Description Wolfgang Knauf 2006-02-26 19:32:50 UTC

Sax2 created invalid modelines in xorg.conf for my Highscreen MS1795P CRT (17'', from 1998).
The vertical frequency for 1280*1024 became 81Hz while it should be according to the manual only 75Hz.

Problem is: NVidia driver 1.0-8178 used EDID to detect the valid resolutions for this monitor, found that all modelines were invalid and fall back to headaching 1600*1200@60Hz. This is the reason why I consider this problem "major".

I reported this first in the NVidia forum, see here: http://www.nvnews.net/vbulletin/showthread.php?p=822491 (you will find the relevant logs there). My first approach was to disable EDID detection in the driver, this did it. The NVidia guys suggested to remove all modelines and this made the NVidia driver work (used 1280*1024@75 Hz).

Below is the xorg.conf created by SaX2.

From the manual of the monitor:
Scanning frequency:
Horizontal: 30 - 86KHz
Vertical: 47 - 120 Hz (Sax' values range from 50 to 120 !)
Display Area: 320x225mm +/- 5mm (STANDARD MODE) (xorg.conf contains "320x240 !")

Display Modes:
Standard    Resolution     H/V Frequency
IBM/VGA     640x400        31.5kHz/70Hz
IBM/VGA     640x480        31.5kHz/60Hz
VESA/75     640x480        37.5kHz/75Hz
VESA/85     640x480        43.3kHz/85Hz
VESA/75     800x600        46.9kHz/75Hz
VESA/85     800x600        53.7kHz/85Hz
VESA/75     1024x768       60.0kHz/75Hz
VESA/85     1024x768       68.7kHz/85Hz
VESA/75     1280x1024      80.0kHz/75Hz
VESA/65     1600x1200      81.3kHz/65Hz

Comment 1 Marcus Schaefer 2006-02-27 10:01:37 UTC

Thanks for the report. The monitor entry has been fixed in the CDB
Additional sax will not calculate modelines if the nvidia binary driver
is in use

Comment 2 Wolfgang Knauf 2006-02-27 11:02:18 UTC

Thanks for fixing it so quick !

In which version will I find the fix ? 10.1 Beta6 ?

Thanks

Wolfgang

Comment 3 Marcus Schaefer 2006-02-27 11:32:39 UTC

yes in the next beta :-)

Comment 4 Wolfgang Knauf 2006-06-20 14:01:08 UTC

In 10.1 final my monitor runs with 1280x1024@70Hz. Any idea why it is not 75 Hz as the manual tells ?
I have not installed the NVidia driver so far.
