brightness too high
Last modified: 2007-11-30 17:10:35 EST
Description of problem: graphical installation has too high brightness Version-Release number of selected component (if applicable): How reproducible: Simply try to install Fedora dist. Steps to Reproduce: 1.start with CD#1 2.choose graphical mode 3. Actual results: Also after installation the brightness still remain too high Expected results: obvious Additional info: The right monitor (Benq FP767) and graphic adapter card (ATI Radeon 9200) are recognized by installation program.
Same problem found with a Radeon 9000 Pro cards and Philips 104B monitor.
Are either or both of these displays flat panels, or are they CRTs? All Radeon hardware that I have here looks exactly the same on my monitors, with no difference of brightness. I suspect the problem is hardware specific to hardware I do not have any physical access to, so I'm not sure what if anything I can do. I recommend reporting the problem upstream to http://bugs.xfree86.org also, with full details, and attaching your X config file, log file, and the exact brand make/model of video card. It's possible that the cards having problems are not "Built by ATI" cards or something, and that might be why I can not reproduce this, as all my hardware is real built by ATI hardware. If you do report this upstream as well, please put the bug report URL here for me to track also. TIA
Oops, monitor is actually a Philips 109B4 (CRT screen) and the graphics card is a Gigabyte Maya Radeon 9000 Pro.
Ok, I suspect that the different brand of video card might be related. I do not have access to that brand/model of Radeon, so you might want to also report this to XFree86.org as per my suggestion in comment #2 above, as that will make more eyes see the problem, and perhaps someone else can reproduce it. Please update this report with your upstream bug URL. In the mean time, I'll keep my eyes peeled on CVS commits for any updates that seem relevant. TIA
Oops, I set this to 'DEFERRED' by accident. Got 2 bug reports mixed up. I believe this bug is a duplicate of bug #112073 which I just fixed in the latest rawhide builds. Raffaele, could you please test the latest rawhide XFree86 build 4.3.0-59, and indicate if this problem is resolved now or still present?
Closing as "CURRENTRELEASE - problem resolved in Fedora Core 2 with X.Org X11 6.7.0, by patch integrated from Hui Yu at ATI which resolves an ASIC specific issue present in 9200 variants and a few other chips.
