Public bug reported:
Binary package hint: xserver-xorg
my pc: amd xp 1700+
ram 731M
graphic card nvidia geforce fx 5200
i'm using the proprietary driver nvidia provided with the above releases
after a recent update (i cannot state when, but it should be during the last
week) i did not get any longer the usual 1280 x 1024 resolution but 640 x 480
only in both edgy and feisty.
examining the Xorg.93.log (btw why it is not .0. anymore?) it appears that all
but 640 x 480 are not validated, please find underneath the interisting snippet:

(II) NVIDIA(0): Validated modes:
(II) NVIDIA(0): "640x480"
(II) NVIDIA(0): Virtual screen size determined to be 640 x 480
the xserver version in both edgy and feisty is 7.1.1ubuntu6
after searching google for a solution and having added a lot of option relevant
to avoiding EDID from probing freq's
i have decided to use the xorg.conf of debian sid which i run in the same pc as
edgy and feisty and .... it worked fine, the main difference being the presence
in the sid file, in the section monitor. of the monitor minimum e maximum
frequencies.
** Affects: xorg (Ubuntu)
