Virtual Guest Additions crashes Fedora 12 x86_64 Guest

[AntoineSolutions]

Hi,

I am trying to build a guest machine identical to my host machine for development purposes. I am using Fedora 12 x86_64 OS for both machines. Without the Guest Additions installed, the guest OS boots up normal and runs fine. When I install the Guest Additions and reboot, the boot process appears to be normal, but when the progress bar finishes and the GUI should load, I just get a black screen with a white cursor at the top. It seems to be a problem with loading the GUI. I have attached my Xorg.0.log log file. Below is the error I found in the log file.

(EE) Screen(s) found, but none have a usable configuration.

Fatal Server Error:
no screens found

Thanks for any help in advance.

Cheers,

Antoine

Dump the existing xorg.conf file, as it's trying to load 3 video drivers. Grab my example, maybe add a video mode if it's not working.

Hi Sasquatch,

Fedora doesn't use an xorg.conf file. They us HAL. Any other ideas?

Cheers,

Ubuntu uses HAL too, but it also checks xorg.conf. Did you even try?

Sasquatch,

I had already tried your xorg.conf file without success, but for kicks I tried it again and have attached the xorg.0.log file. I'm not sure how to add a "video" mode, but if you think it would help, I'll add it to the file. Could you give me an example and tell me at what line I should paste it into the Xorg.conf file?

Cheers,

Antoine

On the first bootup after install the Virtualbox Guest Additions, I get this error on the screen following the 100% status bar:

type=1305 audit(12587840002.571:32444): audit_enabled=0 old=1 auid=4294967295 ses=4294967295 subj=system_u:system_r:readahead_t:s0 res=1

Not sure what it means, but I hope it helps in figuring out what is going on.

Cheers,

As a "temporary" fix, I've had to specify the Screen Mode manually. Here is an xorg.conf configuration that works for me:

Code: Select all

Section "Device"
	Identifier	"Configured Video Device"
	Driver		"vboxvideo"
EndSection

Section "Monitor"
	Identifier 	"Configured Monitor"
EndSection

Section "Screen"
	Identifier	"Configured Screen"
	Monitor		"Configured Monitor"
	Device		"Configured Video Device"
	SubSection "Display"
		Depth	24
		Modes	"1680x1050" "1920x1200"
	EndSubSection
EndSection

Section "InputDevice"
	Identifier	"vboxmouse"
	Driver		"vboxmouse"
	Option		"CorePointer"
	Option		"Device"	"/dev/input/mice"
EndSection

Section "ServerLayout"
	Identifier	"Default Layout"
	Screen		"Configured Screen"	0 0
	InputDevice	"vboxmouse"
EndSection

Note that this will disable support for automatic resizing of the display resolution.

I say "temporary" as I'm hoping a fix will be available soon to avoid having to specify the mode manually! (Ref: http://forums.virtualbox.org/viewtopic. ... 88#p110806).

Jits,

Thanks for providing me an xorg.conf with video modes. This fixed my problem.

Cheers,

I'll add the part in my howto for what is needed for the modes thing, in case others use a distro that refuses to start X without a specific resolution.
