Either there's just no mode for 10x7 in your VBIOS, or there is and we're throwing it away; in the latter case we should try not to. And the color thing is probably just something being naïve about channel setup, which should also be in the log. If you could file a bug about this it'd be best. > >> 2) Is there a way to benchmark > >> performance?

Vesa, 800x600, 16-bit gave me 67 seconds. Hmm. You'd normally expect 16-bit performance to be a bit better, since you're moving less data around. > I also did an update and the neomagic driver still has serious issues. > Should I post logs? Take pictures? What would help? I don't know much about the neomagic driver at all, so it'd be best to file any bugs in it upstream (bugs.freedesktop.org, xorg product, driver/neomagic component). vesa, on the other hand, I'm painfully familiar with, and it needs to work reliably anyway, so I'd like to follow up on it on bugzilla. - ajax -- fedora-test-list mailing list fedora-test-list@xxxxxxxxxx To unsubscribe: https://www.redhat.com/mailman/listinfo/fedora-test-list
