Re[2]: [gentoo-user] intelfb and 945GM

[Sergey Kobzar]

Hi Wael,

Thanks for help.

According to http://gentoo-wiki.com/HOWTO_fbsplash:

uvesafb - a newer (>=2.6.23) generic, _non-accelerated_ driver that
supports additional features such as custom resolutions. Unlike other
drivers, it requires a userspace daemon called v86d to run (provided
in the sys-apps/v86d package)

intelfb - an _accelerated_ driver for Intel chipsets


That's why I selected intelfb. Any chance to get it working or it's
more easy to forget about it?
