 Posted: Sat Sep 24, 2022 6:37 pm Post subject: [SOLVED] Unable to start graphical session Xfce |
 |
|
Good evening,
I installed Gentoo Linux as a guest system with Virtual Machine Manager (KVM, Qemu, Libvirt, Virt-Manager) on an Arch Linux host system. Installation is unfold without particular difficulty.
For installing Gentoo Linux, I followed the official Gentoo AMD64 Handbook documentation. For installing and configuring Kernel, I used the manual method (make menucongig, make, make modules_install, make install).
Thereafter, I modified the basic profile (Profile no 1 with OpenRC) and I moved to desktop profile (Profile no 5 with OpenRC). I did a full system update.
Subsequently, I modified the /etc/portage/make.conf file and installed Server X (x11-base/xorg-server x11-base/xwayland x11-drivers/xf86-input-libinput x11-drivers /xf86-video-fbdev x11-drivers/xf86-video-qxl x11-drivers/xf86-video-vesa x11-apps/xinit x11-apps/xhost x11-apps/xrandr x11-apps/xsetroot x11-apps/setxkbmap) .
I continued by installing Lighdm and Xfce.
But I can't get Xfce GUI. I tested with user account and root account with ligtdm and startx. In both cases, it is impossible for me to have a graphical interface.
For several days I have been searching the internet, but I can't find a topic similar to my case (Installing Gentoo Linux as a guest system with Virtual Machine Manager (KVM, Qemu, Libvirt, Virt-Manager)).
I need help diagnosing and solving the problem.
Please find below some system files that may be useful for problem diagnosis.

Cordially

Extra kernel config needed for Gentoo as KVM guest.
Plz see
https://wiki.gentoo.org/wiki/QEMU/Linux_guest
You are missing
| Code: |
CONFIG_VIRTIO_PCI_*
CONFIG_HW_RANDOM_VIRTIO
|
and maybe others.
Just plz follow the above wiki.

@alamahant
Thank you for your reply.
I had seen and read the Qemu (https://wiki.gentoo.org/wiki/QEMU) and QEMU/Linux guest (https://wiki.gentoo.org/wiki/QEMU/Linux_guest) documentation and I I have activated the indicated options. But I think I didn't do it right. I will review the Kernel documentation and configuration.
Thank you and good evening. |

Hello
I reviewed the documentation and the kernel configuration. I find no anomaly.
The VM starts well, the kernel loads well, but when displaying Lightdm it's the black screen.
As the VM goes to black screen, I can connect to VM in SSH from the host system.
I did enable framebuffer option in kernel config.
Here is the return of the commands about connection manager.
| Code: | # /etc/init.d/display-manager status
* status: crashed |
| Code: | # /etc/init.d/display-manager stop
* Stopping lightdm ... |
| Code: | # /etc/init.d/display-manager start
* Setting up lightdm ... |
| Code: | # /etc/init.d/display-manager status
* status: crashed |
I can't find what's preventing it.
Does anyone have any other ideas? |

Did you make the suggested changes to your kernel?

Well this
| Code: |
CONFIG_HW_RANDOM_VIRTIO
|
does not reflect your .config
| Code: |
# CONFIG_HW_RANDOM_VIRTIO is not set
|
You have posted two different configs.
| Code: |

Yes please kindly do not edit your pastebins--if you do-- because it is confusing.
I advice you to
| Code: |
emerge -av dracut
emerge -av gentoo-kernel-bin
grub-mkconfig -o /boot/grub/grub.cfg
reboot
|
Let us check if you can boot this way and then work more on what is wrong with your current setup.

Again these errors are NOT reflected in your xorg logs you provided.
You have the habit of changing the provided matterial(by you).

I told you you had a segfault already.
This WAS in your original logs.

It's true that I've been working on Gentoo Linux for a few days as the content of the /usr/src/linux/.config file and the content of the Xorg.0.log files can be modified slightly.
This is the reson for which I modify the links and I put the new pastebin links. But the main problem remains the same.
In the meantime I changed the host system. I moved from Arch Linux to Debian.
I am sincerely sorry if I have created confusion and gene. |

Updating linux-5.15.68-gentoo to linux-5.15.69-gentoo and installing gentoo-kernel-bin and dracut didn't change anything. The Gentoo system has absolutely the same behavior.
I have a question: How do you go from a source kernel or kernel-bin to a genkernel? |

To which kernel have you booted?
Plz post
| Code: |
uname -r
and also
ls /boot
|
Genkernel is not a kernel but a tool.
