copied!<p>To change the Android-x86 screen resolution on VirtualBox you need to:</p> <ol> <li><p>Add custom screen resolution:<br> Android <6.0:</p> <pre><code>VBoxManage setextradata "VM_NAME_HERE" "CustomVideoMode1" "320x480x16" </code></pre> <p>Android >=6.0:</p> <pre><code>VBoxManage setextradata "VM_NAME_HERE" "CustomVideoMode1" "320x480x32" </code></pre></li> <li><p>Figure out what is the ‘hex’-value for your <code>VideoMode</code>:<br> 2.1. Start the VM<br> 2.2. In GRUB menu enter <kbd>a</kbd> (Android >=6.0: <kbd>e</kbd>)<br> 2.3. In the next screen append <code>vga=ask</code> and press <kbd>Enter</kbd><br> 2.4. Find your resolution and write down/remember the 'hex'-value for <code>Mode</code> column</p></li> <li><p>Translate the value to decimal notation (for example <code>360</code> hex is <code>864</code> in decimal).</p></li> <li><p>Go to <code>menu.lst</code> and modify it:<br> 4.1. From the GRUB menu select <code>Debug Mode</code><br> 4.2. Input the following: </p> <pre><code>mount -o remount,rw /mnt cd /mnt/grub vi menu.lst </code></pre> <p>4.3. Add <code>vga=864</code> (if your ‘hex’-value is <code>360</code>). Now it should look like this: </p> <blockquote> <p>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</p> </blockquote> <p>4.4. Save it:</p> <pre><code>:wq </code></pre></li> <li><p>Unmount and reboot:</p> <pre><code>cd / umount /mnt reboot -f </code></pre></li> </ol> <p>Hope this helps.</p>
