Xorg.conf monitor bug.

[wyzguy]

Please run the following commands.

1. ddcprobe | grep -i range
2. cat /var/log/Xorg.0.log | grep -i ranges
3. cat /etc/X11/xorg.conf | egrep -i 'horiz|vert'

The horizontal and vertical min-max ranges are different for each monitor.
The ddcprobe output and .log output on mine match fine.
The vertrefresh range from xorg.conf is not correct.
Important. Xorg.conf info overrides the correct info in the .log file!
Mine shows 59-76 which does match the comment dated 111029 at the top
of the xorg.conf file. Check out your specs on your computer.

This was on Upup 3.8.4.2, but applies to most (all?) recent distros.
It is probably a xorgwizard bug. This should be confirmable by others.
Thanks

this is what I get on Slacko 5.3.1. Guess this confirms it used to work.

After having changed xorg.conf manually without success I have used xorwizard and now screen is without displacement

Confused?
I don't care.
I like my no more displaced screen.
Thank you

Release Date: 19 April 2007

Have a newish widescreen monitor at the moment, which already has some little displacements in the bootconsole very likely because of the kernel and not only Xorg. The other much older LCD monitor i have does not even work with ddcprobe sometimes on 3.x kernels . Additionally, ddcprobe many times has to be run twice, as the xorgwizard and xwin scripts do it, to present output.

..this modeline almost gives edge-to-edge display on my CRT (it's shy maybe 5 pixels both sides horizontally). The next step to reduce width (1340->1344) throws my display to ~75% screenwidth with an inverted h-pincushion effect.

On less recent pups I never had to correct display offset with a custom modeline (racy 5.4.91 is another with offset issue on my hwr).

I would next try commenting out HorizSync and VertRefresh in xorg.conf, save it and reboot. I just found out that changes made to xorg.conf are persistent. They didnt use to be.

Oh, do a xrandr >1.txt from the terminal command line before, and after rebooting do a xrandr >2.txt. Then they then can be compared.

I gained 1 new resolution line and 3 new refresh rates.

Karl,
The request I made on Feb. 25 in the REQUESTS subsection gets its edid from the kernel at boot time. In other words, it does not use the edid from get-edid (won't run on mine) or ddcprobe which does not create an edid file.
I think it needs checked out to see if is a more reliable solution. Could you create a tiny bash script to scan that directory structure and if the file named "status" shows "connected", then redirect the file "edid" into edid-decode for output. Also edid-decode would need compiling, removing debug info, creating links?, and making it a pet. You would need to print out the card number and output connector name from the next higher up directory also.

Thanks

[Karl Godt]

wixguy, I think that ddcprobe could work, at least it does for me in sakura/vte terminal -
BUT NOT in the kernel console nor in traditional xterm console . And the kernel console is the one that is needed.

I have no idea why .
Thats why there is 'xorg.conf.' :

Short snap about the displaced bootscreen of mine.
Sometimes half a letter is beyond the left edge, this time two letters swallowed.
