Re: [vox-tech] Acer AL2216W (blank screen)
So I following Richard's advice, I decided to replace the one component I could easily do: I borrowed a VGA cable from a neighbor and the monitor works! I was surprised. My old cable doesn't look crimped or damaged in any way, but whatever... it's a cheap fix. Actually, I sort of have mixed feelings about it. I had started to do some monitor shopping online and I was thinking, Christmas isn't that far away :) Thanks to all, Thomas On Fri, Sep 17, 2010 at 1:49 PM, Bill Kendrick n...@sonic.net wrote: FYI, we look to be having an Installfest next Saturday (9/25). ;) http://www.lugod.org/if/ On Fri, Sep 17, 2010 at 09:39:25AM -0700, Thomas Johnston wrote: The reason i would doubt that it is the graphics card in my laptop is that I cannot get an image to project to the external monitor even when I connect it to a different computer. snip However, it no longer detects the monitor connected to the VGA port.

No, the video card is in the computer, generating the image. If you see the monitor logo, then the problem is likely that no usable signal is arriving at the monitor.

Re: [vox-tech] Acer AL2216W (blank screen)
The reason i would doubt that it is the graphics card in my laptop is that I cannot get an image to project to the external monitor even when I connect it to a different computer. A few days ago I was able to use the monitor with either laptop, now I cannot get an image to project to the monitor from either laptop. It would seem unlikely to me that both laptops have failed graphics cards. However, I did the sequence of commands that you suggested. The Xorg.0.log file no longer shows the warning message I mentioned before: (WW) Sep 16 15:07:43 NVIDIA(GPU-0): Unable to read EDID for display device CRT-0 However, it no longer detects the monitor connected to the VGA port.

Re: [vox-tech] Acer AL2216W (blank screen)
In recent years I have noticed that video cards die distressingly soon. Often with strange symptoms that make it appear to be something more basic. I do have to admit that the most recen time (about two weeks ago) it was in fact the monitor. That was an HP 22 LCD monitor only 5 years old. My previous monitor was a Sony CRT that went back to the early 90's. I can only suugest that you try swapping out starting with whatever you can do cheaply.
