Independently of your installed version of VirtualBox you should install the latest version of the VirtualBox Guest Additions into your Ubuntu-Guest. You can get it from the Ubuntu-Software-Repository. Startup your guest and hit Ctrl+Alt+T to open a terminal session. Type sudo apt-get install virtualbox-guest-dkms to install the latest package. Restart ...

You basically need the Guest additions, log into the Virtual Machine to install the following packages: sudo apt-get install virtualbox-guest-dkms \ virtualbox-guest-x11 Finally restart the VM to complete the installation.

I had the same problem as you. I did these steps, maybe helps you too: Go to System settings → Software and Updates → Additional drivers Use x86 virtualization solutions... After that reboot your VirtualBox My VirtualBox is working perfectly.

On virtualbox you have to install "Guest Additions". There is no need to set a resolution via Ubuntu settings. From your guest window select Devices -> Insert Guest Additions CD image In Ubuntu open a terminal, navigate to cd folder (usually /media/VBOXADDITIONS*) and run sh ./VBoxLinuxAdditions.run Note that you should have a working compiler ...

Install my Firefox-addon Zoom Menu Elements (or install this file from source on github). Alternative: you can manually open a new tab about:config in Firefox and search for layout.css.devPixelsPerPx set this value to 2 or 1.5 as you wish to adjust the size of the Firefox icons (source, bug report) Install the Firefox-addon Fix for zoomed default-font to ...

After having first tried installing the Guest additions, which didn't work, I found another solution elsewhere: linuxbsdos.com. Use Xdiagnose from the Dashboard. Search for and launch Xdiagnose, then enable all the options under the Debug section. Click the Apply button, then close the window and restart the system. That's what finally did the trick! Now ...

Developing from this answer, and in fact pretty well explained also in this other post. (I really tried everything else posted here but it does not seem to work on my Windows 7 system) Preliminary steps: Make sure you have installed the latest version of Virtual Box(*). Be careful that if you ask Virtual Box to update to the latest version it might very ...

Just had exaclty the same problem with Ubuntu 14.04 on Windows 7 VirtualBox. I've updated to latest version of Virtualbox (4.3.10 r93012) and it now works correctly. Make sure to install the latest version of Guest Additions (v4.3.10 at the moment).

I tried a similar thing and after some debugging I think I figured out what's going on. Your script probably is run and probably does set the resolution correctly. However, since it is run by the login manager, it runs before Unity has finished setting up your desktop environment and Unity reads its own settings and resets the resolution to what you had. So, ...

It is probable that your graphic driver is not detecting that resolution. Follow the instructions below; it might help. It helped me in my Ubuntu(using unity) which installed in my desktop that has a dedicated AMD Radeon 5570HD(which uses Gallium REDWOOD drivers i.e the default open source drivers). First type this in your terminal(You can open terminal with ...

I solved the problem by running: xrandr --addmode VGA1 1366x768 I also added new modes to the change resolution drop down by using, xrandr --newmode "mode line" Where mode line replaces the supported resolutions. You can find the supported resolutions by running: xrandr Currently, it's working all right.

I didn't see any errors in the Xorg.0.log file the radeon driver seems to work well so try to create a Modeline for the unsupported resolution. Open a terminal with Ctrl+Alt+t and type: cvt 1366 768 It should return: # 1368x768 59.88 Hz (CVT) hsync: 47.79 kHz; pclk: 85.25 MHz Modeline "1368x768_60.00" 85.25 1368 1440 1576 1784 768 771 781 798 -hsync ...

Install the latest version of virtualbox say 4.3.10 or above from here and also it's corresponding guest additions, extensions Or you can also install the latest virtualbox version from the multiverse repository via apt-get. I also faced the same problem in older virtualbox version running Ubuntu 14.04 as guest OS. To install guest additions, follow ...

The answer I found was a combination of How do I increase console-mode resolution? and How to use ubuntu server full screen in virtualbox?. The former provided information for changing grub's display resolution, and the latter assisted me in diagnosing why the former wasn't resulting in any resolution change. Combining the two answers: Identify the ...

You did not specify whether you saved your settings to the X configuration file (/etc/X11/xorg.conf) using nvidia-settings. That should solve this. Just open nvidia-settings as root: sudo nvidia-settings Then, choose the right settings and click on the "Save to X Configuration" button: If this does not work, there is something else overwriting your ...

You need to install guest additions. Start a virtual machine, go to "Devices" menu and select "Install guest additions". Windows video driver will be installed. You will be able to set custom resolutions by resizing VM window by your mouse.

Adding complicated commands to Startup Applications In General, you can add commands to run on start up (log in) by choosing: Dash > Startup Applications > Add. In this case, you have a complicated command to run. There are two options to do that: write a separate script: #!/bin/bash cvt 1368 768 xrandr --newmode "1368x768_60.00" 85.25 1368 1440 ...

You don't need sudo to register the new mode with xrandr, try without sudo. Then you'll have to apply the new resolution with: xrandr --addmode <your_connection_type> 1200x1000_60.00 Where <your_connection_type> is usually VGA1, DP1 or HDMI1. Check the output of xrandr to know the exact name of the connected output.

I had this problem, and I seem to have fixed it with the following. I found this thread from the ubuntuforums.org useful. 1) If you need 1280x1024 (what I needed): xrandr --newmode "1280x1024_60_new" 138.54 1280 1368 1504 1728 1024 1025 1028 1069 -HSync +Vsync xrandr --addmode VGA-0 1280x1024_60_new 2) If you need 1440x900 (that's what the guy used, ...

As @Zook pointed out in the comments, it was enough for me to (as superuser) enable and change the GRUB_GFXMODE=1152x864x16 variable in /etc/default/grub and then update-grub && reboot GRUB version is 2.02~beta2-9ubuntu1. Virtualbox version 4.3.16, Windows 7 Host, native resolution 1600x1050. Important for that to work was to remove any vga= ...

For those who already have the guest extensions and additions , you should go check for additional drivers and install the proprietary video driver for virtualbox , then reset your machine

Yes. You can find an explanation in this link Basically, you have to type in your terminal: xrandr --output Monitor_Name --mode 1366x768 --scale scale_factor1xscale_factor2 --panning 1440z810 Note, however, that your scale factor is 1440/1366 = 1.054172767. 810/768= 1.0546875 As you note, both the width and height isn't a good number. The rescaling ...

You or someone else installed an Nvidia driver a wrong way. After each kernel upgrade it stops working. You can install same driver from ppa. In this case it will stay permanently. Run in terminal the commands sudo add-apt-repository ppa:xorg-edgers/ppa sudo apt-get update sudo apt-get install nvidia-352 sudo add-apt-repository -r ppa:xorg-edgers/ppa ...

From https://wiki.archlinux.org/index.php/Xrandr, you can add this section to /etc/X11/xorg.conf or create the file with Section "Monitor" Identifier "VGA1" Modeline "1368x768_60.00" 85.25 1368 1440 1576 1784 768 771 781 798 -hsync +vsync Option "PreferredMode" "1368x768_60.00" EndSection Section "Screen" Identifier "Screen0" Monitor ...

You need to install the VirtualBox Guest Additions into Ubuntu. This gives a few benefits, including resizing the Ubuntu screen to match the host window. Start the VM, then select from the VirtualBox menus: Devices -> CD/DVD Devices -> VBoxGuestAdditions<version>.iso. Then follow the instructions.

Your problem is that you are specifying a TCP port specification (https://) where commands are expecting a host name. ping uses the ICMP protocol, not TCP. For example: $ ping -c 3 http://slashdot.org ping: unknown host http://slashdot.org $ ping -c 3 slashdot.org PING slashdot.org (216.34.181.45) 56(84) bytes of data. 64 bytes from slashdot.org ...

the problem is with the YouTube HTML5 player, I had the same problem and fixed at by installing flash plug-in. then go to this link and choose to disable the html5 player if it's still the default. Afterwards, it should look like this:

HTML5 is usually better (particularly security wise), just Youtube's implementation uses Media Source Extensions, which is available in Firefox but disabled by default currently: Why you can’t play 1080p or 480p YouTube HTML5 videos in Firefox anymore - Nov 5 2013 no option for 1080p youtube - Jan 25 2015 How to get 1080p in Youtube’s HTML5 player in ...

Yes you can, go in : Parameters > Display and set “Scale for menu and title bars” to the value that is best suited for you. It will scale all your desktop while keeping your original 1080p resolution.
