bhyve Gentoo with X on bhyve

S

I've gotten Gentoo on a vm -bhyve install. I chose profile 3, the default desktop for OpenRC. However, I can't get start X to work. I've tried, after various web searches, install dbus and make sure it's running at boot, installing xf86-video driver for dummy, amdgpu, (which is the host machine), vesa and frame buffer, probably a few other things that I've forgotten. Friends familiar with Gentoo say it shouldn't be necessary, with the desktop profile, to do extra configuration with the kernel, as mentioned in the Gentoo handbook pages on X.
The errors I get are
Code: 
(EE) open /dev/dri/card0: No such file or directory
[   339.776] (EE) open /dev/dri/card0: No such file or directory
[   339.776] (EE) Unable to find a valid framebuffer device

[   339.777] (EE)
[   339.777] (EE) no screens found(EE)

I tried putting in an xorg.conf.d with
Code: 
Section "Device"
    Identifier "card0"
    Driver "vesa"
but no luck.
I emerged xorg-server and openbox. I'm wondering if anyone else is running Gentoo on bhyve, and if so, what video driver are they using. (I'm using uefi boot, basically the same template that allows me to run X without problems on Alpine, Arch, and Fedora, among others).
I install gentoo as I describe at https://srobb.net/gentooquick.html (kind of a long read, I don't think it would have anything useful in troubleshooting).

The host system is a Beelink SER5, with an AMD gpu that works fine. In Alpine, Arch, and Fedora, I don't specify a video driver, in 2 FreeBSD vms, I use the scfb driver, (and did try the fbdevice video driver in Gentoo)
I'm not sure what other information might be helpful, but I've probably left things out, so please let me know.
If you have Gentoo running with X, on bhyve, what driver did you use?

Thanks for any input
 
I think your guest in bhyve would not detect any real GPU unless you do GPU Passthrough. In UEFI boot, i think you should be able to use scfb but i am not sure, never tried it in any bhyve VM.

Maybe VNC related?
 
It's certainly possible, but none of the Gentoo drivers seem to work. As for scfb, I use that successfully in FreeBSD VM's, most Linux ones, I haven't manually added a video driver, it just worked, I would think with either Vesa or framebuffer.
 
Perhaps the VirtualBox, Gentoo guest, Kernel configuration, Graphics support wiki is of some help:
Code: 
    Graphics support  --->
        <*> Direct Rendering Manager (XFree86 4.1.0 and higher DRI support)  --->
            [*] Enable legacy fbdev support for your modesetting driver
        <*> DRM driver for VMware Virtual GPU
            <*> Enable framebuffer console under vmwgfx by default
        Frame buffer Devices  --->
            <*> Support for frame buffer devices  --->
                [*] Enable Firmware EDID
                [*] Simple framebuffer support
        <*> Console display driver support  --->
            [*] Framebuffer Console support
            [*]   Map the console to the primary display device
 
Charlie Brown, it's running fine save for X not working. Not sure if "nice one" means my page or not, but if not, here it is, https://srobb.net/gentooquick.html (A friend is doing something similar for a systemd version).

I'll add that the install using that page only takes 20-40 minutes on a bhyve VM with 8G of memory and 8 cpus, but very little of the time is in compiling, as I'm using binary packages for most of it.

T-Daemon, it seems that the wiki is referring to options in the kernel. I used the gentoo-bin kernel, and did try installing the xf86-video-vesa and fbdev drivers. I'll have to look into editing, or at least checking what's enabled, in the kernel with my Gentoo master friend.
 
You can try to set VIDEO_CARDS="fbdev" in /etc/portage/make.conf and */* VIDEO_CARDS: -* fbdev in /etc/portage/package.use/00video
and then
emerge --getbinpkg --ask --changed-use --deep @world

Also, if not already pulled by emerge, try x11-drivers/xf86-video-fbdev

But no guaranties, I’m also Gentoo noob and running it only in QEMU on Alt Linux 🤷‍♂️
 
I'll give that a try later today. (US, EDT, about 6:00 AM right now, I'll probably get to it in the afternoon). I did already emerge the fbdev driver, that didn't do the trick, but going to try the --deep @world and see what happens.
 
No, sadly, no luck on it. I might just let it go. I'm not super interested in Gentoo--no dislike for it, just no special urge for it. As it was, I'd written a quick Arch howto (https://srobb.net/archquick.html) and my Gentoo friend said, you oughta do one for Gentoo, so I did. Then, once I had it installed, I figured I'd get X on it--I've not had trouble getting X going on Alpine, Void, Open and Net BSD, and several others--and didn't realize it'd turn into such a project. Charlie Brown, if you like, I can send you a message when my Gentoo using friend gets his own systemd guide (which, I think will include X) up.

Yeah ! Definitely share it just here, on that thread. Do you know that there is a Gentoo Discussion chat on conversation app ? Have you asked help on Gentoo's forum ?
 
Charlie Brown I did know about various Gentoo groups, and I haven't asked on the forum. My logic is that I figure this is probably a bhyve issue, rather than a Gentoo one, and I already get in somewhat embarrassing email exchanges with my friend like, Did you read this whole page and me answering, Ahhh, I see, let me try that. But the thing is, is that I'm not all that interested to put in the time. For example, looking at the Gentoo Xorg page, I have to go through and check a bunch of USE flags, etc. I was into Gentoo a lot in the old days--but back then, I feel as if it was a lot more important to make err, use of the USE flags, and so on, but now that even cheap computers are so relatively powerful, it's (to me, at least) of less importance. (Also, I'm not a developer, I'm a sysadmin by trade, so getting every bit out of my computer so it'll compile faster isn't that important for me).
Lastly, I'm very lazy when something doesn't interest me that much. For example, when I couldn't get Wayland working on FreeBSD, I was willing to try all sorts of things and combinations, (spoiler--it was fixed with an update to Nvidia drivers or kmods, I forget which), but even if I got X running in Gentoo, I'd probably just run it once or twice.
(The thanks is for the suggestions, by the way). :)
 
I want all the time I wasted keeping my Gentoo server updated back! Seriously, though, if there's one thing that's true about installing and maintaining a Gentoo host is that it's neither quick nor easy. Just about the only thing I miss is the ability to skip using an initrd. I don't miss it enough to roll my own kernels in Void, though.

If you don’t want to compile latest pkgs and want to save time with installing bin ones, check Gentoo Binary Host Quickstart and Binary package guide.
Don't use ACCEPT_KEYWORDS="~amd64" in /etc/portage/make.conf
 
And seeing what both vmisev and Jose are saying, I think more and more that I'm giving up on getting X working on bhyve. I'm a bit impressed with myself that I managed to get my quick guide done. :)
