Fell free to propose other known Jaunty Jackalope bugs to be listed here but think to provide a link to the workaround and a link to the corresponding launchpad entry.

BUG:
====
Installing the 64bit version of Jaunty I found the install would just hang at the splash screen(ok for 32bit which was odd).
Found that as I did not have a floopy drive installed, the install would continual check for fd0

WorkAround:
==========
Disable the floppy drive in the bios.

The permissions of the /dev/nvidia files cause errors when processes are launched with non-root privileges on my 64-bit 9.04 desktop system.

In my case I get Direct Rendering errors when launching a Direct Rendering enabled VM inside VMware Server, but running glxinfo without sudo shows the error:

NVIDIA: could not open the device file /dev/nvidiactl (Permission denied).

I have found many other posts with the same issue (including people using Wine), and here is my current workaround since reinstalling the 180 driver package did not fix it:

gksudo gedit /etc/rc.local

Add the following before "exit 0":

chmod 666 /dev/nvidia* &

Launchpad: https://bugs.launchpad.net/ubuntu/+s...80/+bug/370249

Camera doesn't mount when connected and switched on.

Many people have reported this bug.
https://bugs.launchpad.net/ubuntu/+s...ux/+bug/301281

Quick fix:
Use the command:

sudo killall gvfs-gphoto2-volume-monitor

then connect the camera.

Long-term fix:
Prevent the process from starting. Use the command:

sudo chmod -x /usr/lib/gvfs/gvfs-gphoto2-volume-monitor

Remote Desktop (vnc) screen freezes when remote host is 9.04 although mouse clicks and key commands still reach the target machine.

The bug:
https://bugs.launchpad.net/ubuntu/+s...iz/+bug/353126

The workaround:
Disable Compiz on the remote machine
System -> Preferences -> Appearance -> Visual Effects = None

[BUG]-------------
https://bugs.launchpad.net/ubuntu/+s...ba/+bug/368273
When adding a printer attached to and shared on my Windows XP box with System->Administration->Printing, New->Network Printer->Windows Printer via SAMBA, Browse - you get right up to where clicking the little gray diamonds should reveal a networked printer and Poof the dialog crashes and is gone.

[WORKAROUND]------
Used the Windows box IP address instead of Browsing for the printer. This permits you to go to the next steps and create a printer, although it won't work yet, i.e. test page won't print. Next click the change URI button for the printer path name and it will present another opportunity to Browse. This time it will find the Windows printer, correctly changing the path and then the test page will print and the printer is setup.

I used this modified workaround. Maybe it's a little simpler for some of us newbies than figuring out the Windows machine's IP address.

Click Main Menu>System>Administration>Printing
Click New>Network Printer>Windows Printer via SAMBA
Hit the "Browse" button. "SMB Browser" box pops up. Note the names under the headings labeled Share and Comment. (So in my case, the name under Share was MSHOME and the name under Comment was DESKTOP1.)
Cancel out of the "SMB Browser" window. Click in the entry box beside smb:// and enter those names in this form: ShareName/CommentName/
Click "Browse" again. This time the list should be populated in the "SMB Browser" popup box (after a short wait) with the names of your shared printers. Choose the one you want and proceed with the installation.

Bug: automatic updates checking not working after upgrade from Intrepid to Jaunty. `apt-get update` or update-manager 'check' works fine, however, but are manual operations.

Launchpad: https://bugs.launchpad.net/ubuntu/+s...er/+bug/356152

Reason: /etc/cron.daily/apt script incorrectly chmod'ed as 644 aka not executable

Fix: # chmod 755 /etc/cron.daily/apt ... reboot; might help to remove /var/spool/anacron/cron.daily

How is that a workaround?

Just when I was truly beginning to appreciate all that compiz had to offer. (80$ video card, 4 gigs of memory later).
