ATI drivers for Linux

Linux ATI driver for Radeon, FireGL and Mobility boards

How much is the speed gain versus the opensource drivers?

I've noticed appx 40% speed gain with ATI fglrx vs open source drivers. However, there are issues with freezing/garbage after suspend, garbage when resizing desktop (ctrl-alt-plus, ctrl-alt-minus), and garbage while using VMware.

Status

Current version: 8.14.13 (9th June 2005)

Problems & Help

Driver Version 8.8.25: The following patch may be needed for kernels >= 2.6.10: http://www.rage3d.com/board/showthread.php?t=33798874

Driver Version 8.8.25: For kernels >= 2.6.11-rc1 try the following patch: http://www.gehirn.org.uk/wiki/images/8.8.25-kernel-2.6.11+.patch

If the ATI driver works only without the hardware acceleration, take into consideration that fglrx_dri.so was linked against libstdc++.so.5 which may not be present if your system uses gcc-3.4. To fix this, compile gcc-3.3.5 and copy libstdc++.so.5* to /usr/lib and update the dynamic linker cache.

Troubles using software suspend : when the computer comes back of suspend, X only displays a garbaged image and the computer is frozen. You have to install vbetool and use it to save/restore the video card state. If you use swsusp2 scripts you just have to uncomment "EnableVbetool yes" in /etc/hibernate/hibernate.conf. Tested with kernel 2.6.10, Debian packaged ATI drivers and swsusp2 patch on a IBM Thinkpad T42p.

This does not seem to work on the T43: The machine displays a sligthly garbaged image and is frozen upon resume. (It does work as long as the fglrx kernel driver is not inserted.) (Tested on kernel 2.6.12-rc6 with suspend2 2.1.9 and ATI driver version 8.14.13)
