Help. Can't adjust screen resolution or TwinView


Newbie-question I guess...

I'm running RedHat 8.0 (Psyche)

Two problems:

1. How can I adjust the screen resolution using the nvidia-drivers?
2. How do I enable dual(twin)-view to get an extended desktop using a GF4 ti4600 with two monitors hooked up?

Ok, I've tried several things in my XF86Config without any results.
The drivers are installed and works fine I think, the Nvidia-logo flashes when I start Gnome, but I'm stuck with 1024x768! In the display setting screen that's the only resolution I can choose. (Also the "enable 3d acceleration" option is greyed out). I would really like 1280x1024 but no matter what I write in XF86Config, the resolution stays the same.

Hope someone can help a Linux-Idiot.
Regards Joakim



Here's my XF86Config:


# XFree86 4 configuration created by pyxf86config

Section "ServerLayout"
Identifier "Default Layout"
Screen 0 "Screen0" 0 0
InputDevice "Mouse0" "CorePointer"
InputDevice "Keyboard0" "CoreKeyboard"
InputDevice "DevInputMice" "AlwaysCore"
EndSection

Section "Files"
# RgbPath is the location of the RGB database. Note, this is the name of the
# file minus the extension (like ".txt" or ".db"). There is normally
# no need to change the default.
# Multiple FontPath entries are allowed (they are concatenated together)
# By default, Red Hat 6.0 and later now use a font server independent of
# the X server to render fonts.
RgbPath "/usr/X11R6/lib/X11/rgb"

# Option "Xleds" "1 2 3"
# To disable the XKEYBOARD extension, uncomment XkbDisable.
# Option "XkbDisable"
# To customise the XKB settings to suit your keyboard, modify the
# lines below (which are the defaults). For example, for a non-U.S.
# keyboard, you will probably want to use:
# Option "XkbModel" "pc102"
# If you have a US Microsoft Natural keyboard, you can use:
# Option "XkbModel" "microsoft"
#
# Then to change the language, change the Layout setting.
# For example, a german layout can be obtained with:
# Option "XkbLayout" "de"
# or:
# Option "XkbLayout" "de"
# Option "XkbVariant" "nodeadkeys"
#
# If you'd like to switch the positions of your capslock and
# control keys, use:
# Option "XkbOptions" "ctrl:swapcaps"
# Or if you just want both to be control, use:
# Option "XkbOptions" "ctrl:nocaps"

Have you tried [ctrl] + [alt] + [+]? That is how you cycle through available resolutions. The 'display'section of XF86Config looks good: but 1280x1024 should be your default res the way you have it set up.

I would doublecheck your HorizSync, and VertRefresh figures though. Usually they are a range. If you don't know the correct range then search for your monitor model at the manufacture's website and plug in the correct values. If these are the correct figures then I don't think your monitor can support the larger resolution (at least not in 24 bit colour mode).

Be sure to back the present file up before making changes.

The CtrlAlt-/+ only leaves me in a lower resolution...

Thanks, good idea. I'll check up on the specs of the monitor.
I just used the default values, probably not a good idea. In XP I'm using 1280@80Hz so it should be capable.
I'll leave a post if it works.

Yes! Looking at my 1280x1024 desktop.

Thanks for the tip!!! Specifying the HorizSync and VertRefresh did the trick.

Now I only have to get both monitors to work in TwinView mode and I'm all over the moon.

Can't help you there...sorry.

Have a search for "two monitors" or "dual head", you might get lucky...
