I would like to inform you that I have found the solution to the above-mentioned problems. These problems occur in several branches of XFree86 starting from about one-and-a-half months ago, I believe. The removal of two lines of code was all that was necessary to correct EVERY one of the above problems. It is as follows. File: xc/programs/Xserver/hw/xfree86/drivers/ati/radeon_dri.c Lines: 710 and 711 I understand that this code may be beneficial for some people, but I do not understand enough about X or the various registers of the graphics hardware to actually 'fix' the code and these lines wreak havok on my system. -Jonathan Thambidurai ------------------------------------------------------- This sf.net email is sponsored by:ThinkGeek Welcome to geek heaven. http://thinkgeek.com/sf _______________________________________________ Dri-devel mailing list [EMAIL PROTECTED] https://lists.sourceforge.net/lists/listinfo/dri-devel
