Public bug reported:
Binary package hint: xserver-xorg-video-ati
For some odd reason using the radeon driver reports in Xorg.0.log that:
(--) RADEON(0): Mapped VideoRAM: 262144 kByte (128 bit DDR SDRAM)
(II) RADEON(0): Color tiling disabled
(II) RADEON(0): Max desktop size set to 2560x1600
(II) RADEON(0): For a larger or smaller max desktop size, add a Virtual line to
your xorg.conf
(II) RADEON(0): If you are having trouble with 3D, reduce the desktop size by
adjusting the Virtual line to your xorg.conf
One would figure out that ok, now it has obeyed my request for larger
virtual desktop (in order to support two screens of size 1280x1024 -- I
have Virtual 2560 2560 in the Screen -section of xorg.conf.)
Having later logged in and try with xrandr:
$ xrandr --output DVI-1 --right-of DVI-0
xrandr: screen cannot be larger than 1280x1280 (desired size 2560x1024)
$ xrandr
Screen 0: minimum 320 x 200, current 1280 x 1024, maximum 1280 x 1280
DVI-1 connected 1280x1024+0+0 (normal left inverted right x axis y axis) 376mm
x 301mm
1280x1024 60.0*+ 75.0 60.0*
// -- rest of the modelines snipped
DVI-0 connected 1280x1024+0+0 (normal left inverted right x axis y axis) 376mm
x 301mm
1280x1024 60.0*+ 75.0 60.0*
// -- rest of the modelines snipped
I've also tried Virtual 2560 1024 (the desired one), the same with
radeonhd. fglrx hangs up cold when attempting to use two screens with
it.
It'd seem that a later version than the current is available of the
radeon driver. Any chance of getting it into Jaunty? Changelog had some
items concerning 4600 series.
