Just a quick one here. I see Slackware-14.0 ships llvm. Is mesa compiled --with-llvm for older crappier half assed 2007 ATI cards like my RS600 (aka RS690, aka X1250 series, aka ???) which gains an improvement by getting llvm to replace it's vertex shader? Do I have to do anything special to set it up?
Of what update are you talking about? The one from 13.37 to 14.0? In this case, you'll need to rerun the amd installer as it needs to recompile the kernel module for the kernel found on 14.0. Make sure your kernel sources are there and properly configured (you should need to run "make mrproper" inside the kernel source directory).
Also note that when you install fglrx it overwrites libGL.so so, if you uninstall it, you'll need to reinstall the mesa package to make sure you have a libGL.so on your system.
You could be right. I haven't tested that, or haven't even figured how to test it.
I was told by developers on phoronix to set up with llvm as my card had basically no vertex shader. That was 15 - 18 months ago. It affects 2D performance, I think - certainly not 2D & 3D. I did get something going, but the results were inconclusive.
ok i finally made mine to work.... however, the dumb question remains.
radeon (opensource) drivers are included in the xorg but i can't have desktop effects with radeon module loaded... apparently i need radeonhd (different set)
how can i verify if these are also included?
You should really start your own thread as business_kid already hinted if you have additional questions.
However, radeon in Xorg (contained in xf86-video-ati) != radeon in mesa != radeon in kernel. They are 3 completely different "drivers" with different purposes. I believe you still have something left behind by fglrx which is interfering with mesa (have you reinstalled mesa?), but the only way to be sure is to look at the X log file (/var/log/Xorg.0.log).
radeonhd has been merged in mainline radeon drivers some eons ago and is now deprecated.
Radeonhd is dead a long time. Whatever you are reading is simply out of date. The current situation is that xf86-video-ati (giving a radeon driver) and the radeon kernel module are the open source offering. It should provide everything - desktop effects, etc. If you have a decent (or recently decent) ATI/AMD card, you can alternatively use the fglrx (kernel module & driver supplied) which may be faster. That binary blob accepts an uninstall argument (/uninstall or --uninstall, forget which).
The handiest check to see if there's junk left about from fglrx is this
ls -l /usr/lib(64)/libGL*
Mesa libGL stuff is all 1.x (1.2, 1.3.x, 1.5.x). Fglrx uses very different numbers, and replaces these essential libs. Check what the symlinks are pointing at.
I appreciate your help... the card i have is a HD 3400 which support has been depreciated by amd with current drivers; however, they are offering support on previous version, so i installed that.
Currently it is working. I'll remove the driver and make some test with the x86-video-ati to check which one is faster.
and don't worry
will create a new thread with the findings
