It's suggesting you install Utopic-level packages over Trusty (which Trusty allows through its HWE stacks). You're already on Utopic so you don't need to do what it's saying at all. It likely won't be able to find many of those packages. But Utopic is dead and not getting security updates. If I were you, I'd upgrade to Vivid before doing anything and then ...

Yeah you can mount another installation and trick it into thinking you're using it. It's called chroot. Boot to your Live environment and open a terminal. We need to start by finding out what the real installation partition is called. It'll look like /dev/sdb1 but use sudo fdisk -l to find out for certain. sudo mount /dev/sdb1 /mnt for i in /dev /dev/pts ...

I have had the same problem for a long time and I think I have found the solution. I have Ubuntu 14.04 LTS, my graphic card is Nvidia GTX 860M. The problem of black screen or freezing on the splash screen is related to nvidia-drivers and openGL libraries that cuda installs alongside. So here what happens: First you install the graphic card driver which ...

Have you tried this: sudo apt-get install --reinstall unity sudo dpkg-reconfigure unity dconf -reset /etc/X11/xorg.conf and it might work fine this way.

There is this script secReplaceWindowManager.sh. Each 10s it will check if there is a window manager running, if not, it will start it; you can also replace them at will (currently it supports compiz and metacity). It is interactive so requires to be run on ex. a xterm like xterm -bg darkorange -e "secReplaceWindowManager.sh;bash"&disown.

You don't need to configure your monitor's resolution with xrandr actually. You need to modify your xorg.conf file (which contains X Window configurations) to include the horizontal sync and vertical refresh rates that match with your monitor. First of all, google your monitor name and find a site that lists its horizontal sync and vertical refresh rates; ...

An extra display under System Settings => Display is causing the error. You have to disabled it.

Official answer on a dell forum. Says "A maximum resolution of 2048 x 1152 through the U2515H HDMI in means that the signal it is getting from the video card is not HDMI 1.4. It is HDMI 1.3. Which is why you are getting 2048 x 1152." You might want to check the spec on your GPU, to see what version of HDMI it supports.

I have solved the issue. I managed to create a .xprofile file and saved it to the home directory. I then added xrandr --newmode "1280x1024_60.00" 109.00 1280 1368 1496 1712 1024 1027 1034 1063 -hsync +vsync xrandr --addmode VGA1 "1280x1024_60.00" The only trouble I had was permissions with saving a .xprofile which somehow was not an issue when I did ...

After log-in attempt it drops me to login screen again So you installed the X server and a login manager. But did you instal a desktop/window manager? Like Metacity, Openbox, etc.? To resolve your problem: See if you can choose a desktop/window manager in lightdm. If not, try to install one like apt-get install fluxbox or so. If still not working, ...

You can install the latest drivers by adding the brand-new NVIDIA PPA: sudo add-apt-repository ppa:graphics-drivers/ppa And installing or upgrading the drivers: sudo apt-get update && sudo apt-get install nvidia-355

This is what bothers me: xrandr: Failed to get size of gamma for output default Try changing the resolution via xrandr. Also try using older drivers that worked. Is it a big issue for you if you can't use the proprietary drivers?

This seems to have been a problem with the .Xauthority file in the home directory. It should be recreated if you delete it, upon restarting the X server. I entered rm $HOME/.Xauthority* and rebooted, and can now launch applications.

Sometimes I did not have time or courage to do it Once is enough. All the other reports will error out with a message that this case is already registered (that is if it is the same error). I thought this would be solved with the next upgrade of Ubuntu Often that is the case. But bugs also can be marked as invalid, or as won't fix, or as ...

I ended up reinstalling, somehow the network drivers were uninstalled too, which made it so i was unable to download the packages needed or repair.

Okay, I got what the problem really was - it was related with the connector I used. There's no way to fix it another than changing connector to converter as far as I'm concerned.

You need to make the xrandr commands run on startup. Unfortunately, a lot of people have trouble making the commands permanent, so that they run on startup, but I'll show you how to do it the easy way: Create a bash script, xrandr.sh for example, and place your xrandr commands into it. It should look something like this #!/bin/bash xrandr --newmode ...

The errors you see are symptomatic of a missing X authorization file. I've has a similar problem running any GUI application as root in Ubuntu 15.04, and I discovered that it was because Ubuntu was giving the root user an invalid environment variable. So: from your Oracle user, see if "echo $XAUTHORITY" gives you a path that actually exists. If not, copy ...

First, login using the text user interface. Then, you can either: Remove your xorg.conf file with sudo rm /etc/X11/xorg.conf Or: Remove the line from the file by editing it with nano -> sudo nano /etc/X11/xorg.conf I would recommend the second option. Both will solve your problem and on reboot you'll have your GUI back.

The nvidia-331 packages are left for compatibility only, they just pull nvidia-340 packages. You have nvidia-340 installed. There is nothing to worry about.

I got this same issue using R in Ubuntu 14.04 specifically with the GGALLY package and the GGPAIRS function. To recreate: data(mtcars) library(GGally) mtcars_subset <- mtcars[,c(2:11)] ggpairs(mtcars_subset) Error: Warning message: Error in grid.Call.graphics(L_text, as.graphicsAnnot(x$label), x$x, x$y, : X11 font ...

Finally got it... Triple check the output of /var/log/Xorg.0.log to remove as most as you can errors and warning. I mispelled one of my output DVI-O instead of DVI-0... So, if you encounter this problem, the solution seems to be : Describe as most as you can your configuration in /etc/X11/xorg.conf : device section with Options "AccelMethod" "glamor" / ...

Perhaps the solution would be to put the same changes into a script, set it as executable and let it run as a startup program.

You can use apt-mark hold to prevent a specific package from upgrading to a newer version. Run the following commands install the version and to hold the package so that it doesn't upgrade: sudo apt-get install xserver-xorg-video-intel=2:2.99.914~1~exp1ubuntu4.3~trusty1 sudo apt-mark hold xserver-xorg-video-intel=2:2.99.914~1~exp1ubuntu4.3~trusty1 To ...

Displaylink just released a Linux driver for USB 3 devices: http://www.displaylink.com/downloads/ubuntu.php I tested it under Ubuntu 15.04 with Dell's USB3-Ethernet/VGA/HDMI adapter and it kind of worked, although the recognized display resolution was too low. Also, I have to re-run the installation script after every reboot

I just had a similar problem with my Radeon HD 4650, and spent a lot of time looking for the solution. I finally found help here. As instructed, I removed the word nomodeset from /boot/grub/grub.cfg, and then regenerated grub by doing grub-mkcofnig -o /tmp/grub.cfg. Note: I did the editing of grub.cfg with gedit, which I started in terminal with the ...

You may need to run: sudo apt-get build-dep nvidia-331 or similar, before installation. I'm on my phone right now but you can run apt-get --help If you get command not found. This should install the dependencies needed to execute the build.

If you do a ps alxww|grep X you should see that your X server is running with the option -auth followed by some filename. This file holds a random number called the MIT-MAGIC-COOKIE-1. Only X11 clients that can present this number to the X11 server in the protocol startup are allowed to connect. Apps run by the same user who started the server will find ...

First, to give access only to the Gitlab CI runner, you need to use a more restricted command: xhost +SI:localuser:gitlab-runner Second, /etc/rc.local runs way too early for this command to have effect, and further, you need to set $DISPLAY for it to work. It depends on how your X server is being started. If you're using LightDM, I think you can make it ...
