vboxvideo 5.0.20: resolution issues

[hamelg2]

Hello,

since upgrading my guest to 5.0.20 from 5.0.16, I have now these issues :

1. my linux vm has theses properties :
Key: CustomVideoMode1, Value: 1366x768x32
Key: GUI/Fullscreen, Value: true
at grub and boot time the console resolution is correct, i get 170 columns. But when vboxvideo module is loading, the console switches to 800x600 (100 columns). I see these logs :

Code: Select all

 systemd-modules-load[151]: Inserted module 'vboxvideo'

2. Xserver doesn't choose the right resolution.
The native resolution of my display is 1366x768, and it chooses 1360x768. Xrandr sees these 2 resolutions, i can switch to 1366x768 manually.

Any ideas ?
is it a regression ?

What do you get if you use the Host+F toggle to go to full screen?

Typically the guest will see what is presented since there is no actual monitor connected. I never set the video hint and just use the Host+F toggle if I want full resolution or the click drag to set the screen to a specific size.
