1) Work around for Nvidia non-root permissions bug in Ubuntu 9.04(Jaunty)
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.
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)
Camera doesn't mount when connected and switched on in Ubuntu 9.04(Jaunty)
Run the command from your terminal
sudo killall gvfs-gphoto2-volume-monitor
then connect the camera.
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
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.
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
--passwd XXX -forever
4) Ubuntu 9.04 Blind to XP's Shared Network Printer
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.
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"
Wubi repeatedly complains "no disk" with "Cancel, Try again, Continue" on some systems with card readers
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
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.
After executing the following in a recovery shell, the array mounts just fine.
--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
