.xml file from the correctly set-up user to all users: Test for one user: cp --preserver=timestamps /home/CorrectUser/.config/monitors.xml /home/TestUser/.config/ then log off TestUser, log back on and see whether everything is correct. Now do for all users: cp ...

According to this Romanian Website, you should be good! EDIT: Model number on the laptop itself is slightly different, but the graphics card is the same model so laptop model shouldn't make any difference. EDIT 2: So, it was clarified that this is a certified (pre-installed) rather than a certified installation, meaning there could have been modifications ...

This kind of error is usually caused by memory issues. My 8 year old laptop also has similar issues when I have a lot of tabs open on chrome(around 15 tabs) and when the system uses a lot of RAM. I use indicator-multiload to see how much RAM is used. My laptop only has 2.5 GB of RAM and also has an integrated graphics card. My guess would be that the ...

Yes if the server generates or, for instance, re-sizes images. Software that uses, or could use, the existing graphic card for such tasks, is not unheard of. Surely, this depends a lot on what kind of software, what kind of GPU, is the suitable driver available and things the like.

I had a very similar problem and spent several days trying to get my card working. I have an ASUS X550LN which has an Intel Graphics Driver on the CPU and a dedicated NVIDIA GEFORCE GT 840M. First, installing the nvidia-340 drivers would cause Unity and Gnome to fail when launching. I could drop to a shell Ctrl + Alt + F1 and remove the driver sudo apt-get ...

No you do not nedd extra drivers, these should be fine. Bonaire is a code name for a certain chip. AMD and Nvidia do a whole lot of re-branding of older models on a yearly basis (because OEMs force them to come up with updated model numbers that suggest significantly more performance), so don't be confused when you find this code name in earlier generations. ...

I just installed Ubuntu 14.04 Desktop on Hyper-V and was facing the same problem with performance. Later figured out that Hyper-V allocates 1 Virtual Processor to each Virtual Machine by default. Increased it to 4 and its working fine now.

Most of the open source drivers you'll find may produce better graphical output than the proprietary do. Sometimes you won't even notice a difference. And sometimes an open source driver works much worse than the proprietary one. I will not make a general recommendation on which to use, but here are some cases, in which certain drivers are better than ...

My understanding is that the nVidia drivers are significantly better at 3D acceleration and shading, but are about the same as the open source drivers for 2D applications. See this comparison for some concrete benchmarks. Proprietary (usually) beats open source in terms of performance. That being said, upgrading is significantly easier and more ...

You don't always need to use a IDE you can just develop using a simple text editor like ("gedit" on ubuntu). But if you're looking specifically for an IDE there's the "Bluefish" editor that can help you in the development but there are many others also. Since you're gonna be developing PHP websites you'll need a server and probably a database software if ...

There is a known bug to nvidia settings: Bug #1341140. If you receive the following error message, you are probably affected by it: ERROR: nvidia-settings could not find the registry key file. This file should have been installed along with this driver at either /usr/share/nvidia/nvidia-application-profiles-337.25-key-documentation or ...

Having pstate enabled may actually give you better performance, however, switching to performance over the default will maximize this. To do this, install indicator-cpufreq and then use the indicator to select performance: sudo apt-get update sudo apt-get install indicator-cpufreq then, press CTRL + F2, type indicator-cpufreq, and then press ENTER Click ...

If you're new to ubuntu I don't recommend upgrading till the next 16.04 LTS. I had many problems with 14.10, 15.04 is better, but the most stable release is 14.04. The graphics drives aren't that important. With 15.04 you get newer software and better look, so if you wanna upgrade, upgrade to 15.04, as it will get drivers in a couple of months if not ...

My best guess is that your dialog window disappeared outside the view of your screen. I had this occur both under Windows and Linux (especially when using dual monitors). Remove your personal settings and restart Inkscape. Under Ubuntu: just remove this folder: ~/.config/inkscape (the folder inkscape in the hidden folder .config in your home directory). ...

You have a few options: (higher numbers are more difficult) 1/ Go to your BIOS and disable the NVIDIA card entirely. (refer to the operator manual of your machine as all BIOSes are different) 2/ Buy an refrigeration laptop cooler. (basically a mini-fridge for a laptop) 3/ Close the laptop, unplug all power cords and batteries, turn the machine on (yep: ...

Ubuntu comes with some preinstalled open-source graphic drivers (Xorg). They are enough for office and some games, but of course they get far less power out of your graphics hardware than a proprietary driver would do. Its advantage is that it is open-source and pretty stable, while proprietary drivers (e.g. those from nVidia) often cause problems and are ...

That's the black screen issue with nvidia-prime, xorg, wayland and the heavy work on these topics during the last year(s). The most recent cause of that problem is explained herein: Black screen when in nvidia mode after updating to kernel 3.13.0-45 See the answer from Charl Botha, Feb 2 at 22:15 This one is an extremely annoying bug. As a rule of thumb: ...

My best guess would be that this is caused by the discrepancy in VRAM. The first GPU (Radeon HD 6450/7450/8450 / R5 230 OEM) has 1GB of VRAM, while the second GPU (Radeon HD 3450) has only 512MB. When you put together multiple GPUs, the VRAM doesn't add up, it is the same as the GPU with the lowest RAM. Essentially, you're just boosting your processing ...

Yes if you had activated this PPA in your system all packages will receive updates on performing sudo apt-get update && sudo apt-get dist-upgrade or from the GUI update manager. This will however not only upgrade your Nvidia graphics drivers but also upgrade all other packages this ppa provides. Automatic or unattended (security) updates will not ...

install a proprietary driver Since you are gaming this is the first thing you should do. You need to enable non-free sources so: Open Ubuntu Software Center go to Edit -> Software Sources Enable the "Proprietary drivers for devices (restricted)" option. Close the Software center run sudo apt-get update to make sure things are up to date go to your systems ...

The answer still isn't black and white. There are two different drivers (and soon a third that aims to superset both). There is still no clear winner between the two. Here's a snippet from the Arch wiki: The open source driver is currently not on par with the proprietary driver in terms of 3D performance on newer cards or reliable TV-out support. It ...
