Centos inside Virtualbox — how to set custom resolution?
I have Centos inside Virtualbox. I need custom resolution for my screen. I run xrandr as proposed on the net. New resolution appears in the dropdown. But it doesn't work. Virtualbox addons are installed. Virtualbox gives 60Mbs of memory. Here is what I do and what I get:
Popup error message in Russian says: Unable to apply selected configuration, didn't manage to apply CRT 241 controller configuration.

As Dalvenjia sugested, enable autoresize. You can enable all the virtualbox services with the command:$ VBoxClient --clipboard --draganddrop --seamless --display --checkhostversionor use$ VBoxClient-all. Alternatively, you can just tick what you require from the View menu of the running virtual machine.

After adding the mode to the display, you can use xrandr to enable the mode on the display. This can be done with the following command:
xrandr --output default --mode "1600x900_60.00"
Consult the output of xrandr without any options to verify the name of the display output you are targeting is indeed default. If setting the mode fails, you may try creating & setting a mode with different parameters (resolution, refresh rate, etc).

This unfortunately does not work for me, either. Output:xrandr: cannot find mode 1600x900_60.00
