But the images are not of the same size. Their dimensions vary, as you can clearly see in your attachments. You really need to give us a comparison with images that use the same dimensions and compression. Your first shot, from W7 is smaller in dimension, but bigger in file size. This means that there is little to no compression used. The Ubuntu shot is larger in dimensions, but smaller in file size, indicating a higher compression in use. This compression reduces the quality of the shot, so we have no idea what you are actually seeing, if it's as bad as we see the shots.

Ok, I understand, I'll try to shot two images the same size and compression, even if I cannot figure out how to do it.
See you, d.p.

Here is an screen shot of the same image taken from FireFox on Ubuntu 10.10 guest. The original image is actually a JPG which is lower quality but proves there must be a setting in your Ubuntu guest that is compressing the quality of a poor quality graphics.

Indeed this is the problem!

I just started this thread just to solve this.

Which is the "setting in your Ubuntu guest that is compressing the quality of a poor quality graphics." ?

I'd like to find the right setting in order to correctly view in Ubuntu.

Thanks, d.

Nothing special I just have the guest additions installed in the guest.
Are you certain that your install of the guest additions was successful?
Look in the /var/log/Xorg.0.log and vboxadd-install.log and make sure.

Also look and see if there is an /etc/X11/xorg.conf file and if there is post it here.

First I paste the /var/log/Xorg.0.log and vboxadd-install.log, then I paste my /etc/X11/xorg.conf file:

Look in the /var/log/Xorg.0.log and vboxadd-install.log and make sure.

Also look and see if there is an /etc/X11/xorg.conf file and if there is post it here.
I cannot send vboxadd-install.log as attachment since there is a limit in posting length.

The file is too big, maximum allowed size is 128 KiB.

Neither within the post.

These are the final lines of vboxadd-install.log and I suppose there is an error in installation.
How could I correct it?

You should go back to the beginning of this post and click the link I sent that explains what you need to do. Ubuntu 10.04 does not use the xorg.conf file (by default). Doing so confuses it. You can try renaming the /etc/X11/xorg.conf file to xorg.conf.old and reboot the guest. You may need to go through some hoops along the way but you should be able to get to the desktop. Reinstalling the guest additions should not be necessary but you may need to install them again.

I cannot rename /etc/X11/xorg.conf, the rename command is gray out.
How could I rename it?
So should I remove GA before following your instructions?

You rename the file by using the terminal and as sudo. It appears that you are new to Linux and not to familiar with how it works yet.
This is not within the scope of this forum to teach Linux but I will give you the commands to do this but you need to sign up at the Ubuntu forum to find out how to use their product.

<enter> = pressing the enter key
  • Open a terminal and type:
  • sudo -i <enter> put in your password <enter>
  • cd /etc/X11 <enter>
  • ls <enter> (this will show you the files in that folder)
  • cp xorg.conf xorg.conf.old <enter>
  • ls <enter> (make sure that you see the new file xorg.conf.old)
  • rm xorg.conf <enter>
  • exit <enter>
    now either logoff and back in or reboot the guest.
You do not need to remove the guest additions but you may need to install them again.
