Turned On My Monitor To See What Looked Like a Kernel Dump
location: ubuntuforums.com - date: February 10, 2013
So I turned on my monitor today on my Ubuntu box had a black screen with what looked like a kernel dump of some kind. Lots of stack traces and call traces. Not sure, this has not happened before to me. Before I start testing all my hardware in my box right away, I wanted to get some opinions from the community. I found the message in /var/log in the system log that I had seen:
Basically just the "kernel:" messages. I recently installed cifs-utils (yesterday) so not sure if that has something to do with it. I am running Ubunto 12.10.

Is there a linux laptop that just works? monitor, hibernate, sleep :(
location: ubuntuforums.com - date: September 27, 2012
I dreamed of a linux laptop that just worked. I got the latest gazelle professional. I was a fool.
1. It does not hibernate. That's fine. I should have read the page more carefully. It should have been clear from the feature list explicitly mentioning suspend that I wouldn't be able to hibernate.
2. If I plug a monitor in via HDMI, I get really high kworker cpu usage and the mouse is really really laggy.
3. It often wakes from sleep with a black screen. I have a functioning mouse cursor, but I can't see the desktop. I resort to switching to a terminal(ctrl-alt-f1) and restarting the desktop manager. Losing everything I was working on and defeating the purpose of a sleep function.
Is there another offering from system 76 not be plagued with linux issues like this?
4. This is unrelated to linux: I got a matte display because I didn't like reflective glossy displays. For some reason the frame around the display is a glossy and reflective surface.

I'm not sure if this is in the right area but i have a question. Could someone explain to me how to setup any version of linux so that my 1366x768 resolution to run. right now the only way i can do that is to connect to an external monitor source. It boots and all but i cannot see login screen and i can't see the desktop without using external monitor which can be seen when using the external monitor to login. i was just wondering if there is a way that i can get this pc to just run otherwise because i honestly would prefer to run linux than windows 7 which is currently what i am running. i will probably run ubuntu because it just works.
4 monitor setup, configuration problems
location: linux.com - date: August 5, 2010
We have installed Linux Mint Isadora on a Dell Precision 490 desktop workstation. The video card is an nVidia Quadro NVS 450 and we have hooked up four monitors to it. We want a 2x2 layout with the 'master' monitor being the one on the bottom left. By 'master' I mean that should be the one with the menu bar. But we can't get the xorg.conf to make it work that way.
Suboptimal configuration 1 = All four screens are X-screens, Xinerama enabled, TwinView disabled, and the top left screen is the 'master.'
Suboptimal configuration 2 = The bottom two screens are a pair in Twinview, and the top two are another twinview pair, and xinerama is enabled. The bottom screens are the 'master.'
Suboptimal configuration 3 = same as #2 but in a 1x4 layout (all four monitors in a row).
What we want! = 2x2, Xinerama enabled, no TwinView, bottom left = 'master.' Our xorg.conf for this is pasted below. But when we try to drag the mouse to either of the upper screens, it goes all buggy. Is this a screen co

RHEL 6.3 Display preferences: Monitor Unknown
location: linuxquestions.com - date: March 7, 2013
I've been struggling with this problem for weeks to no avail.
When I go into Control Center-> Display Preferences my monitor is no longer recognized.
Instead, there is a red box which says "Unknown".
This one problem is preventing me from doing just about everything I need to do my job including setting up multiple windows, using an extra VGA plug in monitor, changing screen resolution.... running X -configure, you name it.
Is there any way to reload the video card drivers in Red Hat Enterprise so that it can detect the monitor?
The only utility I've found that might help is one called system-config-display, but that apparently has a bug and won't run, no matter how many times I've reinstalled.
Anyone ever encounter this before and fixed it?
The weirdest thing about this is.... the monitor WAS recognized when I first got the laptop, now it appears to have forgotten it.
Thanks much for any help.
how to use external monitor as extended workspace?
location: ubuntuforums.com - date: August 9, 2011
I have just installed Xubuntu on my MacBook. I have an external monitor which I use as extended workspace. When I plug it in, nothing happens, but I can activate the monitor in the system settings. The problem ist that my MacBook screen is mirrored onto the other screen, which is fine for beamers but makes no sense with external monitors. There's no option to use the monitor as exptended workspace.
How can I make this work?
It's an Acer monitor, BTW, if that's important, and I'm running Xubuntu 11.04 (just downloaded and installed yesterday) on a MacBook 4.
Edit: SOLUTION: It easily works with URandR (sudo apt-get install urandr), a GUI to RandR. But URandR doesn't like Compiz, setting up a virtual screen of the right size fails if Compiz is running. The solution: Disable Compiz (xfwm4 --replace), then set up the virtual screen with URandR, and then turn on Compiz again (compiz --replace). Once the virtual screen is set up, there doesn't seem to be any problems with Compiz anymore.

any info can help or even just a point in the right direction, and yes before you send me a link i have googled it.
