Ubuntu 10.04: Yet another GA resolution help request

[myrddin201]

hello,
I've just started using virtualbox and am currently trying to install Ubuntu 10.04. I'm very new to Linux so i'm still having issues with some of the terms and interfaces, but learning fast.

I've gotten the install to go, but i am also stuck at resolution 800x600.
i've run the guest editions and when i reboot, i get an error screen that says "Ubuntu is running in Low Graphics mode. Your screen, graphics card, and input devices could not be detected correctly. You will need to configure them yourself"
when i go into the configuration, the only option that works is "run ubuntu in low graphics mode for one session only" or "exit to terminal"

I've tried to edit the xorg.conf file with the code listed in both this thread as well as the Howto: Install Linux Guest Additions + Xorg config but i keep getting the error xorg.conf is not a valid file and i can't see how to create a new file with that name in the /etc/x11/ folder
I've tried in both the terminal in the "Low Graphic Mode" as well as the terminal i get to when i "exit to terminal"

thanks for any help.

Please see http://forums.virtualbox.org/viewtopic.php?f=8&t=32398 for your problem. It sounds similar to that discussed in the other thread.

Sasquatch,
i read though that thread, and unfortunately, it still didn't help.

Does guest additions not configure the visual drivers for Ubunto 10.04?
are guest additions the only way add resolutions options?
i understand that the xorg.conf file is no longer needed, but according to everything i've read in the Ubuntu forums, it still can be used.

I've created the xorg.conf file in /etc/x11 and entered the parameters listed in the Howto thread, but i still get the same errors on startup.

are these errors a unbuntu issue or a virtualbox issue?

thanks

Virtual box 3.2.1
Host Win 7
guest Ubuntu 10.04

The last post (made by me) tells you what to do. Do that and after you have Ubuntu booting normal again let me know and I will walk you through the installation of the GAs.

perryg,

i renamed and removed the xorg.conf file and re ran the guest additions iso and still have the same issue.
verified that xorg.conf is no longer in the /etc/X11 folder

what am i missing?

thanks

OK first you need to look and make sure that the auto-resize is turned on. Upper top corner of the guest window click Machine and then auto-resize.
Or you can use the host + g toggle to turn it on and off a few times.
Next try the mouse click and drag to see if the screen gets bigger without putting black around the guest window.
Or you can use the host + f toggle to go in and out of full screen.

Let me know what happens.

[myrddin201]

auto-resize is grayed out (host+g) and when i adjust the window, the screen stays the same.
full screen mode doesn't work either. just black around the screen.
thanks

Well the guest additions are not installed then or not properly.
Open a terminal and type the commands below. Let me know what it says.

<enter> = press enter key

sudo -i <enter> type your password <enter>
/etc/init.d/vboxadd setup <enter>

[myrddin201]

Code: Select all

/etc/init.d/vboxadd setup
Removing old VirtualBox vboxvideo kernel module ...done.

You should restart your guest to make sure the new modules are actually used

[Perryg]

OK did you reboot the guest?

[Perryg]

Tell me step by step how you installed the guest additions. What program you used, Etc..

[myrddin201]

i rebooted the guest and still got the running in low graphics mode error on bootup.
i will try to post a picture of it in one hour or so.

i installed Ubuntu, fiddled with the load sequence to get it to load (added acip=off after "ro quiet splash")

clicked devices>install guest additions

mounted vboxguestadditons.iso

on desktop of Ubuntu auto ran CD labeled vboxguestadditions

window popped up and installed

got message at bottom of window to reboot

rebooted and started having low graphics mode errors.

thanks

Tell me why you felt you needed to do this?

Honestly the best way to install Ubuntu in VirtualBox is to let VBox use the default settings. I rarely ever need to change anything.
With 10.04 all I needed to do was use the default. Mount the install iso ti the CD/DVD start the guest and answer yes to everything.
Once the guest is installed I do the following:
Open a terminal and type
sudo -i <enter> type my password <enter>
apt-get update <enter>
apt-get upgrade <enter>
apt-get install dkms <enter>
apt-get install build-essential <enter>
apt-get install linux-headers-generic <enter>
reboot,
Then click on the devices tab and select install guest additions (with 10.04 auto-run works) asked if I want to use auto-run. Say yes, type my password and pres enter. reboot and it all works.

[myrddin201]

it would hang on install and then hang on load unless i added that line.
i found it in the Boot Parameters page (bottom of the page)

I did just mount the CD i burned after i got it to boot, kept hitting yes/ok with only setting date/time location and username/password.

i will download all the things you suggest and get back to you

thanks for your help

[myrddin201]

well, downloaded all the things
re-ran the guest additions
still getting the error.

any other ideas?

thanks
