Some of Known ubuntu 9.04(Jaunty Jackalope) bugs with workarounds
Sponsored Link
1) Work around for Nvidia non-root permissions bug in Ubuntu 9.04(Jaunty)
Bug Details
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.
Workaround
Edit /etc/rc.local file from your terminal
gksudo gedit /etc/rc.local
Add the following before "exit 0":
chmod 666 /dev/nvidia* &
Save and exit the file
2) Camera doesn't mount when connected and switched on in Ubuntu 9.04(Jaunty)
Bug Details
Camera doesn't mount when connected and switched on in Ubuntu 9.04(Jaunty)
Workaround
Quick fix:
Run the command from your terminal
sudo killall gvfs-gphoto2-volume-monitor
then connect the camera.
Long-term fix:
Prevent the process from starting Using the following command
sudo chmod -x /usr/lib/gvfs/gvfs-gphoto2-volume-monitor
3) Remote Desktop (vnc) screen freezes when remote host is 9.04
Bug Details
When using the nvidia-restricted driver and compiz desktop effects the vnc server will not refresh the screen. This is being caused by the xserver not getting "damaged" by the nvidia-restricted drivers.
Workaround
1) Disable Compiz on the remote machine
System -> Preferences -> Appearance -> Visual Effects = None
2) Install x11vnc using the following command
sudo apt-get install x11vnc
use this command in the terminal
x11vnc
--noxdamage--passwd XXX -forever
4) Ubuntu 9.04 Blind to XP's Shared Network Printer
Bug Details
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.
5) wubi installer's pyrun.exe says "no disk"
Bug Details
Wubi repeatedly complains "no disk" with "Cancel, Try again, Continue" on some systems with card readers
Workaround
One work-around: Use Windows' "Safely remove hardware" to disconnect card reader and try again
Another work-around: Bypass Wubi and install Ubuntu into its own partition
6) mdadm software raid breaks on intrepid-jaunty upgrade
Bug Details
Upon upgrading from Intrepid to Jaunty, my software RAID5 array did not mount.It appears the problem may have been caused by /etc/mdadm/mdadm.conf being silently overwritten by a default config file.
Workaround
After executing the following in a recovery shell, the array mounts just fine.
mdadm
--examine--scan--config=mdadm.conf >> /etc/mdadm/mdadm.conf
Or you can auto create a new mdadm.conf file by uninstalling mdadm, re-naming or deleting mdadm.conf, then re-booting, re-installing mdadm, and run this
sudo mdadm
--assemble--scan

I hope this will be useful for some users.
..And the sound issues! Almost all the time, when playing something with sound, the app crashes or hangs, or the sound just disappears…
@Emil There are multiple causes for that symptom. The culprits lie in linux, alsa-plugins, and pulseaudio. While “working around” the problem by removing/disabling pulseaudio is a “solution”, it is not a fix.
See bug 345627.
What about this bug?

Ubuntu folks needs to fix these bugs with an update ASAP. Many fear the terminal or know enough to find a windows IP address to get the printer to work.
Leaving problems will cause new uses to stop trying Ubuntu.
@ Bill
“Leaving problems will cause new uses to stop trying Ubuntu.”
If you think there are to many bugs… then why use the beta instead of the long-time-support version 8.10 or so.
New users should not start with a beta version, i would not recommend it.
Good to know the vnc refresh is a bug, thought i did something wrong in the configuration 😛
I know a little to keep stuff going. But many do not care about the terminal, etc. They just want it to work without hassles. I have two kids and a wife that only want ubuntu to work. That is what dell is selling 8.04 with codec, etc out of the box few problems.
Not saving wifi passwords and keying. What a poor feature. Must be some programmer showing off a case of stupidity…LOL
Keep it simple if you want mass appeal.
There should be an option to store permanently or not when you first connect to the wifi. And in the menu’s a way to switch back and forth with a few key stroks.
Better yet, every time you see a password menu, the option for storing permanently or not should be a button click away.
I’ve tried the workaround on the printer issue about 5 times now, and still can’t print.
Go to the xp machine…
Start>Run type in “cmd” without quotes for the dos box
type in “ipconfig /all” without the quotes
Look for the ip address of your machine. Mine is 10.1.2.108
Go to the ubuntu machine
Where you browse for a printer in samba type in
“10.1.2.108/printer” without quotes.
I think that is it…
8.04 is so easy to setup a printer on a xp machine. Why is ubuntu no on top of this and fixing it? Ubuntu has to be simple to kick windows in the butt.
Mine printer works above but it is connected to linksys router. It could make a difference.
You have to go to the xp box and right click on the priter you want to share and make sure the printer is in share mode. A hand will be under theh printer if it is a shared printer.
I tried the nvidia fix (after installing the nvidia driver from the non-free driver menu). It gave me the error that /dev/nvidia* doesn’t exist. I definitely know that they’re nvidia cards–I installed them myself! (yeah, they’re SLI)
Hi there,
just wanted to say i have not had any issue’s with upgrade to jaunty BUT i have lost some disk space
with my previous install i maintained a constant 1GB free space in / this included the rotated log files etc as well as 1200ish installed apps including webmin/apache/mysql/ntop/cacti/mediatomb
since upgrading to jaunty i can only maintain a constant 529Mb freespace in /
i have removed unnessecary apps such as games/office apps/tomboy & i have also changed the rotation of log files BACK to 4 day’s as the upgrade changed them to 10 or 7 days
i have used the 2 cleaner app’s trash collector & computer janitor which removed ALL unneeded configs from updates,orphaned libs, unused lock files and any other chuff that was no longer needed but all that this managed to glean was a messley 50MB between them
have any of you readers out there noticed a jump in the installed system footprint?
my /usr/lib folder is the largest on my system currently at 126Mb
I know my question might sound quite stupid, but I’m not that much into ubuntu yet. Why doesn’t anyone just fix these problems when they are known anyway, and when have workouts? That is one of the brilliant things about open source. The source code is open so everyone, who has some programming knowledge and some time, can fix erros and thus there’s fewer errors in linux compared to windows.
Getting my wifi to work on Dell Latitude D610 has been a great struggle with no success yet. I have an Intel pro/wireless 2200BG wireless card and no matter what I do, Ubuntu just doesnt recognize it. There seems to be a problem because as soon as I install Ubuntu 9.04, my wifi works for a while and then the computer hangs. Once I restart the computer, wifi option is gone and there is no way to get it back. Trust me, I have spent hours on Ubuntu forums and there is no fix for this.
I have to add that 9.04 is more buggy than 8.04 – the version from which I just upgraded – ever was. I’ve had to deal with ghost reboots, green fuzzy screens that are only solved with a hard reboot, sound card issues (sorry, I don’t remember what finally fixed them), and an incessant memory leak that is driving me nuts. I also do not understand why ctrl+alt+backspace no longer restarts x-server. I have a Dell Latitude D620.
Hello,
I’m running Kubuntu 9.04 and the camera-fix doesn’t work for me since it seems there is no gvfs-gphoto2-volume-monitor process. Have any ideas on how to work around the problem running KDE?
To: Tomas: (June 14, 2009 at 7:18 pm)
I have a HP M-307 camera.
I set the device to Digital camera – not USB disk drive, then i run:
/usr/lib/gvfs/gvfs-gphoto2-volume-monitor
from nautilus and then switch the device is on.
It`s work fine for me.
(And sorry my bad-bad English:)
Just installed Miro 2.0.3 using Synaptic Package Manager (it gathered and installed several dependencies) in the 64-bit version of Ubuntu 9.04. Browsing the catalog, I clicked Watch on some of the titles, which brought me to the blue-green page with menues but no video playback. I clicked Watch in browser, which opened a tab in Firefox 3.0.11 with a black video screen and low-volume audio. Video card is Sapphire HD 3870 ATI. Everything but Miro works great. I’m also using the actual versions of Java and Flash, not the gnu freewares.
I have seen Ubuntu 8.10 advised for N00bs (me) but for the life of me I cannot get the download places to offer me anything but 9.04 or 8.04. Can I get a link to DL the iso for 8.10?
Hello a friend of mine is having a problem mounting anything USB on Ubuntu Jaunty (It does not mount his Cell PH (Sony Ericsson W380), Digital Camera (Benq), etc. could you give me a hand about this?
thanks!

thanks!
@ Jose
opent a terminal and do
sudo apt-get install usbmount
that should work (it does with debian)
So far I’m unimpressed with Jaunty Jackalope. It has created more problems than it has solved, my latest problem being Wifi and networking no longer functional.
I’m about ready to give up on Ubuntu as being anything more than a science project by college students and disaffected programmers.
It’s clearly not at the level and apparently well never arrive at the level of being a professional plug-and-play OS.
I spent hours looking for an answer to the camera problem. I finally found a solution, but it took several tries to work and only worked once. I find this article, now my camera works every time. THANK YOU!
Regarding the problem connecting to a windows printer share…
9.04 (Jaunty) shipped with a beta hp driver. Perhaps the same is true for some other brands. When I discovered this and upgraded the driver, everything worked as expected.
URL for HP Linux drivers is: http://hplipopensource.com/hplip-web/index.html
I have two ubuntu in my laptop, ubuntu 8.04 and ubuntu9.04. Ubuntu 8.04 work very fine but Ubuntu 9.04 is bad ( Kubuntu 9.04 is no better ). I think this can be happened because Canonical try to be cutting edge. I hope next time Canonical will be more conservative, just release products who stable and work out of the box although they are rather old,
wow, thank you so much for that raid fix; worked perfectly. I was about to throw my computer out of the window
Thanks. Now my VNC is working again.
By the way, why is it necessary to install x11vnc? Because I just disable the Compiz and works for me.
Thanks! My ubuntu vnc works now 🙂
