You can not kill or skip nouveau because it is part an integral part of linux kernel, part a module of X server. It goes in separate package but removing it is a really bad idea. You can blacklist nouveau module but this will likely lead to your GUI not booting at all. You should ask a new question with proper details on the problem, the community will solve ...

A workaround is to disable hardware acceleration using --disable-gpu.

Solved - the issue was the same as this one on the Firefox Forums. That can be caused by a problem with the color profile for your display monitor or color profiles embedded in images. You can disable color management to test that. You can set the pref gfx.color_management.mode to 0 on the about:config page to disable Color Management. You ...

You're not going to upgrade the graphic card of a laptop, unless you find a motherboard with the graphic card you need that fits the case. This may happen only between products of the same vendor and of the same product line, because usually laptops motherboard are custom built for the specific product / product line. So you should look at motherboards (not ...

I managed to fix the problem by simply removing all the proprietary drivers and left the default generic one. Since I use my laptop just for working purposes it works like a charm.

Standard Ubuntu is for new hardware (I doubt you'd be dismantling to scrap a perfectly good sandy-ivy bridge or haswell mobo). For older boxes with limited resources, it is advised you use a "flavor" of Ubuntu that is optimized to run on limited resources, such as: Xubuntu or Lubuntu and even UbuntuStudio runs well on older pentium-4 processors.

Try running "sudo ubuntu-drivers devices". With older versions you need jockey-text. "sudo jockey-text -e xorg:nvidia_current"

You could try upgrading to the latest: sudo add-apt-repository ppa:xorg-edgers/ppa -y sudo apt-get update sudo apt-get install nvidia-current If this doesn't work can you send us the results of lspci -v | grep VGA so we know what card you have. Also what version of Ubuntu are you running?

I'm using 14.04, and I've had similar glitches, though not this particular one. Perhaps it has to do with Unity. I would try: Save your work Close Inkscape Reopen Inkscape Export Bitmap If you still don't have success, you can try the command line to export, which is fairly straightforward (it just means you need to know what your parameters are and type ...

While there is no way of not having graphics card problems, you can choose the newest, stable driver that can help. NVIDIA is listing version 349.16 as the newest driver, so that is the one that I would choose. After choosing that driver, use the nvidia-settings as a elevated user to configure higher settings. From a terminal window type in sudo ...

AMD has dropped support for the Radeon HD 4000 series, which is what you have. You might still be able to use this driver, but it probably won't be an update for what you have.

I researched my error further and found that it was caused by low disk space. (I was somehow at 100% use and 0 bytes free). I was able to enter the console and delete some files and then everything was working as normal.

If you do not wish to use bumblebee on your computer and you're alright with logging out and logging in again every time you want to switch GPUs, then you should install nvidia-prime: sudo apt-get install nvidia-prime nvidia-331-updates sudo reboot now sudo prime-select nvidia This will start the desktop using the NVIDIA GPU. Otherwise, if you want to ...

The original poster solved the problem and reported the solution in an edit: In fact, it was not a graphic card problem. I had to disconnect the dvd drive and connect it to another free sata connector (I don't really understand why Ubuntu had trouble with this connector and Windows 7 not). After that, everything worked fine.

If you have nvidia prime installed just go to nvidia x server settings and choose it in prime profile (you need to relog to apply the changes). To install prime: First make sure bumblebee not installed! Or just remove it: sudo apt-get purge bumblebee* Install: sudo apt-get install nvidia-prime You can also install prime-indicator for easier ...

Don't worry about the lspci part. It's just because your /usr/share/misc/pci.ids* files are not up to date. Just run "update-pciids" as root.

You very probably also have an Intel card on-board and these are Intel upgrades (which xorg-edgers provides too) I've applied them as I'm running Hybrid Intel-NVidia and had no ill effects, but as you're running on nVidia drivers only, these drivers are only being installed because they're there already! That being said: take a system backup first (you've ...

I'm glad you fixed it, but people should know there's an easier way. I had to use it repeatedly when I was trying to use the Unity desktop.

Two things may be wrong. With the second possibility usually you don't make it to the login screen, so I kind of doubt that's it, but a corrupt install remains a possibility. This sort of sounds like a common Unity malfunction. The forums are full of Ubuntu 14.04 users trying, usually in vain, to make Unity work. If it'll let you, and it sounds like ...

Posting as an answer instead of commenting. I've installed Win7 Pro x64 as I purchased it a while back and the machine didn't detect it, at all.

Unfortunatelly you should turn off 3d acceleration. Don't know why, but just do it. It's solved same problem with my installation.

You might try downloading the linux drivers for your graphics card. You can find them here.

Open System Settings and click Details. The graphics card you're currently using for Unity and (probably) all your applications should be shown besides "Graphics". However, if you want to know which card(s) are powered on, you can run: sudo cat /sys/kernel/debug/vgaswitcheroo/switch It should show something like this: 0:DIS: :Off:0000:01:00.0 ...

Thanks all for your support. Luke put me on a track that solved the problem in a easy way.

Solution: I solved it (meaning I haven't had the Low Graphics Error now for about 10 reboots) by installing drivers for my GPU (2x 280X AMD cross-fire). I've done this previously with no success, but I guess I then had tried some other things before installing the drivers that messed it up. To help others with the same problem I'll explain what I did in ...

I've found that if you enable the "FXAA" setting in the NVIDIA X server settings, fonts in Ubuntu look terrible, especially in Chrome. Disabling OpenGL in Compiz also fixes it, but then Unity won't load. After chasing the issue for some time, I finally figured out that it was the FXAA setting. Yes, I've tested it numerous times and it is definitely that ...

That's why you're supposed to use the driver which are distrubuted through Ubuntu repositories. When you download driver from Nvidia site, it will modify kernel.
