Use the xvinfo utility to verify if XVideo support is available. With version 8.29.6 of the fglrx driver, you can instead use XVideo support using the VideoOverlay option may not work with recent drivers.
(Without it, you get screen corruption including underlined mouse pointers.) It works, including dualhead, 3d and video (XV) acceleration, when using the fglrx kernel module. Proprietary fglrx driver version 8.24.8 adds support for the x1400 chipset (according to ATI changelog). If you can't make it to show higher resolutions, you may try to use lower color depth - the best fonts sizes on 15.4 widescreen were achieved with 1400x1050 at 16 depth (highcolor). Note that only the physical resolutions of the VGA port and the LVDS can differ (that means that if you use clone mode, you can have a 1400x1050 internal screen and 1680x1050 external and use both of them at the same time, but the internal screen will show only a portion of the real "desktop" this area shifts when you move your mouse towards the edge of the viewport). I use this to drive projectors all the time. ( T60): use aticonfig -enable-monitor=lvds,crt1 to clone onto the VGA port. ( Z61m): Works, but only if the X-server detects something plugged in here, eg. There is also the deprecated experimental avivo driver which works, but does not yet support any 3D acceleration.ĭisplay on the internal LCD works as long as you set the monitor settings correct. On my system, the radeon driver has better 3D performance and is more stable than the radeonhd driver.
It appears that most of this work is being merged into the radeon (aka, ati) driver. There is the radeonhd which is developed based on the published specs by AMD/ATI.
