In the past I could recreate the <xorg.conf> file with “sax2 -r -m 0=radeon” (or fglrx). After the most recent update to 2.6.34.7-0.3-desktop x86_64, sax2 has disappeared.
I then tried “Xorg -configure”. No joy there: tt crashed.
What is now the recommended way to configure the display system?
Sax1 is no more none wanted to maintain it.
Tell use about your video hardware and maybe read
opensuse v11.3
linux 2.6.34.7-0.3-desktop x86_64
ATI radeon hd3200 (built into motherboard)
The open source radeon driver cannot be used on two of the workstations because:
I then tried the custom build that has worked nicely in the past. It fails to build with a compiler error. (Next stop: ATI support).
I built the standard fglrx but for no observable reason it did not enable video acceleration. 
Even with a quad core CPU 1600x1200 is slooooow without acceleration.

I chose linux because of its reputed stability. Over the last 4 months there has been one problem after another with every kernel update. Now I have two workstations that are barely limping along because of this video driver crud.
Another highly annoying aspect: The five workstations here have almost identical hardware, motherboard, CPU, RAM. The only difference are the disk drivers; some are SATA, some SCSI. Yet every computer has different problems for the same updates.
TNevertheless, Linux is better than Windows.
