[Sussex] Resolutions

[Steve Williams]

    Ronan,
    
    I had the same problem when I ran my Iiyama Pro Lite 1600x1200 monitor on DVI output from my graphics card. It seems that standard frame buffer resolutions max at 1024x768.

</edit> on DVI output.

 I believe that Ubuntu uses the standard frame buffer to generate it's window manager displays for compatibility across a wide range of hardware. However, this appears to have been solved in kernel > 2.6.12.
    
    If you can't run a custom kernel, try your monitor on the VGA connector of your graphics card (if it has one of course). You should then be able to set your fb resolution at boot using vga=0x348 (or whatever required).
    
    You may recall I had a prang on a motorcross bike in June and injured my left shoulder. Well it turned out to be a Locked Posterior Dislocation, a really nasty injury that has had to be surgically reduced. So I'm feeling very sore post-op. I hope to be well enough to see everyone at the next SLUG Moot.

        Hi folks
        
        Can anyone shed some light on an annoying X resolution problem?  I'm
        using a flat screen monitor at work (HP 1702 TFT) which is capable of
        1280x1024.  The machine used to have Mandrake 10 on it which happily
        drove the monitor at the right resolution.  However since installing
        Ubuntu, I can't get the resolution higher than 1024x768 without it
        using a virtual desktop space (ie: the desktop extends out beyond the
        monitor ), as if the highest resolution was 1024x768.  I've tried
        generating some Modelines for the full resolution, using the monitor
        specs from the HP site with no joy - same thing happens.  I know it
        will do the full resolution because it has quite happily in the past.
        
        Unfortunately I don't know the Mandrake 10 X server version which might
        have helped, but the current one is the standard Ubuntu Hoary xorg
        version 6.8.2. The graphics card is an on-board Intel 82865G PCI device
        using the native X driver's built resolutions / modes which does list
        1280x1024 as supported in Xorg.0.log.  However the log also contains
        the line
        
        (II) I810(0): Not using built-in mode "1280x1024" (width too large for
        virtual size)
        
        Any ideas anyone?  If you need to know anything else let me know. I can
        attach over xorg.conf files, etc as required.
        
        Cheers
        
        Ronan
