Refresh rate limited to 60 hz in Ubuntu? (FIXED)

[AljoshaNL]

Hi,

Just installed ubuntu, and it's great Only one problem: Refresh rate is locked at 60 hz, it's erally annoys me. The only way of having a normal expreciende is to use 800x680 resolution, which is just too small for me :-X
I used Xconfigurator in CollegeLinux (slackware), is there anything like that for Ubuntu(newest version, .10 I guess)

Graphical card is GeForce 2 MMX 400
Monitor is a Sony GDM-17E21

hi AljoshaNL,
The refresh rate is typically set to the highhest availbe setting for xorg -but if this fails (as it sometimes does) then we can plade with the modelines and get it working properly. To do think you need to know teh specs - I think these can be retrieved with some tools (can't remember name now...) - but this moniter does not show up for me under sony - but silicon graphics, the manual would also help with mode lines.

I found these specs for that monitor, but as PBHarris said, it appears a Silicon Graphics, not Sony.

 Silicon Graphics GDM-17E21 (Sony Trinitron OEM)
Resolution: H Max = 1280 dots, V Max = 1024 lines
Deflection freq: H = 30-85 Hz, V = 48 to 150 Hz

SGI Part No.:           061-0010-001
Resolution:             1280x1024
Vertical Scan:          48-160 Hz
Horizontal Scan:        30-85kHz

Of course, now I notice it says Sony Trinitron OEM....

You might want to open your /etc/X11/xorg.conf file and make sure those are the values entered for your monitor.

Yup, it's a silicon graph. monitor, but sony manifactured it.
Thanks for all the replies, going to try it out.
BTW how did you find the specs? I searched for them until madness!

[trickster]

I usually Google for the monitor name. Specs for it usually come up pretty fast.

[AljoshaNL]

That's exactly what I did :-[...
/but back to the point:
I changed xorg.conf file:

Section "Monitor"
Identifier"Generic Monitor"
Option"DPMS"
HorizSync30-85
VertRefresh48-160
EndSection

The thing I changed was the Sync rates to the Sync rates my specs showed.
I didn't find something about 'refresh rates' in the file, so I made my changes and restarted the X-server... (logout and login again, taht's what I did)
I didn't find more refresh rates in the 'resolution' config applet.

[trickster]

Those are the changes needed. After that, it is supposed to automagically adjust the refresh rate to the best value possible for the resolution you are using.

[AljoshaNL]

Thanks for all replies, amazing how fast I got help ;D
I didn't experience this with M$

I had to reboot my system, not just logout-login (yes that worked with Fedora)...

Thanks!!! Aljosha
