https://bugzilla.novell.com/show_bug.cgi?id=468865 Summary: sax needs to add option ReducedBlanking to monitor section in order for 1920x1200 modeline to work Classification: openSUSE Product: openSUSE 11.0 Version: Final Platform: x86-64 OS/Version: openSUSE 11.0 Status: NEW Severity: Normal Priority: P5 - None Component: SaX2 AssignedTo: sndirsch@novell.com ReportedBy: markgray+to-suse@puck.nac.net QAContact: sax2-maintainer-bugs@forge.provo.novell.com Found By: --- Created an attachment (id=267267) --> (https://bugzilla.novell.com/attachment.cgi?id=267267) My modified (working) xorg.conf User-Agent: Mozilla/5.0 (X11; U; Linux x86_64; en-US; rv:1.9.0.5) Gecko/2008121300 SUSE/3.0.5-0.1 Firefox/3.0.5 I just bought a new 1920x1200 monitor and X refused to use the preferred 1920x1200 resolution because it thought that the monitor did not support reduced blanking. Adding the option "ReducedBlanking" by hand to the monitor section allows it to function properly. (A google search found the solution on the gentoo bugzilla at url: http://bugs.gentoo.org/show_bug.cgi?id=135544 It is possible that it is just due to the fact that the monitor does not yet have a proper data file for sax to use. It is a 24inch Samsung Syncmaster model T240. I will be happy to supply any additional information you may need, and update the bug in case it is still present in 11.1 when I get around to updating this computer -- but adding it by hand works for me. Reproducible: Always Steps to Reproduce: 1. Buy Samsung model T240 monitor 2. Configure using SaX2 3. Scratch head overnight when 1600x1200 resolution is used instead of PreferredMode 1920x1200 Actual Results: Inferior 1600x1200 resolution used. Expected Results: SaX2 should have added the option "ReducedBlanking" to the Monitor section of xorg.conf (instead of my having to do it by myself). -- Configure bugmail: https://bugzilla.novell.com/userprefs.cgi?tab=email ------- You are receiving this mail because: ------- You are on the CC list for the bug.

From comment #6 I guess you already figured out why the option works (sounds rather kludgey:). I will eventually try 11.1 on this computer and let you know what happens. (I am waiting for an important email, and this is my mail gathering machine so it will probably not happen until later this weekend.)

I just noticed that your monitor has *not* been detected via DDC, which is probably the reason, why the validation for the reduced mode failed.

I could workaround this hardware bug by adding a monitor entry to SaX2 which references a profile, which again sets this option, but I'm rather reluctant to do this as you might understand.

I quite understand -- the machine was quite a bargain, and is incredibly fast, but the video bios has been a bit of a problem since day 1. Also the video card is in the "undocumented region" between the early radeons and the radeon HD chipsets. (But it still is a very nice machine which I am quite attached to.) -- Configure bugmail: https://bugzilla.novell.com/userprefs.cgi?tab=email ------- You are receiving this mail because: ------- You are on the CC list for the bug.
