(Get the code!)
Hi, I'm running Sept 18th's Intrepid, trying to get my Samsung external (1680x1050) to work with my Toshiba laptop (1280x800), as it did in Hardy.
First, the fglrx driver didn't work at all, ie the old xorg.conf failed. So I'm trying the radeon or ati drivers, whose problems seem to be the same:
The Samsung is showing up with resolution 1280x960 (or other suboptimal), despite all attempts to force otherwise.
The latest attempt is attached. (Similar problems occur with Xinerama off).
The relevant lines from the Xorg log are, I believe,
(II) RADEON(1): Output: VGA-0, Detected Monitor Type: 1
finished output detect: 0
finished all detect
before xf86InitialConf
(II) RADEON(1): Output: VGA-0, Detected Monitor Type: 1
in RADEONProbeOutp
(II) RADEON(1): Adding Screen mode: 1680x1050
(II) RADEON(1): Adding Screen mode: 1280x1024
(II) RADEON(1): Adding Screen mode: 1280x800
(II) RADEON(1): Adding Screen mode: 1024x768
(II) RADEON(1): Adding Screen mode: 800x600
(II) RADEON(1): Total number of valid Screen mode(s) added: 5
(II) RADEON(1): Output VGA-0 connected
(II) RADEON(1): Using fuzzy aspect match for initial modes
(II) RADEON(1): Output VGA-0 using initial mode 1280x960
Please let me know if this issue should be raised elsewhere.
