I've been running Ubuntu 8.04 on my laptop for the longest time without much problems, so I figured to beat the download rush and upgrade my desktop.
Unfortunately, it didn't quite go as smoothly as I hoped.
1) Hard trouble setting the resolution and force the use of the nvidia driver to enable 3D acceleration. The quickest fix is to install the envyng-gtk2 package.
"sudo apt-get install envyng-gtk2"
"envyng-gtk2"
This program is actually a wizard that will automatically downloads the driver for your ATI/nVidia card.
2) Flash keeps crashing. The temporary fix is to uninstall libflashsupport:
"sudo apt-get remove libflashsupport"
Unfortunately, this library is needed to get flash working w/ PulseAudio. So hopefully, this will be fixed soon.
3) KVM module enabled by default. VirtualBox apparently does not want the KVM module to be enabled.
The easiest way to fix this is to blacklist it:
"sudo vi /etc/modprobe.d/blacklist"
Add "blacklist kvm" on it's own line.
For intel users, also can't hurt to also blacklist "kvm_intel"
You can then unload the module by executing
"sudo modprobe -r kvm_intel" (for intel users)
"sudo modprobe -r kvm"
This allows you to unload the module without rebooting.
4) Hardy by default will not share printers. While upgrading, it will alert you for a new cupsd.conf file that only listen to localhost. I used the maintainer's version anyways since I didn't have any custom options set.
In order to share any printers:
-Open System->Administration->Printing
-In Server Settings, make sure "Share published printers connected to this sytem" is checked. This is a global share option for all your printers. For those upgrading, this will probably be unchecked and the only thing that needs to be changed.
-Under Local Printer, select the appropriate printer
-Goto the Policies tab
-Ensure that Shared is checked
Save and you're done! This will overwrite the cupsd.conf file so it will listen for any ip address.
5) I had to upgrade Adobe Acrobat (acroread) from the medibuntu repository, otherwise it will crash right away. Check http://www.medibuntu.org for instructions on how to add the repository.
That's it for now... I'll post more if I come across it.
