Q I want to try Ubuntu, but I'm worried about the valuable pictures, documents, music, and videos on my computer.
A Before you do anything, go and buy an external drive, and copy all your valuable files onto the external drive. Or buy a spindle of DVD-R discs, and burn copies of your files onto DVD.
Q Where can I find information about what's going on when Ubuntu boots?
A http://upstart.ubuntu.com/cookbook/
Q If I do gksudo nautilus in 12.04, the desktop background changes from what I have selected to the Ubuntu default wallpaper, and the file manager is then handling drawing of the desktop.
A Try: gksudo 'nautilus –no-desktop'
Q I'm not getting any sound from VLC in Mint 12. All the other sound apps work fine.
A Open VLC, select Tools, Preferences, the Audio tab. For “Output module,” select ALSA. For device, select the appropriate one. Click on Save and close the window. Or, run software manager and install the VLC “pulse” plugin.
Q The boot process stops at a screen that says “40GB drive missing. Continue to wait or press S to skip mounting, or M for manual recovery”. How can I stop this message from appearing?
A (Thanks to audiomick in the Ubuntu Forums) Open a terminal and enter this command:
gksudo gedit /etc/fstab
Find the line which includes “40GB” and turn it into a comment by inserting a number-sign as the first character. Save the file.
Q When I run Disk Utility, I get the message, “The partition is misaligned by 1024 bytes. This may result in very poor performance. Repartitioning is suggested.” I have a new “Advanced Format” drive.
A Use the latest GPartEd Live to partition the HDD to the nearest MB. The partition needs to begin on a 4K boundary, which is 8 of the old 512-byte sectors. It really does affect system performance.
Q I have a Lenovo laptop. The function-keys default to controlling brightness, volume etc. I would rather have them be F1, F2 etc.
A To change this in the BIOS, see this page: http://forums.lenovo.com/t5/ThinkPad-Edge-Knowledge-Base/Fn-Fx-remapping/ta-p/237588
Q Can I use Skydrive from Ubuntu?
A Yes, there is a web interface which allows dragging files into Skydrive, and you can download from Skydrive. You will need a Windows Live ID, such as a Hotmail account.
Q I have a Belkin Components F5D8053 N Wireless USB Adapter v3000, and when I upgraded to 12.04, it doesn't connect to my wireless router.
A (Thanks to Chili555 in the Ubuntu Forums) Open Terminal, and enter this command:
sudo modprobe rt2800usb
When that works, add the driver permanently with these commands:
sudo su
echo rt2800usb » /etc/modules
exit
Q I am trying to use Remote for VLC on my Android phone, but I get “connection refused.”
A (Thanks to Steve Beresford) You need to edit VLC's “hosts” file, to include the IP address of your Android phone:
gksudo gedit /etc/vlc/http/.hosts
Q I have the Nvidia driver 295.40 installed in Ubuntu 12.04. Using Banshee, video playback stutters randomly and uses about 50-60% of CPU, and VLC is even worse.
A (Thanks to Christopher Suttles) I ran:
sudo apt-get install vdpau-va-driver vainfo libva1
CPU usage is the same with Banshee, but video playback is now flawless.
Q Is there a weather applet for Ubuntu 12.04?
A Yes, install indicator-weather from the software center, then run it. Provide your location and other preferences the first time you run it.
Q Please give me step-by-step instructions on how to connect my Beagleboard to my Ubuntu computer using an ad-hoc wireless connection.
A Step one: go to the Google web site 2. search for: ubuntu ad-hoc wireless network
3. go to the first link: https://help.ubuntu.com/community/WifiDocs/Adhoc
