Does it detect 4MB? You can try to add "vga=788" or similar to lilo.conf or kernel parameter. But you must not compile in vesafb at that time. This way the VESA BIOS initializes the chip before the driver does. > What I need for my application(s) is > - get good resolution (ie. 1280 x 1024 in 16 bits) > - be able to display a small MPEG stream (from a > file) on the TV output and a Web Page on the VGA > output at the same time > > I would really appreciate if someone could let me know > if all this is possible / easy / complex etc. to > implement based on either directfb and/or the linux > framebuffer driver. I'm not sure if the Cyber Pro 5005 supports different output on both heads. -- Best regards, Denis Oliver Kropp .------------------------------------------. | DirectFB - Hardware accelerated graphics | | http://www.directfb.org/ | "------------------------------------------" Convergence GmbH -- Info: To unsubscribe send a mail to [EMAIL PROTECTED] with "unsubscribe directfb-users" as subject.
