I finally got around to reinstalling ubuntu 12.04 (x86) on my computer and am having a whole slew of issues. Here are the main issues I am having in order of severity.
1) Random GTK (GUI?) crashes. Basically the screen suddenly goes black and I am brought back to the lock screen and have to log in again. So far this seems to happen more when I am doing something and the computer is not sitting idle, but I wager if I left it idle long enough it would do the same thing.
2) Cannot resume from suspend. I am using a laptop and when I close the lid and open it again the screen turns on, but its all black. The only way for me to get back to doing anything is to restart the computer.
3) Plymouth is using VGA resolution. Not the most severe of the issues, but something that still bugs me. I would like to get the random crashing solved first if possible.
At the moment, this is pretty much a fresh install. I have installed some applications, I installed gnome-tweak-tool, but read somewhere that that was causing a problem for someone so I deleted it.
My computer is an Alienware M15x. It has an nvidia graphics card and I have a feeling that is causing some of these problems. Instead of using the 'additional drivers' tool in ubuntu, I did this
to install the latest nvidia driver.
