Dear users, I got interested in Alpine and trying to work on it a
little. I have installed it ("sys" install of v3.10-extended) on a gnome
boxes virtual machine (it uses libvirt and qemu, as I understand).
So after installation, I added all the repositories :
edge/main,community and testing, did update/upgrade and followed
instructions to install Gnome there
https://wiki.alpinelinux.org/wiki/Gnome_Setup (plus xf86-video-qxl
drivers installed).
Launching from gdm (rc-service gdm start) gets a black screen a tenth of
a second and goes back to the terminal. From the gdm greeter.log file,
the failure seems to come from : "Failed to create backend : No GPUs
found with udev". What to do ?
Other things I have tried :
- install MATE and launch it, which works via lxdm (lightdm does not
work). So from lxdm I tried also to launch Gnome but none of the options
worked, all leaving an error screen.
- install Sway, and the same kind of error appears (0 gpu found). (Note
that I need to export XDG_RUNTIME_DIR to /tmp if I want to run sway.)
I have the feeling it is most probably an Xorg configuration issue but
would have expected it to work out of the box but I am not an expert and
could not really find solutions in various forums.
Thank you for your help.
Regards,
Philippe

Sounds like a driver issue.
Did you pass -vga qxl to qemu? I'm not familiar with qxl/spice but according
to here: https://wiki.archlinux.org/index.php/QEMU#qxl
Otherwise, I would experiment with removing the qxl driver so the guest falls
back onto the modesetting driver. Although the page is a little sparse, and
grsec is no longer used, see https://wiki.alpinelinux.org/wiki/Qemu as well if
you haven't already. Good luck.
