Switch android x86 screen resolution

Question

I would like to use Android-x86 2 2 as an emulator on my Windows 7  I have downloaded VirtualBox and the ISO  and I ve made a virtual machine with it  but I can t set the resolution to 320x480 or something similar     The following tutorial  Using the Android-x86 Port as your Emulator  suggests to insert      lt ExtraDataItem name  CustomVideoMode2  value  320x480x16    gt    to my  vbox file and I did it  Then I added UVESA MODE 320x480 and vga ask to the boot config  When it boots  I have to press Enter to see the available options  but there is no 320x480 among them   How can I get it to work

To change the Android-x86 screen resolution on VirtualBox you need to:

Add custom screen resolution:
Android <6.0:

VBoxManage setextradata "VM_NAME_HERE" "CustomVideoMode1" "320x480x16"

Android >=6.0:

VBoxManage setextradata "VM_NAME_HERE" "CustomVideoMode1" "320x480x32"

Figure out what is the ‘hex’-value for your VideoMode:
2.1. Start the VM
2.2. In GRUB menu enter a (Android >=6.0: e)
2.3. In the next screen append vga=ask and press Enter
2.4. Find your resolution and write down/remember the 'hex'-value for Mode column
Translate the value to decimal notation (for example 360 hex is 864 in decimal).
Go to menu.lst and modify it:
4.1. From the GRUB menu select Debug Mode
4.2. Input the following:
```
mount -o remount,rw /mnt  
cd /mnt/grub  
vi menu.lst
```
4.3. Add vga=864 (if your ‘hex’-value is 360). Now it should look like this:

kernel /android-2.3-RC1/kernel quiet root=/dev/ram0 androidboot_hardware=eeepc acpi_sleep=s3_bios,s3_mode DPI=160 UVESA_MODE=320x480 SRC=/android-2.3-RC1 SDCARD=/data/sdcard.img vga=864

4.4. Save it:
```
:wq
```
Unmount and reboot:
```
cd /
umount /mnt
reboot -f
```

Hope this helps.

Based on my experience  it s enough to use the following additional boot options   UVESA MODE 320x480 DPI 160   No need to add vga definition  Watch out for DPI value  As bigger one makes your icons bigger   To add the previous boot options  go to debug mode  during grub menu selection   mount -o remount rw  mnt vi  mnt grub menu lst   Now edit on this line   kernel  android-2 3-RC1 kernel quiet root  dev ram0 androidboot hardware eeepc acpi sleep s3 bios s3 mode SRC  android-2 3-RC1 SDCARD  data sdcard img UVESA MODE 320x480 DPI 160   Reboot

Verified the following on Virtualbox-5 0 24  Android x86-4 4-r5  You get a screen similar to an 8  table  You can play around with the xxx in DPI xxx  to change the resolution  xxx 100 makes it really small to match a real table exactly  but it may be too small when working with android in Virtualbox   VBoxManage setextradata  lt VmName gt   CustomVideoMode1   440x680x16    With the following appended to android kernel cmd   UVESA MODE 440x680 DPI 120

I d like to clarify one small gotcha here  You must use CustomVideoMode1 before CustomVideoMode2  etc  VirtualBox recognizes these modes in order starting from 1 and if you skip a number  it will not recognize anything at or beyond the number you skipped  This caught me by surprise

In VirtualBox you should add custom resolution via the command   VBoxManage setextradata  VM name   CustomVideoMode1   800x480x16    instead of editing a  vbox file   This solution works fine for me

Set resolution in android x86 Libvirt qemu Temporarily  Add nomodeset and vga ask to android x86 grub entry s kernel loading options  Find your best resolution and note the code you used   Permanently  Convert that code to decimal from hex  Add vga decimal code to your preferred entry in  mnt grub menu lst  mounted if android is started in debug mode

OK  maybe there are more like me that do not have any UVESA MODE or S3 references in their menu lst  First  do  VBoxManage setextradata  VM NAME HERE   CustomVideoMode1   320x480x32   procedure through terminal  My custom videomode was  1920x1089x32      sorry  I use Linux  so procedure works on linux  for Windows  just add  exe to VBoxManage   Look in the first entry as described before  this is the menu entry you would normally boot  I normally use nano as it works more easy for me  And nano happens to be present in Android  6 too   other version not tried   Procedure    Boot VM  chose the  debug mode  option to boot  Pressing  enter  after a while will result in the prompt Change directory to  mnt grub  cd  mnt grub  list directory content with  ls   not necessary but I like to see where I am  copy menu lst  make this standard procedure before changing anything   cp menu lst menu lst bak   or whatever extension you like to use for backup  open menu lst  e g    nano menu lst   look in first menu entry  normally there are 4  starting with the titles you see in the boot menu  the  kernel  entry  which ends with the word  quiet  replace  quiet  with something like  vga ask  if you would like to be asked every time at boot for the screen resolution  or  vga  HEX value   as seen in surlac s anwer  exit and save  don t forget to actually save it  double check this   ctrl X  YES  Enter for nano  reboot VM with  YOUR HOST KEY     R   normally  right control     R     Hope this helps anyone as it did solve my problem   edit  I see that I did place this article in the wrong place  since the original question is about another Android version  Does anyone know how to move it to an appropriate location
