Help me Fix Ubuntu Resolution

[robin.rawal]

Hi. I am a Linux newbie.

I recently installed Ubuntu 7.04 on my system. Intel D945G Motherboard.

I am having some problems with display, .If i select 1024x768, the display is out of screen. Means if i move cursor to the corners, screen scrolls to reveal the remaining part of screen.

LG Studioworks 15" 52V Monitor
Rés Max 1024 x 768 (60Hz)
Dot Pitch 0,28 mm , compatible Plug and Play
Fréq : Horizontal 30 - 54 kHz
Vertical 50 - 120 kHz

If i manually add 1024x768@60hz with this modline.

# 1024x768 @ 60Hz,  47.52 kHz hsync
    Mode "1024x768"
    DotClock     57.40
    HTimings  1024 1040 1104 1208
    VTimings  768 770 772 792
EndMode

Then Vertical display is OK, but he horizontal display is out of screen. Any thing that i can try changing in this modline to make it work ???

XP Pro works fine on 1024x768 @60Hz.

I tried everything, reconfigured xorg, manually entered Horizontal sync, vertical refresh, modlines.


please suggest any fix, or a good, cheap CRT monitor thats works fine with feisty.

i hav another problem with the so called feisty fawn...
it randomy switches to 640X480 and sometimes 1024x768 on its own..
although i hav specified 1024x768....
when it starts with 640X480, i cant see the option 1024x768 in the screen resolution settings...
wat is the problem?

I have LG studioworks, works perfect @ 1024X768. You have to tweak the monitor from the monitor itself.

@Manshahia: open ur /etc/X11/xorg.conf as posted earlier as root(sudo) and remove the lines with 640x480 like one below:

Section "Screen"
    Identifier    "Default Screen"
    Device        "nVidia Corporation G70 [GeForce 7300 GT]"
    Option "AddARGBGLXVisuals" "True"
    Option "DisableGLXRootClipping" "true"
    Monitor        "S/T 57/56E/V"
[U] DefaultDepth   24[/U]

SubSection "Display"
        Depth        24
        [U]Modes        "1024x768"[/U]
    EndSubSection

note ur default depth @ 24-bit.then remove other resolution except the needed resolution from the line Modes;for eg:I've got a samtron 56v with max resolution @ 800x600@85Hz or 1024x768@60Hz-i prefer 800x600 so removed other lines.just do it as underlined one and save;exit.restart X server/gdm now go to Ubuntu menu System >Preferences>SCreen Resolution to fix at maximum frequency.next time u wont see that behaviour of resolution changing.
@robin.rawal:
get ur /etc/X11/xorg.conf section "Screen" to look as below:

#DefaultDepth    24
    SubSection "Display"
        Depth        24
        Modes        "1024x768"
    EndSubSection

go to Ubuntu menu System >Preferences>SCreen Resolution to fix at maximum frequency.
