Thanks in advance, > Chipset: 945GM >>From openSUSE 11.3 on i845G http://fm.no-ip.com/Tmp/Linux/Xorg/xinitrc-113-t2240-1600x1200v1920 should serve as a template for you to construct an /etc/X11/xinit/xinitrc file with required xrandr commands included to be run _before_ $WINDOWMANAGER starts. Note that the reason for preferring high refresh rates on CRT displays does not exist on flat panel displays. I've yet to find any flat panel that doesn't work perfectly in close proximity to 60 if not exactly 60. So, K.I.S.S., and use CVT and/or GTF without bothering with refresh spec. 'gtf 800 480' will default to 60, which would invariably be just right. Supposedly xorg.conf can still be used with legacy Intel chips to do the same things as xinitrc/xrandr do, but I've yet to confirm it, succeeding only on MGA so far. -- "The wise are known for their understanding, and pleasant words are persuasive."
