Ubuntu 7.10 - Quick Fixes
Author: ndaru5 Nov
As I didn’t have much luck with Ubuntu upgrade, this time I install Ubuntu 7.10, fresh. Still, it doesn’t stop the problems that show up on Ubuntu upgrade. Here are some quick fixes for Ubuntu 7.10:
1) Can’t connect / browse the net
This has something to do with bug #81507. Ubuntu 7.10 activates IPv6 by default and in this case, we need to deactivate IPv6.
gksudo gedit /etc/modprobe.d/aliases
Look for a line which contains alias net-pf-10 ipv6. Change it to alias net-pf-10 off.
Save changes. Restart Ubuntu.
2) Can’t update / keep redirected to address 1.0.0.0 instead of archive.ubuntu.com
This is also related with bug #81507. This may not be a good solution, but you can somehow correctly redirected to archive.ubuntu.com by pinging it before you update.
ping archive.ubuntu.com
In my case, the update runs smoothly. Other reports that the update runs slowly.
3) Trouble activating compiz / 3D desktop
To activate compiz, we may or may not need to activate the restricted graphic card drivers. I use ATI Radeon X300 and I’ve managed to activate compiz without using the restricted ATI drivers. Anyway, we need to install compiz.
sudo aptitude install compiz compiz-core compiz-fusion-plugins-extra compiz-fusion-plugins-main compiz-fusion-plugins-unofficial compiz-gnome compiz-plugins compizconfig-settings-manager libcompizconfig-backend-gconf libcompizconfig0 python-compizconfig
Restart X by pressing Ctrl+Alt+Backspace. Try to open System/Preferences/Appearance and choose Visual Effects tab. If succeeded you should see four (not just three) different desktop environments.
If not, then you need to install the restricted drivers. Open System/Administration/Restricted Drivers Manager. Check to enable the accelerated graphics driver. Restart X.
Open the Visual Effects menu again. If you’ve got “The composite extension is not available” message, open X configuration file.
gksudo gedit /etc/X11/xorg.conf
Look for a line which contains Option “Composite” “0″. Change it to Option “Composite” “1″. Save changes. Restart X.
Open the Visual Effects menu again. This time if you’ve got “Desktop effects could not be enabled” message, then you need to install xserver-xgl.
sudo apt-get install xserver-xgl
Restart X.
Phew. Now you should be able to see the four choices on the Visual Effects menu. Choose Custom. Click on Preferences. You can play around now with the available options. If you want to the enable the 3D desktop cube, check for Rotate Cube. And don’t forget to set your workspaces to 4 columns and 1 row.
For 3D desktop cube — hold Ctrl+Alt, left click and drag.
To switch between tasks, the 3D style — hold the Windows key and press Tab repeatedly.

why not using slackwre?
SLACK is UN-BUNTU
I’m actually in the middle of downloading Slackware 12.0 DVD
I just want to give it a try as a virtual guest.
Hei hei… does the 3D desktop cube originally came from Linux? Cause I’ve seen such as this on windows. It’s a third party however.
But is it really useful, or is it just to make the desktop look cool (or rather, confusing)? Can I play movies on each of the screen independently?
Actually, compiz can be installed on other Linux distros, not just Ubuntu. Personally I found the cube has no practical purposes other than being cool. I do like the 3D task switching and the window wobbling.
