Thanks!I have tried.But still all the same.Here is a part of my xorg.conf: HorizSync 30 - 60 VertRefresh 75 - 75 #add by myself Section "Modes" Identifier "Modes[0]" # 1024x768 @ 75.00 Hz (GTF) hsync: 60.15 kHz; pclk: 81.80 MHz Modeline "1024x768_75.00" 81.80 1024 1080 1192 1360 768 769 772 802 -HSync +Vsync EndSection Section "Screen" Identifier "Screen 1" Device "** Intel i810 (generic) [i810]" Monitor "My Monitor" DefaultDepth 24 Subsection "Display" Depth 8 Modes "1024x768_75.00" ViewPort 0 0 EndSubsection Subsection "Display" Depth 16 Modes "1024x768_75.00" ViewPort 0 0 EndSubsection Subsection "Display" Depth 24 Modes "1024x768_75.00" ViewPort 0 0 EndSubsection EndSection And I used gtf: #gtf 1024 768 75 # 1024x768 @ 75.00 Hz (GTF) hsync: 60.15 kHz; pclk: 81.80 MHz Modeline "1024x768_75.00" 81.80 1024 1080 1192 1360 768 769 772 802 -HSync +Vsync > > > Now in my xorg.conf: > > > > HorizSync 31.5 - 57.0 > > VertRefresh 50-90 > > > > Even I change them to 20 - 40(HorizSync) and 30 - 60(VertRefresh),the > > frequency is still 85Hz. > > be careful just randomly changing these values - you can sometimes to > bad things to your monitor. > > To stop this, X probes your monitor (if it supports EDID) to get the > refresh and sync values it can display, and it won't let you set the > value outside this. > > I would troll through /var/log/Xorg.0.log and see if you can see > anything interesting about EDID or sync, etc. And I also found information in Xorg.0.log: II) I810(0): Supported VESA Video Modes: (II) I810(0): 720x400@70Hz (II) I810(0): 720x400@88Hz (II) I810(0): 640x480@60Hz (II) I810(0): 640x480@67Hz (II) I810(0): 640x480@72Hz (II) I810(0): 640x480@75Hz (II) I810(0): 800x600@56Hz (II) I810(0): 800x600@60Hz (II) I810(0): 800x600@72Hz (II) I810(0): 800x600@75Hz (II) I810(0): 832x624@75Hz (II) I810(0): 1024x768@87Hz (interlaced) (II) I810(0): 1024x768@60Hz (II) I810(0): 1024x768@70Hz (II) I810(0): 1024x768@75Hz (II) I810(0): Manufacturer's mask: 0 (II) I810(0): Supported Future Video Modes: (II) I810(0): #0: hsize: 800 vsize 600 refresh: 85 vid: 22853 (II) I810(0): #1: hsize: 640 vsize 480 refresh: 85 vid: 22833 (II) I810(0): #2: hsize: 1024 vsize 768 refresh: 85 vid: 22881 (II) I810(0): #3: hsize: 1280 vsize 1024 refresh: 60 vid: 32897 (II) I810(0): Ranges: V min: 50 V max: 130 Hz, H min: 30 H max: 72 kHz, PixClock max 110 MHz (II) I810(0): Monitor name: 1772ED (II) I810(0): Serial No: 1249407921234 (II) I810(0): Will use BIOS call 0x5f05 to set refresh rates for CRTs.
