Bug Description
Binary package hint: xorg
It seems tools like xdpyinfo are reporting screen sizes as 300x230 mm in a lot of cases when they are not.
On my own Iiyama ProLite E431S with an ATI Radeon 9800 Pro connected over DVI using the "ati" driver, I get this from xdpyinfo:
screen #0:
dimensions: 1280x1024 pixels (300x230 millimeters)
resolution: 108x113 dots per inch
ddcprobe correctly detects the screen physical dimensions:
screensize: 34 27
In another report, https:/
screen #0:
dimensions: 1280x800 pixels (300x230 millimeters)
resolution: 108x88 dots per inch
and ddcprobe reports:
screensize: 33 21
Notice that the screens are actually different dimensions, both in physical terms and pixel terms, yet xdpyinfo thinks they are 300x230 mm. Also, the other reporter is using the intel driver.
This did indeed used to work correctly in the early Hardy alphas, and previous releases of Ubuntu.
