John, David: Thanks for your input. I am using the standard opensuse ati driver called "radeon". I've been using this driver for several years with the same card but with an 17" CRT monitor with resolution 1024x768. I never experienced any problem with it. My TFT is set according to the manufacturer's instructions (20" monitor, 1400x1050 at 60 Hz. The only thing I can think of that the graphics card is not powerful enough for changing the screen fast. I don't think it is trying to change resolution. I will try the monitor with another more powerful card. Thanks again, IG <br><br>________________________________________________________<br><a href="http://ad.hu.doubleclick.net/clk;208503223;30622949;z?http://www.t-home.hu/lakossagi/tv/iptv/dijcsomagok_uj_elofizetoknek/csaladi/reszletek"> Tudtad, hogy T-Home IPTV Családi csomagban az m1-en és a TV6-on is élőben nézheted a Bajnokok Ligáját? </a> -- To unsubscribe, e-mail: opensuse+unsubscribe@opensuse.org For additional commands, e-mail: opensuse+help@opensuse.org
