Guest La_Parca Posted July 26, 2007 Report Share Posted July 26, 2007 For some reason I just cant seem to get the refresh rate down from 85hz to 60hz on the intel 830 965 drivers...in 800x600 cant even get it to display in 1024x768 but if i switch to the xorg vesa drivers everything is fine just a bit sluggish so any help would be appreciated and I tried altering the xorg.conf with no success .... maybe doing it all wrong... Help.... Quote Link to comment Share on other sites More sharing options...
pmpatrick Posted July 26, 2007 Report Share Posted July 26, 2007 First thing to do is make sure you have the correct monitor chosen for your system and that you have selected the intel "i810" driver not the 830 one you used before. That should get you to higher resolution. Then post your /etc/X11/xorg.conf file as configured for the i810 driver. If you know the horizontal sync and vertical refresh rate specs for your monitor, post that as well. I have the same intel 965 chipset motherboard with intel integrated graphics and had to generate a custom modeline to get my refresh rate down to 60Hz. You may wind up having to do the same but it's not that hard. Also, i810 is he correct driver for this graphics chipset for the several distros I've tried. I believe in fedora 7 they offered the intel 830 as an alternative but it was marked "experimental" and not recommendedm i.e. it's still in development. The older i810 worked much better for me and that's what was auto-configured on every distro I tried. Quote Link to comment Share on other sites More sharing options...
Guest La_Parca Posted July 26, 2007 Report Share Posted July 26, 2007 (edited) problem is i have only a projector and when i try to change the resoution to 1024x768x60 it only gives me signal out of range ... as far as i can tell can only handle 85hz max.... its an infocus x1a and max pc rez is 1024x768x60hz unfortunately the manual says nothing about the horizontal refresh rate... here's my xorg.config # File generated by XFdrake (rev 142098) # ********************************************************************** # Refer to the xorg.conf man page for details about the format of # this file. # ********************************************************************** Section "Files" # font server independent of the X server to render fonts.

Edit: actually found the info at their site ..... vsync 50-85hz and hsync 31.5-80khz by the way... did you mean the xorg i810 or the intel 810 drivers? cuz this is done with the intel 810 Edited July 26, 2007 by La_Parca Quote Link to comment Share on other sites More sharing options...
adamw Posted July 26, 2007 Report Share Posted July 26, 2007 VertRefresh 50-85 change that line to: VertRefresh 60 Quote Link to comment Share on other sites More sharing options...
pmpatrick Posted July 26, 2007 Report Share Posted July 26, 2007 Use i810. I tried adamw's way with mine and it didn't work but try that first as it's a lot easier. If it doesn't work, try generating a mode line and see if that helps. Open a console and run: $ gtf 1024 768 60 You should get some output that looks something like this: # 1024x768 @ 60.00 Hz (GTF) hsync: 47.70 kHz; pclk: 64.11 MHz Modeline "1024x768_60.00" 64.11 1024 1080 1184 1344 768 769 772 795 -HSync +Vsync Cut and paste that output into your "Monitor" section of xorg.conf like so: Section "Monitor" Identifier "monitor1" VendorName "Plug'n Play" ModelName "InFocus X1a-A" HorizSync 31.5-80 VertRefresh 50-85 # 1024x768 @ 60.00 Hz (GTF) hsync: 47.70 kHz; pclk: 64.11 MHz Modeline "1024x768_60.00" 64.11 1024 1080 1184 1344 768 769 772 795 -HSync +Vsync # TV fullscreen mode or DVD fullscreen output. # 768x576 @ 79 Hz, 50 kHz hsync ModeLine "768x576" 50.00 768 832 846 1000 576 590 595 630 # 768x576 @ 100 Hz, 61.6 kHz hsync ModeLine "768x576" 63.07 768 800 960 1024 576 578 590 616 EndSection Next, go into XFdrake and select the higher resolution of 1024x768 for your output. When it asks if you want to restart the X server, say no. Check and make sure XFdrake doesn't edit out your inserted modeline in xorg.conf. I don't think it will but you never know. If it did, just cut and paste the modeline back in. In the "Display" subsection you should see new listings for "1024x768" for the various color depths. Log out and when you see the login screen hit Ctrl-Alt-Backspace just to make sure the X server has been restarted. Log back in and see if the whole thing works OK. Your modeline should force 60Hz refresh rate at 1024x768. The modeline method was the only way I could get my refresh rate down from 75Hz.

daniewicz Posted July 27, 2007 Report Share Posted July 27, 2007 (edited) Hmm. I was not aware of the gtf utility. Thanks pmpatrick Edited July 27, 2007 by daniewicz Quote Link to comment Share on other sites More sharing options...
Guest La_Parca Posted July 28, 2007 Report Share Posted July 28, 2007 thanks alot for the help but i tried what adamw said and no go still at 85hz now I tried to open up a terminal and run that entry but it just says command not found command not found.... could i just copy and paste that modeline you posted earlier and paste it into my xorg.conf and see it it works and no idea where xfdrake is ... sorry for the trouble but this will be my first attempt at linux and having a lot of trouble with the video card is my first ...jejeje.... im using mandriva free spring with gnome as my windows manager.. i will try to use your modeline but dont know where xfdrake is so ill just change the resolution through mcc and see if it works....

Guest La_Parca Posted July 28, 2007 Report Share Posted July 28, 2007 (edited) sorry for the inexperience on my part but i finally got the modeline going for me but still no idea where xfdrake is jejeje.. is it the on in applications system configuration hardware screen resolution? Edit: I dont know how this is going on but when i first installed mandriva it was giving me 60hz for the first couple of restarts then bam 85hz so i will reinstall it and see if it happens again...
