You might try to load nouveau module after boot - maybe something will be saved to /var/log or you could even ssh into the box and check dmesg... Marcin

When I do so, no regression is obvious from what gets reported in "dmesg". However, somehow I now do get some output: The last message I see is [drm] nouveau 0000:01:00.0: allocated 1680x1050, fb 0x40.... b0 <some pointer value> Then, nothing more. However, it really is quite strange why this error only appears in the CONFIG_NOUVEAU=y case, not in the =m case... Best, Dominik
