Hello, I had the following configuration and everything worked fine: AMD 1200 on MSI Master Linux-2.4.x XFree86 4.0.2 on SuSE 7.1 nVidia M64 with 32 MB Video RAM Sony CPD400 at 1280x1024 When the nVidia card failed, I have replaced it with an ATI Radeon 7000 with 64 MB DDR RAM (lspci recognise it as ATI Technologies Inc Radeon VE QY) with only the following configuration change. XFree86 4.2 on RedHat 7.3 (as it doesn't work with XFree86 4.0.2 and I don't have needed bandwidth to download XFree86 4.2.0 binaries from xfree86.org at the moment) What a disaster! It works fabulous on 1024x768 but on 1280x1024 the window borders and bold/large characters are shaking! (slowly, very slowly), and quite frustrating if I need to use the computer for long hours. To be sure if it isn't a hardware problem I did the unthinkable, I have installed W2K (shame on me) and confirmed that it is working fine on 1280x1024 and even on 1600x1200 at 85 Hz (with the ATI provided windows drivers though). <opinion> I have considered the ATI brand as key Linux kernel developers/advocates think ATI Radeon is friendlier to open source developers than evil nVidia. I wish Radeon cards work the best with XFree86. </opinion> Choosing AGP Support and Direct Rendering Support on Linux-2.4.19-pre9aa2 didn't help (neither did I have these settings for nVidia card nor do I really need them for XFree86/KDE/XFCE desktop usage, do I??) Thanks for your time, please let me know if you need any information, or you want me to try something. I can provide the XFree86 log file on request. Hari, harisri@telstra.com
