Complete Newbie.... 640x480 resolution only

[UKCamaroSS]

Hi,

I have just installed Ubuntu 7.10 on my pc as a dual boot with XP. I have set up / activated the Restricted drivers. I have an Nvidia FX5700LE graphics card, and my computer is connected to a 26" Sharp LCD TV via a DVI cable.

I am only able to see the Ubuntu screen in a 640x480 resolution...... I have no other option available..... can anyone help me?
I would ideally like my native resolution (1366*768), but EDID may be a problem... really anything other than 640 would be a great start!!

Cheers,

please read the sticky posts.

Then read the README provided by the driver. If you still have questions (or the ways to reach your goal do not work), come back and post at least your xorg.conf and Xorg.0.log. And better, the complete log of nvidia-bug-report.sh

Hi,

Thanks for the hints... I have searched on this site and other sites, but can not find the information I need.
I'm a complete newbie (a few days with Linux) and am struggling like mad. I have no idea where the readme is for the driver that Ubuntu Restricted drivers installed, so I haven't read that.

The only resolution I can get is 640*480.

As a newbie, I'm sorry, but I dont know how to run Xorg.0.log or the xorg.conf.
I have found instructions on how to get the nvidia-bug-report.sh - so it is attached:

xorg.conf is the config file for X and it is in /etc/X11. Xorg.0.log is the default log file of X and it is in /var/log. The readme should be in /usr/share/doc/nvidia-drivers or whereever ubuntu has put it. But you can read it on the nvidia page:
http://us.download.nvidia.com/XFree8...DME/index.html

ok, lets see:
(II) NVIDIA(0): enabled.
(WW) NVIDIA(GPU-0): The EDID read for display device DFP-0 is invalid: EDID
(WW) NVIDIA(GPU-0): version 1 size exceeds EDID buffer size, or checksum for
(WW) NVIDIA(GPU-0): EDID failed.
(--) NVIDIA(GPU-0):

yes, you were right, edid problems.

II) NVIDIA(0): Assigned Display Device: DFP-0
(WW) NVIDIA(0): No valid modes for "1280x768"; removing.
(WW) NVIDIA(0):
(WW) NVIDIA(0): Unable to validate any modes; falling back to the default mode
(WW) NVIDIA(0): "nvidia-auto-select".
(WW) NVIDIA(0):
(II) NVIDIA(0): Validated modes:
(II) NVIDIA(0): "nvidia-auto-select"
(II) NVIDIA(0): Virtual screen size determined to be 640 x 480
(WW) NVIDIA(0): Unable to get display device DFP-0's EDID; cannot compute DPI
(WW) NVIDIA(0): from DFP-0's EDID.
(==) NVIDIA(0): DPI set to (75, 75); computed from built-in default

is the result.

ok, you should play around with this option (from the readme):
Option "UseEDID" "boolean"
By default, the NVIDIA X driver makes use of a display device's EDID, when available, during construction of its mode pool. The EDID is used as a source for possible modes, for valid frequency ranges, and for collecting data on the physical dimensions of the display device for computing the DPI (see Appendix E, Dots Per Inch). However, if you wish to disable the driver's use of the EDID, you can set this option to False:
Option "UseEDID" "FALSE"

Note that, rather than globally disable all uses of the EDID, you can individually disable each particular use of the EDID; e.g.,
Option "UseEDIDFreqs" "FALSE"
Option "UseEDIDDpi" "FALSE"
Option "ModeValidation" "NoEdidModes"

Default: True (use EDID).

Section "Device"
Identifier "nVidia Corporation NV36 [GeForce FX 5700LE]"
Driver "nvidia"
BusID "PCI:1:0:0"
Option "UseEDID" "FALSE"

and play around with those options:
Option "DPI" "string"
This option specifies the Dots Per Inch for the X screen; for example:
Option "DPI" "75 x 85"

will set the horizontal DPI to 75 and the vertical DPI to 85. By default, the X driver will compute the DPI of the X screen from the EDID of any connected display devices. See Appendix E, Dots Per Inch for details. Default: string is NULL (disabled).
Option "UseEdidDpi" "string"
By default, the NVIDIA X driver computes the DPI of an X screen based on the physical size of the display device, as reported in the EDID, and the size in pixels of the first mode to be used on the display device. If multiple display devices are used by the X screen, then the NVIDIA X screen will choose which display device to use. This option can be used to specify which display device to use. The string argument can be a display device name, such as:
Option "UseEdidDpi" "DFP-0"

or the argument can be "FALSE" to disable use of EDID-based DPI calculations:
Option "UseEdidDpi" "FALSE"

See Appendix E, Dots Per Inch for details. Default: string is NULL (the driver computes the DPI from the EDID of a display device and selects the display device).

after your changes (as root, or sudo), restart X and have a look at the log-file.
