 Posted: Sun Nov 23, 2003 12:11 pm Post subject: Supported resolution not available in gentoo |
 |
|
| My monitor is capable of 1024x768 resolution, and I'm able to use it in Windows, but gentoo seems to be incapable of this resolution. XF86config is set to have this as the default resolution, but my only options inside both gnome and kde are 800x600 and 640x480. Is there anything I can do to force this resolution? |

you can try editing your /etc/X11/XF86Config file
here you can add a resolution for your screen under Modes:
| Code: |
Section "Screen"
Identifier "Screen 1"
Device "geforece4nv"
Monitor "kds"
DefaultDepth 24
Subsection "Display"
Depth 8
Modes "1280x1024" "1024x768" "800x600" "640x480"
ViewPort 0 0
EndSubsection
Subsection "Display"
Depth 16
Modes "1280x1024" "1024x768" "800x600" "640x480"
ViewPort 0 0
EndSubsection
Subsection "Display"
Depth 24
Modes "1280x1024" "1024x768" "800x600" "640x480"
ViewPort 0 0
EndSubsection
EndSection
|
just be careful, you might have to specify the amount of ram you have (videoram):
| Code: |
# Device configured by xf86config:
Section "Device"
Identifier "geforece4nv"
# Driver "nv"
Driver "nvidia"
Option "NvAGP" "3"
#VideoRam 65536 #Specify the amount of ram in kilobytes
# Insert Clocks lines here if appropriate
EndSection
|
also your monitor settings that you specified might not allow for higher resolutions
you can switch between different available resolutions by ctrl-alt-"+" and if you need to kill the xserver ctrl-alt-backspace
hope this helps |

| Thanks, but as I said, I already taylored XF86config for my system, including the resolutions my monitor is capable of. I even tried deleting all but 1024x768 and all that got me was a command prompt on reboot, and I had to go in and put the 800x600 back on to get a graphical interface. The problem is that Xfree86 is skipping over 1024x768 because it thinks my monitor doesn't support it. I need a way to /force/ it go to this resolution. |

What is the refresh rate for 1024x768 in Windows? Without a special modeline, XFree86 will only use the
nice VESA standard ones (e.g., 72, 75, 85Hz). |
