Any of the Ubuntu Distros are fine. Ubuntu with Unity looks nice, but can be confusing to use. If your coming from XP, I think Kubuntu, Xubuntu, or Lubuntu would be better. It also depends on what...

I had the same problem, locks up when restarting or shutdown. I even reinstalled Ubuntu 12.04 and still did it even with open source video drivers. I am now using Xubuntu 12.04 and so far have no...

After searching google some more I found this (Sudo DISPLAY=:0 aticonfig --pplib-cmd "get fanspeed 0") and it displays this (Fan speed query:
Query Index: 0, Speed in percent
Result: Fan Speed:...

I looked there. It doesn't display the current clock speeds or fan speeds.

I installed the proprietary drivers after a clean install of Ubuntu x64 12.04. I have an ATI Radeon HD 4670 video card.

How do I check the fan speed and clock speeds under Ubuntu?

The printer won't show up unless you install the drivers from that site I posted earlier. Canon uses bjnp:// then ip address.

Weird. I can print web sites and text documents. I can scan. But I...

Great replies, thanks for answering all my questions. Have fun.

Thanks for the information. Wasn't sure about security because of the opensource. I didn't know if anyone could take the source code and create a security flaw. If its more secure than Windows...

I use 64bit and seems to work ok. Haven't tried 32bit since I have a 64bit cpu and 6gb of ram.

I guess if you don't know what you have, use 32bit. If you know you have 64bit cpu then choose...

Does Wobbly Windows work in regular Ubuntu 12.04 with Unity too? I am hesitant to try it until I know it should work without crashes first. I am fairly new to Linux and really don't know what to do...

Mine locks up on shutdown sometimes. I think its related to the video driver and 3d Unity. I read that if you logout first then shutdown, it works. I tried it and works for me.

I made the switch today from Windows 7. I always found Linux interesting and wanted to learn it. Now that Ubuntu is more user friendly, I will be using it and learning it slowly. I did run into...

That sucks. I tried searching for how to install in 12.04 but cannot find any info. I wonder if the bug will be fixed. At least Windows 7 will print for now.

I also found this message. usr/lib/cups/filter/pstocanonij failed

Have no idea what that means.

I go to print anything and nothing happens. If I watch the status, it says idle then when I goto print it says failed to read side channel request.

Yes, reinstalled printer.

Yes, has fixed IP.

Yes, can ping IP of Printer.
