Description Bryan Cebuliak 2008-01-08 02:03:32 UTC 
System: Debian Sid 
Package: xserver-xorg-video-ati
Version: 1:6.7.197-1
Description: Using an old 15" TFT-LCD  monitor reporting correct EDID
version 1.0 information as per ddcprobe a manual edit of xorg.conf is
required. Otherwise resolution is wrong rendering the GUI unusable
especially with KDE  and KDM or GDM login.

Advice given in XStrikeForce about ModeLine entry in Monitor section
is incomplete, only forcing proper graphic size. A DisplaySize entry
must be included as well in  the Monitor section or else fonts are too
large in GDM login and KDE.

The ddcprobe gives correct  EDID information, but xdpyinfo and xrandr
do not concur as they do with the previous xserver-xorg-video-ati
version 1:6.6.193-3. Instead they report ridiculously incorrect
dimensions.

Below are the results of ddcprobe and  xdpyinfo/xrandr before and
after "upgrade". The correctly working xorg.conf is listed last.

This need for manual configuration using hardware correctly reporting
EDID is an unacceptable regression. Please fix.

Comment 1 Roland Scheidegger 2008-01-08 06:27:26 UTC 
Still looks to me like the EDID data from your monitor is bogus. It wouldn't be the first which has the size correct (in cm) in the basic display information block, but fails to provide the correct value (in mm) in the detailed timing blocks. Though that's assuming that EDID 1.0 even has that information (EDID 1.1 certainly does).
Comment 2 Alex Deucher 2008-01-08 07:22:39 UTC 
Please attach your xorg. It looks like your monitor has a bad edid.

Attached please find my Xorg.0.log and xorg.conf
I do not understand exactly what in the EDID 1.0 output makes you say
the EDID is "bad". There appears to be display dimensions in cm and
timing data on the ddcprobe in a similar way to my  other system's
newer monitor using EDID 1.3.  Why can not the xorg ati server cope
when it did before randr and it does now only with manual editing of
xorg?
Your bleeding user,
Bryan

I do not know if the correct information is in  the detailed timing
blocks. That is why  I  have  sent my  logs  and ddcprobe and  xrandr
probes  to you programmers to decipher. However, if the driver now so precariously depends on inconsistently formated hardware display information yet the correct size information in cm is still there as you say. Why  don't you adapt the driver software accordingly?
Comment 7 Bryan Cebuliak 2008-01-09 12:18:28 UTC 
This issue is not isolated to my old monitor or my ATI graphics card as you know. It is part of a rather large regression of function I think related to the change to Randr.  
Similar bugs are previously reported for example in  Ubuntu and upstream on Intel drivers.

Comment 8 Alex Deucher 2008-12-03 01:06:49 UTC 
Is this still an issue with a newer xserver?  It should handle broken edids better.

I can confirm that this issue still exists in the following configuration:

- On-Board Radeon chip; lspci info:
   01:05.0 VGA compatible controller: ATI Technologies Inc Radeon HD 3200 Graphics
- Monitor: Samsung SyncMaster 2333SW (vendor "SAM", prod_id 1246)
- radeonhd driver 1.2.5
- xorg-server 1.6.1.901 (from experimental)

* Symptoms

- ddcprobe shows correct dimensions: "screensize: 51 29"
- Xorg seems to know proper size (from Xorg.0.log):

(II) RADEONHD(0): Max Image Size [cm]: horiz.: 51 vert.: 29

- But later it somehow comes up with incorrect numbers, which
  propagate into xpdyinfo:

(II) RADEONHD(0): clock: 138.5 MHz Image Size: 477 x 268 mm

- xdpyinfo:

  dimensions: 1920x1080 pixels (477x268 millimeters)

- xrandr has the wrong numbers as well:

  DVI-D_1 connected 1920x1080+0+0 (0x3d) normal (normal left inverted right x axis y axis) 477mm x 268mm

I tried adding the monitor to quirk_detailed_use_maximum_size(), but
that didn't change anything.
Comment 10 Bryce 2009-07-16 00:21:22 UTC 
I'm getting basically the same thing with

X.Org Server 1.4.2 11 June 2008
ATI Technologies Inc RV280 [Radeon 9200 PRO] [1002:5960] Card
Shuttle X17 Monitor.

By messing with xorg.conf I can get it to a video mode that produces tearing (rather than so far out of sync the monitor bails).  But not to a working setup.

This is a different issue.  Please file a different bug and attach your xorg log and config.
Comment 13 Alex Deucher 2010-10-19 16:09:15 UTC 
not a driver issue.
Comment 14 Adam Jackson 2018-06-12 18:44:28 UTC 
Mass closure: This bug has been untouched for more than six years, and is not obviously still valid. Please file a new report if you continue to experience issues with a current server.
