Refresh rate on Dynebolic

Charles G · 10-14-2007, 08:39 PM

Hi,

The mailing list at dyne is down so I thought I'd try here.

I just downloaded dynebolic and got the screen size I want by using "linux vga=792" at boot, which stands for 1024x768 32bit color. That's great, but the low refresh rate really messes with my eyes. In xp I have the refresh set to 85hz.

What I want is 1024x768 @ 85 hz. That's the only mode I need. I went over to http://bohne-lang.de/spec/linux/modeline/ to get the info I need to go into /etc/X11/xorg.conf. the problem is that I don't know what to do with that file. It looks simple, but I've tried various replacements of the information below to no affect. I know I'm just not putting in the file in the correct layout.

Would anyone be willing to put this together for me? I'd really appreciate it.

Charles

Code:

  Horizontal Resolution:   1024 
  Vertical Resolution:      768 
  Vertical Refresh Rate:   85.00 Hz 
  Horizontal Refresh Rate: 68.79 KHz 
  Dot Clock Frequence:     97.41 MHz 

 # V-freq: 85.00 Hz  // h-freq: 68.79 KHz
 Modeline "1024x768" 97.41  1024 1072 1192 1416   768  768  771  809

The monitor/video stuff in the xorg.conf file. It seems to be much more than I would need:

Just so I understand what you are wanting, is the config stuff in the top code box what you want entered into xorg.conf? And is the the bottom code box the current config listed in you xorg.conf file?

Charles G · 10-15-2007, 03:03 PM

Exactly. Thank you.

It's not exactly possible to get an 85 Hz refresh rate when your VertRefresh has a max of 72. You need to find out what HorizSync and VertRefresh rates your monitor actually supports, and enter those values. Calculating a modeline yourself is largely unnecessary these days.

So, what monitor are you using?

Charles G · 10-15-2007, 09:33 PM

My monitor is REAL Flat 996F (listed as 996F-BK, -BK for black) by REALsync.

Wim Sturkenboom · 10-15-2007, 11:15 PM

As indicated by ciotog, your problem lays in the lines

Code:

	HorizSync       28-48
	VertRefresh     43-72

Find the specs for yuur monitor, change the above values save the file, forget about the first codeblock that you posted and restart X.

That should do the trick.

You might still find an issue that you can not get over 75Hz. In that case, add Option "UseEdidFreqs" "False" to the device section of xorg.conf.

ciotog · 10-16-2007, 06:52 AM

According to this page:
http://pcclub.com/support_articles_d...A331F1FE333C17

you want

Code:

	HorizSync       30-95
	VertRefresh     50-180

If for some reason those numbers aren't valid, assuming the monitor is reasonably made then it should say "out of range" without causing any damage.

Charles G · 10-16-2007, 12:40 PM

Yes, that does the trick. Thanks everyone!

I did another quick check online, and found the following:
http://www.pcreview.co.uk/forums/thread-292236.php

This is a driver information file for Windows, and includes the following section:

[996F.AddReg]
HKR,"MODES\1600,1200",Mode1,,"30.0-95.0,50.0-150.0,+,+"
HKR,,MaxResolution,,"1600,1200"
HKR,,DPMS,,1

This suggests that the VertRefresh range should be 50-150, not 50-180.
