After much searching I've got this fixed. For anyone else stuck here was the solution sudo apt-get purge nvidia* sudo add-apt-repository ppa:bumblebee/stable sudo apt-get update sudo apt-get install bumblebee bumblebee-nvidia good luck out there!

I ended up downloading the newest drivers straight from NVIDIA from here and installing them manually. Obviously, this won't automatically update in the future (AFAIK). The path I had to take was actually quite convoluted, involving adding the nomodeset flag to GRUB, then killing lightdm, and then running the installer. I followed some suggestions from here ...

I have found the problem, for anyone that's stucked like I was for now, and have the same output for xrandr, here's the solution: xrandr --newmode $(cvt 1280 1024 60 | grep Mode | sed -e 's/.*"/1280x1024/') xrandr --addmode DVI-1 1280x1024 After that you can change the resolution by going to display

Does the Display / Screen / Monitors settings page (whatever it's called in your DE) have any options to change resolution, & do they work? And according to xrandr there you should have 4 resolutions available, have you tried changing it with xrandr, maybe with xrandr -s 800x600 or whichever you want, with/without -r 60? For a different mode, not ...

These lines from your dmesg look suspicious, if I see a --[ cut here ]-- in a log it's usually something important, as is the distinctive-looking call trace that follows: [ 42.752749] ------------[ cut here ]------------ [ 42.752792] WARNING: CPU: 0 PID: 493 at /build/buildd/linux-3.16.0/net/wireless/sme.c:791 cfg80211_roamed+0x91/0xa0 [cfg80211]() ...

The xorg-edgers are known for potentially breaking systems. You will need to boot into one of the recover modes (the one with networking available) and remove that package: sudo apt-get install ppa-purge sudo ppa-purge xorg-edgers sudo apt-get update sudo apt-get upgrade To get into the recovery mode, hold the left shift key down at boot time so that you ...

Don't go to the NVidia site to download their driver, as you'll never get rid of it in the future. The standard Ubuntu NVidia drivers generate some problems on slightly older and slightly newer NVidia hardware. If you want more then the standard Ubuntu repository drivers, install the xorg.edgers PPA. As the xorg.edgers group ask not to give installation ...

Same problem here - an update came for 'nvidia-current' drivers yesterday, I updated and on reboot - no display, out of memory messages and crashing, etc. I am running MacBook Pro (late model) in dual boot set up with 14.04. One solution that I found to quickly get back and recover is to: somehow get to the shell (for me the Cntr+ Alt + F1 never worked on ...

This sounds like a video drive issue. Are you connecting the displays to the onboard Intel video controller or the NVIDIA controller? If you are using the NVIDIA controller, I'd recommend going to the NVIDIA site, looking up the NVS5200M video controller, downloading the driver for Linux, and then reload the driver and reboot the system.

I use KDE, so my /etc/lightdm/lightdm.conf is: [SeatDefaults] user-session=kde-plasma greeter-session=lightdm-kde-greeter The reason a lot of you are seeing failures to open ".desktop" is because the upgrade leaves lightdm.conf set with "greeter-session=", which means the greeter name is "". Lightdm adds ".desktop" to whatever greeter-session is set to, ...

To me, it appears that gdm starts too early. The following consistently seems to help: Switch to a console via combination Ctrl+Alt+F1 Login Issue the command sudo service gdm restart If necessary, switch back to the graphical user interface via combination Ctrl+Alt+F1 The list of users appears. It's strange that this issue appeared only after some time ...

Mostly it can be solved by: Type password into login screen, hit enter - nothing happens (removing the files like in the second option helped me a couple of times)

Scenario like, your Ubuntu GDM(Display Manager) got corrupted due to sudden power failure & it can't be restarted so. Do one thing read this OR this. This links have good question answered correctly here on this site only. Hope it'll help you out.

Like I was saying, it shouldn't have been doing that in the first place. Install the package linux-image-extra-(yourversionhere) -- it's got the i915 and radeon drivers, which you should need one of. Ya, libreoffice and firefox use quite a few threads, not to mention a fair amount of graphics processing. Now if your system can speak to the gpu in the ...

Since we indicated through the comments that the NVIDIA Drivers are not installed try to reinstall the nvidia drivers by following the the linked doc under section Installation without X / from the console https://help.ubuntu.com/community/BinaryDriverHowto/Nvidia sudo apt-get install --reinstall nvidia-331 did the trick. (Check Edit 2)

Both Inkscape, and ImageMagick from the repositories depend on X11. You therefore won't be able to install them from there without also installing X11 as a dependency. ImageMagick can amongst other options also be compiled without X11 dependency for manual installation.

According to the wiki Inkscape depends on GTK, which could depend on X11, but I am not sure. You could try running the following command to simulate installing it: sudo apt-get install -s inkscape See if it would pull down some X11 packages.

I've found what was causing the problem. udev had some weird problems because of kernel misconfiguration. File systems -> Inotify support for userspace (whatever it is) option needs to be checked. After kernel recompilation everything started to work.

Sounds like something was wrong the whole time, and now some change has occurred to keep it from eventually "righting" itself. Since your virtual terminals still work, the problem has to do with your desktop. Are you using appropriate video drivers? Which word processor and web browser apps do you use? Which version of Ubuntu? Also, do your hardware ...

I tried the xinput-redirection trick, changing the center mouse "button" (actually a wheel) so it acts just like the left mouse button. It still works as a wheel, and has (apparently) stopped pasting things into random places in the middle of my source code as I scroll past. In my case the command was xinput set-button-map "PixArt USB Optical Mouse" 1 1 3 ...

In my case, adding this line to "Device" Section of the xorg.conf file solved the problem. Option "ModeValidation" "NoMaxPClkCheck" As seen in this Question.

Use SSH. If you can access the machine over vnc I guess you could login over SSH too. If you never did this befor here is, how to: First check if openssh-server daemon is running: ps -A | grep sshd You should see sshd listed. If not, continue here: install openssh-server If your system has the default ssh configuration for ububntu, you should be abled ...

Sure just install a ssh server. You should also probably route the vnc over the ssh but i am not gonna focus on that. The ssh server does basically what the vnc does but for tty (not for the gui). It is capable of many things but is mostly use as a way to display a terminal window to a remote computer so you can use commands from the remote computer. You ...

There is a sample of LightDM setup for multiseat using Xephyr. It looks like Andrzej Pietrasiewicz (the author of the blog copied/referenced below) created a PPA with all the code displayed below. By installing that PPA, you should be able to get a lightdm installation to work "magically". Note: As I have been trying to get that to work, I have not ...

I spent too much time with exactly the same issue: X loads correct settings, then, when I log in, settings are overwritten. As I am on a fully encrypted single user machine (and therefore don't care about login), my option was to install nodm which replaces lightdm or other display managers. It has to be enabled and configured in /etc/default/nodm to ...

This is a partial answer. My problem was solved, but I did not fully understand why/how. I answer my own question, hoping this may shed some light for others having similar issues, but they should make sure they can undo everything they try, as I cannot guarantee that this works for them Boot choosing Linux Recovery mode (here the graphics will still look ...

How have you installed VirtualBox? On the virtualisation host you only need to install the package virtualbox and you should be ok. Don't forget to check documentation in /usr/share/doc/virtualbox.

Since you have a dual GPU you should use Nvidia-prime or bumblebee to manage them both. Bumblebee allows you to switch between GPUs at a cost of performance Nvidia-Prime allows you to choose what GPU should he use. you should try both to see if its fixed i would advice nvida prime first to force it using your nvidia.

What i did (on 14.04) after pulling my hair out over this (Google shows a LOT of hits about older versions of Ubuntu, but nothing about newer ones) was ignore the Xorg.conf stuff altogether. Instead, i enabled automatic logon, and put the following in my .xprofile: xrandr --fb 1920x1080 xrandr --newmode "1920x1080_59.9" 138.5 1920 1968 2000 2080 1080 1083 ...

Same here on a Siemens laptop: without NVidia driver, no HDMI. I circumvented the NVidia driver problem by adding "bleeding edge" drivers (not yet released to the general public) If that's the route you want to take too, just add the PPA of xorg-edgers (you can roll back to previous drivers if the latest (but not always greatest) doesn't work)

The version, conflicts and dependencies are included in the .deb package, more precisely in package-root/DEBIAN/control. Did you adapt these? DPKG doesn't determine the package version by the name, but by the version specified in the control file.

Please use the fully updated current version of Ubuntu. There is no need to separate install of any kernel headers or any other packages, up-to date current Ubuntu is absolutely enough to install VirtualBox additions (I did it few times recently).

As opposed to other answers to this question, the very PPA states that it should be used as a whole and NOT via individual packages (i.e. not pick individual updates, but install all of them). == Important notice == This PPA is currently meant to be used as a whole.
