This issue occurs because the VNC session you are using is unable to load the currently selected display manager. You can resolve this by changing your xstartup file to use an alternative display manager which does not require graphics acceleration. There are instructions on how to configure this available Here

You did not write this anywhere it your post, but taggs say that you have an Nvidia graphics adapter. You can reinstall the driver from recovery console. Boot using the last kernel in recovery mode. Then choose "root" from that menu. Then run: mount -o remount,rw / apt-get purge nvidia* apt-get install nvidia-331 reboot The system will reboot, and let's ...

I've had the same issue. Installed on multi monitors but disconnecting them after install and reconnecting them so they were redetected fixed the issue. I now have the issue again on install after messing up my earlier success by trying to update to 15.04. Back at the installer again. All is blurry. But changed monitors from a Benq which wants to run ...

Actually I've solved it - the proprietary driver was installed. What was screwing it up was that I had a second monitor of a different resolution plugged into an hdmi port on the same card. I disconnected the second monitor, rebooted and got a proper display. Reconnected the second monitor and let Ubuntu detect it normally and all is now well

You need to install a proprietary Nvidia driver. The best solution for this card is to do it this way. Run in terminal: sudo add-apt-repository ppa:xorg-edgers/ppa sudo apt-get update sudo apt-get install nvidia-346 sudo add-apt-repository -r ppa:xorg-edgers/ppa Then reboot.

For anyone out there who still is in this situation, I upgraded to Ubuntu 15.04 and it looks lots better. I still haven't set up full prime support, but I do have 1600x900 resolution again (couldn't get more than 1024x768 with 14.04 or 14.10.). --kevin

This does not mean that video driver is missing. Otherwise you would not be able to use your system in GUI mode. If you run sudo apt-get install mesa-utils you will see more details on your graphics adapter. But it won't improve anything in your system

It's good that you can still get into the console, as you'll likely be able to fix your problem from there. I'd first look in the logs of your X server and examine what is going on. You can do this with: cat /var/log/Xorg.0.log This will likely give you some message with an (EE) marker, which would tell you were the problem lies. It could be that the ...

Depending on how you installed the fglrx drivers sudo sh /usr/share/ati/fglrx-uninstall.sh or sudo apt-get remove --purge fglrx fglrx_* fglrx-amdcccle* fglrx-dev* Even though this is not directly Ubuntu related, the solution is probably the same on any linux distro (in the first case) and on any debian based linux distro (in the second case).

If you have an Nvidia or AMD graphics card, or a laptop with Optimus or switchable/hybrid graphics, the issue may be the fact that it is does not have the proprietary drivers installed. If this matches your setup, check This out. Specifically, the section "Black/purple screen after you boot Ubuntu for the first time" The answer is to boot (only need to ...

This solution seems to have partially fixed it for me UBUNTU 14.04 Gui text and pictures displaying problem like a virus But instead of the following : Section "Device" Identifier "Intel Graphics" Driver "intel" Option "AccelMethod" "uxa" EndSection I have set the AccelMethod to "sna" Indeed, UXA was giving me terrible lag

This looks like a bug in Intel graphics drivers. There is no vivid HWE for trusty yet. So you can do one of these: Wait till new HWE appears in Ubuntu repositories. It is a matter of a week or two, then upgrade to it. I prefer this. Install Ubuntu 15.04. Do 2 + Intel graphics installer. (I do not like this)

All Nvidia cards have drivers for Ubuntu. And there are lots of Nvidia cards with DVI and VGA outputs. You can buy any of those.

Generally the open source video driver works well for most applications that are not using the video card a lot, but there is also the proprietary NVidia driver you can install through Software and Updates -> Additional Drivers and unless the card you choose is very recent (in which case it could be unstable without updates) there should be no problem at ...

First off Yes, your graphics card, could possibly be using a wrong or corrupted driver that makes it render some GUI elements incorrectly. It's recommended that you reinstall the drivers. You should have begun the post with your specs, but never mind. I guess you're using a Nvidia card. Uninstalling The first thing you need to do is to uninstall the ...

Open System Settings. Click on Software & Updates. Click on the additional drivers tab. You should then be able to select another graphics card driver and click Apply Changes.

Using mesa this should work, but i do recommend to upgrade to the latest ubuntu release or use the updated oibaf drivers PPA and probably also update the kernel using the latest from here, but both mesa and the kernel have improved a lot in the last few years for the 3D support and fixed many problems Finally check this for the direct usage of each GPU

You can follow the official Ubuntu how-to guide. In short - open your terminal and type: sudo apt-get install fglrx Then generate a fresh xorg.conf, before you reboot: sudo amdconfig --initial Reboot. It is a good idea to read the whole article that I have linked to you. There you can find examples how you can backup you current settings and restore ...

Since I cannot comment on the post of Rafal directly. I thought i might just add here that pae seems to be supported now. I am running 12.04 32bit Ubuntu on my EeePc. If you have problems with the system randomly freezing try an older kernel than the highest 3.2.0-82. For my Asus Eee PC R011CX 3.2.0-38-generic-pae seems to be the most stable. It has ok ...

You need to install a proprietary video driver to extend features of your graphical card. You can do it by running sudo apt-get install fglrx And reboot. Due to a bug in fglrx-installer package the driver may not install. To fix it now you can go to System Settings -> Software & Updates -> Updates and click on proposed repository. Then do sudo ...

The best way is to install lubuntu from scratch, but you will need to install applications again. You can install lubuntu desktop by running sudo apt-get install lubuntu-desktop But some Ubuntu services will keep starting and making the system slow. And yes, all applications will work on lubuntu. And terminal commands are same.

I have exactly same laptop. There is a video driver, but it works only with xorg version not higher than 1.12. It means that it won't work on Ubuntu higher than 12.04. The driver works well, but without 3D acceleration. It appeared that it is not possible to make this driver for newer versions of xorg, since the adapter does not support some features. I have ...

The second or third options. fglrx driver is the stable version of AMD's proprietary driver. fglrx-updates driver will be possibly less stable, but will get you driver updates sooner. Either is better than the open source Xorg driver.

Go to the software and updates GUI, look at the Additional Drivers tab, and select the NVIDIA driver for your device You should not have to use 3rd party repositories for this.

To install the drivers for an Nvidia card, you have two choices First the tested stable driver sudo apt-get install nvidia-331 Or the update version sudo apt-get install nvidia-331-updates I recommend the updated version but it may have bugs, you can always just run the first command to change it if you have issues but I never have.

I don't know for sure but I think the list you're seeing in Additional Drivers is not necessarily drivers that you have installed, just drivers that are available for you (which Ubuntu believes would be compatible with your hardware). I think it will install them on demand if you choose one and it's not installed. All those nvidia- packages are in ...

Possible solution to your problem could be Open the System Settings Select Software& Updates From the new Popped-Up window, Select Additional Drivers and hopefully your system will recognize the required drivers. Good Luck!

There are no proprietary drivers for this GPU. Open drivers are already installed. So there is nothing to install.

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). ...

Check that you have installed the package called dkms. After that, when you run the nvidia installer, it will ask you whether you want to register with DKMS. Tell it to do so. Next time when a kernel update happens, it will recompile the shim code automatically. The only thing you need to watch out for are MESA updates. Those tend to clobber the OpenGL ...

You can edit your post to fix your mistake and, by the way, it's fglrx-amdcccle. Now that that's done, yes, it will work fine. fglrx-amdcccle and fglrx-amdcccle-updates are the same package, but the updates one will have more frequent updates. Also, fglrx-amdcccle is only the Catalyst Control Center, not the actual AMD driver. If you want that, you need to ...
