Were you able to open this virtual machine (HVM Debian) in full screen?
I did the same, but my screen resolution cannot be greater than 1920x1080.

@qn00r3
you can simply use the cvt and xrandr commands to add the resolution you want. Then use alt + F11 like in documentation :slight_smile:
Here a tuto to add new resolution:

I use Qube OS 4.2.1
Unfortunately this method does not work.
I created Linux HVM from an ISO image.
I created Linux HVM from a Debian 12 template.
The maximum screen resolution I get in Linux HVM is 1920x1080.
The maximum screen resolution in Windows HVM is 2560x1600.
Maximum screen resolution in dom0 is 2560x1600.

Even in Windows HVM I can achieve a maximum screen resolution of 2560x1600! But I can’t get the maximum screen resolution in Linux HVM, I tried all possible ways.
Please tell me, did you manage to achieve the same screen resolution in Linux HVM as in dom0 ?

Sorry, i wasn’t at home…
I don’t have windows HVM, just debian12 and on 4.2.1.
i try your resolution in th debian12 HVM,
cvt 2560 1440
Modeline "2560x1440_60.00" 312.25 2560 2752 3024 3488 1440 1443 1448 1493 -hsync +vsync
then
xrandr --newmode "2560x1440_60.00" 312.25 2560 2752 3024 3488 1440 1443 1448 1493 -hsync +vsync
then
xrandr --addmode Virtual-1 "2560x1440_60.00"
then go in “Displays” and i find the resolution. I choose it and all is allright.
BUT, i must repeat the commands at every reboot. Without that, all is working :confused:

Thanks for your reply. Please clarify, are you using a laptop or do you have a monitor?
What is the maximum screen resolution in your dom0?
