 Posted: Mon Aug 11, 2003 7:03 am Post subject: Don't want EDID |
 |
|
I have a GeForce 2 Ti card, and my X setup gets the monitor settings through the nvidia driver's EDID detection feature. However, that means that my screen has to be turned on when I start the X server, something that has come to be an annoyance.
EDID settings remind me of DHCP (get your IP address automatically). But how do I store them in my configuration? (The analogy of using ifconfig with settings retrieved from /etc/dhcpc)
I've tried read-edid, with no success.
| Code: | # get-edid > EDID

These settings are obviously incorrect, as I'm doing 1024x768, and my monitor can't seem to go any higher than 60hz.

If you don't want it, I think there is a setting for the nVidia drivers called "IgnoreEDID". Just turn it on in your XF86Config and it shouldn't use EDID.

Well, I've tried that, but apparently I set my frequencies wrong - X said it couldn't find usable configurations. So I need to know how to pull the data from EDID and put it in XF86Config first.

tactless, what Erik is saying is just cut & paste everything from the output of parse-edid into your XF86Config file. Actually, all you need is the stuff between (and including): | Code: |
Section "Monitor"
...
EndSection
|
If the frequencies are incorrect, then you'll have to manually edit them (but I would be really surprised if the EDID was wrong). Maybe your understanding of the settings is wrong, so maybe re-check the XF86Config documentation. (I personally don't understand the DotClock, HTimings, and VTimings stuff so can't help you there.)
Once you've pasted in the Section "Monitor" stuff, then search for Section "Screen" and make sure the Monitor option points to the identifier in the Monitor section. In your case it would be something like: | Code: |
Section "Screen"
Identifier "Screen 1"
Device "NVIDIA..."
Monitor "___:56d5" <--- because this is the Identifier from EDID
...
EndSection

But the resolutions are all 640x480! My monitor can do 1024x768!

Ah, the read-edid web page says it only supports 1.0, 1.1, and 1.2 versions of EDID and from your get-edid output it looks like your monitor may even be higher than 1.3 (which he specifically mentions as not being supported).
You might want to send your EDID to him as a sample to help him develop support.
In the meantime, just make your own entry. I got by with an older monitor by just doing this: | Code: |
Section "Monitor"
Identifier "Mymonitor"
HorizSync 79.9
VertRefresh 75
EndSection
|
In other words, force a specific refresh rate (no range).
Then, if you never want to change resolutions, just do 1280x1024 in the Screen Section. e.g.: | Code: |
Section "Screen"
Identifier "Screen 1"
Device "NVIDIA ..."
Monitor "Mymonitor"
DefaultDepth 24
Subsection "Display"
Depth 24
Modes "1280x1024"
ViewPort 0 0
EndSubsection
EndSection
|
Don't forget the IgnoreEDID in the NVidia section of course. |

Okay, I used the values from xvidtune, and that seems to work. However, my Freetype fonts are much smaller now... I'm guessing the DPI was sent out of whack. How do I fix?
