Xfree code does not have the patch, but is Xfree experiencing the bug? Xfree accesses the hardware very differently than the framebuffer drivers. I suspect that you would see this problem if you were using something else for your primary video and a Radeon for secondary. The first time you ran Xfree it would work. But when you exited and restarted Xfree it would hang when starting the secondary display. Where does XFree reset the secondary card? The code below needs to run right after the reset in the radeon driver. I added it to my Rage128 driver too but I have not observed the problem with them. Framebuffer code is different and triggers the bug the first time the secondary display is accessed. /* Fix from ATI for problem with Radeon hardware not leaving ROM enabled */ unsigned int temp; temp = INREG(RADEON_MPP_TB_CONFIG); temp &= 0x00ffffffu; temp |= 0x04 << 24; OUTREG(RADEON_MPP_TB_CONFIG, temp); temp = INREG(RADEON_MPP_TB_CONFIG); ===== Jon Smirl [EMAIL PROTECTED] __________________________________ Do you Yahoo!?
