wrong dpi after update

[Bernd Schubert]

Hi,

I'm using Debian Sid on my desktop system, but I did the last update some
weeks ago. After updating today several parts of X got updated and now
something goes wrong with display-size detection and hence the display dpi
is wrong (as are all font sizes).

(II) RADEON(0): Supported additional Video Mode:
(II) RADEON(0): clock: 162.0 MHz   Image Size:  367 x 275 mm

bernd at bathl ~>xrandr
Screen 0: minimum 320 x 200, current 1600 x 1200, maximum 1600 x 1200
VGA-0 disconnected (normal left inverted right x axis y axis)
DVI-0 connected 1600x1200+0+0 (normal left inverted right x axis y axis)
367mm x 275mm
   1600x1200      60.0*+   59.9

But:

(II) RADEON(0): EDID Version: 1.3
(II) RADEON(0): Digital Display Input
(II) RADEON(0): Max H-Image Size [cm]: horiz.: 41  vert.: 31
(II) RADEON(0): Gamma: 2.20

410x310 mm is the correct display size, but somehow by default 367x275 mm
are used. And even though EDID provides correct information?
Setting the correct value with "xrandr --fbdev 410x310" does work, but in
the past this did work automatically?


Thanks,
Bernd
