[SOLVED] Switch screen resolution and also a small problem with the system doing a meltdown

[pottzie]

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.

i would try running memtest to check if your new memory is any good.

Which graphics card/chip and which driver are you using? Most recent monitors should be
run at their native resolution, which should be detected by the X server and driver via EDID.

Take a look at the /var/log/Xorg.N.log(s) to see how the display is being detected and configured.

Running xrandr in a terminal will give you basic information like current and possible resolutions.

yeah, it was a bad memory card. the new one works, my old memory was bad, and the new one just kinda made the problem worse.


Solved!
