My board is GX1 with CS5530. Award bios. Vanilla kernel 2.6.23.1. I use our own test program. Here is the right image: http://www.pxe.ru/ban/gx1fb/gx1fb01.JPG When I move mouse cursor over the "line of corruption", top part of the image becomes corrupted (800x600-8bit): http://www.pxe.ru/ban/gx1fb/gx1fb02.JPG This is the biggest possible corruption: http://www.pxe.ru/ban/gx1fb/gx1fb03.JPG I'm pretty shure demo program doesn't touch top area of framebuffer when cursor is over the "line of corruption". And I can "restore" image by moving mouse over corrupted area. I.e. image restores when demo program writes data to damaged area of framebuffer and corrupted again when demo program writes data near the "line of corruption". Here is the same problem in 16 bit color: http://www.pxe.ru/ban/gx1fb/gx1fb04.JPG The "line of corruption" in 16bit mode is higher (red arrow). And there is one more damage - look at the text in the line marked with green arrow. And second problem. Timings seems not working. I tried to pass "mode=800x600-8@60" and "mode=800x600-8@75" while loading gx1fb and fbset report correct timings for this rates. But monitor always reports 85Hz. This board works right (without image corruption and monitor reports 60Hz when I ask for 60Hz) with 2.4 series kernel and nsc framebuffer driver. This board works right (without image corruption and monitor reports 60Hz) with 2.6.23.1 kernel and VESA driver in svgalib. Thanks for your help. -- Andrey ------------------------------------------------------------------------- This SF.net email is sponsored by: Microsoft Defy all challenges.
