Hello, all, Please pardon me if this is not quite the correct forum for this question, yet in following this list over the past week or so, I've seen quite a few questions relating to XFree86, so I can't be too far afield. Anyway, when running X, I'm troubled by "streaks" (don't know how else to describe them) at higher resolutions, which I suspect are related to the dot clocks I've chosen. Namely, the higher the clock, the more pronounced the streaking. This streaking only occurs when the mouse is near or traverses a window border. Thus, if I move the mouse on a blank background (either on the desktop or fully within a window, I do not see any streaking). So, it probably has something to do with the whole window being repainted. I've read all the documentation I can find, including VideoModes.doc several times, as well as the specs for both my monitor and card. These latter are:
Monitor: Samsung SyncMaster 4Ne (15") Max HR: 1024 Max VR: 768 Max Video Bandwidth: 65MHz H Sync: 30-50kHz V Sync: 50-100Hz (There's also a "factory preset signal timing chart" in the appendix that, if I knew how to read it, I think would give me the sync pulses. I tried asking tech support at Samsung today for the info, but the guy who could answer was out. Tomorrow, then.) Video Chipset: Trident TGUI9680-1. Programmable clocks. As for my XF86Config: Modeline "800x600" 50.00 800 856 976 1040 600 637 643 666 +hsync +vsync works great. No streaking. Modeline "960x756" 60.00 960 984 1192 1232 756 762 770 810 works okay, but some streaking, barely noticeable. I'm still working on centering the picture better. But, Modeline "1024x765" 65.00 1024 1032 1176 1344 768 771 777 806 -hsync -vsync has quite a bit of streaking when switching windows, very noticeable. This and the "800x600" are the defaults given by XF86Setup. The middle modeline is my attempt to reduce the streaking given the information in VideoModes.doc. Having little experience in this, I'm proceeding with considerable caution, although I get the impression my major concern is keeping the dot clock at or below 65MHz, the listed video bandwidth, and, of course, trying to keep the refresh rate at a reasonable level above 45Hz. Given these parameters, I'm trying to get the best resolution I can. I'd appreciate it if anyone who has had experience with the Trident chipset could give me some pointers as to how to best utilize its features in XFree86 3.2, or so pointers on how to get rid of the streaks I've been getting.
