AMD Catalyst 9.5 Driver For Linux Released

[mathojojo]

Hello all,

First sorry for my bad english (I'm French).

Since Ubuntu Jaunty, I have some problems with dual-head on my ATI HD4850.
The problem appears to come from RandR 1.2. Aticonfig can't use --dtop or desktopsetup when randR 1.2 is enabled.

Catalyst 9.5 doesn't resolve this issue.

I disabled RandR (with this line : EnableRandR12=SFALSE in the /etc/ati/amdpcsdb file, under the right section).

But --dtop options are no more available.

I finally successfully set the dual-head via : aticonfig --xinerama=on

It works, but xinerama is not perfect (the mouse is drawed on each screen.

Is there a good way to use --dtop options with catalyst 9.5? A way to use amdcccle to set screen 2 at right of screen 1, and screen 1 at left of the screen 2 as it was easy to do with Ubuntu Intrepid 8.10?

Thank you very much for your help.

really nice driver
1080p video plays without noticeable cpu load when using opengl as output

I hope you're aware that this driver does not actually accelerate video in any way and all is done by the CPU...

well, XV = 40% load for me, openGL ~20
had higher loads under both with older versions

i don't care if it doesn't accelerate decoding, but it certainly accelerates drawing

With the same video? You can have one 1080p video use 10% CPU and another one use 90%.

Ok guys, I'll answer my own question from above. This driver does not solve the hard crash on my onboard hd 3200, kubuntu 9.04 (it was working in 8.10).

I wasted too much time, posted a bug in launchpad, looked for an ATI official bug-tracker, and there is no such a thing (you can post in an an official forums where people try to help each other, there are a few bug reports and even the maintainer of the forum switched to NVIDIA out of frustration.

I praise the efforts from ATI to help open-source drivers be developed, and I built a system around AMD/ATI as a way to say thanks, but this is too much. I'll buy a discrete NVIDIA card on sale whenever I see a good deal and be done with it.

With me, using Xv on a nice 1080 HD vid. gives out like 10-30% load on all cores (total doesn't exceed 40%). With OpenGL it's pretty much the same (a little higher). However, Xv is rather unusable under Compiz (CPU usage spikes to 80-100% and video becomes a slideshow). OpenGL does not have this problem, but mplayer sometimes seg. faults.

Well, it *has* had experimental XvMC since 8.10. It was said that it didn't work out of the box, dunno how it works now. Open drivers will be getting XvMC with Gallium. I suspect you probably can forget XvBA for good, at best we'd probably get some VDPAU implementation on open drivers on the ATi chipset.

Problem with XvMC: it does not deal with anything else than MPEG2. 720p/1080p video is MPEG4/AVC :P In today's PCs, acceleration for MPEG2 (DVDs) is a bit useless.

Well, I'm really the only one here, who hopes to use his ATI hardware to get a dual-head display??? Is it a crazy idea??

Again.. If you can, Thx for your help
