Re: Radeon / PowerPC (iBook G4) / Help sought with weird colorization of External LCD
Hi Michel Michel Dänzer wrote: It looks like xcalib uses the XFree86-VidModeExtension extension, which Yeah I can confirm that. only exposes a single CLUT for each X protocol screen. RandR 1.2 exposes the CLUT of each CRTC individually, see the *CrtcGamma* requests in /usr/share/doc/x11proto-randr-dev/randrproto.txt.gz . It looks like the xrandr utility doesn't expose them yet though, so it/xcalib/... would need to be extended/adapted for them. Ok. Any change to the internal LCD profile affects the external monitor too. And the colours on the external monitor are pretty funky! Even without playing with gamma at all? If that's with Option MacModel ibook, you should probably file a bug at http://bugs.freedesktop.org or post to the [EMAIL PROTECTED] mailing list. Yeah trying to use the external monitor out-of-the-box, so to speak, is not great. Much worse than it was with the original Etch drivers. While they suffered from just a little bit of pink and green on white and very light gray, respectively, the new drivers are resulting in a *really* washed-out look. I've been looking at some alternative ways to do dual-head like xdmx, synergy, xmove and the like. Probably go with one of these since the signal from my Toshiba's Nvidia card is quite good/compatible with my monitor. Thanks for all your assistance. I'll look into filing a bug as you suggest. Have a good one. Jarrod.

Hi Michel and Bin, The driver no longer supports traditional (Zaphod style) dualhead configurations but just RandR 1.2. See http://bgoglin.livejournal.com/9846.html or http://www.intellinuxgraphics.org/dualhead.html . Thanks very much for the assistance. I have now managed to get a dual-head setup going on the iBook with the new Xorg + new Xrandr setup. Haven't quite fixed the mouse cursor yet but hopefully that's not too hard (cheers Bin!). As far as the colours go though, correct me if I'm wrong but the new Xrandr setup uses one set of gamma gear (CLUTs?) for *both* screens. Would this indeed be the case? Which means I can no longer specify corrective profiles individually using xcalib. Any change to the internal LCD profile affects the external monitor too. And the colours on the external monitor are pretty funky! Where do I go from here? Thanks Regards, Jarrod. -- To UNSUBSCRIBE, email to [EMAIL PROTECTED] with a subject of unsubscribe. Trouble?

Re: Radeon / PowerPC (iBook G4) / Help sought with weird colorization of External LCD
Hi again, Just thought I would mention that the single head setup is not quite as fine as I first suggested. 1. The mouse pointer is kind of mirroring itself and looks very funky, but clearly not healthy. 2. Everything seems very fuzzy. Is there by any chance some anti-aliasing now happening inside X? (I have supposedly disabled font anti-aliasing in KDE). 3. There are severe blue overtones in Norman Koren's monitor test patterns. (www.normankoren.com/makingfineprints1A.html#gammachart) Any options/upgrades I should try to rectify these issues? Would any of these problems be caused by a package version mismatch? I have only upgraded xorg to experimental. The rest are still on etch stable. Thanks and cheers, Jarrod. -- To UNSUBSCRIBE, email to [EMAIL PROTECTED] with a subject of unsubscribe. Trouble?

Radeon / PowerPC (iBook G4) / Help sought with weird colorization of External LCD
Hi All, Just wondering if anyone has some insight as to why connecting an external LCD monitor through Linux (Debian Etch with 2.6.22 vanilla kernel) would produce an odd blue cast to greys and a faint pink tinge to my white? The reason I noticed the colorization is that using the exact same monitor under Mac OS X 10.4 does *not* produce the colorization. I thought it might be the ICC file OS X uses in its ColorSync setup, so I copied that to my linux drive and ran xcalib -s 1 -v myColors.icc, however, while this did change things, it hasn't set things right so to speak. The iBook uses the same port to drive both external monitors and TVs; it depends which special adapter cable you plug in. So I was wondering if there might be a setting on the Radeon card which is currently in TV mode instead of LCD mode or something similar. Is it possible to get the output of radeontools under OS X and diff it with my Linux setup?? Any and all help much appreciated.
