For me this problem occurred after upgrading from "Ubuntu 12.04 LTS" plus TDE to "Ubuntu 14.04 LTS" plus TDE. TDE is the trinity desktop environment (trinitydesktop.org). The cause of the error was that /etc/X11/default-display-manager pointed to lightdm although during the upgrade I told it to use tdm-trinity as default. lightdm was broken (and I don't ...

You can try to delete the graphics driver. Eg : sudo apt-get remove nvidia-*. And try to install new drivers from tty1 using sudo apt-get install nvidia-current or nvidia-common (depends on your system) and reset compiz and unity

You may have updated the Display Driver. Most of the time the driver that you updated caused the problem. Try using the one that came with the ubuntu distro.

I was having the same problem. The xrandr info in other answers didn't help in my case, but it was good background anyway. I fixed the problem on my screen by resetting the aspect ratio setting back to 1:1. It had somehow been changed to "wide".

I had a similar problem with xcalib only working for 1-2 seconds, and in my case the problem was that I was already running redshift, which repeatedly sets the color settings to what it wants. After I stopped redshift, xcalib worked as intended.

If you don't have dkms installed, and you do a dist-upgrade, you MUST to reinstall the proprietary nvidia driver. First, install dkms so that this does not happen again in the future: sudo apt-get install dkms Now, reinstall the nvidia driver and next time you do a dist-upgrade, the driver will install itself for you. You should be able to boot from ...

This may sound obvious, but have you tried the following? Kmenu > Settings > System Settings > Advanced > Power Management > Edit Profiles Sorry if I was no help at all ¯_(ツ)_/¯

Found a guide for this here, which does load tests. For normal functional tests, the official documentation is here. A sample command for functional tests goes like: sh /opt/app/home/SOAP-UI/SoapUI-5.0.0/bin/testrunner.sh -a -s"Test_Suite2" -r -f/opt/app/home/SOAP-UI/test-project/reports/ /opt/app/home/SOAP-UI/test-project/test-soapui-project.xml

In my case, changing the touchpad in the BIOS to simple made the trick. So it will work as a clickpad but no jittering. Also there is no right buttom as well. Also when it was happening I used to push Ctrl-F7 to disable it and enable it again so that the jittering stop. After changing the touchpad to simple your xinput output should look like: vicente at ...

What you are describing looks like what I recently faced for Ubuntu 15.04. Press Ctrl+Alt+F1, login with your user and password and Try this: sudo apt-get install linux-generic Then go back to your lightdm by pressing Ctrl+Alt+F7. If it is not fixed, try rebooting. Let me know if it works for you.

I had a similar error and the problem was due to my /tmp/ directory having the incorrect permissions and .Xauthority. This Answer worked for me (I copied and pasted it in case it gets removed, @SiddharthaRT is the original author): Press Ctrl+Alt+F3 and login into the shell. Now run ls -lah.

This is just a workaround that save me in two cases I've faced: One was a bad update of gnome-session from a PPA. Another one, I couldn't figure out but all trials left me in front of lightdm. In both cases, I got login loop with lightdm then: I switched to another display manager gdm: sudo apt-get install gdm Reboot, login was successful.

12.04 is not the latest version. 15.04 is the latest version and instead of dist-upgrade I suggest a clean install. Backup all your data and clean install 15.04 and your drivers should be working just fine out of the box. If you find any problem then install again nvidia official drivers but it will work with the updated nouveu drivers included in 15.04.

There have been a LOT of reported problems with Nvidia and the newer releases/kernels. The suggested solutions: Install the xorg-edgers/ppa version of the driver (see Pilot6's answer). That didn't help in my case with the 304 version of the driver (the version was the same as in the standard ppa), your case may differ. Install the nouveau driver. Well, ...

Try to install a version that fixes issues with 340. sudo apt-get purge nvidia* sudo add-apt-repository ppa:xorg-edgers/ppa sudo apt-get update sudo apt-get install nvidia-340 nvidia-prime nvidia-settings sudo add-apt-repository -r ppa:xorg-edgers/ppa But this is for Ubuntu 14.04 with 3.19 kernel, not 15.04.

For me, I just had to switch on the monitor connected via HDMI render it visible in the settings > monitors section. It'll automagically find the monitor. (ubuntu 15.04) HTH

Okay turns out the [drm:intel_dp_start_link_train] *ERROR* too many voltage retries, give up from the kernel is a known bug but was a red herring and had nothing to do with my problems and from what I've seen people say it's not a problem. I think it has something to do with ASUS. I am using ASUS TaiChi 21. Also running systemctl enable for several login ...

The content of the directory /usr/lib/xorg is a little harder to replace than the single binary file /usr/bin/Xorg. You can still do it by just reinstalling packages, but it's made up of many packages, some of which won't apply to you. $ find /usr/lib/xorg -exec dpkg -S {} + | cut -d: -f1 | sed -e 's/, /\n/g' | sort -u xserver-common xserver-xorg-core ...

The solution exists of two parts: 1. create a small script to arrange the screens You should think of your combined screens as one combined virtual screen, as explained here. To arrange two screens into the combined virtual screen, you need to arrange them from left to right. In your case: to place the left screen on 0,0: xrandr --output DP-0 --pos 0x0 ...

To kill all logged in users for :1 use this command: awk '/\s:1\s/ {system("sudo kill -9 "$6)}' <<< $(who -u) In your case user2 user2 :1 2014-08-18 18:21 ? 25745 (:1) Or all sessions for user2 by the username awk '/^user2\s/ {system("sudo kill -9 "$6)}' <<< $(who -u)

I've noticed that the kill command doesn't always work the first time. Also there are times when it'll work, but just have a delayed response. In the case of killing a login session, it most likely takes time for all the processes to die or be killed. So I wrote a script that checks and follows up with subsequent kills that has always succeeded to log out ...

At boot you can press down e and edit the linux line to rw instead of ro and you can edit your system. ro=read only rw=read and write and dont forget sudo before the rm/etc/X11/xorg.conf Good luck

This is only a thought, but it sounds like your hard drive might be mounted in Read Only mode. From a terminal window, type in mount and check for what / is mounted as. root@terrance-Compaq:/etc/X11# mount /dev/sda1 on / type ext4 (rw,errors=remount-ro) after the type you should see the (rw,errors=remount-ro), if not, remount the root partition as Read ...

Assuming that these commands give you read only access sudo nano /etc/X11/xorg.conf sudo vi /et/X11/xorg.conf And that you can't become root with su I'm wondering whether it is possible to sudo mv xorg.conf xorg-old.conf sudo touch xorg.conf xclip -sel clip xorg-old.conf # copy file to clipboard sudo vi xorg.conf # paste xorg-old.conf into the file ...

The xorg.conf does not exist by default any more. You CAN create one though. Boot into recovery mode and select Root Shell. Then run: X -configure Then: cp /root/xorg.conf.new /etc/X11/xorg.conf Reboot and you can edit the new Xorg.conf. You don't even need to reboot, just do sudo /etc/init.d/gdm restart

I'm answering my own question in the hopes that future web-searchers can find a solution sooner than I. Anyways: I was unable to get the HDMI output to work with my third monitor. However, connecting the same monitor to my laptop over VGA rather than HDMI worked instantly. Ubuntu autodetected the monitor immediately. I hope this helps someone in the ...

A short command: ssh -X <username>@<host> gedit & from man ssh -X Enables X11 forwarding. This can also be specified on a per-host basis in a configuration file.

If you don't care to see what the application is doing, you can supply it with a "virtual" x server with xvfb: Xvfb provides an X server that can run on machines with no display hardware and no physical input devices. It emulates a dumb framebuffer using virtual memory. The primary use of this server was intended to be server testing, but other ...

This seems to me very related to: How do I assign a keyboard shortcut that uses AltGr as a modifier key? Keep Right Alt or AltGr as ISO_Level3_Shift and try to use it as Alt Modifier too.
