Bug#294556: xfree86-xserver: savage driver does not query monitor DDC
Package: xfree86-xserver
Version: xserver-xfree86
Severity: normal
Hi, as per the Subject, the savage driver doesn't ask the monitor about
its capabilities via DDC, leading to the X server defaulting to 75 dpi,
and showing very small fonts.
I have observed this behaviour on multiple on-board GFX machines, and
even switching to the 'vesa' generic driver shows the expected results in
the XFree86.0.log, and set the display DPI to 86x84 for a 15" TFT
display.
I can confirm that similar machines using the 'via' driver, and another
machine using 'nv' driver get the DDC info correctly - this problem seems
to be local to the 'savage' driver.
