Still using 12.04.x LTS (Because of UEFI RAID 0 addressing sdax rather than MDx issues with 14.04,x LTS) Was experiencing similar problems after a fresh start/'cold' hard boot until an update two weeks ago which seemed to fix the random 'Kernel failed to load.' But apparently traded that off for another set of issues. Now having to Restart the system FOUR ...

I had also the same problem like you guys (Ubuntu 14.04). The problem was indeed into enabling desktop icons like @darent said. I just enabled desktop icons by running: gsettings set org.gnome.desktop.background show-desktop-icons true and desktop with: background wallpaper, context menu under the left mouse button, and all icons came to normal.

There is no direct support for nVidia optimus for linux. nVidia Optimus dynamically switches between the integrated GPU and discreet GPU inorder to improve battery life. However there could be work around, check this link How to set up nVidia Optimus/Bumblebee in 14.04

The standard way would be to copy the /usr/share/X11/xorg.conf.d/50-synaptics.conf into /etc/X11/xorg.conf.d and calling it for example 51-mysinaptics.conf (so that it will be read after the standard one) --- then read it and edit accordingly. In my version, around the start, there is: Section "InputClass" Identifier "touchpad catchall" ...

That post on Ubuntu Forums is over 4 years old - newer drivers have been released since then. For Radeon drivers, this is my method. Boot up and when the black screen appears, press some of the cursor keys and a box appears with an X server error. Press CTRL + ALT + F1 to get a tty terminal. Log in as root. The password is your own password that you set ...

I purged all the Nvidia drivers and resorted to using the OS Nouveau drivers as a temporary fix. The previous releases of the Nvidia drivers did not help. Thus it appears to be a bug in the official Nvidia drivers as the Nouveau drivers resolve the above issues. However, Nouveau also introduces other problems since they are just a reverse engineer of the ...

First, it sounds like you've made some valiant attempts to correct the problem. Kudos. Perhaps try the command: dconf reset -f /org/gnome/ dconf reset -f /org/gnome/settings-daemon/ dconf reset -f /org/gnome/desktop/ If those don't work, and you're desperate, you can try this: dconf reset -f /org/gnome/ And that will reset all GNOME application dconf ...

Jacob got it in the comments! Using the sleep 1; wmctrl -l command, then opening Gnome-Do, I got this output: 0x00e000b9 0 bonus-debian Do Which shows the name of the Gnome-Do window. Then I could use the name to identify the window for xprop: sleep 1; xprop -name "Do" Which gave me the output I was after: $ sleep 1; xprop -name "Do" ...

If you run the script below, it records for 10 seconds (or any other time you set) the output of the xprop command on the frontmost window (running the xprop -root command). Subsequently, it writes the output, after the time has elapsed, to a file: outfile.txt If you make sure to keep the Gnome-Do window active until the script has finished, you can be sure ...

Please try using Firefox instead of Chrome`. Though it is not a perfect solution, it works. I got this idea from a similar question posted here. (Edit 2 in this question has this suggestion).

I forget the exact name of setting its on now (haven't used Nvidia in a while) but it spans across all displays What you need to do is go to open the NVIDIA Control Panel and select "Set up Multiple Displays" From the left pane, choose X Server Display Configuration.

It seems that due to the unconventional way Dell wired up the 3 display ports, the Nvidia GFX and the on-board Intel GFX in the Alienware M14xR2, you cannot use HDMI and MDP for the external monitors. It is also not possible to disable the Intel GFX in bios as Dell wired up the Nvidia card to pass through the Intel card! Using the HDMI and VGA ports for the ...

MonoSLAMglow is an example application for the SceneLib library. So what this means is: If you're a programmer or a developer, this is an extremely useful application as it shows what the library can do. If you're an end-user, this application is of limited use: It contains errors and is not ready for day-to-day use. If you want to convert images, there ...

There is a serious issue with the kernel vs the nvidia driver (https://bugs.launchpad.net/bugs/1401792) In my experience so far with 14.04, I've found that setting any value for 'underscanning' in the nvidia control panel will make this issue go away until the next time you reboot. However, it must be done every time you reboot. I've found no answers on ...

So I don't have an answer (yet) but I'm researching the issue as I will be having a similar problem next week when my NP8651 arrives. I'm looking here for a solution and am working with getting optimus working on a thinkpad 420s (sandy-bridge+nvidia) which should be the same problem. ...

Just because a system uses the X windows system, it doesn't mean it necessarily ships with the header files and development libraries necessary to build X windows based applications - in fact, most don't. If you don't know exactly which X development packages the software requires then, unless your system is severely limited by disk space, probably the ...

I think what you want is Xvnc. It's an X server that displays to VNC instead of a monitor. http://manpages.ubuntu.com/manpages/trusty/man1/Xvnc4.1.html

To start off with, type lspci | grep VGA and take a note of your Graphic card model, just to make sure it is NVidia . You are probably using the xorg open sourced driver right now and high resolution can create problems, as far as I'm aware. To install the unofficial drivers, follow these steps : Press Ctrl + Alt + F2 and login with your credentials. Now ...

In the event that you can't get a working shell from your system, you may need to boot into the installation media (CD, USB) & get a terminal from there.

I thought usually when creating a new user (during installation too), Ubuntu creates a usergroup with exactly the same name as the username. So for example my username is bytecommander and therefore I'm also (the only) member of the group bytecommander. I hope this helps you.

In ubuntu, you can reserve space for your panels with xprop, using the _NET_WM_STRUT_PARTIAL property (the reserved space is called strut). The idea is to get the ID of your panel window with xwininfo, and feed it together with the desired coordinates into xprop -set. If this answer seems to work for you, you can check out my blogpost for a detailed how-to ...

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 instructions directly without linking to their page, this is the best I can do (for now) So please ...

Boot from a livecd - the one you used to install ubuntu should be fine. Or download another one in your windows partition, burn it and boot from that. Mount the filesystem. It will be something like sudo mount /dev/sda1 /mnt If you can't find it, run dmesg | grep sda to discover the hard disks that have been detected by the kernel, and you can mount ...

I was using an old VGA cable with DVI-to-VGA converters on either end to connect the video card to the monitor. At the suggestion of a colleague, I swapped that kludge out for a single link DVI-D cable and after a restart Ubuntu was able to automatically detect the correct resolution and aspect ratio for my monitor.

Running Minecraft on directly on top of the kernel frame buffer is not possible to my knowledge, nor would it be in the developers interest since they would have to implement a lot of stuff themselves that is being done for them in X11 (like input management, display device management, ...).

I found out what was causing the problem. The drivers weren't installed correctly. I found out that Intel does not have support for Ubuntu 14.10, only 14.04. I did a fresh install of 14.04 and now everything is working again.

Best choice would be the binary driver you've selected. Version 331.113 is the most recent version. Tested, I assume, means that it's the most stable version. The difference between binary and legacy drivers is that legacy drivers provide support for video cards no longer supported by NVIDIA. Source: Gladen The "proprietary" bit following the NVIDIA ...
