I'm not sure exactly what the problem is, but I am experiencing some flickering with the NVidia-provided kernel and GLX drivers. Here's the configuraton:
- Dell Dimension 4500 - Two NVidia GeForce 4 MX 420 cards, one AGP and one PCI - two identical Samsung SyncMaster 1200NF monitors - Debian 3.0 unstable, kernel 2.4.18-bf2.4 - NVidia drivers 1.0-3123 - XFree86 4.2.1 - both screens running at 1600x1200x24 @ 85Mhz - no dotclocks/modelines defined in XF86Config The problem is that horizontal lines, one pixel in width, between 1/4 inch and 1.5 inches in length, are flickering on the screen. This only occurs on the screen being driven by the AGP card. They appear to be partial scanlines displaced to the right, since when the screen has the same color all the way across any given scanline the problem goes away. The color of the lines is always that of some part of the scanline to the left. The worst situation occurs when the screen in question has one color on the left half and another on the right. Due diligence: - yes, the driver is set to nvidia in the XF86Config-4 file for both cards - I have switch the cables and the problem occurs on whichever monitor is connected to the AGP card - the problem does not occur with XFree86's nv driver, but I can't just use that since I am doing work in OpenGL And the usual irritation: this problem does not occur under Windows. Any thoughts on things to try to fix the problem? Is this a symptom of my card going bad? Has anyone else experienced this with a similar configuration? --Greg -- To UNSUBSCRIBE, email to [EMAIL PROTECTED] with a subject of "unsubscribe". Trouble? Contact [EMAIL PROTECTED]
