I never knew about this requirement,

Whoever is responsible for commenting all the files in xorg.conf.d/ should have added a README there. As not every distro populates xorg.conf.d/ (actually none that I can remember other than openSUSE), I have to think the presence of anything there at all may well be an exclusive openSUSE feature, and a README addition is worth an openFATE try.

despite extensive fiddling with various options in these files to fix a graphics problem on my own machine in recent years. Now I know I'd like to have one last try, but how do I go about finding out what to put in the monitor resolution lines. E.g. on your site above, the example shows a line like this: DisplaySize 338 270 # 096 DPI @ 1280x1024 My own laptop has a resolution of 1280x800. Don't know about the rest.

What you need depends entirely on why you're trying to override automagic. What is the problem you're trying to solve?

Let your computer do the math work :-)

$ xmode -x 1200 -y 800 122 140 Modeline "1200x800" 200.26 1200 1296 1424 1648 800 801 804 868

That is on my box, you may have other values. Try it!

Why such a bother with modeline calculation? Xorg calculates suitable modelines automatically. I cannot remember _EVER_ solving any problem by putting a modeline in any Xorg config file (unlike for XFree86), though I do remember multiple attempts to do so.

The above modeline is the same as what I get. I'll try creating these files with the minimum info and see if I have any luck. Will be at least a few days before I can ascertain anything though. I'm a bit reluctant to dredge up my long history of problems especially since I'm hijacking somebody else's thread here. But in brief: my laptop's Mobility Radeon 9700 card doesn't play well with the radeon drivers ever since version 11.something of openSUSE around the time KMS was introduced. It's not a problem with the individual card since I had exactly the same issues with a desktop machine and a Radeon 9600 card (which the 9700 is based on). I've tried fresh installs but always the same thing happens. Everything runs fine for the first few days, then the system locks up, the screen flashes blank for a moment and comes back but everything's frozen. Only a magic keys reboot can get me out. Once this cycle commences it becomes more frequent, like there's some memory corruption because on reboots it often happens again very soon. I've tried all kinds of things with x.org files, KDE/compositing settings, nomodeset, etc. I've posted on forums, contributed to various bug reports and recently started another on Bugzilla (unanswered, see here: https://bugzilla.novell.com/show_bug.cgi?id=817528), but I'm hitting a brick wall for about 3 or 4 years now. The laptop otherwise works fine but the only workaround is to disable 3D via the xorg 50-device file, causing the machine to run on software drivers with higher fan speed and noise and slowdowns that sometimes render it almost unusable. That's already more than brief. What I really need is for someone to look at some log files (such as that attached to the above bug report) and see if they hold any clues. -- To unsubscribe, e-mail: opensuse+unsubscribe@opensuse.org To contact the owner, e-mail: opensuse+owner@opensuse.org
