Default OpenBSD 7.1 resolution in VirtualBox


Due to a problem with my wifi card (see http://daemonforums.org/showthread.p...2528#post72528), the only way I found to run my OpenBSD box with an internet access is to start Win10 (which is the only other system I have also installed on the box), then run OpenBSD as a Guest in VirtualBox directly from the HD, using the trick here:
http://guillaumemuller1.free.fr/show...php?entry=1545 (as OpenBSD is installed on the same HD as Windows).

This works pretty well in text mode. I managed to install / setup almost everyting I need.

Unfortunately, when I start Xorg, it runs with a ~4000x~4000 resolution, which makes it very difficult to use on my 1600x900 screen.

I've tried various tricks that worked in the past :
- Forcing VBox's VM CustomVideoMode
- Use xrandr to change the resolution

But it did not succeed.

In particular the xorg.conf file I copied from the site results in "No Screen Found". And apparently Xorg --configure does not work on OpenBSD. And I don't remember how to setup Xorg manually :[

I tried to play with scaling, both in VBox and in Xorg, but it did not work.

Does anyone have the same problem? Is there a solution?

For some ideas see http://daemonforums.org/showthread.php?t=11734
You can check /var/log/Xorg.0.log for clues why it trying such a high resolution.
You don't need to be a genius to debug a pf.conf firewall ruleset, you just need the guts to run tcpdump

The ArchWiki has a sample configuration file that adds new modelines (as generated by, for example, cvt(1)) and sets the preferred mode:

Default [SOLVED] with "> machine gop 1" before boot

Hi again,

Thanks for the pointers. I already had a look at xrandr and creating new modes, but with no success.

By looking at /var/log/Xorg.0.log, I discovered the driver used is "wsfb", which made me assume that indeed xrandr would not work and I had to focus on the console.

Thanks to the following pages:
I discovered that I can set the console resolution at boot, using:
> machine gop
> machine gop <x>
> boot
and I finally managed to boot my OpenBSD installation within VBox in Windows, so that I'll now be able to debug the wifi connection problems I reported here: http://daemonforums.org/showthread.p...2528#post72528...

Thanks everybody for your help!!!
I thought it would take me ages to find a solution and finally it was a really easy one (as often with OpenBSD when you know where to look ).

See you soon!

By the way, my VirtualBox of OpenBSD, running on FreeBSD, enables me to enlarge it with a
xrandr -s 1280x1024
in my .xinitrc. For me, that's a big help and keeps me from worrying about modelines.
Good luck with your debugging, hope you fix it quickly.
