I have a Logitech diNovo Edge Bluetooth keyboard. I like it a lot for use with our HTPC. However, I found that when the HTPC is suspended, the keyboard would not reconnect on resume. I found this solution on the Ubuntu Forums and it works for me. Edit /etc/default/acpi-support to remove and reload the Bluetooth module on suspend and resume: # This will save less power, but may work on more machines #ACPI_SLEEP_MODE=mem ACPI_SLEEP_MODE=standby # Add modules to this list to have them removed before suspend and reloaded # on resume. An example would be MODULES="em8300 yenta_socket" # # Note that network cards and USB controllers will automatically be unloaded # unless they're listed in MODULES_WHITELIST MODULES="i8042" # Add modules to this list to leave them in the kernel over suspend/resume MODULES_WHITELIST=""

I was surprised to find out that plugging a DVI to HDMI cable into my Lenovo X220 docking station allowed me to use the audio channel of the HDMI connection. However, setting it up required a bit of trial and error. Open your sound settings and click the "Hardware" tab. You can then choose a "Profile" from the drop down. There are lots of profiles to choose from and many of them mention HDMI. For me, somewhat inexplicably, "Digital Stereo (HDMI) nr 3 Output" is the correct one. To verify that the chosen profile is the correct one, click the "Test Speakers" button. I found that it can take a few seconds for the profile selection to take effect. So count to ten before testing.

I've used my beloved Kinesis Advantage keyboard for over half a decade. Occasionally, I've had the issue that Eclipse stops responding to the F3 key for opening declarations. After checking all the key settings, I found that Eclipse was correctly configured. That lead me to use xev where I found that the F3 and F4 keys were behaving differently than the other function keys. Resetting the keyboard memory ( Program+Shift+F10 ) had no effect. Resetting it completely (holding F7 while plugging the keyboard in) also had no effect. Strange. Finally, I found the answer on the Kinesis FAQ . My F3 and F4 keys were behaving like multimedia keys (see manual to configure these). This feature can be disabled by holding = and pressing P for PC (you can also use W for Windows and M for Mac).

I just discovered 'rename' today after briefly considering writing it myself. Here's the gist of it: rename [ -v ] [ -n ] [ -f ] perlexpr [ files ] So, for example: rename 's/(.*?), (\w+)/$2 $1/' *.avi Changes a bunch of videos from "World Is Not Enough, The.avi" to "The World Is Not Enough.avi" Hooray!

I just discovered today that journalling was not enabled on my Macbook Pro. I can't fathom why it isn't enabled by default. Take a look at Applications, Utilities, Disk Utility and click 'Enable Journalling.'

An ISO is a file that represents a CD. It contains all the data needed to recreate the CD it was copied from. You can burn this image to a CD or "mount" it and access it from "virtual" CD ROM. To mount the image, use DAEMON Tools. You can download DAEMON Tools here . Install DAEMON Tools. DAEMON Tools will add a new virtual CD ROM drive. Right-click the DAEMON Tools icon in the system tray. Select Virtual CD Rom, then Device, then Mount. Select the ISO image you downloaded. DAEMON Tools will load your ISO into the new virtual CD ROM it created. Now, you can access the virtual CD ROM just like you would with a normal CD.
