After searching I found the answer in launchpad. This is an issue with xorg.conf file actually. One can generate the xorg.conf file by using the command sudo aticonfig --initial if one is having the AMD driver. Else one may try sudo nvidia-xconfig if one has nvidia graphic driver. Then one needs to open the xorg.conf file by running the below ...

As you get the following error: Error: alternatives are not set up properly You may try to set the alternatives yourself. When I switch to Intel I see: update-alternatives: using /usr/lib/nvidia-331-prime/ld.so.conf to provide /etc/ld.so.conf.d/x86_64-linux-gnu_GL.conf (x86_64-linux-gnu_gl_conf) in manual mode update-alternatives: using ...

This is a bug (LP #1214508). You can switch using: sudo prime-select intel sudo prime-select nvidia Also, Bumblebee is still supported so you can install it if you prefer. You'll have to remove nvidia-prime then as you can't use both.

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 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.

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 ...

I didn't see any errors in the Xorg.0.log file the radeon driver seems to work well so try to create a Modeline for the unsupported resolution. Open a terminal with Ctrl+Alt+t and type: cvt 1366 768 It should return: # 1368x768 59.88 Hz (CVT) hsync: 47.79 kHz; pclk: 85.25 MHz Modeline "1368x768_60.00" 85.25 1368 1440 1576 1784 768 771 781 798 -hsync ...

If you can access a terminal use sudo poweroff. You can access a TTY by pressing Ctrl+Alt+F1; TTY is just a terminal. You can return to the graphical desktop by pressing Ctrl+Alt+F7. Otherwise you can use kernel interupts to safely shutdown the computer: Ctrl+Alt+Print Screen+R,E,I,S,U,B (Hold down Ctrl, Alt, and Prnt Scrn then press REISUB in that order ...

The root of the problem described above is probably a lightdm bug: https://bugs.launchpad.net/ubuntu/+source/unity-greeter/+bug/1292467. I had this problem on an Atom Mini-ITX motherboard with Intel NM10 graphics which includes an internal LVDS display port. The Boot with "video=LVDS-1:d" workaround solved it for me. Instructions for making the boot option ...

There are a few GUI tools available to control and monitor AMD open-source graphics under Linux but none of them are as easy to use or install as AMD's CCC: DriConf - GUI for controlling the direct rendering settings (OpenGL) of all open-source drivers. Pretty hard to use and hasn't been updated since 2006. Phoronix has an overview and comparison to AMD's ...

The backend is different: Compiz uses a 3D compositor to display the windows. Whereas Metacity displays the windows in 2D. So if you have a low end graphics card and/or want to save energy on a mobile device I would suggest that you use metacity. There also used to be problems with 3D applications in combination with compiz.

This may be the cause of your problems: Nvidia-Prime Freeze Theese two things have worked for me so far; either: Disable touchpad in: System settings -> Mouse & Touchpad -> "off" and use a regular USB mouse. Install nvidia-prime sudo apt-get install nvidia-prime, find "Nvidia Settings" in dash, and under "Prime Profiles" choose "Intel(Power saving ...

Your xorg.conf has two device sections: Section "Device" Identifier "aticonfig-Device[0]-0" Driver "fglrx" BusID "PCI:1:0:0" EndSection Section "Device" Identifier "intel" Driver "intel" Option "AccelMethod" "uxa" EndSection This is causing your machine to attempt to load both the fglrx and the intel ...

UPDATE As of Jan 30, 2014, the bug seems to be fixed. With the latest drivers from oibaf's PPA, there are no graphic glitches in Chrome. Are you using oibaf's ppa with latest graphics drivers? Looks like there's a bug introduced in recent Mesa builds: Bug 73978 - Intel driver breaks hardware accelerated flash on Chrome (supposedly related to Flash ...

They're not necessarily. They spec-ed out frame rates on a more minimal linux (Ubuntu without Unity to take weight off the video card) and Left4Dead2 had BETTER frame rates on linux. It's my understanding TF2 runs on the same engine, so in theory if you were running something like XFCE instead of Unity it would have better frame rates on the same ...

Available graphics drivers won't be appear on the additional drivers tab if you fail to add the below to your System. sudo add-apt-repository ppa:xorg-edgers/ppa sudo apt-get update Now go to Software and Updates and select additional drivers tab. You will see the available options.

you can use glxinfo to test if your X server is using the GPU driver. glxinfo queries X server about its OpenGL version, renderer string, Visuals supported and other infomation. glxinfo | less

No, a GPU is not necessary for Ubuntu to run on the system. However, if you don't have a serial console or some other management interface with which to visually see what you are doing on the system, you may find it difficult to work through the installation process.

Go see for yourself. Download an Ubuntu Desktop ISO, create a bootable USB stick or burn a DVD, boot it up and select "Try Ubuntu". This will not alter your hard drive or install anything, Ubuntu will be run from the installation medium. If you like it, just click on the "install" icon on your desktop.

Install the driver package using the command: sudo apt-get install xserver-xorg-video-radeon If it is already installed, then purge and reinstall: sudo apt-get --purge autoremove xserver-xorg-video-radeon \ && sudo apt-get install xserver-xorg-video-radeon You might need to reboot your system for the changes to take effect. (You can reboot ...

A while back, Spotify enabled hardware acceleration by default in the desktop client. On certain systems (not only Linux), incompatibility with the graphics drivers causes some content to fail to render. The suggested solution is to disable hardware acceleration in the clients' Preferences (Edit > Preferences): Applying this change requires a restart of ...

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 ...

So it wasn't a multiple graphics card issue either. Another thing you can do is try another kernel and / or try to install the lastest drivers. Intel provides deb packages for Ubuntu 14.04 here. Discarded information left for documentation There's an issue with the i915 driver in kernels 3.15 and 3.16, to check if you hit this bug, post the output of grep ...

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 ...

What do you mean? The nVidia card is right there.
