    Default Can Not Increase Resolution on Intel Graphics Card!!!

    I just installed opensuse 12.2 from dvd, I have seen display settings. It shows maximum resolution of 1024*768. But I have used M$ Windows with 1280*1024 resolution. How can I increase it on OpenSUSE? I have Intel Q965/963 graphics. I haven't iinstalled any driver yet.

    You should start by checking /var/log/Xorg.0.log, as it will help with the diagnosis. It is a lengthy file, so if you want to share it here, upload the contents to SUSE Paste

    It could be an EDID issue, or perhaps the graphics driver in use.

    Okay, so it is an EDID issue...
    Code:
    1. [ 23.995] (II) intel(0): Output VGA1 has no monitor section
    2. [ 24.011] (II) intel(0): EDID for output VGA1
    3. [ 24.011] (II) intel(0): Printing probed modes for output VGA1
    4. [ 24.011] (II) intel(0): Modeline "1024x768"x60.0 65.00 1024 1048 1184 1344 768 771 777 806 -hsync -vsync (48.4 kHz e)
    5. [ 24.011] (II) intel(0): Modeline "800x600"x60.3 40.00 800 840 968 1056 600 601 605 628 +hsync +vsync (37.9 kHz e)
    6. [ 24.011] (II) intel(0): Modeline "800x600"x56.2 36.00 800 824 896 1024 600 601 603 625 +hsync +vsync (35.2 kHz e)
    7. [ 24.011] (II) intel(0): Modeline "848x480"x60.0 33.75 848 864 976 1088 480 486 494 517 +hsync +vsync (31.0 kHz e)
    8. [ 24.011] (II) intel(0): Modeline "640x480"x59.9 25.18 640 656 752 800 480 489 492 525 -hsync -vsync (31.5 kHz e)
    9. [ 24.011] (II) intel(0): Output VGA1 connected
    10. [ 24.011] (II) intel(0): Using fuzzy aspect match for initial modes
    11. [ 24.011] (II) intel(0): Output VGA1 using initial mode 1024x768
    So, this can be due to a variety of reasons: the monitor itself misreporting, the VGA cable (not passing pin #12 IIRC), or a KVM switch perhaps.

    Anyway, one way around this is to manaully configure using small adjustments in /etc/X11/xorg.conf.d/50-monitor.conf and 50-screen.conf, although you need to be confident with editing system files, and I recommend backing the original files up in case you need to resotre them later. If the X-server fails to start as the result of a change you made, you may need to edit at runlevel 3 (console only).

    You may need to generate a suiatable modeline, based on the specs of your monitor. For example, suppose it is capable of 1680x1050@60Hz, then...
    Code:
    cvt 1680 1050 60
    # 1680x1050 59.95 Hz (CVT 1.76MA) hsync: 65.29 kHz; pclk: 146.25 MHz
    Modeline "1680x1050_60.00"  146.25  1680 1784 1960 2240  1050 1053 1059 1089 -hsync +vsync
    Add the desired modeline(s) to 50-monitor.conf...

    Code:
    #Section "Monitor"
    #  Identifier "Default Monitor"
    #
    #  ## If your monitor doesn't support DDC you may override the
    #  ## defaults here
    #  #HorizSync 28-85
    #  #VertRefresh 50-100
    #
    #  ## Add your mode lines here, use e.g the cvt tool
    Modeline "1680x1050_60.00"  146.25  1680 1784 1960 2240  1050 1053 1059 1089 -hsync +vsync
    #
    #EndSection

    50-screen.conf...

    Code:
    #Section "Screen"
    #  Identifier "Default Screen"
    #
    #  Device "Default Device"
    #
    #  ## Doesn't help for radeon/radeonhd drivers; use magic in
    #  ## 50-device.conf instead
    Monitor "Default Monitor"
               Subsection "Display"
                   Modes    "1680x1050_60.00"
               EndSubSection
    EndSection
    The 'Modes' entries must match your modeline names. Be careful with your editing - the X-server will discard entries with errors. Once complete, restart the X-server with CTRL-ALT-Backapsace (twice).

    Thanks, it worked.
