qemu FreeBSD 14 on QEMU on MBP M2

[eirannejad]

Hello all,
I have been trying to get xorg display server to work on my freebsd 14, running on qemu (UTM.app), and with virtio_ramfb display attached to it. No matter what xorg configuration I apply, `xinit` either can not find the display or fails on "AddScreen" (using the scfb driver).

I am not a very advanced user. Any help and walkthroughs here would be greatly appreciated.

… No matter what xorg configuration I apply, ` …

Have you tried startx without attempting to manually preconfigure X.Org?

 

[eirannejad]

I have. That the first command I tried after installing xorg. Based on the man pages it seems like it is a wapper over xinit so after running into problems I tried to manually configure and test running xinit. Are you running xorg successfully in QEMU on an ARM MackBook?

Is x11-drivers/xf86-video-scfb installed? It's included with the "full" x11/xorg but not with x11/xorg-minimal.

 

[kpedersen]

After running startx, can you post your xorg.log here?

(You can find it in ~/.local/share/xorg/Xorg.n.log)

If it can't find the display or screen, perhaps there is some hint in there as to why they aren't attaching correctly.

Additionally, as a workaround, you can likely sidestep this issue using either of the following:

• tigervnc's Xvnc server - Stream graphics via a VNC server
• X11/ssh and XQuartz - Forward X11 instructions via SSH into a native Xserver running on the host

This is what the logs look like after running startx

It is a full system install so I am assuming the drivers are installed. I can see the `scfb_drv.so` under xorg libs so I guess that is a yes.

I am using qemu from MacPorts rather than UTM, but I also had trouble with the framebuffer. Instead, I used x11-drivers/xorgxrdp in my aarch64 FreeBSD vm, then forwarded the vm's port 3389 to my host, and connected with MacPorts' net/FreeRDP, as Microsoft's Remote Desktop app did not seem to allow arbitrary ports. I was able to get the x11/mate metapackage installed and working, and www/firefox/ is working. I have not really pushed the graphics too hard (video, games, etc). Using RDP instead of a framebuffer might not work for your use case, depending on expectations.

I have the same issue, running FreeBSD 14.1 under UTM on M1, Xorg.0.log is the same, scfb driver is installed.

FYI, here is a similar thread.

(Apple M1) startx will not run driver error

Can you please help? I am using UTM on the Apple M1 I get the following error when I attempt to start startx. AddScreen/ScreenINT failed for driver 0 pkg install drm-kmod does not work Anyone know what graphics driver I should be using?

I'm struggling with a similar problem.
M1 Mac, UTM/QEMU, FreeBSD 14.3 – want to get Mate running.
x11-drivers/xf86-video-scfb are installed

I have also tested this:
/boot/loader.conf the following kernel modules :

virtio_load="YES"
virtio_pci_load="YES"
virtio_blk_load="YES"
virtio_balloon_load="YES"

I this necessary or should I delete this?

The good thing is that I cloned the pure FreeBSD installation, so I can quickly start again from scratch.
Since switching to M1 Mac, I haven't been able to get FreeBSD to run with a GUI.
Step-by-step instructions would be helpful, please in text form and not a YouTube video.

startx don't start X
PCI Bus and xorg.log

In which file I must set the bus information and which driver? And which monitor Information?

Kapitel 5. Das X-Window-System

docs.freebsd.org

 

[Phishfry]

In which file I must set the bus information and which driver?

The file name itself is unimportant. The key is it must start with 20-*.conf
It can be 20-intel.conf or 20-display.conf.

This is the proper file location:
/usr/local/etc/X11/xorg.conf.d/20-display.conf

You video is on the typical PCI bus:
BusID "pci0:0:2:0"

This chapter describes how to install and configure the X Window System providing a graphical environment

Whats about /boot/loader.conf kernel modules, are necessary or should I delete (# preface) this?

My FreeBSD

 

[Phishfry]

From what I am reading there is a video driver for QEMU.

x11-drivers/xf86-video-qxl

I don't know if it works.

Looking here:

The Elusive BSD Desktop on QEMU / KVM

FreeBSD Desktop on QEMU / KVM still requires additional configuration, but GhostBSD is getting close to providing an "out of box" installation, that works

just.graphica.com.au

You would need to load QEMU USB Tablet driver for a mouse.
utouch_load="YES"

Install the qxl driver and create a video driver file:
/usr/local/etc/X11/xorg.conf.d/20-display.conf

Section "Device"
    Identifier "Card0"
    Driver     "qxl"

just ditch the x server and install xrdp
then use remote-desktop app on the mac host to connect to the utm guest
performance is good
in rc.conf
xrdp_enable="YES"
xrdp_sesman_enable="YES"
in /usr/local/etc/xrdp/startwm.sh uncomment exec startxfce4 (or whatever wm you want) and comment exec xterm
use msft remote-desktop "Windows App" to connect

just ditch the x server and install xrdp

I tend to agree. To make things feel a snappy as possible, you want as much of the rendering to happen on the native host. Xrdp, Xvnc and X11/ssh tend to fair a little better than the emulator rendering everything itself through the virtual display stack.
