Excellent question. Workloads The /usr/share/xdiagnose/workloads directory has a set of workloads designed to exercise your graphics system to trigger lockups. $ ls /usr/share/xdiagnose/workloads/ README do_monitor_rotation_loop do_chws_loop* do_screensaver_loop* do_cpu_spin_loop do_video_loop* ...

TL;DR: Unless you have tried everything below and now you get a black screen hitting this particular fixed bug, your problem should be solved by now. If you now get: ERROR:gpu_video_decode_accelerator.cc(208)] Not implemented reached in void content::GpuVideoDecodeAccelerator::Initialize(media::VideoCodecProfile, IPC::Message\*) HW video decode acceleration ...

For Nvidia GPUs there is a tool nvidia-smi that can show memory usage, GPU utilization and temperature of GPU. For Intel GPU's you can use the intel-gpu-tools. AMD has two options, fglrx (closed source drivers) aticonfig --odgc --odgt And for mesa (open source drivers), you can use RadeonTop . Source:GPU usage monitoring

It's an interesting idea and I can't see why it wouldn't work on a technical level because Linux does support ExpressCard devices (as PCIE) so the riser on the other end should work and it should detect the graphics card too. From there it's just a case of using the nvidia drivers. However there are some things that might give you grief: You might need to ...

No, all current Nvidia Geforce cards only support two monitors. Even in Windows. For three monitors you either need two cards or a different brand that will support all three at once (ATI/AMD have some that do lots of screens but I'm not sure how well supported this is in Linux). Edit: If you're determined to stick with one Nvidia card, you can get a ...

Ubuntu comes with vgaswitcheroo since 10.10. Therefore you can although it is far away from working as smooth as on Windows. Yet it's enough to turn off either one of the cards and/or switch to using the other ones. You find more information on this topic on help.ubuntu and this linux.blogspot. Since you are fairly new to Ubuntu, I'll tell you the ...

Its because your GPU (or the driver being )is not supported for WebGL. Its browser blacklisted. However you can force enable your GPU for WebGL. Warning: Do this at your own risk. It can harm your hardware. There are usually good reasons (like some critical driver bug) why features are blocked. To launch chrome ignoring the black list, run following ...

You can get the reading using aticonfig --odgt.

That is normal for radeons -- they run hot. It speeds its own fan up when it runs hard to stay about that temperature.

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.

Unfortunately the correct answer doesn't solve your problem. Currently X.org is not able to split graphics to two different video cards. A long time ago there used to be a way to do this using Xinerama, however only the proprietary drivers still support Xinerama. IOW, you can't do this if one of the GPUs is Intel Graphics. Now, you can get this to work ...

There will be no benefit unless you have an application that is capable of using multiple GPU's. Some possible ways to use multiple GPUs: Running displays on multiple monitors Running a game that is capable of using multiple GPUs Running an application such as folding@home or BitCoin mining on each GPU

Enable the driver using "Additional Drivers" GUI: The Nvidia driver included in the Ubuntu repositories (version 295.33) should support your graphics card according to Nvidia (see picture below). You may enable the card using "Additional Drivers", also known as jockey, by hitting Alt+ F2 typing gksudo jockey-gtk, entering your password when prompted and ...

The Wikipedia page shows that your GPU supports upto shader model 2.0. So I think you won't get the shader model 3.0 support with this hardware anyway.

This is the way I've finaly done it on Ubuntu Server 11.04 Install a minimal X11 environment: aptitude install xserver-xorg xserver-xorg-core xserver-xorg-input-evdev xserver-xorg-video-ati lightdm unity-greeter openbox Then, edit /etc/lightdm/lightdm.conf and add the following (replacing YOUR_USER_NAME with the user you will be running hashcat as): ...

I can confirm that it works in 12.04. Tested with PE4H + EC2C on a thinkpad x220, using an Nvidia GTX 560ti. The tricky part was getting a working xorg.conf. I needed the nvidia drivers : sudo apt-get install nvidia-current You need to find the correct pci bus for the graphic card. lspci gave me : 05:00.0 VGA compatible controller: NVIDIA Corporation ...

Yeah! I figured out how to get the hardware acceleration of the Intel graphic hd 3000 to enable unity 3d and gnome-shell. It seems that ubuntu tries to install drivers for both intel hd 3000 and nvidia-optimus card. result? a mess. X11 server can't decide what driver to use and revert to VESA. So the solution is really simple: apt-get remove --purge ...

According to previous posts here, a known bug in the Linux kernel is leading to overheating issues: Heat issues on 11.10 beta? Recent releases (11.04 also) have had a similar problem. A workaround for the Linux 3.0 kernel has been suggested: http://www.techytalk.info/linux-kernel-2-6-38-2-6-39-power-regression-workaround/ I've heard that these issues ...

I have a temp fix for this issue. It was getting so bad that the system was almost of no use with a failure every few minutes and complete hang every hour or so. Looking in /var/log/Xorg.0.log I found that the existing driver was using UXA: [ 12.905] (II) UXA(0): Driver registered support for the following operations: [ 12.905] (II) solid [ 12.905] ...

Yes, absolutely you can make it work with a full install. To make the change permanent in your installed Ubuntu you will need to edit the grub configuration file and add the nomodeset option so that it loads each time Ubuntu boots. It's more complicated to set it to install this way automatically, and it's probably not normally desirable to do so. If you ...

This is probably related to the implementation of Adobe Flash (in Ubuntu, or even in general); while the video codecs used by youtube are standardized, how they are implemented is up to Adobe and it may well be a poor implementation and/or one that uses the GPU excessively. Compared to that, most Linux/Ubuntu video apps use the FFmpeg/libavcodec open-source ...

I am assuming 12.10 and not 12.1. This release is still not stable, and the GPU problem in 12.10 have been bugging every other user since the release. Try popping into IRC channel #ubuntu, every other user is complaining about the same problem. I have an ATI Readon GPU that is causing the same problem with ATI drivers but reverting back to the X drivers I ...

SOLVED: Install Wine 5.9 to fix this issue.

This seems to happen to me on the identical machine when booting in UEFI mode. A temporary workaround is to replace grub-efi with grub-pc and use refit or refind to boot. Of course, that is subideal, as the boot process takes much longer. I suspect that this needs to be fixed in the i915 kernel code.

Ubuntu just has a different fan control than Windows. Seems its profile makes the fans go on a little later than in Windows. This would propably mean that your laptop is more silent :-) You don't have to worry about it because those temperatures are still harmless. Everything under 80°C is fine and even temperatures up to 90 or 100 are OK if this only ...

To get the graphics card model, install mesa-utils .Remember the graphics card model won't be nvidia one. It will be intel, because in nvidia optimus the nvidia card isn't exposed directly. Nvidia card is wired via the intel one --no-install-recommends prevent certain packages from being installed, mainly the nvidia driver. You need to follow the ...

I've recently had the same problem on Ubuntu 12.04LTS. It appears this confirmed regression bug: https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1140716 affecting Sandy Bridge Intel Processors (e.g. my i5-2410M with onboard-graphics). I used the synaptic packager manager to remove the package xserver-xorg-core-lts-quantal and install the package ...

Realizing that I needed to turn the native nvidia drivers off to be able to see the screen; after changing boot sequence, I quickly tapped F6 key to get into the Linux screen. I checked nomodeset to disable the native video controller and hit esc. I was then able to install 12.04 LTS, using linux video drivers. After installing OS, I then installed ...
