Dumping all monitor internal data.

stf92 · 08-12-2012, 04:01 AM

Hi:

I once ran a command which gave me a large amount of data inherent to the monitor (console output). For instance max dot frequency or the range of allowable vertical frequencies. But I can't remember its name. Could somebody tell me?

Kernel 2.6.21.5
Slackware 12.0

You can use get-edid and parse-edid but you will need to install this IDK if there is a slackbuild.
Have a look also at this

hwinfo might be what you're looking for. There's a SlackBuild for 13.37, but not 12.0.

Here's the output:

No, I'm speaking about a command belonging to the Slackware 12.0 distribution. I'm sure I ran it, but can't find anything with apropos.

brianL · 08-12-2012, 06:17 AM

Just a guess again.Try this:

Code:

xdpyinfo | less

stf92 · 08-12-2012, 07:36 AM

Not exactly. That was hardware information, as horizontal scan rates and bandwidth.

I could have been dreaming, but what I saw was more like in post #3. A modern display, as hard disk drive, has plenty of data stored in it, beginning by manufacturer name and model. If it was not a slack utility then I'll see if I can get the official hwinfo sources, given that 12.0 to 13.37 is too great a leap.

Perhaps what I did was printing one of the files in cat /proc/.

Celyr · 08-12-2012, 10:17 AM

If you have a nvidia card I think that there is an EDID reader built-in nvidia-settings
