** Attachment added: "xorg.conf"
http://launchpadlibrarian.net/17826115/xorg.conf
** Description changed:
After installing the latest ati proprietary driver (8.9) under Ubuntu
Hardy, I faced several difficulties to properly configure 2 displays
(laptop + external EIZO FlexScan S2031W). After reading xrandr related
webpages [1] [2] [3] I concluded that the best way is to erase my
current xorg.conf file and build it from the scratch.
Finally I managed to get (almost) what I wanted using xrandr. I have a
Big Desktop which spans vertically along the 2 displays. All dynamic
xrandr command (like turning on/off a display) as well as screen
rotation (I mean orientation) work perfectly. Even compiz works fine
(some known video flickering issues are still present).
+
Issues:
(a) One thing that (according to [ ]) is missing from xrandr is the
support for 2 independent "Screens", one for each display.
(b) The real problem is some display distortion within and around the
mouse pointer only while moving it along specific virtual "columns" (or
name them vertical stripes!?) in both displays. It gives the impression
that it is a systematical error that appears in equally distanced (?)
vertical stripes.
(c) In addition, the external display when rotated is too slow for just
2D rendering (like scrolling a webpage or the text in a word processing
software). I have set the Virtual in xorg.conf size to match the sum of
the required maximum resolution(s) supported by the two monitors (width:
1680 x height: 800+1050). I read in ati X1250's specifications [4]
(under the section 2D Acceleration Features): Supports a maximum
resolution of 2048x1536 @ 32bpp (driver-limited).
+
Questions:
For (a): Any information if this planend to be fixed soon?
For (b): Can this be explained/fixed?
- Sor of a question For (c): I suppose this really means that the X1250 graphic
card cannot achiece 2D acceleration over "1536" height-pixels (?) :-(
