I installed some extra memory and a different monitor. The new monitor is a wide screen, and comes up with a dialog box saying that I should set the screen resolution to 1366 X 768, and of course that can't be done from a GUI. But I'm also suddenly and strangely having the entire system "freak out," it logs out and logs back in suddenly and without any reason that I can see, I'm getting warnings that Google Chrome, X-11, ALSA are reporting errors. I've run an update, but I'm still getting the log-out, log-back-in thing. I tried to post to the forum from the computer I'm having the problem with, but after typing a sentence, it would freeze, or loop back into the login/logout sequence. It was working before, but I have Windows 7 installed in a VirtualBox set up, and Win7 was really slow, so I went for more ram, and had to change the monitor when mine was donated to my kid.
If anyone wants me to do anything like run tail dmesg, I'll try but it doesn't look like my box will be very cooperative right now, so it may be a problem.
