    Default Graphics Gurus please?

    I have a Samsung 226BW Monitor, it's native recommended resolution is 1680 x 1050, but my eyes are not what they were, and I have problems when running windows inside a VBOX at this resolution. VBOX effectively will not allow a lesser resolution than the host to run in the guest, so I can't see text etc in some programs.
    I decided after weeks of adjusting fonts dpi's etc in both host and guest, that the simple way would be to reduce my resolution.
    Now the monitor is 16:10 aspect ratio, so I found a list of 16:10 resolutions, and tried in YAST (saX2), to select a lower resolution, also at 16:10 ratio using the drop menu in YAST
    I first selected 1440 x 900, clicked "test" and the res. changed BUT it changed to 1152 x 864 (= 13.3333:10 or 1.3333:1 ratio.) I tried again, but no mistake, openSuse REFUSES the 1440 x 900.
    OK I will try 1600 x 1000, obviously this is 16:10.....
    But saX2 also refused to reset to this res., autoselecting instead 1280 x 960 (!!!) which is very different, and is also 1.333:1.
    I have nVidia drivers, which have given no problems so far...

    Can anyone explain in layman's terms what is happening, and whether I can run these screen resolutions?

    I would post my xorg.conf, but I do not know which of the following is "active"

    Code:
    file:///etc/X11/xorg.conf
    file:///var/lib/sax/xorg.conf
    file:///usr/share/man/man5/xorg.conf.5.gz

    file:///var/lib/sax/xorg.conf.md5
    file:///etc/X11/xorg.conf.nvidia-post
    file:///etc/X11/xorg.conf.saxsave
    Here is the first of that list:

    Do you have the VBOX Guest additions installed ? I guess not. If you update VBOX the best thing is to uninstall the guest additions in Windows and then reinstall them via VBOX.
    ° Appreciate my reply? Click the star and let me know why.

    ° Perfection is not gonna happen. No way.

    As it happens Knurpht I updated vBox about a week ago and the Guest additions upgraded smoothly as well, I asked around and it seems vbox can't full screen at a lesser res than the host, if I adjust the XP screen res. (guest) the window appears in a tiny hole surrounded by black, If I fullscreen it it auto-adjusts back to the the largest possible res, ie just smaller than that of the host (openSuse).

    A kindly irc person... (ty aerRosol) has pointed out that I must (or CAN) use
    Code:
    nvidia-settings
    I have looked in there, and my desired resolutions are NOT in the drop menu. I am guessing that
    Code:
    file:///etc/X11/xorg.conf.nvidia-post
    , loads AFTER and over-rides

    I notice that my desired resolutions are not there....

    Do I enter them manually?

    I also notice that that my monitor is called CRT-0 in nvidia-settings....
    Does this mean is has been detected as a CRT, it is of course a flat-panel LCD

    Yes, you can enter them manually but you better make sure that whatever you enter is supported by the hardware. With LCD panels, anything other than the native resolution might look quite gruesome and put your eyes under much more strain than the native, although higher, res.

    Hmmmm (strokes beard)
    16:10 resolutions are NOT there, BUT 1680/1050=exactly 1.6
    Whereas 1400/1050, on the list = 1.333:1 !!
    I AM CONFUSED!
    Where does xandr get its "ideas" from?
    directly from the EDID of the monitor?
    Or from the video driver?
    or from xorg.conf?
    I notice that in my
    Code:
    file:///etc/X11/xorg.conf.nvidia-post
    , "Preferred Mode" is set at 1280x1024... 1280/1024 = 1.25:1....
    Could it be that the monitor has been wrongly identified by nvidea, overwriting the CORRECT id by xorg.conf (??)(??)

    Wink Re: Graphics Gurus please?

    I also notice that that my monitor is called CRT-0 in nvidia-settings....
    Does this mean is has been detected as a CRT, it is of course a flat-panel LCD
    I found this in nVidia's descriptions of their driver here.......


    Appendix*D.*X Config Options


    Code:
    Option "ConnectedMonitor" "string"
    Allows you to override what the NVIDIA kernel module detects is connected to your video card. This may be useful, for example, if you use a KVM (keyboard, video, mouse) switch and you are switched away when X is started. In such a situation, the NVIDIA kernel module cannot detect what display devices are connected, and the NVIDIA X driver assumes you have a single CRT.

    Valid values for this option are "CRT" (cathode ray tube), "DFP" (digital flat panel), or "TV" (television); if using TwinView, this option may be a comma-separated list of display devices; e.g.: "CRT, CRT" or "CRT, DFP".

    NOTE: anything attached to a 15 pin VGA connector is regarded by the driver as a CRT. "DFP" should only be used to refer to digital flat panels connected via a DVI port.


    Default: string is NULL (the NVIDIA driver will detect the connected display devices).
    I guess this explains why nVidia-settings reports CRT-0 ?
    Pretty daft IMHO, my gpu ONLY has a 15 pin VGA OUT! and IS nVidia.If I get a vga/dvi converter, would this overule do you thinks?

    Default Re: Graphics Gurus please?

    In other posts you've written about the resolution of your monitor. You were advised to use LCD@1920x1080. Here I see that the monitor is configured to be a Samsung with preferred mode 1280x1024. There's definitely something going wrong and I think you're trying to solve different things at the same time. Therefor I'm out.

    Knurpht, I have never owned, borrowed, used or even considered using a monitor even capable of 1920x1080. As my eyes are bad I cannot even imagine a scenario where I would need or even want such a resolution (well maybe if I wanted to put my computer output to a wall mounted 2 metre wide television)
    You must have mistaken me for someone else, or there has been a major typo somewhere!
