I have installed Ubuntu 18.04 on VirtualBox and the display is not covering the whole screen of the guest OS.

I tried many ways to make a bigger screen in VirtualBox because I do not like the small size of the guest window? Is there is a way to make it big?

I'm trying to enable Wireless on VirtualBox in my Ubuntu 14.04. I use a Kali Linux as the guest OS, but this OS not show the wi-fi when I connect it.    After starting the guest OS, it still does not show the wi-fi     I already tried the suggestions from  and , but my virtualbox does not enable my wireless.

I was using 13.04 as a guest OS on my VirtualBox 14.2.18. Host is Windows 8. After upgrade to 13.10 Ubuntu does not start. I can see a black screen and blinking cursor. I am pretty new to Ubuntu. I suspect a problem with graphics drivers. I can access tty and all files (/home) are there.

I have a MacBook Pro with Touch Bar. I plugged in my external 1080p display (HP 25bw) in clamshell mode and it almost works great - except the screen is too large for the monitor. My dock is too far down off the edge, and my menu is too far up.  For example, when I took the attached screenshot, the Chrome window fills the entire screen I can see:  I have checked and the display options are using native resolution of the monitor (1920x1080 @60hz).  Does anyone have any suggestions for me? Thanks so much.  Note: For any with this same monitor model in the future, thanks to @bmike I found the steps for disabling overscan for this particular monitor model here:

I just updated from Ubuntu 10.10 to 11.04 and have an issue regarding the screen resolution. I have Intel integrated gfx chip and my monitor supports resolutions larger than 1024x768. (in 10.10 I've been using 1280x1024) But as soon as I upgraded, I'm stuck with 1024x768 resolution and seems I can't change it.  running xrandr In terminal yields the following results,   Screen 0: minimum 320 x 200, current 1024 x 768, maximum 4096 x 4096 LVDS1 connected 1024x768+0+0 (normal left inverted right x axis y axis) 0mm x 0mm    1280x800       58.1 +    1024x768       60.0*     800x600        60.3     56.2      640x480        59.9   VGA1 connected 1024x768+0+0 (normal left inverted right x axis y axis) 344mm x 194mm    1366x768       59.9 +    1360x768       60.0      1024x768       75.1     72.0     70.1     60.0*     832x624        74.6      800x600        72.2     75.0     60.3     56.2      640x480        72.8     75.0     66.7     60.0      720x400        70.1     1280x1024_60.00 (0xce)  109.0MHz         h: width  1280 start 1368 end 1496 total 1712 skew    0 clock   63.7KHz         v: height 1024 start 1027 end 1034 total 1063           clock   59.9Hz   What maybe the problem? Is it a bug? What kind of steps I should take in order to get a higher resolution? (changing xorg.conf maybe?) Any insight is highly appreciated. Thanks in advance.   UPDATE    Screenshot after running xrandr --addmode VGA1 1360x768  As you can see, side bar is not completely visible and Ubuntu logo at the task bar is missing. Also when you open an application, the Task bar of the application (where it should go to the top panel) is missing as well..

I've just purchased a new brand laptop with 17 inch size of the screen. I've installed Texmaker and it is messy. The icons are very small and the GUI is not zoomed out automatically to fit the contents of the window. These are pictures         I've already set the size of the icons to medium and the size of apps to 250 (i.e. the recommended size) for  the display.  I'm using Windows 10. Some fonts are blurry and a lot of people are complaining about this problem with no solution from Microsoft. Any suggestions?

I installed Ubuntu 14.04.2 (64 bits) to my Mac OS X 10.9.5 (64 bits) using Virtual Box version 4.3.24. I am not an experienced Linux user. When I start Ubuntu, I cannot make my mouse work in the window that it operates; it disappears in the window most of the time. My keyboard works fine. I checked other questions on similar problems, but couldn't find a suitable solution. I cannot use mouse in Ubuntu (I installed it using my keyboard).  Here are the two messages that appears when I start Ubuntu; the first one relates to keyboard (mostly), the second one relates to mouse:   You have the Auto capture keyboard option turned on. This will cause the Virtual Machine to automatically capture the keyboard every time the VM window is activated and make it unavailable to other applications running on your host machine: when the keyboard is captured, all keystrokes (including system ones like Alt-Tab) will be directed to the VM.    You can press the host key at any time to uncapture the keyboard and mouse (if it is captured) and return them to normal operation. The currently assigned host key is shown on the status bar at the bottom of the Virtual Machine window.    The virtual machine reports that the guest OS supports mouse pointer integration. This means that you do not need to capture the mouse pointer to be able to use it in your guest OS -- all mouse actions you perform when the mouse pointer is over the Virtual Machine's display are directly sent to the guest OS. If the mouse is currently captured, it will be automatically uncaptured.    Any advices?  Solution Edit: I found one way to use mouse in the Virtual Box guest OS window. On the left above menu under the section Machine (on Mac) I clicked the button that says Disable Mouse Integration (Host key + I, Host key is left command key for me). After that I acted as if mouse integration was not available in my machine. Like stated in message 1 (in the above question) I pressed host key. I clicked capture in the box that appears. I can only use mouse in the window, when I want to use it in my host OS I need to hit the host key again. My new question is how can I make Mouse Integration really work?

I've recently done a clean install of 17.04 on a machine with an Nvidia 750Ti card and a Dell 4K monitor. I'm using the Nvidia binary driver 381.09.  All this works great apart from the fact that the display scaling I set in the Ubuntu Screen Display settings always reverts back to 1 when the machine resumes after suspend. I need to set it at 1.5 otherwise everything goes tiny (BTW why doesn't Ubuntu scale to a sensible default with 4K monitors?)  Does anyone else get this? I can't find any mention of it elsewhere.  BTW I've tried the Nouveau driver and that doesn't wake up my screen at all after suspend. So that route's a non-starter.     Edit: Looks like it's been  Will monitor to see if anything happens.

Environment: Lenovo T530 running Windows 7.  Have installed Ubuntu 14.04 on a virtual machine using VM Virtual Box.  Have installed all the updates from both Virtual Box and Ubuntu.  Problem: While in Ubuntu's desktop and other Ubuntu initiated programs, the window is reduced to about 3x4 inches showing in the middle of the rest of my regular Virtual Box window.  I am seeing only the upper right hand of the screen output of what I would normally see.  Please help.   I've seen    But, none of these answers works in 14.04.

I have installed  ubuntu 20.04 on my laptop specification are intel i3 6th gen with intel graphics card 520,screen resolution 1366×768. when i lock desktop to temporarily turn off the screen but when i press power button to wakeup the screen my screen flickers continuously,  this issue occurs only when locking the desktop or when screen goes off automatically. I had same issue with ubuntu 18.04 version and kali linux. But when i downgrade ubuntu to 16.04 it was running fine and same with kali linux when i installed slightly older version of kali linux it was also running fine. I am having this issue with only newer versions of ubuntu and kali linux. I have tried solution of  1)reducing screen size 2)installing older kernels  And also when i installed ubuntu 20.04 on my friends laptop it was also running fine in his laptop, specs are i5 8th gen nvidia graphics card,screen resolution 1920×1080

How do I change the screen resolution in Ubuntu? I am dual booting Vista and Ubuntu. The preferences tab only has one resolution option for my computer.

(Not talking about  as most other questions do.)  I've installed  in VirtualBox 4.3.10 (not .20, which apparently isn't compatible) but the screen won't grow beyond 80x50 or something like that:    I've gone through the , which ultimately fail with an X.Org error. Well, duh. I need a server box, without a window manager.  How do I make the terminal match the resolution of the VirtualBox window?  UPDATE  I've since installed virtualbox-guest-utils and rebooted numerous times. The "Autoresize Guest Display" option is still disabled.  Has nobody else encountered this problem? Or do you just ssh into the box?

I'm trying to install Kubuntu 16.04.1 on a virtual machine (I'm using VirtualBox). When I boot from the disk image Ubuntu begins to load and then I get this screen:   It looks like it's loading but the display is not working properly (the pink blob is my mouse pointer, only very large and pink).  I also tried installing Ubuntu 16.04.1 and I get a very similar result:   Am I missing something in VirtualBox? Thanks!

I get this message while trying to install Ubuntu 12.04 as a guest in VirutalBox 4.1.18, on an Ubuntu 10.04 host.         This kernel requires the following feature not present on the CPU: pae   Some host specs:     The host's kernel is: Linux 2.6.32-41-generic-pae GNU/Linux   lscpu (host): Architecture: i686, CPU op-mode(s): 32-bit, 64-bit   grep --color=always -i PAE /proc/cpuinfo   does show pae in its output.   The 12.04 iso used is: ubuntu-12.04.0-desktop-i386.iso      As a comparison/check, I downloaded and installed Linux Mint 13 Cinnamon to the same host on the exact same VM (I just changed the .iso image). It worked fine. Its iso is: linuxmint-13-cinnamon-dvd-32bit.iso   It seems (to me) that I have pae.. what is going on here?   Update: I had assumed that Linux Mint also required pae (being Ubuntu based), but I've just run;   grep --color=always -i PAE /proc/cpuinfo   in the Mint VM.   It showed no output.   So it seems the issue may lie with VirtualBox.   If that is the case, how can I get Virtualbox into pae mode?

I have a Ubuntu machine that I use as a Plex and data server. There is no monitor connected to it. This wasn't a problem with Ubuntu 16.04, but now, with 18.04, it is and it shows a black screen whenever I connect using VNC. I've already created the virtual display using the answer to this question:   Create a 20-intel.conf file: sudo vi /usr/share/X11/xorg.conf.d/20-intel.conf  Add the following configuration information into the file: Section &quot;Device&quot;     Identifier &quot;intelgpu0&quot;     Driver &quot;intel&quot;     Option &quot;VirtualHeads&quot; &quot;2&quot; EndSection  This tells the Intel GPU to create 2 virtual displays. You can change the number of VirtualHeads to your needs.  Then I made a shell script (don't forget to set executable) and put that in Startup Applications: #! /bin/bash /usr/bin/xrandr -d :0 --output VIRTUAL1 --primary --auto /usr/bin/xrandr --newmode &quot;1600x900_60.00&quot; 118.25 1600 1696 1856 2112 900$ /usr/bin/xrandr --addmode VIRTUAL1 &quot;1600x900_60.00&quot;  After this, it still shows a black screen when I connect using VNC. BUT, when I run this with SSH: export DISPLAY=:0 xrandr  After that, I can see my desktop in VNC... Any ideas on how to fix this? Also, when I see my desktop after all this, the dock is missing and all the icons are in the same spot.
