I've been having so much trouble since I built this machine, Windows 7 had an issue where the monitors would randomly shut off for a couple seconds followed by a notice that the driver crashed. Got fed up and went with Linux in hopes things would be better, and I had been wanting to go with Linux anyway. Solved THAT problem but brought on many others. Running Xubuntu now (not sure how to check version but think it's still the latest) I'll start with the specs: - 12GB ram - Core i7 processor - 2x Nvidia GTX 560TI - Gigabyte X79 UD3 motherboard - SSD1: OCZ Vertex 3 (drive for Linux, primary used OS) - SSD2: Intel M4-CT128M4SSD2 (drive for Windows, rarely used) All the problems I've been experiencing so far: - If I try to use nouveau driver, screens constantly flicker like mad. The install process was quite brutal to go through since it did it then too. Any Linux live CD does not work properly on this system because of this insane flickering. Very hard on the eyes and just makes my blood boil. - Apps randomly crash with no warning. They'll just completely shut off and produce a "crash warning detected" notice. Sometimes it's daemons that I don't really notice that are gone, other times it's apps I have open. - Any music player randomly start to play just silence, or stop altogether, or crash - Cursor will get stuck in a way where I cannot click or do anything with it, but I can move it. Usually it will get stuck in the hand icon or other icon than the normal cursor. When this happens, I lose complete control of the keyboard so I cannot do anything. At one point I did not lose control of the keyboard so I was able to go to the console and close the offending app (usually Thunderbird or Firefox). But now when it happens I have no keyboard. Have to hit reset. The system itself is responsive when in this state as far as I know, it's just that I lose all ability to input so I cannot do anything with it. - Every time I reboot, my theme changes to some weird black theme. Not a standard one that I can actually pick. - my 3rd monitor runs in a separate X session (can't figure a way to get all 3 going at once without some very ugly workarounds) and often it will mess up. All sorts of weird artifacts on the screen etc. Need to reboot. And many other issues but those are probably the biggest I can think of now. I'm stating to think it's all related. Just now, I had minecraft start to get extremely laggy, then it shut off AND my music player (Gaydeleque) closed too! WTF is going on here? This is the output of dmesg. Out of memory?!?!?!I have 12 freaking gigabytes of ram, how can there not be enough memory for minecraft and a couple other apps? This particular issue is the first time it happens though. I'm at wits end here with this stupid system, wtf is wrong? I just want a system that stops acting stupid like this, what do I do? I really hate having to throw money at the problem but I'll do anything at this point. It's just so frustrating to deal with this crap.
