Screen Resolution - PC-BSD Forums

Aeon · #1 11-01-2005, 08:36 PM

Hi!

On Ms Windows I get a 1280x1024px as maximum screen resolution. On PCBSD I get as maximum screen resolution 1024x768px.
Is there a way to configure PCBSD, so I could get a 1280x1024px as screen resolution?

My monitor is a ViewSonic A70f-2 which has a fH 30-70khz and fV 50-160Hz

My video card is a 3Dfx Interactive, Inc. Voodoo3

On Linux I use TDFX as controler.

thanks.

Open konsole and enter
su

then type

cp /etc/X11/XF86Config /etc/X11/XF86Config-backup

This makes a backup of the file /etc/X11/XF86Config incase something goes wrong. Then type

edit /etc/X11/XF86Config

You will need to change the section that says:

Code:

   SubSection "Display"
           Modes    "1024x768" "800x600" "640x480"

to say:

Code:

   SubSection "Display"
           Modes    "1280x1024" "1024x768" "800x600" "640x480"

STEP TWO
Providing you gave the correct refresh rate times in your post ...... ONLY change the HorizSync and VertRefresh lines - don't touch anything else.

Code:

Section "Monitor"
   Identifier   "Monitor0"
   HorizSync    30.0 - 70.0
   VertRefresh  50.0 - 160.0
EndSection

I "THINK" your card uses the following driver

Code:

Section "Device"
   Identifier  "Card0"
   Driver      "tdfx"
EndSection

The restart. If KDE fails to start up, then log in as user root and type

mv -f /etc/X11/XF86Config-Backup /etc/X11/XF86Config

This will force your working backup copy of /etc/X11/XF86Config back into place. To restart type

killall kdm

or restart with ctrl+alt+delete or the

shutdown -r now

command. GOOD LUCK!

It works. Thanks.

This is the problem of PC-BSD not knowing what is the best configuration for the detected hardware... A thourough hardware embedded database with information on configurations would solve these kinds of issues once for all :roll:

yes, one or two person are about to write the tool and the others collect datas of the monitors.

this problem which affects many oss is linked to the difficulty in finding the correct Y-sync and V-sync values.

I have adressed this problem and discussed it with youlle some time ago.

We have found a way to find the correct values using ddc (search for ddc probe on google).

Andrew told me he has takled to Kris and work is under way already to create a pc-bsd ddc probe mechanism.

Other Linux OS's already use this method (Knoppix) combined with a database so that should be the way to go.

Yes, way too difficult for the targetted audience.

I think that SuSE and RedHat already have DDC database- why not use their knowledge?
