KDE Desktop Effects + Fglrx
in [Slackware]

From: Aaron W. Hsu on 18 Jun 2010 23:51 Has anyone tried the 10.6 Catalyst ATI Proprietary driver with Slackware64 13.1 and KDE? While the driver seems to be working fine, to the effect that I can run 3- d games just fine with it and get some good 3-d tests going, KDE doesn't seem able to use Desktop Effects. When I try to enable compositing, it just fails without any error messages that I can find. I'd like some pointers on where to start looking to debug this and perhaps a solution if someone has already figured this stuff out. Thanks in advance, Aaron W. Hsu

I just d/l'ed and installed 10.5 a few days ago, I must have just missed the 10.6 release by hours. Anyway, have you tried going to any of the ATI web forums? I had to do that to find a patch to compile 10.5 on 2.6.33.4, but while looking around I got them impression there are a lot of helpful people there. I don't use KDE, so I can't help you with any KDE-specific stuff, sorry. Jim

So, I've never had a problem installing any of the ATI drivers, as I just use the --buildpkg Slackware/All target, and make sure that I have the right environment set up to build the packages. They build, and everything goes fine for me. Apparently there must be something wrong with functionality checks or something. I find somewhere, after searching around for a while, that disabling the functionality checks allows KDE to use the Desktop Effects without problems. However, I did discover that the amount of graphics power that you need to run two large desktops in a multi-desktop configuration with Desktop Effects enabled is too much for my card. :-) So...I've just gone back to not using the desktop effects and using Xinerama with dual-head. That seems to work well and I still get good performance with my 3-d related applications. Aaron W. Hsu

I was happy to see that the 10.6 ATI Proprietary drivers compile successfully against kernel 2.6.33.5 without the patch, but I'm obliged to enable and then disable Functionality Checks in KDE in order to get them working, and that after every login. I don't know if ATI can still be considered a Canadian company, but that's my reason for sticking with them. The ATI drivers generally work very well for me, and I dual-boot between Linux and Windows XP for specific reasons. That being said, I concur with Martin that ATI (AMD?), are too quick in dropping support for older cards (bye bye my 9800 Pro), and are slow to react to Linux kernel incompatibilities. We'll see which version will eventually compile against kernel 2.6.34; I was kinda hoping 10.6 would, but alas, no. But as far as 2D and 3D performance is concerned, 10.6 is a big improvement over 10.5, at least in my case. -- Richard Herbert Registered Linux user 14329 If there's nothing wrong with me, then ... there must be something wrong with the Universe!
