Description Joerg Battermann 2005-09-19 18:51:52 UTC

Hello there,

I just installed the OpenSuSE RC1 on my machine, but sax didn't detect my 24"
TFT screen (a Dell 2405 widescren one, native res: 1920x1200) and said it would
be a vesa 1024@60hz one. Trying to use the LCD -> 1920x1200@75hz always results
into a black screen, and not ctrl+alt+backspace nor ctrl+c revives the system...
so a reboot/reset is necessary. Since it's adviced to NOT edit the xorg.conf
file I am wondering what to do...

Ubuntu & Fedora both work fine with the monitor (autodetect it's capabilities),
and lower resolutions e.g. 1600x1200 work too.


I am using the nvidia driver btw.

Best Regards,
-Joerg Battermann

Comment 4 Joerg Battermann 2005-09-19 19:50:33 UTC

According to google, the correct modeline for the monitor would be:

Modeline "1920x1200" 154.00 1920 1976 2008 2080 1200 1203 1209 1235 +hsync +vsync

what should I do now? edit the xorg manualy?

Comment 5 Stefan Dirsch 2005-09-19 21:21:32 UTC

Sure, you can edit it. :-)

Comment 6 Joerg Battermann 2005-09-20 06:41:05 UTC

I was just asking because I don't want to re-edit the file after each update etc...

Is it possible to add the monitor to the sax2-database so the user can properly
select it and/or sax autodetects it?

Comment 7 Stefan Dirsch 2005-09-20 08:26:07 UTC

Sure, it would be possible to add the monitor to the sax2-database, but it 
won't help since no special modelines for monitors are stored. Does this 
modeline help at all?

Comment 8 Joerg Battermann 2005-09-20 13:35:31 UTC

replacing the 1920 modeline generated by sax with the one mentioned in #4 works
perfect. :)

what would be necessary to add the monitor to the sax2-db so other users with
that monitor have no such problem(s)?

Don't know (if this will be possible). But Marcus should know.

could you send me the output of the command 
 
   hwinfo --monitor 
 
Thanks

hwinfo --monitor output

here's the requested information. However, it does not seem correct (?). I ran
it with init-level 3....

Comment 12 Marcus Schaefer 2005-09-21 08:45:15 UTC

Thanks I added the following monitor to the CDB 
 
+#============================================== 
+# 2405 FPW
