Fresh openSUSE 13.1 x64 install: KDE issues - kmix and compositing

$

Hi there,

I installed 13.1 x64 yesterday using the network installer, to my Phenom2 X6 1090T, 8GB, GeForce GTX560Ti based box - everything seems to have installed cleanly, but I'm experiencing a couple of issues with the default KDE 4.11.3.

First and most serious problem is the use of compositing for desktop effects - I simply cannot set compositing type to OpenGL of any flavour, as after less than a minute the desktop becomes unusably slow. Xrender works, but of course some of the effects require OpenGL to work. It is worth noting that on the exact same box, openSUSE 12.2 and KDE 4.8.4 and KDE 4.9.5 worked flawlessly with OpenGL compositing. I've blacklisted nouveau as recommended, and tried various tweaks of xorg.conf, but at this point am stumped.

Second and much less serious, but still annoying is the refusal of kmix to display all the controls for my Infrasonic Quartet PCI audio card. This is a Via ICE1724HT based high-end multichannel in/out audio card. Of note is that under openSUSE 12.2/KDE 4.9.5 kmix even listed it as an 'Infrasonic Quartet' and showed me all the controls - those controls do not appear under this latest iteration of kmix, despite me doing some tricks with .asoundrc to try and coerce kmix into doing so. I've tried qasmixer, which does show the controls, but has a dreadful UI that cannot save or remember the position of control elements, and also Volti (doesn't show controls), and alsamixergui, which again does show them but has the worst UI of all. I've noted that the XFCE mixer app looks to be exactly what I want, but I don't want XFCE. I really do need access to the controls, as there are times I need to monitor the inputs or not monitor the inputs, and also change the sample rate depending on the software I'm working with.

So is anyone willing to help me, particularly with the graphics issue?

On first impressions openSUSE 13.1 could score 5 from 5 were it not for these regressions. I am running it on another machine (old slow laptop), but only as a DLNA media and security server with an LXDE desktop. It is working flawlessly on there, but with KDE being the preferred desktop user experience I sadly have to say KDE has regressed from 4.8 and 4.9 to this 4.11 release. I see an update to KDE 4.12.0 is available, but I'd like to learn if that update fixes some of the issues with 4.11.3 before I dedicate download bandwidth to installing that.

Cheers,
Chris W, NZ
