Carl, Stan, thank you very much for your feedback. Stan: I doublechecked the boot options: They are written in lower case. So there shouldn't be a problem. In the default SUSE setup I used the driver "radeon" with no special settings. X-server startetd as configured during installation (1280 * 1024 @ 60). I have no clue about where to look at in that area... Thanks for the Ctr-Alt-F10-hint. it didn't hang during the last 2 boots, but I will check. The insteresting part is: The F10-console comes up a couple of seconds befor the x-server starts. Then the system automaticyally switches to the F7-console (X). I will have to try whether I can manage to get back to F10 before it hangs... Carl: I will try the splash=none-option. Thank you. Sorry, in my Dell-cut-down-to-basics BIOS there are only 2 performance-related settings: HyperThreading (has been switched on and off for several times, corrently it's off, never had an effect) and HDD accoustic mode (fast and loud or moderate and silent. Usually it's silent). I have NO BIOS-option to play with memory speed/latency. I have standard Infineon 400 Mhz-chips and they DID work with 9.3 and DO work with WinXP. Any further idea? I will come back to you once I had a hang while on F10-console and report what I have seen there. I have switched acpi=on, apm=on, no more apic-option (so they should be activated) and splash=none. For now I hope it soon hangs again to check F10-console ;-) Thank you very much and kind regards, Martin
