virtualbox - unable to change resolution

Post by Mr.Sabyon » Fri May 15, 2015 21:06

After last update of sabayon image in VB I cant adjust screen resolution. I tryd another virtual with fedora a theres no problems. I did reinstall VB addons in sabayon image but nothing change.
Inside VB image: lsmod | grep vb
vboxsf 28082 1
vboxvideo 1838 1
drm 215721 3 vboxvideo
vboxguest 158756 6 vboxsfLinux

VB host: lsmod | grep vb
vboxnetflt 12558 1
vboxnetadp 45456 0
vboxdrv 544566 4 vboxnetadp, vboxnetflt

So, problem is definitely in kombo of sabayon and VB.

I have the same problem. Resolution auto-resizes with older snapshots of my Sabayon VMs but once upgraded with rigo or equo it stops working. I noticed the resolution falls to 16 bit 1024x768. I thought maybe the xorg config got messed up somehow. Not too knowledgeable with xorg. I could change the color depth and resolution with grub vga modes but auto-resize does not work. When I compare the older snapshots to the fully updated one I don't notice anything special. Rigo shows all the same vbox modules, xf86 video, guest additions, etc installed. I don't know where to start but I believe the problem lies with the guest OS because from the same host the older guest resize fine. Even when booting a current daily KDE live iso as a VB guest from a current Sabayon host auto-resize does not work. Any help is welcome.

Uninstall guest additions using equo, then install them using the installer provided by VirtualBox.
It worked for me. :D

I think I'm running into this same problem. In my case, I only have 1024x768 listed in my Display resolution config, and auto resize of the guest window does not work (just stays stuck at 1024x768).

According to Xorg.log, I'm having an issue loading vboxvideo_drv.so:

Code: Select all

[     6.676] (II) LoadModule: "vboxvideo"
[     6.676] (II) Loading /usr/lib64/xorg/modules/drivers/vboxvideo_drv.so
[     6.677] (EE) Failed to load /usr/lib64/xorg/modules/drivers/vboxvideo_drv.so: /usr/lib64/xorg/modules/drivers/vboxvideo_drv.so: undefined symbol: vgaHWFreeHWRec
[     6.677] (II) UnloadModule: "vboxvideo"
[     6.677] (II) Unloading vboxvideo
[     6.677] (EE) Failed to load module "vboxvideo" (loader failed, 7)
Google hasn't turned up much help for other people that have the same "vgaHWFreeHWRec" error (and even if it does, it's from people running Gentoo that just say to re-emerge virtualbox-guest-additions using a different GCC profile).

I currently have the following installed (note that I've tried going all the way up to linux-sabayon-4.0.4, but that still has the same problem):
  • sys-kernel/linux-sabayon-3.15.10
    app-emulation/virtualbox-guest-additions-4.3.28#3.15.0-sabayon
    x11-drivers/xf86-video-virtualbox-4.3.28#3.15.0-sabayon

This seems to have resolved itself after the last few system updates, and re-installing the latest 4.0.0 kernel. One of the main reasons I love Sabayon, keep up the great work!
