Hopefully this message will clear the air. <snip> > Brett Carter says: > "After a quick reboot to windows, looks like the results are the same > there - you can't set the gamma on the second head." To clarify: Both in windows 98SE and X setting the gamma only sets it on the primary display. It looks to me like the hardware is crippled. I'll send a message to matrox tech support and see if they indeed can confirm this. > Given all this contradiction, I'm making the following decree: > > * Brett Carter is the bug submitter.

Brett, can you confirm this? Yes, I :cannot: set the gamma on the secondary head either in windows or X. I even flashed my card to the latest bios and driver under windows just to make sure. Go ahead and close this report as "not a bug". > * If someone has a Matrox card that *can* set the gamma on the second > head, file a separate report. > > Brett has a Matrox MGA G400 AGP rev 130.

Looks like linux's pci database needs to be updated, and lspci on my box returns: 01:00.0 VGA compatible controller: Matrox Graphics, Inc. MGA G400 AGP (rev 82) But I know for a fact I've got a g450 (at least that's what the box says, and what windows reports). I'm running 2.4.18 so maybe this is reported correctly in a newer kernel. AFIK the g400 isn't even a dual-head card. So to sum things up: 1. On a matrox G450, it looks like you can't set gamma on the secondary head due to a hardware limitation. 2. This bug can be closed as "not a bug" 3. It looks like there still might be an issue with the g400, which to my knowledge isn't a dual head card. -Brett Carter
