[SOLVED] virtualbox com object??

[ftriscari]

Hi
I'm new to Mageia. I'm trying to install virtualbox but I'm unable to start the application.

I have installed the program from the control center and I added my user to vbox users group. I'm running 3.12.13-desktop-2.mga4.

when I try to start the program from console it doesn't work and I get the following message

Code: Select all

Qt WARNING: libpng warning: iCCP: known incorrect sRGB profile


however the application starts if I log in as super user with the same error as above.

any idea?

thanks for your help

Well, those are only warnings and don't prevent virtualbox from starting.

This is what I've installed:

Code: Select all

[doktor5000@Mageia4 ~]$ rpm -qa | grep -i -e virtualbox -e png | sort
lib64png-devel-1.6.8-1.1.mga4

no luck yet...
virtualbox starts from terminal if I log in as superuser...not from my normal account.

It appears that I can only run Virtualbox as Superuser.
This is not a major problem for me but I would like to know if this is a cause of concern in terms of security. In other words, is it safe?
Thanks

Question is why. Virtualbox runs fine here as normal user. Please run the following command in a terminal as normal user and post the output here:

Code: Select all

VirtualBox

[ftriscari]

the output is...

Code: Select all

Qt WARNING: libpng warning: iCCP: known incorrect sRGB profile

[doktor5000]

And virtualbox doesn't start?

Please also post the output of

Code: Select all

id

as normal user

[ftriscari]

no, it doesn't start

the output from id is

Code: Select all

uid=500(francesco) gid=100(users) groups=100(users),43(usb),477(vboxusers),478(vboxsf),490(usbmux),500(francesco),65534(nogroup)



[doktor5000]

Why did you add yourself to nogroup ? Also vboxsf group is only required in a virtualbox guest, not on the host.

[ftriscari]

not sure...I removed my account from those groups but no change.

[Ken-Bergen]

I don't know if it would help but try changing your gid to =500(francesco).

[ftriscari]

could you tell me how to do that?

[doktor5000]

As root

Code: Select all

usermod -g francesco francesco

[ftriscari]

As root

Code: Select all

usermod -g francesco francesco

Hi Doktor5000
I tried what you said but no change...still unable to start VirtualBox as normal user...
FT

[doktor5000]

After the group changes, did you logout and login again or did a reboot?

[ftriscari]

I rebooted, still the same. Only Superuser can start VirtualBox.

It's possible that when using su or sudo when starting virtualbox you have inadvertently set some root file ownership in your home directory.
Use chown -R francesco:francesco /home/francesco/.VirtualBox and again for /home/francesco/VirtualBox\ VMs as root to set ownership back to your regular user if that is the case.

[ftriscari]

It works!
thank you for your help!

It's not generally advised to use GUI applications as root, it can cause issues such as this.
When you do su to root though remember to do "su -" rather than just "su".
