Nouveau is modularized in all my kernels for -current. A problem arise even if I don't want to use nouveau under X: unless nouveau be blacklisted in /etc/modprobe.d/blacklist.conf at startup, - when using one of the VESA modes at startup after a while screen goes blank and I get a warning in syslog e.g: Apr 2 18:58:56 darkstar kernel: fb: conflicting fb hw usage nouveaufb vs VESA VGA - removing generic driver, - no problem when using a VGA mode (text only), this disregarding which X driver I use afterwards (I always start in console mode). But according to this page: http://nouveau.freedesktop.org/wiki/KernelModeSetting I thought nouveaufb shouldn't conflict with vesafb ? Am I wrong ? I tried with modules shipped in vanilla 2.6.33.1 as well as the last Nouveau kernel repository pulled from git: no luck in both cases. I know there are easy workarounds: either use "VGA=ask", "VGA=ext" or "VGA=normal" as a lilo.conf option or blacklist nouveau -- which doesn't hurt anyway as nouveau will be loaded at X startup anyhow. But this is still is an annoyance for newcomers as when they are trapped all they can do if they have a VESA mode in lilo.conf is launch another system or live CD/DVD and either edit lilo.conf and run lilo again or edit blacklist.conf to blacklist nouveau. But still, before kindly requesting Patrick Volkerding to blacklist nouveau in -current for the time being, I wanted to now of another way to go if possible. Thanks in advance for your answers, Didier
