Re: 12.04LTS / Win XP Dual Boot (32bit) Problems after RAM upgrade
Wow. Lots of issues from a RAM upgrade. Let's start at the beginning:
Make sure that your RAM modules are absolutely identical, that they are in the proper slots (your mobo docs will tell you in what order they must go) and that they are seated properly. This last point is often the cause of so much grief. Reseat them to see if things improve.
What version of XP are you running? Home versions were deliberately hobbled to see no more than 4GB, although it shouldn't crash simply because you have now installed more. As a side note, XP will reach end of life in 7 months, after which you are unprotected against any further exploits that bad guys are continually uncovering, so plan accordingly.
We don't know if your PS is problematic, but before suspecting it, let's look at other possible issues first. For one thing, it is not underpowered for your setup, unless you have other components that you are not mentioning. Also, because you initially installed Ubuntu 32-bit with 4GB of physical RAM, it may not have installed the PAE kernel, which would be needed to address more than 4GB. This is easily checked by doing:If it shows all of your memory, then you already have the PAE kernel. If it only shows 4GB, then you have two choices: you can switch to the PAE kernel or you can install Ubuntu 64-bit. Without knowing more about your apps and setup, my initial recommendation would to go 64-bit. I don't even know why Ubuntu keeps recommending the 32-bit OS. This is now old technology and should be reserved only for 32-bit limited systems.
With respect to the Launcher, it may be more trouble that it's worth to try "fixing" it, especially when it is so easy to just re-create the icons and be done with it.
Thanks for giving me a chuckle. Since XP will shortly be EoL I would like to make a suggestion. You don't mention your CPU, but given your mobo, I would hazard a guess that it is at least multicore. If so, then a way to solve both problems neatly is to run XP within a virtual machine (VM) like VirtualBox. This is how I run my XP. With your new memory upgrade and going to Ubuntu 64-bit, you easily have enough resources to manage this. That way, when XP is no longer supported, you can also cut its network connection to the outside world, sandbox it, and run it only for your CAD work. By confining XP to 4GB (or less) you will have a multitasking environment with your CAD app running inside XP running on a window in Ubuntu. Cool.
...I hate to ask this, but what about Windows?
