I have a Dell Inspiron 531s desktop computer. I have installed Ubuntu 14.04.2 on it, but I can only install it from USB when I go to the "Install Ubuntu" option and not the "Try Ubuntu without installing" option because nothing will show up. When I boot up Ubuntu, I can log in, but after that, there is only the background and my mouse and nothing else. I have tried all kinds of things from other threads, but they have not worked. I have also tried installing nvidia-current and nvidia-current-updates to no avail. None of the commands from the mentioned thread works for me. Also, I can boot into recovery mode, but only if I don't have the Nvidia driver. And I haven't been able to do a normal boot at all.

When I login, nothing happens.   I am presented with my desktop wallpaper.    No Dash, no Launcher, nothing.

I am using the  ppa. I got an update dialogue today which stated that I can update my nvidia driver to 367.18 (~gpu16.04.6). I started the update just like every time, but it failed with  Failed to get unit file state for var-lib-snapd-lib-gl.mount  After rebooting, my graphics driver was broken and I was forced to go into recovery mode.  As usually when my Nvidia driver breaks, I just uninstall it with  sudo apt purge nvidia* to reinstall it clean afterwards.   Doing this in recovery mode uninstalled all except the nvidia-opencl-icd-367 package which failed with the error above.   Trying to manually uninstall this package ends with these errors:       Update @20160605 - Solution:  Following Videonauth's answer below solves the issue. Please go through all the steps and make sure to reboot after removing everything of NVIDIA via sudo apt purge nvidia* succeeded without issues and after reinstalling the driver via sudo apt install nvidia-367.  This shall get your driver working again.   If this does not help, try to manually remove all old xorg configs sudo rm /etc/X11/xorg.conf* &amp;&amp; sudo rm /etc/X11/xorg.conf and reinstall the driver again sudo apt install nvidia-367 --reinstall.  If this still does not let you log back in (Typical error: Logins screen --> password has been entered, enter pressed --> goes back to login screen) try completely removing your Nvidia driver again from by switching into text console from the logscreen with Ctrl+Alt+F1, login with you account name and password, donwload the appropriate driver for your graphics card from  within console, stop lightdm:  sudo service lightdm  Install Nvidia's binary driver using sudo ./NVIDIA-VERSION...  and reboot system:  sudo reboot now  System:  Ubuntu 16.04 64bit  Linux 4.4.0-22

After successfully updating my bios,  and I ended up with a blinking cursor on the top left corner of a black screen. No errors, no nothing. The bios now only listed a SATA: &lt;disc name&gt; boot option in place of the usual UEFI ubuntu one. I'm using a GPT partitioning scheme.  I eventually found that the working solution was to properly reinstall grub-efi-amd64. So, how do I do this ?  PS: Actually, i succeeded to reinstall GRUB2 EFI on my own and will post my answer here as I was unable to find any complete how-to on this.

I recently tried to install Ubuntu Desktop on my laptop, but it wasn't successful, as I had the same problem on every startup.  The Ubuntu version I tried to install is 14.04, and it was downloaded from the official site. I had no clean disk, so I tried to install it from my USB. I went Ubuntu forums and found several ways to write my ubuntu.iso to USB. I had tried a lot of them, but every time I had the next problem: when Ubuntu is only loading, it writes something like No caching mode page found, which is going before Assuming drive cache: write through. After that the Ubuntu logo appears and five white dots under it. For 4 seconds all of them become red, and them nothing happens. The Ubuntu logo is just staying on the screen even after an hour of wating. For all this time the USB indicator is not flashing. I've tried to google this, but I had found nothing.   Then while searching forums, I found a way to install Ubuntu inside Windows (maybe it is important to mention that I have Windows 7 and Windows 8 installed on my laptop). So I mounted my ISO again and started wubi.exe where there was not any button to install it from inside. After several minutes I've got the issue: I typed H:\wubi.exe --force-wubi in my cmd, and it worked. I pressed Install Ubuntu inside Windows, followed the instructions, and reached the end of the installation. After this I really got a possibility to choose Ubuntu as the OS, but even than I get the same problem: nothing happens. But this time I got the message, which says that installation of Ubuntu will continue on Ubuntu booting. I can press the Esc key and choose different ways of its loading, but any of the options leads to the same problem. Except Verbose Mode, where text is first displayed and then the same problem appears.   Ubuntu is installed on the clean logic disk.  How can I fix this and continue the installation?  P.S.: Setting "nomodeset" in F6 menu on booting solved my problem.

I have installed Ubuntu on, but now I am trying to install NVIDIA CUDA Toolkit for the GPU. When I install it, it says that there is no driver found, so I have tried to install the driver, but I don't know why after installation, the system not coming up. Maybe it is because of the wrong version of the driver.   When I tried to detect the driver version using sudo lshw -C display , it showed this information:    But here it doesn't say that what is the product name of the driver, and also when I go Software &amp; Updates -> Additional Drivers, then it says NVIDIA Corporation: Unknown.    What should I do?

I have an older Nvidia video card and my PC crashes when installing the driver for the video card in Ubuntu 16.04. When I get to the login screen but no further: after entering my password, the system went into a loop and returned always back to the login screen [with funny stripes present].   How do I fix this problem?

The reason I'm asking is that none of the games I've installed through software center that require 3D accelartion like TORCS for instance will run. When I try to run then, nothing happens. I have a Dell Inspiron N5110 with a nVidia GeForce GT 525M.  I tried the following which I were some suggestions for people with similar problems:  lspci -v   Which gave me:  01:00.0 VGA compatible controller: nVidia Corporation Device 0df5 (rev a1) (prog-if 00 [VGA controller])     Subsystem: Dell Device 04ca     Flags: bus master, fast devsel, latency 0, IRQ 16     Memory at f5000000 (32-bit, non-prefetchable) [size=16M]     Memory at e0000000 (64-bit, prefetchable) [size=256M]     Memory at f0000000 (64-bit, prefetchable) [size=32M]     I/O ports at e000 [size=128]     Expansion ROM at f6000000 [disabled] [size=512K]     Capabilities: &lt;access denied&gt;     Kernel driver in use: nvidia     Kernel modules: nvidia_current, nvidia_current_updates, nvidia, nouveau, nvidiafb   I also tried:  egrep -i " connected|card detect|primary dev" /var/log/Xorg.0.log   Which gave me:  [    20.873] (II) intel(0): Output LVDS1 connected   And:  nvidia-smi -a   Which gave:  NVIDIA: could not open the device file /dev/nvidiactl (No such file or directory). Nvidia-smi has failed because it couldn't communicate with NVIDIA driver. Make sure that latest NVIDIA driver is installed and running.   I don't really understand what all this means.

I want to install Ubuntu on my dad's computer. The trouble is his computer will not boot from the live cd. I think the trouble has something to do with the bios. It is an Acer,model number 4520 and currently it has Windows Vista on it. How do you find bios on this computer? Here are some more details about the computer:   120 GB harddrive 64x2 dual core processor up to 384 MB NVIDIA GetForce  Thank you all in advance for your kind and generous support.

I installed Ubuntu 14.04 on my Lenovo IdeaPad Y510P today. Everything worked fine, but after installing my graphics card driver the background became pixelated (Nvidia GeForce GT755m). I downloaded the driver through Additional Drivers and selected Version 331.113 (Proprietary, tested). It was using Nouveau before.  When I apply Nouveau it becomes clean again, but it is much weaker when I open games, it gives me very low FPS even in Counter-Strike. With Nvidia driver FPS and everything else seems fine, except things look pixelated and when I minimize windows and maximize again, the window goes black.    I attempted to solve the problem myself by removing the old Nvidia driver and manually installing the latest version, but it did not help.  Please let me know if you need more details.

I can buy Dell Latitude E7270 through my employer. It will come with Windows, but I would like to install Ubuntu (most likely 14.04). This model does not appear on the list of certified hardware, however. Does anyone know whether I should anticipate any problems with his laptop? Thanks!

I am about to install Ubuntu on my new laptop, but I don't have access to a USB drive of any sort and it doesn't have an optical drive. Would it be possible to boot into the Ubuntu installer if I save it to a new partition on my hard drive and boot from there via the BIOS?  In case you need it, , which lists my system specifications.  Thanks in advance for any assistance you may be able to provide. :)

So i'm trying to install Ubuntu on my laptop, it seems to work fine until it tries to install grub. I haven't seen progress the past hour and this is the second attempt.  I'm trying to install 13.10, using a Linux Live USB. I don't care about the contents of the laptop.   I've been trying to find instructions about installing grub before starting the installation, hoping that would solve my issues, but I came up empty.  Laptop is 2 years old, it used to run dual-boot windows 7 and Ubuntu. I'm now doing a fresh install of just Ubuntu.  I hope anyone knows how I can find out why it is happening.

Recently installed a clean version of Ubuntu 14.10 on my system. Previous to that, I'd been running Windows 7 with no problems.   My system has two screens, one of which is a LG Electronics 24EN43 which is hooked up to a GeForce GTX 650 via HDMI. This is the default screen. The second screen is a DELL 2009W connected to a GeForce 210 via VGA. My problem is that screen 2 does not seem to be behaving properly.   I can move my cursor right to the second screen, and my cursor becomes a black X with a white border. I can then move my cursor back left onto the first screen. I cannot move any windows to the second screen, and I cannot open any programs or terminals on the second screen. The second screen has a black background.   I am currently using the NVIDA X Server Settings utility, and under the 'Additional Drivers' section of Software &amp; Updates, I am using the NVIDIA binary driver - version 331.38 from nvidia331  Here is a haste-bin of my configuration file for the XServers.   Here's some other things I have noticed:   If under the Additional Drivers, I use 'X.Org X server - Nouveau display driver from xserver-xorg-video-noveau (open source). Then the second screen does work, it has Unity, background, and works like it should. However, the cursor on screen 1 has an annoying flicker, the computer will randomly freeze and crash, and it is really bad at watching videos (you see bars going down the video as it slowly refreshes at 0.5 frames per second)   If any additional information is required, I am happy to provide it. Many thanks

The NVIDIA graphics driver on this PC is several versions out of date, so I went to upgrade it due to an unrelated issue. I went to the NVIDIA website, downloaded the 64-bit Windows 10 driver for the GT 720 GPU. I ran the installation as you normally would only to be met with the error "NVIDIA Installer Failed", and it told me the "Graphics Driver" failed to install.   Now I only have one usable monitor, the other is not detected, yet it turns on briefly as Windows initially loads the desktop.  What I Have Tried  Clean Installation  This is the first thing I tried, I restarted the computer, waited a while, and then I ran the NVIDIA driver installer, I selected "Custom Install", and then I ticked the "Clean Install" checkbox. This failed in the same way as before. Note, I also tried "Run[ning the updater] As Administrator".  Windows Update  I opened Windows Update to check for updates, since this can often fix failed driver installs. It said there was a NVIDIA driver update available, so began the update process. This failed with the error "0x80070003". I tried again, it failed again.  Manual Driver Install  From device manager, I right clicked on the GPU, and clicked "Update Driver Software", I opted to browse for driver files, with "Check subfolders" checked, and navigated to C:\NVIDIA\DisplayDriver\368.39\ and clicked "OK". This failed with "Code 28".  Manual Driver Install (Automatic)  Same as before, except I let Windows find the driver online automatically, I presume it found the same files I had already downloaded, and downloaded them again. This failed.  I am still stuck with one working monitor, reduced graphical performance, and am unable to install the NVIDIA driver.  This is my work PC, so I don't have a huge amount of time to reinstall Windows, so I'd rather not do that, as I have various customisations in place, and lots of programs installed. It'd take a long time for me to do all of that again.    EDIT: More Info  There are no NVIDIA listings under "Uninstall a Program" in the Control Panel. Yet the "NVIDIA Control Panel" app is still in the start menu, but does not start. I believe that is because there are just three DLL files in C:\Program Files (x86)\NVIDIA Corporation\coprocmanager, and no other files/directories in coprocmanager's parent directory.  When the driver is installing, my second monitor starts working, and then stops when the installation fails.  When the driver is installing, it briefly appears as "NVIDIA GeForce GT 720" in Device manager, after it fails, it goes back to being labeled, quite simply, "Display".  Tried running...  PsExec.exe -i -s "C:\NVIDIA\DisplayDriver\368.39\Win10_64\International\setup.exe"   ..to no avail.  PC Specs (from Speccy):   Custom build NVIDIA GeForce GT720 (not from Speccy, since it just lists the monitor under Graphics).

I can install Ubuntu 13.10 in parallels ok and then log in.  Problem is Ubuntu does an update and I get black screen / desktop such that I can't see any app windows that I open.  I've tried a few of the other suggestions and they don't work for me.

Today I tried several times to install Ubuntu but I have some GPU problems.  I have a bootable stick. When I boot in UEFI mode all its normal but the installer isn't able to install the boot loader.  When I boot in leagacy mode I'm able to install Ubuntu but only when I unplug my GPU GTX 1070.  When I don't do that, I get an this initialization error from the installer:  3.021954] nouveau 0000:01:00.0: unknown chipset (134000a1)   I installed Ubuntu normally without the GPU. I installed the drivers, rebooted, shut down, pluggeed in the GPU and tried to boot but it got stuck at:  /dev/mapper/isw_bdifbbjbai_Raid0p3: clean, 191449/8855552 files, 1677252/34500448 blocks   What should I do? When I unplug the GPU I can boot easily, but I need my GPU! :D  My PC has a GTX 1070 GPU, i7 4790K CPU, and two hard drives:   250 GB M.2 SSD, which contains Windows 10 and its boot loader. 2 TB RAID-0 WD, with 1,85 TB for Windows 10 files and 150GB where I installed Ubuntu and its boot loader.
